I have a database with account numbers and card numbers. I match these to a file to update any card numbers to the account number so that I am only working with account numbers.
I created a view linking the table to the account/card database to return the Table ID and the related account number, and now I need to update those records where the ID matches the Account Number.
This is the Sales_Import table, where the account number field needs to be updated:
LeadID
AccountNumber
147
5807811235
150
5807811326
185
7006100100007267039
And this is the RetrieveAccountNumber table, where I need to update from:
LeadID
AccountNumber
147
7006100100007266957
150
7006100100007267039
I tried the below, but no luck so far:
UPDATE [Sales_Lead].[dbo].[Sales_Import]
SET [AccountNumber] = (SELECT RetrieveAccountNumber.AccountNumber
FROM RetrieveAccountNumber
WHERE [Sales_Lead].[dbo].[Sales_Import]. LeadID =
RetrieveAccountNumber.LeadID)
It updates the card numbers to account numbers, but the account numbers get replaced by NULL
I believe an UPDATE FROM with a JOIN will help:
MS SQL
UPDATE
Sales_Import
SET
Sales_Import.AccountNumber = RAN.AccountNumber
FROM
Sales_Import SI
INNER JOIN
RetrieveAccountNumber RAN
ON
SI.LeadID = RAN.LeadID;
MySQL and MariaDB
UPDATE
Sales_Import SI,
RetrieveAccountNumber RAN
SET
SI.AccountNumber = RAN.AccountNumber
WHERE
SI.LeadID = RAN.LeadID;
The simple Way to copy the content from one table to other is as follow:
UPDATE table2
SET table2.col1 = table1.col1,
table2.col2 = table1.col2,
...
FROM table1, table2
WHERE table1.memberid = table2.memberid
You can also add the condition to get the particular data copied.
For SQL Server 2008 + Using MERGE rather than the proprietary UPDATE ... FROM syntax has some appeal.
As well as being standard SQL and thus more portable it also will raise an error in the event of there being multiple joined rows on the source side (and thus multiple possible different values to use in the update) rather than having the final result be undeterministic.
MERGE INTO Sales_Import
USING RetrieveAccountNumber
ON Sales_Import.LeadID = RetrieveAccountNumber.LeadID
WHEN MATCHED THEN
UPDATE
SET AccountNumber = RetrieveAccountNumber.AccountNumber;
Unfortunately the choice of which to use may not come down purely to preferred style however. The implementation of MERGE in SQL Server has been afflicted with various bugs. Aaron Bertrand has compiled a list of the reported ones here.
Generic answer for future developers.
SQL Server
UPDATE
t1
SET
t1.column = t2.column
FROM
Table1 t1
INNER JOIN Table2 t2
ON t1.id = t2.id;
Oracle (and SQL Server)
UPDATE
t1
SET
t1.colmun = t2.column
FROM
Table1 t1,
Table2 t2
WHERE
t1.ID = t2.ID;
MySQL
UPDATE
Table1 t1,
Table2 t2
SET
t1.column = t2.column
WHERE
t1.ID = t2.ID;
For PostgreSQL:
UPDATE Sales_Import SI
SET AccountNumber = RAN.AccountNumber
FROM RetrieveAccountNumber RAN
WHERE RAN.LeadID = SI.LeadID;
Seems you are using MSSQL, then, if I remember correctly, it is done like this:
UPDATE [Sales_Lead].[dbo].[Sales_Import] SET [AccountNumber] =
RetrieveAccountNumber.AccountNumber
FROM RetrieveAccountNumber
WHERE [Sales_Lead].[dbo].[Sales_Import].LeadID = RetrieveAccountNumber.LeadID
I had the same problem with foo.new being set to null for rows of foo that had no matching key in bar. I did something like this in Oracle:
update foo
set foo.new = (select bar.new
from bar
where foo.key = bar.key)
where exists (select 1
from bar
where foo.key = bar.key)
Here's what worked for me in SQL Server:
UPDATE [AspNetUsers] SET
[AspNetUsers].[OrganizationId] = [UserProfile].[OrganizationId],
[AspNetUsers].[Name] = [UserProfile].[Name]
FROM [AspNetUsers], [UserProfile]
WHERE [AspNetUsers].[Id] = [UserProfile].[Id];
For MySql that works fine:
UPDATE
Sales_Import SI,RetrieveAccountNumber RAN
SET
SI.AccountNumber = RAN.AccountNumber
WHERE
SI.LeadID = RAN.LeadID
Thanks for the responses. I found a solution tho.
UPDATE Sales_Import
SET AccountNumber = (SELECT RetrieveAccountNumber.AccountNumber
FROM RetrieveAccountNumber
WHERE Sales_Import.leadid =RetrieveAccountNumber.LeadID)
WHERE Sales_Import.leadid = (SELECT RetrieveAccountNumber.LeadID
FROM RetrieveAccountNumber
WHERE Sales_Import.leadid = RetrieveAccountNumber.LeadID)
In case the tables are in a different databases. (MSSQL)
update database1..Ciudad
set CiudadDistrito=c2.CiudadDistrito
FROM database1..Ciudad c1
inner join
database2..Ciudad c2 on c2.CiudadID=c1.CiudadID
Use the following block of query to update Table1 with Table2 based on ID:
UPDATE Sales_Import, RetrieveAccountNumber
SET Sales_Import.AccountNumber = RetrieveAccountNumber.AccountNumber
where Sales_Import.LeadID = RetrieveAccountNumber.LeadID;
This is the easiest way to tackle this problem.
MS Sql
UPDATE c4 SET Price=cp.Price*p.FactorRate FROM TableNamea_A c4
inner join TableNamea_B p on c4.Calcid=p.calcid
inner join TableNamea_A cp on c4.Calcid=cp.calcid
WHERE c4..Name='MyName';
Oracle 11g
MERGE INTO TableNamea_A u
using
(
SELECT c4.TableName_A_ID,(cp.Price*p.FactorRate) as CalcTot
FROM TableNamea_A c4
inner join TableNamea_B p on c4.Calcid=p.calcid
inner join TableNamea_A cp on c4.Calcid=cp.calcid
WHERE p.Name='MyName'
) rt
on (u.TableNamea_A_ID=rt.TableNamea_B_ID)
WHEN MATCHED THEN
Update set Price=CalcTot ;
update from one table to another table on id matched
UPDATE
TABLE1 t1,
TABLE2 t2
SET
t1.column_name = t2.column_name
WHERE
t1.id = t2.id;
The below SQL someone suggested, does NOT work in SQL Server. This syntax reminds me of my old school class:
UPDATE table2
SET table2.col1 = table1.col1,
table2.col2 = table1.col2,
...
FROM table1, table2
WHERE table1.memberid = table2.memberid
All other queries using NOT IN or NOT EXISTS are not recommended. NULLs show up because OP compares entire dataset with smaller subset, then of course there will be matching problem. This must be fixed by writing proper SQL with correct JOIN instead of dodging problem by using NOT IN. You might run into other problems by using NOT IN or NOT EXISTS in this case.
My vote for the top one, which is conventional way of updating a table based on another table by joining in SQL Server. Like I said, you cannot use two tables in same UPDATE statement in SQL Server unless you join them first.
This is the easiest and best have seen for Mysql and Maria DB
UPDATE table2, table1 SET table2.by_department = table1.department WHERE table1.id = table2.by_id
Note: If you encounter the following error based on your Mysql/Maria DB version "Error Code: 1175. You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column To disable safe mode, toggle the option in Preferences"
Then run the code like this
SET SQL_SAFE_UPDATES=0;
UPDATE table2, table1 SET table2.by_department = table1.department WHERE table1.id = table2.by_id
it works with postgresql
UPDATE application
SET omts_received_date = (
SELECT
date_created
FROM
application_history
WHERE
application.id = application_history.application_id
AND application_history.application_status_id = 8
);
update within the same table:
DECLARE #TB1 TABLE
(
No Int
,Name NVarchar(50)
,linkNo int
)
DECLARE #TB2 TABLE
(
No Int
,Name NVarchar(50)
,linkNo int
)
INSERT INTO #TB1 VALUES(1,'changed person data', 0);
INSERT INTO #TB1 VALUES(2,'old linked data of person', 1);
INSERT INTO #TB2 SELECT * FROM #TB1 WHERE linkNo = 0
SELECT * FROM #TB1
SELECT * FROM #TB2
UPDATE #TB1
SET Name = T2.Name
FROM #TB1 T1
INNER JOIN #TB2 T2 ON T2.No = T1.linkNo
SELECT * FROM #TB1
I thought this is a simple example might someone get it easier,
DECLARE #TB1 TABLE
(
No Int
,Name NVarchar(50)
)
DECLARE #TB2 TABLE
(
No Int
,Name NVarchar(50)
)
INSERT INTO #TB1 VALUES(1,'asdf');
INSERT INTO #TB1 VALUES(2,'awerq');
INSERT INTO #TB2 VALUES(1,';oiup');
INSERT INTO #TB2 VALUES(2,'lkjhj');
SELECT * FROM #TB1
UPDATE #TB1 SET Name =S.Name
FROM #TB1 T
INNER JOIN #TB2 S
ON S.No = T.No
SELECT * FROM #TB1
try this :
UPDATE
Table_A
SET
Table_A.AccountNumber = Table_B.AccountNumber ,
FROM
dbo.Sales_Import AS Table_A
INNER JOIN dbo.RetrieveAccountNumber AS Table_B
ON Table_A.LeadID = Table_B.LeadID
WHERE
Table_A.LeadID = Table_B.LeadID
MYSQL (This is my preferred way for restoring all specific column reasonId values, based on primary key id equivalence)
UPDATE `site` AS destination
INNER JOIN `site_copy` AS backupOnTuesday
ON backupOnTuesday.`id` = destination.`id`
SET destdestination.`reasonId` = backupOnTuesday.`reasonId`
This will allow you to update a table based on the column value not being found in another table.
UPDATE table1 SET table1.column = 'some_new_val' WHERE table1.id IN (
SELECT *
FROM (
SELECT table1.id
FROM table1
LEFT JOIN table2 ON ( table2.column = table1.column )
WHERE table1.column = 'some_expected_val'
AND table12.column IS NULL
) AS Xalias
)
This will update a table based on the column value being found in both tables.
UPDATE table1 SET table1.column = 'some_new_val' WHERE table1.id IN (
SELECT *
FROM (
SELECT table1.id
FROM table1
JOIN table2 ON ( table2.column = table1.column )
WHERE table1.column = 'some_expected_val'
) AS Xalias
)
Summarizing the other answers, there're 4 variants of how to update target table using data from another table only when "match exists"
Query and sub-query:
update si
set si.AccountNumber = (
select ran.AccountNumber
from RetrieveAccountNumber ran
where si.LeadID = ran.LeadID
)
from Sales_Import si
where exists (select * from RetrieveAccountNumber ran where ran.LeadID = si.LeadID)
Inner join:
update si
set si.AccountNumber = ran.AccountNumber
from Sales_Import si inner join RetrieveAccountNumber ran on si.LeadID = ran.LeadID
Cross join:
update si
set si.AccountNumber = ran.AccountNumber
from Sales_Import si, RetrieveAccountNumber ran
where si.LeadID = ran.LeadID
Merge:
merge into Sales_Import si
using RetrieveAccountNumber ran on si.LeadID = ran.LeadID
when matched then update set si.accountnumber = ran.accountnumber;
All variants are more-less trivial and understandable, personally I prefer "inner join" option. But any of them could be used and developer has to select "better option" according to his/her needs
From performance perspective variants with join-s are more preferable:
Oracle 11g
merge into Sales_Import
using RetrieveAccountNumber
on (Sales_Import.LeadId = RetrieveAccountNumber.LeadId)
when matched then update set Sales_Import.AccountNumber = RetrieveAccountNumber.AccountNumber;
For Oracle SQL try using alias
UPDATE Sales_Lead.dbo.Sales_Import SI
SET SI.AccountNumber = (SELECT RAN.AccountNumber FROM RetrieveAccountNumber RAN WHERE RAN.LeadID = SI.LeadID);
I'd like to add one extra thing.
Don't update a value with the same value, it generates extra logging and unnecessary overhead.
See example below - it will only perform the update on 2 records despite linking on 3.
DROP TABLE #TMP1
DROP TABLE #TMP2
CREATE TABLE #TMP1(LeadID Int,AccountNumber NVarchar(50))
CREATE TABLE #TMP2(LeadID Int,AccountNumber NVarchar(50))
INSERT INTO #TMP1 VALUES
(147,'5807811235')
,(150,'5807811326')
,(185,'7006100100007267039');
INSERT INTO #TMP2 VALUES
(147,'7006100100007266957')
,(150,'7006100100007267039')
,(185,'7006100100007267039');
UPDATE A
SET A.AccountNumber = B.AccountNumber
FROM
#TMP1 A
INNER JOIN #TMP2 B
ON
A.LeadID = B.LeadID
WHERE
A.AccountNumber <> B.AccountNumber --DON'T OVERWRITE A VALUE WITH THE SAME VALUE
SELECT * FROM #TMP1
ORACLE
use
UPDATE suppliers
SET supplier_name = (SELECT customers.customer_name
FROM customers
WHERE customers.customer_id = suppliers.supplier_id)
WHERE EXISTS (SELECT customers.customer_name
FROM customers
WHERE customers.customer_id = suppliers.supplier_id);
update table1 dpm set col1 = dpu.col1 from table2 dpu where dpm.parameter_master_id = dpu.parameter_master_id;
If above answers not working for you try this
Update Sales_Import A left join RetrieveAccountNumber B on A.LeadID = B.LeadID
Set A.AccountNumber = B.AccountNumber
where A.LeadID = B.LeadID

I am using Azure SQL Data Warehouse Gen 1, and I create a partition table like this
CREATE TABLE [dbo].[StatsPerBin1](
[Bin1] [varchar](100) NOT NULL,
[TimeWindow] [datetime] NOT NULL,
[Count] [int] NOT NULL,
[Timestamp] [datetime] NOT NULL)
WITH
(
DISTRIBUTION = HASH ( [Bin1] ),
CLUSTERED INDEX([Bin1]),
PARTITION
(
[TimeWindow] RANGE RIGHT FOR VALUES ()
)
)
How should I split a partition only when there is no such boundary?
First I think if I can get partition boundaries by table name, then I can write a if statement to determine add partition boundary or not.
But I cannot find a way to associate a table with its corresponding partition values, the partition values of all partitions can be retrieved by
SELECT * FROM sys.partition_range_values
But it only contains function_id as identifier which I don't know how to join other tables so that I can get partition boundaries by table name.
Have you tried joining sys.partition_range_values with sys.partition_functions view?
Granted we cannot create partition functions in SQL DW, but the view seems to be still supported.
I know this is an out of date question, but I was having the same problem. Here is a query I ended up with that can get you started. It is modified slightly from a query for SQL Server documentation:
SELECT s.[name] AS [schema_name]
, t.[name] AS [table_name]
, p.[partition_number] AS [partition_number]
, rv.[value] AS [partition_boundary_value]
, p.[data_compression_desc] AS [partition_compression_desc]
FROM sys.schemas s
JOIN sys.tables t ON t.[schema_id] = s.[schema_id]
JOIN sys.partitions p ON p.[object_id] = t.[object_id]
JOIN sys.indexes i ON i.[object_id] = p.[object_id]
AND i.[index_id] = p.[index_id]
JOIN sys.data_spaces ds ON ds.[data_space_id] = i.[data_space_id]
LEFT JOIN sys.partition_schemes ps ON ps.[data_space_id] = ds.[data_space_id]
LEFT JOIN sys.partition_functions pf ON pf.[function_id] = ps.[function_id]
LEFT JOIN sys.partition_range_values rv ON rv.[function_id] = pf.[function_id]
AND rv.[boundary_id] = p.[partition_number]
I have 2 tables with information in them. I need to update the SelfServiceUserName column in table A_CLIENT with the value from the SubstVarValue column of the A_DEV_SUBSTVAR_VALUE table when the ClientUID and DeviceID match and the SubstVarName from the A_DEV_SUBSTVAR_VALUE table = samaccount name. Here is the query I've tried to run but I keep getting errors:
UPDATE A_CLIENT
SET SelfServiceUserName = (SELECT SubstVarValue
FROM A_DEV_SUBSTVAR_VALUE
WHERE A_DEV_SUBSTVAR_VALUE.SubstVarName = 'samaccountname')
WHERE A_CLIENT.ClientUID = A_DEV_SUBSTVAR_VALUE.DeviceID
I always write a join between the two tables first to get the rows I want side by side and make sure I have the JOIN clause correct.
SELECT p.ProductID, p.ProductName, p.Price AS OldPrice, n.Price as NewPrice
FROM Products as p
JOIN NewPrices as n on p.ProductID = n.ProductID
Once I have done that it's easy to change it into an update statement by replacing the SELECT clause with an UPDATE and SET:
UPDATE p
SET Price = n.Price
FROM Products as p
JOIN NewPrices as n on p.ProductID = n.ProductID
Note you don't alias the Price on the left side of the SET clause, because it is necessarily from the p (Product) table, so there is no ambiguity. You must still alias the Price on the right of the equals because it could be the field coming from either the p (Product) or n (NewPrice) table.
You could also use a CTE (Common Table Expression) if your SQL engine supports it:
WITH x AS (
SELECT p.ProductID, p.ProductName, p.Price AS OldPrice, n.Price as NewPrice
FROM Products as p
JOIN NewPrices as n on p.ProductID = n.ProductID
)
UPDATE x set OldPrice = NewPrice
Try something like
update a_client c
inner join a_dev_substvar_value d on
c.clientuid = d.deviceid
set
c.selfserviceusername = d.substvarvalue
where
d.substvarname = 'samaccountname';
Note, you should try avoid writing select statements in your were clause because it is run for ever row returned. This can be a big performance hit.
That should work.
Is there any way to reference updatable table in UPDATE statement in Teiid (8.4)?
For example: i have table (tag_id, value, time, active_ind). I'd like to mark all tags with non-max time.
UPDATE BUFFER buf
SET active_ind = 'N';
WHERE "time" NOT IN (
SELECT MAX("time")
FROM BUFFER
WHERE tag_id = buf.tag_id
);
But Teiid doesn't support alias for updatable BUFFER table. How can i make such update? Thanks in advance.
How about Teiid's MERGE INTO :
MERGE INTO
BUFFER(tag_id,value,time,active_ind)
(SELECT buf.tag_id,buf.value,buf.time,'N' FROM
(
BUFFER AS buf
INNER JOIN
(SELECT tag_id, MAX("time") AS max_time FROM BUFFER GROUP BY tag_id) AS m
ON buf.tag_id=m.tag_id AND buf.time<m.max_time
)
)
But as docs state:
requires the target table to have a primary key and for the target columns to cover the primary key
Hope that helps

I'm new to aws, can anyone tell me what are redshifts' equivalents to mysql commands?
show tables -- redshift command
describe table_name -- redshift command
All the information can be found in a PG_TABLE_DEF table, documentation.
Listing all tables in a public schema (default) - show tables equivalent:
SELECT DISTINCT tablename
FROM pg_table_def
WHERE schemaname = 'public'
ORDER BY tablename;
Description of all the columns from a table called table_name - describe table equivalent:
SELECT *
FROM pg_table_def
WHERE tablename = 'table_name'
AND schemaname = 'public';
Update:
As pointed by #Kishan Pandey 's answer, if you are looking for details of a schema different by public, you need to set search_path to my_schema. (show search_path display current search path)
Listing tables in my_schema schema:
set search_path to my_schema;
select * from pg_table_def;
I had to select from the information schema to get details of my tables and columns; in case it helps anyone:
SELECT * FROM information_schema.tables
WHERE table_schema = 'myschema';
SELECT * FROM information_schema.columns
WHERE table_schema = 'myschema' AND table_name = 'mytable';
Or simply:
\dt to show tables
\d+ <table name> to describe a table
Edit: Works using the psql command line client
Tomasz Tybulewicz answer is good way to go.
SELECT * FROM pg_table_def WHERE tablename = 'YOUR_TABLE_NAME' AND schemaname = 'YOUR_SCHEMA_NAME';
If schema name is not defined in search path , that query will show empty result.
Please first check search path by below code.
SHOW SEARCH_PATH
If schema name is not defined in search path , you can reset search path.
SET SEARCH_PATH to '$user', public, YOUR_SCEHMA_NAME
You can use - desc / to see the view/table definition in Redshift. I have been using Workbench/J as a SQL client for Redshift and it gives the definition in the Messages tab adjacent to Result tab.
In the following post, I documented queries to retrieve TABLE and COLUMN comments from Redshift.

WHERE c.relkind IN('r', 'v') AND d.description > ''
ORDER BY n.nspname, c.relname ;
Column Comments

You can simply use the command below to describe a table.

I tried with normal sql query
SELECT activity_shares.id FROM `activity_shares`
INNER JOIN (SELECT `activity_id` FROM `activity_shares`
GROUP BY `activity_id`
HAVING COUNT(`activity_id`) > 1 ) dup ON activity_shares.activity_id = dup.activity_id
Which gives me record id say 10 and 11
But same query I tried to do in Doctrine query builder,
$qb3=$this->getEntityManager()->createQueryBuilder('c')
->add('select','c.id')
->add('from','MyBundleDataBundle:ActivityShare c')
->innerJoin('c.activity', 'ca')
// ->andWhere('ca.id = c.activity')
->groupBy('ca.id')
->having('count(ca.id)>1');
Edited:
$query3=$qb3->getQuery();
$query3->getResult();
Generated SQL is:
SELECT a0_.id AS id0 FROM activity_shares a0_
INNER JOIN activities a1_ ON a0_.activity_id = a1_.id
GROUP BY a1_.id HAVING count(a1_.id) > 1
Gives only 1 record that is 10.I want to get both.I'm not getting idea where I went wrong.Any idea?
My tables structure is:
ActivityShare
+-----+---------+-----+---
| Id |activity |Share| etc...
+-----+---------+-----+----
| 1 | 1 |1 |
+-----+---------+-----+---
| 2 | 1 | 2 |
+-----+---------+-----+---
Activity is foreign key to Activity table.
I want to get Id's 1 and 2
Simplified SQL
first of all let me simplify that query so it gives the same result :
SELECT id FROM `activity_shares`
GROUP BY `id`
HAVING COUNT(`activity_id`) > 1
Docrtrine QueryBuilder
If you store the id of the activty in the table like you sql suggests:
You can use the simplified SQL to build a query:
$results =$this->getEntityManager()->createQueryBuilder('c')
->add('select','c.id')
->add('from','MyBundleDataBundle:ActivityShare c')
->groupBy('c.id')
->having('count(c.activity)>1');
->getResult();
If you are using association tables ( Doctrine logic)
here you will have to use join but the count may be tricky
Solution 1
use the associative table like an entitiy ( as i see it you only need the id)
Let's say the table name is activityshare_activity
it will have two fields activity_id and activityshare_id, if you find a way to add a new column id to that table and make it Autoincrement + Primary the rest is easy :
the new entity being called ActivityShareActivity
$results =$this->getEntityManager()->createQueryBuilder('c')
->add('select','c.activityshare_id')
->add('from','MyBundleDataBundle:ActivityShareActivity c')
->groupBy('c.activityshare_id')
->having('count(c.activity_id)>1');
->getResult();
the steps to add the new identification column to make it compatible with doctrine (you need to do this once):
add the column (INT , NOT NULL) don' t put the autoincrement yet
ALTER TABLE tableName ADD id INT NOT NULL
Populate the column using a php loop like for
Modify the column to be autoincrement
ALTER TABLE tableName MODIFY id INT NOT NULL AUTO_INCREMENT
Solution2
The correction to your query
$result=$this->getEntityManager()->createQueryBuilder()
->select('c.id')
->from('MyBundleDataBundle:ActivityShare', 'c')
->innerJoin('c.activity', 'ca')
->groupBy('c.id') //note: it's c.id not ca.id
->having('count(ca.id)>1')
->getResult();
I posted this one last because i am not 100% sure of the output of having+ count but it should word just fine :)
Thanks for your answers.I finally managed to get answer
My Doctrine query is:
$subquery=$this->getEntityManager()->createQueryBuilder('as')
->add('select','a.id')
->add('from','MyBundleDataBundle:ActivityShare as')
->innerJoin('as.activity', 'a')
->groupBy('a.id')
->having('count(a.id)>1');
$query=$this->getEntityManager()->createQueryBuilder('c')
->add('select','c.id')
->add('from','ChowzterDataBundle:ActivityShare c')
->innerJoin('c.activity', 'ca');
$query->andWhere($query->expr()->in('ca.id', $subquery->getDql()))
;
$result = $query->getQuery();
print_r($result->getResult());
And SQL looks like:
SELECT a0_.id AS id0 FROM activity_shares a0_ INNER JOIN activities a1_ ON a0_.activity_id = a1_.id WHERE a1_.id IN (SELECT a2_.id FROM activity_shares a3_ INNER JOIN activities a2_ ON a3_.activity_id = a2_.id GROUP BY a2_.id HAVING count(a2_.id) > 1
