I have a target table with the following attributes:
PARTY_ID PK
START_DATE PK
STATUS_CD PK
END_DATE
I have a dynamic lookup which is returning me 1(insert) 2(update) 0 (duplicate) for each row from source table.
What i want is when i get 2(update) to add an END_DATE to the updated row without changing anything else.
For example i have the following row in my target table:
1 12/01/2014 2 NULL
and i get this row from my source table:
1 14/01/2014 6 NULL
What i want is to add ONLY the end date to the target table without anything else. LIKE:
1 12/01/2014 2 14/01/2014
I know how to update the whole row but i dont know how to update only one column.
Schema:
CREATE SET TABLE IND_MAR_STATUS ,NO FALLBACK ,
NO BEFORE JOURNAL,
NO AFTER JOURNAL,
CHECKSUM = DEFAULT,
DEFAULT MERGEBLOCKRATIO
(
INDIVIDUAL_PARTY_ID DECIMAL(18,0) NOT NULL,
INDIV_MARITAL_STAT_START_DTTM DATE FORMAT 'YYYY-MM-DD' NOT NULL,
MARITAL_STATUS_CD VARCHAR(100) CHARACTER SET LATIN NOT CASESPECIFIC NOT NULL,
INDIV_MARITAL_STAT_END_DTTM DATE FORMAT 'YYYY-MM-DD',
ETL_SOURCE_ID DECIMAL(18,0) NOT NULL,
ETL_EXTRACT_SPEC_ID DECIMAL(18,0),
ETL_JOB_RUN_ID DECIMAL(18,0))
PRIMARY INDEX ( INDIVIDUAL_PARTY_ID );
Simply disconnect the target ports you don't want to update (i.e. only PARTY_ID and END_DATE should be connected).

input data
ID CID
1 101,103
1 101
In The Target, I am getting like this, I used listagg function
ID CID
1 101,103,101
But I Want the output like below
ID CID
1 101,103
Use distinct first then use listag. You can refer to below SQL.
SELECT
subqry.ID as id,
listagg(cid,',') within group(order by(id)) as cid
FROM
(select distinct ID, CID from FROM Table1) subqry -- this will deduplicate CIDs first
group by id
Order by 1

I want to limit the number of records in my SQLite table to for example 100 records, and then when I INSERT the 101th record, the first record (the oldest) be removed from the table. In other word, I want to prevent the table from growing more than 100 records and always have the last 100 records. Is there any setting or query with SQLite or should I handle it manually?
thanks in advance
You can do it with a trigger.
Say that your table is this:
CREATE TABLE tablename (
id INTEGER PRIMARY KEY,
name TEXT,
inserted_at TEXT DEFAULT (strftime('%Y-%m-%d %H:%M:%f', 'now'))
);
In the column inserted_at you will have the timestamp of the insertion of each row.
This is not necessary if you declared the column id as:
id INTEGER PRIMARY KEY AUTOINCREMENT
because in this case you could identify the 1st inserted row by the minimum value of the id.
Now create this trigger:
CREATE TRIGGER keep_100_rows AFTER INSERT ON tablename
WHEN (SELECT COUNT(*) FROM tablename) > 100
BEGIN
DELETE FROM tablename
WHERE id = (SELECT id FROM tablename ORDER BY inserted_at, id LIMIT 1);
-- or if you define id as AUTOINCREMENT
-- WHERE id = (SELECT MIN(id) FROM tablename);
END;
END;
Every time that you insert a new row, the trigger will check if the table has more than 100 rows and if it does it will delete the 1st inserted row.
See the demo (for max 3 rows).
It's probably extremely simple but I can't find an answer. I have created a new column and I would like to use the DAX syntax to fill the column with hardcoded values.
I can write this: Column = 10 and I will get a column of 10s but let's say my table has 3 rows and I would like to insert a column with [10, 17, 155]. How can I do that?
Try using DATATABLE function
Table = DATATABLE("Column Name",INTEGER,{{10},{17},{155}})
You can also put more columns with their own data if you want to, check this
https://learn.microsoft.com/en-us/dax/datatable-function
Assuming your table has a primary key column, say, ID, you could create a new table with just the column you want to manually input.
ID Value
---------
1 10
2 17
3 155
You can create this table either through the Enter Data button or create it using the DAX DATATABLE function as #Deltapimol suggests.
Once you have this table you can create a relationship to your existing table in the data model at which point you can either use this new table in your report to get the values you need or if you really need them in the existing table for some reason, you can pull them over using the RELATED function in a calculated column.
Table1 = GENERATESERIES(1, 3)
Table2 = DATATABLE(
"ID", INTEGER,
"Value" INTEGER,
{{1, 10},{2, 17},{3, 155}}
)
Now you can create a relationship from Table1 to Table2[ID] and then define a calculated column on Table1 as follows:
ValueFromTable2 = RELATED(Table2[Value])
If you don't want to create a relationship, then you could use the LOOKUPVALUE function instead in a calculated column on Table11.
I am trying to write a SQL script to set the column values with incremental values based on the values of the id of the previous column. If the Job Id column is the same I would like the Employee column to be populated with incremental values.
I have this so far, but I'm not sure how to group it by JobID and reset the counter if they JobID changes:
DECLARE #employee INT
SET #employee = 0
UPDATE dbo.JobEmployees
SET Employees= #employees, #employees = #employees + 1 where Employees is null
Have a question on Informatica powercenter. We have a target column END_DATE in oracle as date which is populated from a different column. I put an expression transformation and used an IF condition.
IIF(Status='Expired',Currentdate,'12/31/9999')
Basically, if status column has a value 'Expired' it will update END_DATE column as current date ELSE it will put an infinite date such as '12/31/9999'.
Thanks for your help.
