Hi all i have the following code:
tx = session.beginTransaction();
Query query = session.createQuery("UPDATE com.nisid.entities.Payment set amount=:amount,paymentMethod=:method,paymentExpire=:expireDate"
+ "Where paymentId=:payid,actionId=:actionid");
query.setParameter("amount", amount);
query.setParameter("method", method);
query.setParameter("expireDate", expireDate);
query.setParameter("payid", projectId);
query.setParameter("actionid", actionId);
int resutl=query.executeUpdate();
Trying to do an update using HQL but i am getting error: galArgumentException: node to traverse cannot be null!
my table in the DB is called Payment and it has A COMPOSITE KEY ( projectId,actionId)
Could you please help me further???
The concept is that i have a JSP page which retrieves and displayes the results from DB retrieving info from Project Table, Payment Table and Action Table. Project has many to many relationship with Action and i am using Payment Table as the intermetiary table which holds the 2 FK of the other table.
You missed space before where, and replace , to and after where.
Query query = session.createQuery("UPDATE com.nisid.entities.Payment set amount=:amount,paymentMethod=:method,paymentExpire=:expireDate"
+ " Where paymentId=:payid and actionId=:actionid");

I have an API which reads from two main tables Table A and Table B.
Table A has a column which acts as foreign key to Table B entries.
Now inside api flow, I have a method which runs below logic.
Raw SQL -> Joining table A with some other tables and fetching entries which has an active status in Table A.
From result of previous query we take the values from Table A column and fetch related rows from Table B using Django Models.
It is like
query = "Select * from A where status = 1" #Very simplified query just for example
cursor = db.connection.cursor()
cursor.execute(query)
results = cursor.fetchAll()
list_of_values = get_values_for_table_B(results)
b_records = list(B.objects.filter(values__in=list_of_values))
Now there is a background process which will enter or update new data in Table A and Table B. That process is doing everything using models and utilizing
with transaction.atomic():
do_update_entries()
However, the update is not just updating old row. It is like deleting old row and deleting related rows in Table B and then new rows are added to both tables.
Now the problem is if I run api and background job separately then everything is good, but when both are ran simultaneously then for many api calls the second query of Table B fails to get any data because the transaction executed in below manner:
Table A RAW Transaction executes and read old data
Background Job runs in a single txn and delete old data and enter new data. Having different foreign key values that relates it to Table B.
Table B Models read query executes which refers to values already deleted by previous txn, hence no records
So, for reading everything in a single txn I have tried below options
with transaction.atomic():
# Raw SQL for Table A
# Models query for Table B
This didn't worked and I am still getting same issue.
I tried another way around
transaction.set_autocommit(False)
Raw SQl for Table A
Models query for Table B
transaction.commit()
transaction.set_autocommit(True)
But this didn't work either. How can I read both queries in a single transaction so background job updates should not affect this read process.
I am using Postman and Netsuite's SuiteQL to query some tables. I would like to write two queries. One is to return all items (fulfillment items) for a given sales order. Two is to return all sales orders that contain a given item. I am not sure what tables to use.
The sales order I can return from something like this.
"q": "SELECT * FROM transaction WHERE Type = 'SalesOrd' and id = '12345'"
The item I can get from this.
"q": "SELECT * FROM item WHERE id = 1122"
I can join transactions and transactionline for the sale order, but no items.
"q": "SELECT * from transactionline tl join transaction t on tl.transaction = t.id where t.id in ('12345')"
The best reference I have found is the Analytics Browser, https://system.netsuite.com/help/helpcenter/en_US/srbrowser/Browser2021_1/analytics/record/transaction.html, but it does not show relationships like an ERD diagram.
What tables do I need to join to say, given this item id 1122, return me all sales orders (transactions) that have this item?
You are looking for TransactionLine.item. That will allow you to query transaction lines whose item is whatever internal id you specify.
{
"q": "SELECT Transaction.ID FROM Transaction INNER JOIN TransactionLine ON TransactionLine.Transaction = Transaction.ID WHERE type = 'SalesOrd' AND TransactionLine.item = 1122"
}
If you are serious about getting all available tables to query take a look at the metadata catalog. It's not technically meant to be used for learning SuiteQL (supposed to make the normal API Calls easier to navigate), but I've found the catalog endpoints are the same as the SuiteQL tables for the most part.
https://{{YOUR_ACCOUNT_ID}}.suitetalk.api.netsuite.com/services/rest/record/v1/metadata-catalog/
Headers:
Accept application/schema+json
You can review all the available records, fields and joins in the Record Catalog page (Customization > Record Catalog).
Hi all how I have a product, order and product order(bridge entity) table.
Im building a cart based order system c++ program where when user make a new order ,it will have product id listed on a list and every product will have its own orderID. Im kinda confused on the sql side on how to insert data that have brige entity and join them together
The table have the following attrbs
Table product
ProductID
Table Order1
OrderID,
Totalprice,
description,
agentid
Table product_order(bridge entity)
ProductID,
OrderID,
quantity
I'm planning to insert data only 1 time simultaneously inserting into the other table as well . Its possible to use join + insert?
I got lots of example to append/overwrite table in sql from AZ Databricks Notebook. But no single way to directly update, insert data using query or otherway.
ex. I want to update all row where (identity column)ID = 1143, so steps which I need to taken care are
val srMaster = "(SELECT ID, userid,statusid,bloburl,changedby FROM SRMaster WHERE ID = 1143) srMaster"
val srMasterTable = spark.read.jdbc(url=jdbcUrl, table=srMaster,
properties=connectionProperties)
srMasterTable.createOrReplaceTempView("srMasterTable")
val srMasterTableUpdated = spark.sql("SELECT userid,statusid,bloburl,140 AS changedby FROM srMasterTable")
import org.apache.spark.sql.SaveMode
srMasterTableUpdated.write.mode(SaveMode.Overwrite)
.jdbc(jdbcUrl, "[dbo].[SRMaster]", connectionProperties)
Is there any other sufficient way to achieve the same.
Note : Above code is also not working as SQLServerException: Could not drop object 'dbo.SRMaster' because it is referenced by a FOREIGN KEY constraint. , so it look like it drop table and recreate...not at all the solution.
You can use insert using a FROM statement.
Example: update values from another table in this table where a column matches.
INSERT INTO srMaster
FROM srMasterTable SELECT userid,statusid,bloburl,140 WHERE ID = 1143;
or
insert new values to rows where one of the existing column value matches
UPDATE srMaster SET userid = 1, statusid = 2, bloburl = 'https://url', changedby ='user' WHERE ID = '1143'
or just insert multiple values
INSERT INTO srMaster VALUES
(1, 10, 'https://url1','user1'),
(2, 11, 'https://url2','user2');
In SQL Server, you cannot drop a table if it is referenced by a FOREIGN KEY constraint. You have to either drop the child tables before removing the parent table, or remove foreign key constraints.
For a parent table, you can use the below query to get foreign key constraint names and the referencing table names:
SELECT name AS 'Foreign Key Constraint Name',
OBJECT_SCHEMA_NAME(parent_object_id) + '.' + OBJECT_NAME(parent_object_id) AS 'Child Table'
FROM sys.foreign_keys
WHERE OBJECT_SCHEMA_NAME(referenced_object_id) = 'dbo' AND
OBJECT_NAME(referenced_object_id) = 'PARENT_TABLE'
Then you can alter the child table and drop the constraint by its name using the below statement:
ALTER TABLE dbo.childtable DROP CONSTRAINT FK_NAME;
I have searched for the solution to this problem for a long time, but I haven't got the appropriate method.
Basically All I have is tons of tables, and I want to query value from different tables using raw SQL.
In Django, we need a class representing a table to perform the query, for example:
Routes.objects.raw("SELECT * FROM routes")
In this way, I can only query a table, but what if I want to query different tables based on the user's input?
I'm new to Django, back in ASP.NET we can simply do the following query:
string query = "SELECT * FROM " + county + " ;";
var bus = _context.Database.SqlQuery<keelung>(query).ToList();
Is this case, I can do the query directly on the database instead of the model class, and I can select the table based on the user's selection.
Is there any method to achieve this with Django?
You can run raw queries in Django like this -
From django.db import connection
cursor = connection.cursor()
table = my_table;
cursor.execute("Select * from " + table)
data = cursor.fetchall()
