  • Hi FireStorm2012,

    Could you please make a more detailed description? I'm not quite clear about which situation you have described. Or you could explain the functional description based on the sample table data.

    Best Regards,

  • If you mean that in one transaction you insert new rows into one table (call it TABLEA) and then insert rows into another table (call it TABLEB) and TABLEB has a trigger then is there a system provided way for the trigger on TABLEB to show the rows inserted in TABLEA?  If so, the answer is no.

    If you give us a description of what you are trying to do, the release of SQL Server you are running, sample tables (as CREATE TABLE statement(s)) sample data (as INSERT statement(s)),  and any other info you think we need and show us the result you would want from your process, we may well be able to provide suggestions on how you can accomplish what you want.

  • Sorry not sure on what you're asking here


    new values for inserted records in a transaction from a trigger on a different table 

    do you mean from one table's trigger you want to get the newly inserted values within another table? If yes, its possible as long as you've some columns in the other table like audit trail columns (datemodified,datecreated etc) or you've a sequence based unique id column (mostly PK based on IDENTITY or SEQUENCE). If none of these exists, then its difficult to find the deltas (changes) done by current transaction. However you can capture this in a different table at the same time when you do the insertion if you want. For that you would need to create a table with fields to be captured and use OUTPUT clause in the insert to populate it with the new rows. This table can then be accessed with the trigger for the second table to get new rows

    so it will look like

    BEGIN TRAN InsertOps
    TRUNCATE TABLE NewInsertedData_Table1
    INSERT INTO Table1 (col1,col2,...)
    OUTPUT INSERTED.col1,INSERTED.col2... INTO NewInsertedData_Table1
    INSERT Table2
    COMMIT TRAN InsertOps
    --trigger code
    CREATE TRIGGER <TriggerName>
    ON table2 
    --this will give you the newly inserted rows from table 1
    SELECT *
    FROM NewInsertedData_Table1
