SQL Trigger to Call a Stored Procedure with inserted value as parameter

Question

I would like to monitor a table for inserts and call a stored procedure with the value which has been inserted.

Monitored Table (BatchDetails) will have the following columns BatchID,BatchStartTime,BatchEndTime

Stored Procedure will use the latest BatchID which has been inserted

Note: There will always be only one row inserted at a time.

I have been looking at this link but seem that there is lot going on ie, several tables. Is there a simple way of doing this?

Call stored proc from after insert trigger

Answer 1

You can user a trigger like this:

CREATE TRIGGER TR_Monitor_BatchDetails_Inserts 
    ON BatchDetails
AFTER INSERT
AS 
BEGIN 
    DECLARE @BatchId INT
    SELECT TOP 1 @BatchId = BatchId
    FROM    INSERTED
    ORDER BY [PK_ColumnHere/Date/OtherOrderingColumn] DESC

    EXEC    SomeStoredProc @BatchId
END

But there are a few flaws with it:

1 - there CAN be more rows in INSERTED (rows that are being inserted) and this wont handle all of them

2 - you may want to call your procedure from where the inserts are being made into BatchDetails table. Maybe have a proc that does the inserts, and add there the call to this your procedure. That will be a better way to approach this.

Hope it makes sense

Answer 2

Elaborating a bit on previous answer and considering more than 1 inserted row you could try something like this:

CREATE TRIGGER TR_Monitor_BatchDetails_Inserts 
    ON BatchDetails
AFTER INSERT
AS 
BEGIN 
    DECLARE @BatchId INT
    Declare bcursor cursor local for
    SELECT BatchId FROM INSERTED ORDER BY [PK_ColumnHere/Date/OtherOrderingColumn] DESC
    open bcursor
    fetch next from bcursor into @BatchId
    while @@FETCH_STATUS = 0 begin
        EXEC    SomeStoredProc @BatchId
        fetch next from bcursor into @BatchId
    end
    close bcursor
    deallocate bcursor
END
