Question

I have a transaction which is along the lines of

BEGIN TRANSACTION

INSERT INTO Table2 WITH(TABLOCK)
   SELECT BLAH 
   FROM Table

COMMIT TRANSACTION

This transaction can take up to an hour to complete.

I’d like to run a query a bit like:

SELECT COUNT(*) FROM Table2

at regular intervals on a totally different thread which could report how many rows have been inserted so far.

Is this possible? Is there some way to query for a count of rows which are not committed?

thanks

Answer 1

Add a WITH (NOLOCK) hint to your query.

SELECT COUNT(*) FROM Table2 WITH (NOLOCK);

Take a baseline count before you begin your transaction, then subtract that value from the current number to get the number of newly inserted rows.
