Hmm, that task sounds like it should be a single INSERT statement, which means SQL should resolve GETDATE() only once.  Therefore it seems as if your trigger is using a...

You don't need a calendar table for this.  Also, note that the Friday check below works under any/all DATEFIRST settings.  DATEFIRST is not something you want to change in your...

SELECT DATEADD(DAY, (@DaysDifference + 6) / 7 * 7, @OriginalFirstStartDate)

The UPDATE "doesn't work" because since reserve is null, it will stay null, even though you think you "added 1 to it".  NULL + 1 = NULL.

If you prefer, you...

SELECT
    Id,

Would you provide the actual T-SQL statement you were attempting to execute?

The fix is:

Select STUFF((Select Distinct + ', '+ CONVERT(varchar(20), A1.date, 105)

Getting rid of NOLOCK will only hurt performance, never help it.  That's not an endorsement of nor objection to NOLOCK in these specific statements, just a general statement of fact. ...

Quote: "We couldn't do much about the database design as it is a vendor specific database."

Understood.  Lol, the only thing potentially worse than a "programmer (non)'designed' table" is a "vendor...

Try below.  Sorry, I don't have time right now to explain the code.

According to your table structure, there is no index on [MULE_BATCH_ID].  This means that SQL has to do a table scan to find the record.
