Morning People,
I’m having a little issue with COALESCE causing a stored procedure which is writing data to a table to run excessively. (without the COALESCE it takes 4 minutes and with it it takes 1 hour 30 minutes ish).
I need this staging table’s f_ columns to be clear of NULLs as these will be used for calculus later on in the warehouse which is then being displayed to Cognos reporting studio.
There are 161 columns that require this and I have also tried to do a “CASE WHEN X IS NULL THEN 0 ELSE X” which apparently has a lower impact but still takes an Hour and a half.
Also have added “DEFAULT 0” to the tables build with no joys.
Stored Procedure follows (Apologies in advance for the sheer size of it)
