Hello Brain2000,

You are right mentioning that SQL Server licenses are expensive, and I admit that unzipping on the server is unusual and unexpected.

Like Ool2t5902 mentions, I use the function to...

I just published an article (https://www.sqlservercentral.com/articles/unzipping-word-documents-in-tsql) that explains how to natively unzip in T-SQL

You are right Phil. Images are heavily compressed. I did not express myself correctly as I meant that images are not compressed XML files. You are also right saying I...

I performed my tests on a local SQL Server 2019. I will experiment with all received suggestions during the holidays. Many thanks to all of you and happy holidays!

The following statement runs in 4 seconds and is definitely better:

SELECT
  B.ID,
  D.Value
FROM #Big B
LEFT MERGE JOIN (
  SELECT ID, dbo.GetValueInLanguage('fr', XmlValue) AS Value...

I want to thank you all for your suggestions. This case had me revisit some concepts of SQL Server I usually ignore or avoid.

My procedure declares a lot of variable...

UPDATE SC

  SC.QuickEffectiveDate = SCR.EffectiveDate,
  SC.QuickNominalValueChangeTypeID = SCR.NominalValueChangeTypeID,
  SC.QuickHasRightToVote = SCR.HasRightToVote,

Compatibility level is 150. QUERYTRACEON 9481 has no effect.

Thanks.

homebrew01,

Of course I can fill a temp table and apply the WHERE clause on a "SELECT * FROM #TEMP" statement. This approach has been discussed in forums for ages. But...

Jonathan,

All reports are based on a "body" statement and the WHERE and ORDER BY clause is added according to the user choices. The resulting statement is always executed with OPTION...

Frederico,

I also think that SQL Server is being lousy in this particular case. I would not mind if my "unoptimized" statement would run twice or three times slower but we...

Hi Scott,

like I mentioned earlier, the WHERE clause is added afterwards in my application (so the user can choose to see archived corporations only, active corporations only or both). Therefore,...
