How to run update queries saved in a permanent table?
DECLARE @Query1 nvarchar(max) = N'';

SELECT @Query1 += Query + N';' FROM dbo.PermaTable1;

PRINT @Query1; -- to see the first 8,192 characters

-- EXEC sys.sp_executesql @Query1; -- uncomment this when you trust it


But I have questions. Shouldn't those update queries have where clauses? Otherwise each one is going to overwrite all rows and basically undo all the updates that came before it. Also are these update commands really stored in the same table they affect?
