Do SET Statements happen in order?
Multi tool use
0
Since I could not find it out here, do set statements happen in order scripted? Below is query I found. Would I get the same result every time it ran?
DECLARE @Num VARCHAR(10) = '10';
DECLARE @Cleaned VARCHAR(10);
SET @Cleaned = SUBSTRING(@Num, PATINDEX('%[^0]%', @Num+'.'), LEN(@Num));
SET @Cleaned = CASE
WHEN LEN(@Cleaned) > 3
THEN @Cleaned
ELSE RIGHT('00000'+@Cleaned, 3)
END;
-- to be set up
SELECT @Num AS [before]
, @Cleaned AS [After]

That query will always return the same results, every time, until Num value is changed. T-SQL is procedural, so Cleaned will always have the SUBSTRING value first and the CASE value second.
