Hi Guys, the statement below is producing the following error;

'Invalid length parameter passed to the LEFT or SUBSTRING function.'

I think I need an ISNULL clause but I'm struggling with the syntax, appreciate it if someone could point me in the right direction.


SELECT
[Contract], WkComm,
SUBSTRING(TuePMWork, 0, CHARINDEX(' ', TuePMWork, 0)),
SUBSTRING(TuePMWork, CHARINDEX(' ', TuePMWork, 0) + 1, LEN(TuePMWork) - CHARINDEX(' ', TuePMWork, 0))
FROM REGULARIZED_AM
WHERE 0 < CHARINDEX(' ', TuePMWork, 0)

it didn't handle situation where SPACE is the last character.

LEN() does not includes the last character. See
select	LEN('abc '), DATALENGTH('abc ')


So changing to DATALENGTH() should fix it
