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.

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

In (Som, Ni, Yak)

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

Time is always against us
