Use CHARINDEX and SUBSTRING functions...

Hi Bobby,

You can do this using the String functions in T-SQL, specifically SUBSTRING and CHARINDEX. There are some links below to msdn that will get you started.

If you can provide some readily-consumable sample data, someone will be more likely to put together a query for you.

It's only one sample - I expect you will be posting back shortly

DROP TABLE #TEMP

CREATE TABLE #TEMP ([STR] VARCHAR(200))

INSERT INTO #TEMP VALUES('Forwarded to Approver - SantosM ::: Comment carried forward: ')

SELECT

*,

SUBSTRING([STR], x1.p1, x2.p2-x1.p1)

FROM #TEMP

CROSS APPLY (SELECT p1 = 1+CHARINDEX('-',[STR])) x1

CROSS APPLY (SELECT p2 = CHARINDEX(':',[STR],x1.p1)) x2
