HI,


I need to create a function that receives a parameter (string) and returns a value if there is a second '*' in the string.

E.g:


Function receives the string:

*4112*21211222

returns number 6


Other e.g


Function receives the string:

*411221211*222

returns number 11


Other e.g


Function receives the string:

411221211222

returns nothing, because there is no second *


Can someone help me with the t-sql to do this?

Thnak you
steveb.

IF LEN(@string) - LEN(REPLACE(@string, '*', '')) >= 2
BEGIN
RETURN LEN(@string) - CHARINDEX('*', REVERSE(@string)) + 1
END

Use this:

Select CHARINDEX('*',@InputString,CHARINDEX('*',@InputString, 1) + 1)



Returns 0 if it doesn't find a second '*'.

edit: too late Sad
