SQL Server: any equivalent of strpos()?

Question

I'm dealing with an annoying database where one field contains what really should be stored two separate fields. So the column is stored something like "The first string~@~The second string", where "~@~" is the delimiter. (Again, I didn't design this, I'm just trying to fix it.)

I want a query to move this into two columns, that would look something like this:

UPDATE UserAttributes
SET str1 = SUBSTRING(Data, 1, STRPOS(Data, '~@~')),
    str2 = SUBSTRING(Data, STRPOS(Data, '~@~')+3, LEN(Data)-(STRPOS(Data, '~@~')+3))

But I can't find that any equivalent to strpos exists.

Answer 1

User charindex:

Select CHARINDEX ('S','MICROSOFT SQL SERVER 2000')
Result: 6
