Select Mid() in MS SQL Server 7

I am trying to use the select mid command in SQL Server 7, only to learn that it's not supported--Does anyone know how to do this? Here's what I'm trying to do.

I want to break a 10-digit phone number into area code, prefix, and last four digits. In Oracle SQL I would type:

select left(PhoneNumber,3) as 'AreaCode, mid(PhoneNumber,4,3) as 'Prefix', right(PhoneNumber,4) as 'Last4Digits'.

However when I try to do this in SQL Server Query Analyzer, I receive a notice that 'mid' is not a function.

Help! Thanks in advance.

 

Try Mid$

 

That didn't work either. :-/

 

You might play with this. Note that it's pulling bytes, so look out for unicode.

If you are in fact working with binary data, you should read this bug report, too, though it does not mention mid--does mention the other string functions, tho. Have you searched SQL Server help for string functions?
