It's SubString:
Update YourTable set YourField = SubString(YourField,1,CharIndex('-',YourField)-1)

Will your db performance match your db growth?

In Percona’s white paper “Performance at Scale: Keeping Your Database on Its Toes,” we take a high-level approach to what you need to think about when planning for database scalability.

Like i mentioned in my other comment.  I changed CharIndex to Locate and it worked perfectly.  Doing a quick search, I am not 100% sure if CharIndex is supported by mysql.  I did not see it come up in the mysql reference.

In MySQL it's Locate, you are absolutely correct, I was thinking MS SQL :-)

Thanks.
