I have a view with a column ADVERTISER_NAME and it hold values like

Staples.com
MacMall Affiliate Advantage Network
Dell Home & Home Office
Buy.com USA and Buy.com CA

I want to define another column that should only get the characters of column ADVERTISER_NAME  until the first occurance of a space
ie if the above value are as follows:
Staples.com
MacMall
Dell
Buy.com

It is similar to the instr function in VB

This code:  select substring(advertiser_name, 1, charindex(' ', Advertiser_Name)) from tablename

 will give you a trailing blank.

Try:  select substring(advertiser_name, 1, charindex(' ', Advertiser_Name) - 1) from tablename

Make sure you're aware that the code you've accepted will leave you with a trailing blank in your data which means you will end up with data that you can't query and find.

It's not reaching.  This user will have data they can't find.  They're expecting to find "Dell" and the value stored in the table is "Dell " with a trailing space.  Those two values won't match in a query.

In my last 25+ years working on data systems this has tripped me up more than once.
