Select from 2 tables?  SQL 2005

I need to perform this query.

Select firstname, email from dbo.providers where (Active = '1')  AND   (BIO from dbo.BIOS = '' where dbo.providers ID = dbo.bios ID)  

The column ID in dbo.providers is an identity column and also is identical in dbo.BIOS.  

I basically want to select the firstname and email from the providers table where their bio is blank in the bios table, and where Active = '1' in the providers table.

I hope this made sense.

Try this.
Select firstname, email from dbo.providers A
       LEFT JOIN dbo.BIOS B on A. providers ID  
       where A.Active = '1'  AND B.BIOS = ''

aanvik, doing a left join won't help you at all in the query since you're setting criteria on the BIOS table in your where clause.

Select firstname, email from dbo.providers A
       INNER JOIN dbo.BIOS B on A. providers ID  
       where A.Active = '1'  AND ISNULL(B.BIOS, '') = ''

sorry, that was all messed up.

Select firstname, email from dbo.providers A
       INNER JOIN dbo.BIOS B on A.ID= B.ID
       where A.Active = '1'  AND ISNULL(B.BIOS, '') = ''
