Sorry, new member didn't know whether I should hit reply or send as new message.
SELECT cscflash_mb.email FROM cscflash_mb LEFT JOIN csc_teammembers USING (email) WHERE csc_teammembers.tes_email IS NULL; MySQL said: Unknown column 'csc_teammembers.email' in 'on clause' What ON clause? Note: in the above I changed the original suggestion: SELECT cscflash_mb.email FROM cscflash_mb LEFT JOIN csc_teammembers USING (email) WHERE csc_teammembers.email IS NULL; TO read as above...as there is not csc_teammembers.email column.
