I'm new to visual studio 2008 and sql, little under 2 weeks now. Was hoping someone can help clean up my code. This is a large database and can pull back 6000+ pages. This code works with smaller call backs but on the larger ones hangs.

ORDER BY address_master.id_num,
     vRTCAttStatusDaily.startdate,
     vRTCAttStatusDaily.clean_crs_cde

Any tips would be appreciated.


Ok, it turns out the code written for vrtcattstatusdaily called on itself basically twice. Not much I could do about that, but removing faculty_table_load from the query made it work properly. It now can pull 289k rows in roughly 1.4 mins. Thanks Biggs
