| I'm working in a new environment and I'm not completely familiar with all the tables/fields in the DB. If I've written a query or if I know the fields and tables I plan to use, is there an SP or somethign that I can run to check to see which fields allow nulls?I ask because I will be filtering on many of the fields and I'm trying find a quick way to determine which fileds I need to include the (isnull(??,0) = 0) ectThank you...I appreciate your help |

| You can use sp_help <table_name> to get column info. and look into column nullable to see those columns which allow NULLS.You can also have a look at system table syscolumns for this |
