Try the convert hack if it's SQL Server. Make your injection string something like this: convert(int, (convert(varchar, (SELECT TOP 1 name FROM sysobjects WHERE xtype='U')))) You should get back an error message that contains the first name in sysobjects. Again, if it's SQL Server, you can inject procedures. Try injecting sp_makewebtask, which has been discussed on this list twice in the last week I think. You also might want to include in your report that (in theory) they may get a slight performance increase by using type ntext instead of text. The text data type is really there to just include extra information that isn't supposed to be used in applications often (or at least that's my understanding of it.)
