So I'm having an issue with our Card Control system. Long story short, ID badges are swiped to gain access to certain doors throughout the building. The access levels for each user is stored in a SQL Database. Upon loading the admin console to this system "Error Converting Data Type Varchar to Bigint" pops up over and over again for about twenty minutes, then the system freezes and needs to be restarted. While in SQL Management Studio though, I don't receive any errors. Is there a way to create a query of somesorts that searches through the thousands of rows of information with the two hundred tables in the Database so I don't have to? The error does no9t reference what table, what column, anything. It just says there's an error, then the system freezes.
It's late, my eyes hurt, I want sleep.

Can anyone help? Thanks.
