1 check constraints do *not* occur in user_cons_columns You need to use the search_condition column from user_constraints 2 Please download Toad from www.toadsoft.com run this query in a sql window, you will get a spreadsheet like output. Right click on the output window, export it to csv, and post it here. Alternatively start a schema browser, and export the table definition to a text file.

You query is correct, but I can't imagine why on earth you would have that many check constraints.
