RE: Cannot Disable Constraints

An error code with text and constraint name would be helpful. There are different types of constraints which can be violated...  

Also if you trace your session (with binds) when trying to truncate the tables you could get a step closer to the root cause...

Subject: Cannot Disable Constraints

We are having a problem with one of our development databases and have been working on this thing since 8 this morning. We are trying to refresh code tables, which we do all the time, and are getting constraint violation errors. I can't think of anything that has changed on this database.

We spin through the schema, disable constraints on the code tables, truncate the tables, import new code values, and reenable the constraints.

After we disable the constraints we find that we cannot truncate about ten tables and get a constraint violation error. All the constraints appear to be disabled. I cannot figure this out. We have to move ahead and are going to drop the whole schema and reimport the whole thing. What could cause this problem? I know we are missing something but I'm not sure what. We are out of ideas for now.
