Hi, we have a lot of developers writing a lot of SQL scripts against a lot of different databases. These scripts usually consists of mixed DDL (e.g. change a column definition) and DML (e.g. adding new master data). Since our applications are constantly under development we'd like to add these scripts to our continuous integration environment. For that it would be great to have a feature that checks the script against a given database without actually executing it. It should not only check the SQL syntax but also if all mentioned tables, columns etc. exists in the given database. It is not possible to use transactions for that since DDL is (currently) not transactional. I'm thinking of something like this: SET DISABLE_EXECUTION="TRUE"; -- here come the sql statements SET DISABLE_EXECUTION="FALSE"; I've tried to write such a check with an external tool but as it turned out this is virtually impossible and has a lot of loopholes. Do you think it would be possible to implement something like this in the server? Thanks, Raphael
