Changing Metadata window
The Changing Metadata window is used to trace the errors and edit SQL statements during their compilation. The compilation window appears each time metadata is changed, both when the compilation is successful and when there are compilation errors. To hide this window for successful metadata changes, select the Don't show this window on success option.
This area displays the SQL statement pending to be executed to perform metadata changing. In this area you can view and edit the SQL statement.
In case of a compilation error the Error tab also becomes visible - here you can view the error description returned by the server.
This button starts execution of the statement(s). Click it to commit the current transaction. This button is available only if there were no errors in compilation.
This button cancels the script execution and allows you to return to the previous stage (editor window or DB Explorer).
If necessary, you can copy information to clipboard and save it in a text editor afterwards (the button is only enabled when a compilation error occurs).
If you want this window to appear only in case of an error, uncheck the Confirm metadata changing (Changing Metadata Window) option (checked by default) available within the Confirmations section of the Environment Options dialog.
