How to prevent overwriting the Results Sets when executing a SQL query?
If rerunning a query it overwrites 'Set1' in version 4.5 where in the older version it used to create 'Set2' so you could look back at previous result sets.
If highlighting the code and executing it, then it will create a 'Set 2' but there must be a setting that stops the result sets overwriting without having to highlight the code each time.
Tools | Options | Editor | Tools | "Clear before executing Script"
to have back the old behavior.
