Suppose I write this little query:
When I press play the query is very slow because the Item table has a column that stores large BLOB data, so I want to recover all the columns except that one that contains binary data. With Sql Prompt you can simple put the cursor after the * and press tab
And Sql Prompt will expand the query for you, now I can simply comment the image column
This is really a cool feature I use almost every day.
