When all the query parameters are set, you can immediately execute the query in SQL Editor.
If the SQL syntax is correct, the query is executed and, in case the query statement is supposed to return data (e.g. as SELECT statement), the returned dataset appears within the Results tab. The position of the tab depends on the Results on Edit tab / Results on separate tab selection in the Navigation bar.
If SQL syntax of the query contains any errors, the query execution is stopped and the corresponding error message is displayed in the status bar area at the bottom of the editor window.
