When all the query parameters are set, you can immediately execute the query in Visual Query Builder.
To execute a query, click the Execute query item of the Navigation bar. You can also use the F9 hot key for the same purpose.
If the query parameters are specified correctly, 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 Result tab.
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 Query Builder window.
