Query console

Overview

Query consoles are SQL files that are associated with a data source.

For example, if you open a query console for MySQL, a connection session to the MySQL data source is automatically created. When you open an SQL file from your hard drive, you need to specify the connection session first.

In the following example, the MySQL console is attached to the production session. You can change the production session to testing or create a new session. Read more about managing sessions in Managing connection sessions.

Console file

The input pane of a query console opens as a separate editor tab. The input pane is where you compose your SQL statements.

When you execute a statement, the Services tool window opens. The Services tool window displays available connection sessions, Output and Result tabs. For more information about the Services tool windows, see Services tool window.

If the executed statement retrieves data (for example, SELECT), results are displayed in the Result tab that has a title of a qualified table name. For more information about creating custom titles for result tabs, see Use custom titles for tabs with results.

Use custom titles for tabs with results

If the executed statement does not retrieve data, results are displayed in the Output tab.

Results in the Output tab

Before execution of a parametrized statement, you see the Parameters window where you can specify values for the parameters.

Run a statement with parameters

Input pane

Use the input pane to compose and execute your SQL statements as well as to perform other associated tasks.
