Query console

Last modified: 29 March 2023

Overview

Query consoles are SQL files that are associated with a data source and connected to it via a connection session. In query console you can compose and execute your SQL statements.

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

Database connection session

For each console, a data source connection session is created automatically. You can create new connection sessions and attach your console to existing ones in the console toolbar.

In the following example, the PostgreSQL console is associated with the guest.public schema of a data source and connected to it via the console connection session. You can change the console session to actor or create a new session and attach the console to it.

Read more about managing sessions in Managing connection sessions.

Code editor

The code editor is where you compose your SQL statements using the resolve modes and coding assistance features, and execute them against the associated data source.

Find the code editor toolbar controls in Code editor controls. Read more about the editor in Editor basics.

Resolve modes

In order to run SQL scripts, treat the usages of the database objects as links, and provide you with correct code completion, AppCode must resolve the database objects in your code to a certain context. By default, IDE uses one of the following as a starting point to resolve the database objects to: <schema> selector, or the default database (if none of the above is set).

For more information about resolve modes, refer to Resolve modes.

User parameters

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

SQL statement execution

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.

Code editor controls

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

Transaction Isolation

Select the isolation level for database transactions and the way the transactions are committed.

  • Auto: the current transaction is committed automatically when you submit your local changes to the database server.

  • Manual: the changes submitted to the database server are accumulated in a transaction that can either be committed or rolled back explicitly by means of the Commit (Commit button) or Rollback (Rollback button) buttons on the toolbar.

For more information about database transaction modes and isolation, refer to Submit changes to a database.

Commit

Commit Ctrl+Alt+Shift+Enter

Commit the current transaction. See also, transaction modes and isolation.

Rollback button

Roll Back

Cancel Query

Cancel Running Statements

Ctrl+F2

Terminate execution of the current statement or statements.

Playground

File Resolve Mode

Select the resolve mode to manage the context that database objects in your code are resolved to.

  • Playground: default mode for query consoles. All the database objects are resolved to the same context.

  • Script: default mode for local SQL files. The USE SQL statement (SET search_path TO for PostgreSQL) overrides the default context that the database objects are resolved to.

For more information about the resolve modes, refer to Resolve modes.

Explain Plan

  • Explain Plan: show an execution plan (or explain plan) for the current statement. The result is shown in a mixed tree/table format on a dedicated Plan tab.

    Example of Explain Plan

    To build a diagram of the execution plan, click the Show Visualization button (the Show Visualization button) on the left of the Plan tab, or press Ctrl+Alt+Shift+U.

    To build a flame graph, click the Flame Graph button (the Flame Graph icon).

  • Explain Plan (Raw): show an execution plan (or explain plan) for the current statement. The result is shown in table format. Technically, EXPLAIN <CURRENT_STATEMENT> or similar statement is executed.

    Example of Explain Plan

App actions execute Execute

Ctrl+Enter

Execute the current statement or the sequence of selected statements.

App actions execute Execute to File

Execute the current statement and save results in a text file. Select the output format and specify the file location and name.
