Configure connection

When you create a data source, Aqua connects to a database automatically to receive database objects. Then the connection closes. Names of data sources that interact with a database are shown in the Database tool window with a little green circle.

If you want to close a database connection, select a data source and click the Deactivate button (the Deactivate button) on the toolbar. Alternatively, select a data source and press Ctrl+F2.

    <type>:[-]<pattern>, where:

    • <type> might be an aggregate, collation, event, fdw, ftable, mview, operator, package, role, routine, sequence, synonym, table, user, view, vtable.

    • <pattern> is a regular expression. To exclude an item, prepend with - (minus). For more information about regular expressions, refer to Class Patterns at JavaTM 2 Platform Standard Edition 5.0 API Specification.

Filter databases and schemas

  1. Open data source properties. You can open data source properties by using one of the following options:

    • In the Database tool window ( View | Tool Windows | Database) , click the Data Source Properties icon The Data Source Properties icon.

    • Press Shift+Enter.

  2. On the Data Sources tab, select a data source that you want to modify.

  3. On the Schemas tab, type filtering options in the Schema pattern field.

    • @: the current database or schema.

    • *: every database or schema. You can list schemas after *:.

    Consider the following examples:

    • *:*: all schemas in all databases.

    • @:*: all schemas from the current database

    • @:@: only the current schema

    • *:dbo|@:@|db1:s1,s2,s3: the dbo schema from all databases, the current schema, schemas s1,s2,s3 from the db1 database.

Connection modes

Enable read-only mode for a connection

  1. Open data source properties. You can open data source properties by using one of the following options:

    • In the Database tool window ( View | Tool Windows | Database) , click the Data Source Properties icon The Data Source Properties icon.

    • Press Shift+Enter.

  2. On the Data Sources tab, select a data source that you want to modify.

  3. On the Options tab, select the Read-only checkbox.

    Enable read-only mode for a connection

Single session mode

Single session mode means that the data source and all consoles use one and the same connection. This mode allows you to see the temporary objects in the database tree, or use the same transaction in different query consoles.

When you apply single session mode, you must close all existing opened connections. Aqua displays a notification if you have opened connections. To close opened connections for the selected data source, click Yes. To close opened connections for all modified data sources, click Yes for All.

  1. Open data source properties. You can open data source properties by using one of the following options:

    • In the Database tool window ( View | Tool Windows | Database) , click the Data Source Properties icon The Data Source Properties icon.

    • Press Shift+Enter.

  2. On the Data Sources tab, select a data source that you want to modify.

  3. On the Options tab, select Single session mode.

  4. Click Apply.

    Enable the single session mode

Single database mode

When you connect to a data source, Aqua can retrieve and display you all the databases that the data source has. But in some cases (for example, with certain settings of PgBouncer), you can or are allowed to work only with a certain database. With the Single database mode enabled, you see in the database tree view only the database that you specified in the connection settings, not all the databases that were received from the data source.

Consider using this setting, for PostgreSQL, Azure SQL Database, Greenplum, Amazon Redshift.

  1. Open data source properties. You can open data source properties by using one of the following options:

    • In the Database tool window ( View | Tool Windows | Database) , click the Data Source Properties icon The Data Source Properties icon.

    • Press Shift+Enter.

  2. On the Data Sources tab, select a data source that you want to modify.

  3. On the Options tab, select Single database mode.

  4. Click Apply.

    Enable the single database mode

Transaction mode

A commit ends a transaction and makes all changes available to other users. In Aqua, you can select how you want to commit transactions: automatically or manually.

How changes are committed to a database

The data editor accumulates all the changes that you made. When you press the Submit and Commit button (the Submit button), Aqua sends these changes to a database. In the database, changes are processed according to the selected commit mode:

  • With Tx:Auto, the database itself commits all the changes.

  • With Tx:Manual, changes are stored in a transaction in the database. When you press Submit and Commit (the Submit and Commit button), transactions are committed to the database. When you commit the transaction, the Submit and Commit icon (the Submit and Commit button) disables (grays out). It means that all the transactions have been committed.

If the commit mode is set to Auto, each change of values, rows, or columns is implicitly committed and cannot be rolled back. In the Auto commit mode, Submit and Commit (The Submit and Commit button) and Roll Back (The Rollback button) buttons are disabled and hidden.

If the commit mode is set to Manual, you can explicitly commit or roll back the submitted changes by clicking Submit and Commit (The Commit button) or Roll Back (The Rollback button) buttons. To submit changes to a database, click the Submit button (The Submit button).

The Tx switch can also be used for selecting the isolation level for the transactions.

Change the transaction level

Select the default transaction mode for a data source

  1. Open data source properties. You can open data source properties by using one of the following options:

    • In the Database tool window ( View | Tool Windows | Database) , click the Data Source Properties icon The Data Source Properties icon.
