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.
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.
In order to run SQL scripts, treat the usages of the database objects as links, and provide you with correct code completion, DataSpell 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.
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.
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.
If the executed statement does not retrieve data, results are displayed in the Output tab.
Code editor controls
Use the code editor to compose and execute your SQL statements as well as to perform other associated tasks.
