Creating a DELETE Statement

Use SQL Query Builder to create a DELETE statement to remove data from a specified table. By specifying one or more conditions, you can indicate which rows in the database table to delete. If you do not specify any conditions, all rows in the target table are deleted.

Prerequisites 

Connect to the data source through a connection profile.

Note: Some syntactic variations might exist between your database and the SQL syntax that SQL Query Builder supports; consequently, some SQL Query Builder features might not work with your database.
  1. Open a new or an existing SQL file, and be sure to select the connection profile Type, Name, and Database.
  2. In an appropriate place in the editor window, right-click and select Edit in SQL Query Builder.
  3. In the Outline pane, right-click SELECT Statement and select Change Statement Type.
  4. Select DELETE and click OK.
  5. Select the table by right-clicking in the Tables pane and selecting Add Table.
  6. (Optional) Indicate one or more conditions that target specific rows for deletion.
    1. Select a Column.

      Alternately, select define a condition using the Expression Builder wizard.

    2. Select an Operator.
    3. Enter a specific Value, select a column from the drop-down list, or build an expression.
    4. (Optional) Select AND or OR to specify another condition.
  7. (Optional) To run the SQL code, in the SQL Source pane, right-click and select Run SQL.

    View the results in the SQL Results tab.

  8. Click OK to exit SQL Query Builder and to return to the SQL File Editor, where the SQL code displays in the editor window.

    Clicking Cancel results in no changes to the SQL code in the SQL File Editor. You lose any changes you made in SQL Query Builder.
