Procedure

  1. On the top menu bar, choose SQL Operations > SQL Window. On the displayed page, select a database from the navigation pane.
  2. Enter SQL statements in the SQL window and click Execute SQL.

    • To protect query result sets from being displayed as garbled characters caused by UTF-8, the default encoding format, select an encoding format as needed.
    • To execute multiple SQL statements at a time, separate them using semicolons (;).
    • To execute some of the SQL statements, select the statements before executing them.
    • To execute all the SQL statements, do not select any SQL statements or select all of them.

      • If the result set involves a view, you cannot edit the data.
      • If the type of the result set is metadata, the data cannot be edited or displayed on multiple pages.
      • If the result set involves multiple tables, you cannot edit the data.
      • If the result set involves only one table and does not include all the primary key columns of the table or no primary key is found, you cannot edit the data.
      • Virtual tables (for example, tables generated during SQL execution) cannot be edited.
