If there are several SQL statements in the editor then , make sure to separate them using the statement delimiter character (the default to is ";").

In order for the column name completion pop-up to appear, you must first make sure there are table names in the statement.

All table names that has have been listed in the completion pop-up are cached by DbVisualizer to make sure subsequent displays of the pop-up is performed quickly without asking the database. The cache is cleared only when doing a Refresh in the database objects tree or reconnecting the database connection.

The Database and Schema lists above the editor is are used to assist the auto completion feature to limit which tables to list in the pop-up.limit the list of tables in the auto complete pop-up to those in the selected database and/or schema. To include all tables, select the blank entries in these lists. The default selections for the lists can be set in the connection properties, in the SQL Commander category.
