The Messages tab of the Options dialog in Interactive SQL has the following components:
Measure execution time for SQL statements Select this option if you want Interactive SQL to measure the time it takes for a statement to execute. The time appears on the Messages tab. By default, this option is selected.
Show separate Messages pane Select this option if you want information from the database server, such as execution time, to appear in the Messages pane between the SQL Statements and Results panes rather than on the Messages tab in the Results pane. By default, database server information appears on the Messages tab in the Results pane.
Default number of lines in Messages pane Type the number of lines you want returned in the Messages pane. The default number is 7. This value is used only if Show Separate Messages Pane is selected. If you select Show Separate Messages Pane, the number is also the height (in lines) of the Messages pane.
