To Use the Visual SQL Query Builder to Build a Query: Example 3

Note: The Visual SQL Data Browser only displays the data. Make edits to the database in the Forms mode.

Note: To edit any of the Where clauses, click the clause in the Where Fields list box. Dynamically change the field, operator, value, and AND/OR clause members as you would normally do when building an SQL statement. Clicking Apply conforms the SQL Select Statement to your changes in the Where Fields dialog. You can also delete the clause by clicking Clear.

Note: If your selection in Available Fields is a character type, your entry in the Value text field (for example, 100) is displayed with single quotes around it in the Value column of the Where Fields list box (is displayed as '100').
