SQL statements can be selected from the query capture database (QCD). Use this option if the execution plans are already available in the QCD.

The Query ID and the Query Tag fields are optional. If no values are entered in these fields, all the statements in the QCD are displayed when you click the Browse button.

Query IDs can be added as individual queries separated by comma(s). For example: 1, 2, 3. Use hyphens to separate queries in a range. For example: 5-10. Commas and hyphens can be used together. For example: 1, 2, 3, 5-10.

The Query Tag field is used to retrieve statements from the QCD. The field also accepts wild card characters. Using a percentage sign (%) in this field, loads all the queries from the specified database.
