ID: Nexaweb Studio automatically assigns an ID as the statement type, with a numbered suffix incremented by one for each additional statement of this type created. Keep the assigned ID or specify your own. Nexaweb Studio uses this ID to identify this SQL statement in the nexaweb-sql.xml file and to identify the dataRequestDefinition in the nexaweb-data.xml file that references this SQL statement.

ConnectionId: Specifies the ID of the connection to the database which you want to access.

StatementHanlderId: Specifies the ID of the statementHandler to use.

Table: Displays the table selected from the database in the text field, and the entire database schema in the list box from which you can select any table with which to work.

Columns: Displays the columns of the selected table. A check-mark appears in the checkbox beside each column of the table this SQL statement will affect. Click Select All or Deselect All, or the check box beside an individual column to change its selection. To change the order in which data from these columns appear in the UI, click on a column and click Up or Down to move it.

Click Finish.

Nexaweb Studio adds the embeddedServiceRequest to the UI file and displays its ID under the Embedded Service Requests folder in the Data view. Nexaweb Studio also automatically creates a documentDataSource as a target for this embeddedServiceRequest in the UI file and displays its ID in the DataSources folder in the Data view.
