Example: Using SQLResultSetTablePane

/////////////////////////////////////////////////////////////////////////
//
// SQLResultSetTablePane example.  This program presents the contents of
// a table in a table pane.  There is a SQLStatementDocument which allows
// the user to type in any SQL statement.  In addition, there is a button
// which allows the user to delete all rows of the table.
//
// Command syntax:
//    SQLResultSetTablePaneExample  system  table
//
// This source is an example of IBM Toolbox for Java "SQLQueryBuilderPane",
// "SQLResultSetFormPane", and "SQLStatementButton".
