Example 1 with QueryFunction

use of com.servoy.j2db.query.QueryFunction in project servoy-client by Servoy.

the class QBResult method getColumns.

/**
 * returns an array with all the columns that will be in the select of this query.
 * can return empty array. Then the system will auto append the pk when this query is used.
 * @sample
 * var columns = query.result.getColumns();
 *
 * @return An array of QBColumn thats in the select of this query.
