/**
 * TSqlMapStatement class corresponds to <statement> element.
 *
 * Mapped Statements can hold any SQL statement and can use Parameter Maps
 * and Result Maps for input and output.
 *
 * The <statement> element is a general "catch all" element that can be used
 * for any type of SQL statement. Generally it is a good idea to use one of the
 * more specific statement-type elements. The more specific elements provided
 * better error-checking and even more functionality. (For example, the insert
 * statement can return a database-generated key.)
