/**
 * An interface used to call <i>Stored Procedures</i>.
 * <p>
 * The JDBC API provides an SQL escape syntax allowing <i>Stored Procedures</i>
 * to be called in a standard way for all databases. The JDBC escape syntax has
 * two forms. One form includes a result parameter. The second form does not
 * include a result parameter. Where the result parameter is used, it must be
 * declared as an {@code OUT} parameter. Other parameters can be declared as
 * {@code IN}, {@code OUT}, or {@code INOUT}. Parameters are referenced either by
 * name or by a numerical index starting at 1.
 * <p>
 * The correct syntax is:
 * <dd>
 * <dl>
 * { ?= call &lt;procedurename&gt; [( [parameter1,parameter2,...] )] }
 * </dl>
 * <dl>
 * { call &lt;procedurename&gt; [( [parameter1,parameter2,...] )] }
 * </dl>
 * </code></dd>
 * {@code IN} parameters are set before calling the procedure,
 * using the setter methods which are inherited from {@code PreparedStatement}.
 * For {@code OUT} parameters, their type must be registered before executing
 * the stored procedure. The values are retrieved using the getter methods
 * defined in the {@code CallableStatement} interface.
 * <p>
 * {@code CallableStatement}s can return one or more {@code ResultSets}. In the
 * event that multiple {@code ResultSets} are returned, they are accessed using
 * the methods inherited from the {@code Statement} interface.
