/**
 * Executes a series of SQL statements on a database using PDO.
 *
 * <p>Statements can
 * either be read in from a text file using the <i>src</i> attribute or from
 * between the enclosing SQL tags.</p>
 *
 * <p>Multiple statements can be provided, separated by semicolons (or the
 * defined <i>delimiter</i>). Individual lines within the statements can be
 * commented using either --, // or REM at the start of the line.</p>
 *
 * <p>The <i>autocommit</i> attribute specifies whether auto-commit should be
 * turned on or off whilst executing the statements. If auto-commit is turned
 * on each statement will be executed and committed. If it is turned off the
 * statements will all be executed as one transaction.</p>
 *
 * <p>The <i>onerror</i> attribute specifies how to proceed when an error occurs
 * during the execution of one of the statements.
 * The possible values are: <b>continue</b> execution, only show the error;
 * <b>stop</b> execution and commit transaction;
 * and <b>abort</b> execution and transaction and fail task.</p>
 *
 * This task can also be used as a Condition.
