Description

Add function `executeStatement` Sesssion and SessionPool, referring to java.sql.Statement#execute(java.lang.String).

 /**
 * Executes the given SQL statement, which may return multiple results.
 * In some (uncommon) situations, a single SQL statement may return
 * multiple result sets and/or update counts.  Normally you can ignore
 * this unless you are (1) executing a stored procedure that you know may
 * return multiple results or (2) you are dynamically executing an
 * unknown SQL string.
 * <p>
 * The <code>execute</code> method executes an SQL statement and indicates the
 * form of the first result.  You must then use the methods
 * <code>getSessionDataSet</code> to retrieve the result.
 * <p>
 * @param sql any SQL statement
 * @return <code>true</code> if the first result is a <code>SessionDataset</code>
 *         object; <code>false</code> if it is an update count or there are
 *         no results
 * @throws IoTDBConnectionException if a database access error occurs.
 * @throws StatementExecutionException when the statement failed.
