public abstract boolean execute (String sql, int autoGeneratedKeys) throws SQLException

Executes the given SQL statement, which may return multiple results, and signals the driver that any auto-generated keys should be made available for retrieval. The driver will ignore this signal if the SQL statement is not an INSERT statement, or an SQL statement able to return auto-generated keys (the list of such statements is vendor-specific).

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.

The execute method executes an SQL statement and indicates the form of the first result. You must then use the methods getResultSet or getUpdateCount to retrieve the result, and getMoreResults to move to any subsequent result(s).

Note:This method cannot be called on a PreparedStatement or CallableStatement.

Parameters:
sql    any SQL statement
autoGeneratedKeys    a constant indicating whether auto-generated keys should be made available for retrieval using the method getGeneratedKeys; one of the following constants: Statement.RETURN_GENERATED_KEYS or Statement.NO_GENERATED_KEYS

Returns:  true if the first result is a ResultSet object; false if it is an update count or there are no results

Exceptions:
SQLException    if a database access error occurs, this method is called on a closed Statement, the second parameter supplied to this method is not Statement.RETURN_GENERATED_KEYS or Statement.NO_GENERATED_KEYS, the method is called on a PreparedStatement or CallableStatement
SQLFeatureNotSupportedException    if the JDBC driver does not support this method with a constant of Statement.RETURN_GENERATED_KEYS
SQLTimeoutException    when the driver has determined that the timeout value that was specified by the setQueryTimeout method has been exceeded and has at least attempted to cancel the currently running Statement
