Executes the given SQL statement, which may return multiple results, and signals the driver that the auto-generated keys indicated in the given array should be made available for retrieval. This array contains the indexes of the columns in the target table that contain the auto-generated keys that should be made available. The driver will ignore the array 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).

Under 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

columnIndexes an array of the indexes of the columns in the inserted row that should be made available for retrieval by a call to the method getGeneratedKeys

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 elements in the int array passed to this method are not valid column indexes, the method is called on a PreparedStatement or CallableStatement

SQLFeatureNotSupportedException     if the JDBC driver does not support this method

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

Since: 1.4

`sql`		any SQL statement
`columnIndexes`		an array of the indexes of the columns in the inserted row that should be made available for retrieval by a call to the method `getGeneratedKeys`

`SQLException`		if a database access error occurs, this method is called on a closed `Statement`, the elements in the `int` array passed to this method are not valid column indexes, the method is called on a `PreparedStatement` or `CallableStatement`
`SQLFeatureNotSupportedException`		if the JDBC driver does not support this method
`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`
