QUERY ODBC Delivers a results set in the same way as a SELECT statement, and must therefore be associated with a cursor via DECLARE and
OPEN, or DECLARE, PREPARE and OPEN.
RESET CONNECTION Closes all open cursors, even if the application has not appropriately closed them.
SELECT DISTINCT (DECLARE CURSOR を使用) Associates the cursor name with the SELECT DISTINCT statement and enables you to retrieve rows of data using the FETCH statement.
SELECT INTO Retrieves one row of results and assigns the values of the items in a specified SELECT list to the host variables specified
in the INTO list.
SET AUTOCOMMIT Enables you to control ODBC AUTOCOMMIT mode at runtime.
