Stored functions returning values

The following example shows how to retrieve the return value of a stored function with Oracle® MySQL:

MySQL version 5.0 does not allow you to prepare the

CREATE
FUNCTION

statement; you may need to execute this statement from the mysql command line tool.

MAIN
   DEFINE n INTEGER
   DEFINE c VARCHAR(200)
   DATABASE test1
   EXECUTE IMMEDIATE "create function func1(p1 integer)"
                || " no sql begin"
                || "    return concat( 'Value = ', p1 );"
                || "  end;"
   PREPARE stmt FROM "select func1(?)"
   LET n = 111
   EXECUTE stmt USING n INTO c
   DISPLAY c
END MAIN
