That seems quiet specific, but it actually isn't. Consider this SQL file, that sets a procedure:


    DROP PROCEDURE IF EXISTS `assert`;
    -- Position 1
    DELIMITER $$
    -- Position 2
    CREATE PROCEDURE `assert`(IN `asserting` TINYINT(1) UNSIGNED, IN `code` INT UNSIGNED)
    	LANGUAGE SQL
    	DETERMINISTIC
    	CONTAINS SQL
    	SQL SECURITY INVOKER
    BEGIN
        -- Position 3
    	IF NOT(`asserting`) THEN
    		CALL throw('UserException', `code`, '{}');
    	END IF;
    	-- Position 4
    END$$
    -- Position 5
    DELIMITER ;
    -- Position 6

There, if you type "SELECT * FROM {Ctrl+Sp}" at each position, you have the following results:
Positon 1 → OK, works (suggests the tables name)
Positon 2 → OK, same
Positon 3 → OK, same
Positon 4 → FAILS, suggests the basic SQL keywords (CREATE, DROP, etc)
Positon 5 → OK, same
Positon 6 → OK, same

So in that very precise place "4", the autocompletion seems to fail.
