MySQL連接/ C++聲明變量

Question

我想創建一個4插入一個存儲過程，我有這樣的代碼

Driver * driver = get_driver_instance(); 
    auto_ptr<Connection> vCon(driver->connect(getHost(), getUser(), getPassword())); 
    vCon->setSchema(getDB()); 
    auto_ptr<Statement> vStmt(vCon->createStatement()); 

    vStmt->execute("DROP PROCEDURE IF EXISTS add"); 
    vStmt->execute("CREATE PROCEDURE add() begin DECLARE vEvId int DEFAULT 0; DECLARE vAdrEvId int DEFAULT 0; insert into adrEv(den) values('test'); select last_insert_id() into vAdrEvId; insert into ev(den,adrEvId) values('test',vAdrEvId); select last_insert_id() into vEvId; ... other insert ... END;"); 

    vStmt->execute("CALL add()"); 
    vStmt->execute("DROP PROCEDURE IF EXISTS add"); 

whay我得到這個錯誤# ERR: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'add' at line 1 (MySQL error code: 1064, SQLState: 42000)

ADD是MySQL的一個reserved word。嘗試使用更具體/描述性的過程名稱。
