答

这里你没有使用 @ntlg 作为参数，而不是像字符串一样使用它。所以，删除单引号并尝试如下...

Here you have not used the @ntlg as a parameter, rather you have used it like a string. So, remove the single quotes and try like below...

SELECT PROCESS_NAME 
FROM TF_PROCESS_MASTER 
WHERE PROCESS_ID = (SELECT PROCESS_ID 
                    FROM TF_PROJECT_MASTER 
                    WHERE PROJECT_ID = (SELECT PROJECT_ID  
                                        FROM TF_ASSOCIATE_LEVEL 
                                        WHERE SYSTEM_LOGIN_ID = @ntlg)
                    )
