SQL OpenQuery 与使用括号链接的 Oracle 数据库

问题描述

我正在尝试通过 OpenQuery 在 sql Server Management Studio 18 中对链接的 Oracle 数据库运行一个简单的查询。我需要在链接服务器上运行的查询在查询中有括号。

我收到一个错误：

缺少括号的右侧

它在不与 OpenQuery 分开时工作正常，所以我做错了什么？

SELECT * 
FROM OPENQUERY([linked_server],'SELECT 
                    PATIENT_SSN,SPONSOR_SSN,FMPSSN,FMP,dob AS Date_Of_Birth,DATE_ENTERED_INTO_FILE AS Date_Registered,SUBSTRING(NAME FROM 1 FOR LOCATE(",",NAME,1)-1) AS Last_Name,ETHNIC_BACKGROUND_CODE AS Ethnic_Code,SEX AS Gender,MARITAL_STATUS_NAME AS Marital_Status,PHONE AS Phone_Number,STREET_ADDRESS AS Address_Street,CITY AS Address_City,STATE_NAME AS Address_State,ZIP_CODE AS Address_Zip,DOD_ID_ AS DOD_Deers_ID,IEN AS IEN_ID,PATIENT_CATEGORY_NAME AS PAT_CAT,DMIS_ID AS DMIS_ID,PERSON_ID AS Patient_ID,BRANCH_OF_SERVICE_LAST_NAME AS Branch_ID,LAST_UPDATE_TIMESTAMP AS Rec_Updated_Date  
                FROM 
                    my_table')
