如何替换特定单词

CREATE TABLE TESTDE(
Query VARCHAR(150)
);

INSERT INTO TESTDE VALUES ('SELECT EmployeeName FROM EmployeeTable WHERE FirstName = ''Asim'' AND LastName = ''Asghar'' AND EducationLevel = ''School''');


SELECT * FROM TESTDE
SELECT REPLACE(Query, '=', '<>') FROM TESTDE 

我有这个表和一个查询存储在其中。我只想用保存的查询中的某个词替换特定的词。 = 具有 <> EducationLevel . 我有疑问,但它取代了所有 具有 <> .
