文档解释
ORA-41645: duplicate tag “string” in rule condition
Cause: An attempt was made to specify the same XML tag in more than one positions within a single rule condition.
Action: Remove the duplicate reference to the tag and try again.
ORA-41645 错误表明,在规则条件语句中存在重复标签。
根据Oracle官方文档,ORA-41645 是 Oracle 中应用程序错误。发生该错误时,Oracle 遇到重复标签(”string”),无法解析规则条件。
常见案例
1.在 SELECT 中使用重复标签:SELECT employee_id,LOCATION ‘location1’,LOCATION ‘location2’ FROM EMPLOYEES;
2.执行有效性检查时使用多余标签:VALIDATE CONSTRAINT emp_loc CHECK (location=’location1′ AND location=’location2′
3.在 WITH 条件中存在重复标签:SELECT employee_id FROM EMPLOYEES WHERE EMPLOYEE_ID IN (WITH location1 AS (SELECT EMPLOYEE_ID FROM EMPLOYEES WHERE LOCATION’location1′),location2 AS (SELECT EMPLOYEE_ID FROM EMPLOYEES WHERE LOCATION’location1′) SELECT EMPLOYEE_ID FROM location1,location2);
一般处理方法及步骤
1.确认重复使用的标签是否完全一致。
2.更正标签,以避免重复使用。
3.确保编写的查询语句逻辑正确。
4.重新检查语句,确保语法没有问题。
5.重新尝试执行语句。
