PLS-00525: Within SQL statements, only equality comparisons of objects are allowed without a map or order function.

PLS-00525: Within SQL statements, only equality comparisons of objects are allowed without a map or order function.
Cause: A map or order function was not provided for a relational comparison. Only equality comparisons may be used when a map or order function is not supplied.
Action: Supply either a map or order function for the object. Otherwise change the program to use only equality comparisons.

PLS-00525：在SQL语句中，仅允许对象的等式比较，而不使用映射或顺序函数。,
.原因：没有为关系比较提供地图或订单功能。当不提供地图或订单功能时，只能使用相等比较。,
.操作：为对象提供地图或订单函数。否则将程序更改为仅使用等式比较。,
