PLS-00384: type mismatch found at 'string' in UPDATE's SET clause

PLS-00384: type mismatch found at 'string' in UPDATE's SET clause
Cause: The column to the left of the equal sign in the SET clause of an UPDATE statement does not match in datatype with the column, expression, or subquery to the right of the equal sign, and it is unclear which implicit conversion is required to correct the mismatch.
Action: Change the expressions so that their datatypes match. You might want to use datatype conversion functions in the SET clause.

PLS-00384：在UPDATE的SET子句中的' string ' 处找到类型不匹配,
.原因： UPDATE语句的SET子句中等号左边的列在数据类型中与等号右侧的列，表达式或子查询不匹配，并且不清楚哪个隐式转换需要纠正不匹配。,
.操作：更改表达式，使其数据类型匹配。您可能希望在SET子句中使用数据类型转换函数。,
