Oracle Error PLS-00384: type mismatch found at ‘string’ in UPDATE’s SET clause

Oracle Error Message

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

Reason for the Error

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.

Solution

Change the expressions so that their datatypes match. You might want to use datatype conversion functions in the SET clause.
