PLS-00386: type mismatch found at string between FETCH cursor and INTO variables

PLS-00386: type mismatch found at string between FETCH cursor and INTO variables

Cause: An assignment target in the INTO list of a FETCH statement does not match in datatype with the corresponding column in the select list of the cursor declaration, and it is unclear which implicit conversion is required to correct the mismatch.

Action: Change the cursor declaration or change the datatype of the assignment target. You might want to use datatype conversion functions in the select list of the query associated with the cursor.
