sqlcode -433

SQLCODE -433 indicates that the SQL statement failed because a column or parameter reference was ambiguous. This means that the identifier used in the statement could refer to multiple columns or parameters, and the database engine was unable to determine which one to use.

To resolve this error, you need to modify the SQL statement to make the reference unambiguous. One way to do this is to qualify the column or parameter reference with the table or routine name. Another way is to use an alias to differentiate between similar column or parameter names.

For example, instead of writing:

SELECT id, name FROM customer WHERE name = 'John';

you could write:

SELECT customer.id, customer.name FROM customer WHERE customer.name = 'John';

or

SELECT c.id, c.name FROM customer c WHERE c.name = 'John';

Both of these statements make the reference unambiguous by qualifying the column names with the table name or using an alias.
