Oracle's RETURNING INTO usage in Java (JDBC, Prepared Statement)

Question

I\'m using JDBC to execute Oracle statement which looks like this:

\"INSERT INTO MYTABLE(MYDATA) VALUES(?) RETURNING MY_CALCULATED_DATA INTO ?\"
// MYTABLE\'         


        

Answer 1

Because parameters specified in returning clauses are handled in a different way compared to normal output parameters(getReturnResultSet vs getResultSet vs returning parameters in a callablestatement).
They need to be handled with OraclePreparedStatement. In the second case when you wrap the insert statement in begin..end the insert is handled by the database itself and al jdbc sees is an anonymous plsql block.
