Read an ARRAY from a STRUCT returned by a stored procedure

Question

In the database are three Oracle custom types (simplified) as follows:

create or replace TYPE T_ENCLOSURE AS OBJECT(
  ENCLOSURE_ID      NUMBER(32,0),
  ENCLOSUR         


        

Answer 1

I Just share the logic which worked for me. You can try this to retrieve ARRAY response from PL/SQL to Java.

CallableStatement callstmt = jdbcConnection.prepareCall("{call PROCEDURE_NAME(?, ?)}");
callstmt.setArray(1, array);
callstmt.registerOutParameter(2,Types.ARRAY, );
// Do all execute operations
    Array arr = callstmt.getArray(1);
            if (arr != null) {
               Object[] data = (Object[]) arr.getArray();
               for (Object a : data) {
                   OracleStruct empstruct = (OracleStruct) a;
                   Object[] objarr = empstruct.getAttributes();
                    r = new (objarr[0].toString(), objarr[1].toString());
                   System.out.println("Response-> : "+ r.toString());
               }
            }
