How to call a PL/SQL stored function through Java EntityManager

Question

I have this function

create or replace
FUNCTION IFRS_FUNCTION_TEST RETURN NUMBER IS

estado NUMBER;
excepciones NUMBER;
title_code VARCHAR2(150 char);
colgaap_code VARCHAR2(150 char);
ifrs_code VARCHAR2(150 char);
v_causacion VARCHAR2(150 char);
pyg_diario_value VARCHAR2(150 char);
fecha_valoracion VARCHAR2(150 char);
pyg_dialogo VARCHAR2(150 char);

CURSOR ifrscursor IS SELECT no_asignado_por_la_entidad, codigo_puc FROM IFRS_351 WHERE no_asignado_por_la_entidad LIKE 'W%' FOR UPDATE;

BEGIN
        BEGIN
        estado:=0;
        excepciones:=0;
        OPEN ifrscursor;
        LOOP
            FETCH ifrscursor INTO title_code, colgaap_code; 
            EXIT WHEN ifrscursor%NOTFOUND;
            SELECT cta_ifrs into ifrs_code FROM ifrs_tabla_homo_351 WHERE codigo_puc_colgaap = colgaap_code;
            UPDATE IFRS_351 SET codigo_puc = ifrs_code WHERE CURRENT OF ifrscursor;
            BEGIN
                SELECT saldo, pyg_diario into v_causacion, pyg_diario_value FROM IFRS_INV_OBL WHERE nro_titulo=title_code;
                UPDATE IFRS_351 SET vr_mercado_o_valor_presente_ = v_causacion, causacion_valoracion_cuentas = pyg_diario_value WHERE CURRENT OF ifrscursor;
            EXCEPTION WHEN NO_DATA_FOUND THEN
                excepciones:=excepciones+1;
            END;
END LOOP; 
CLOSE ifrscursor;
EXCEPTION WHEN OTHERS THEN
    estado:=SQLCODE;  
END;
RETURN(estado);

How can I get the estado value of this function with Java EntityManager? I tried with

SELECT IFRS_FUNCTION_TEST() FROM DUAL;

but I always obtain the error code 14551.

Answer 1

The value -14551 is actually an Oracle error rather than a value. The error is detailed below and should give more details on exactly why it's not working.

ORA-14551 cannot perform a DML operation inside a query Cause: DML operation like insert, update, delete or select-for-update cannot be performed inside a query or under a PDML slave. Action: Ensure that the offending DML operation is not performed or use an autonomous transaction to perform the DML operation within the query or PDML slave.
