Ben <em>Java</em> kodundan paketin <code>ult_pkg</code> Bu prosedürü <code>get_data_Q1</code> arayıp koymak out görüntülemek istediğiniz bir java sınıfından

Question

gelen tablo türü olarak dışarı parametresi prosedürü çağırmak nasıl, herhangi biri lütfen bana yardımcı olabilir. Şimdiden teşekkürler.

CREATE OR REPLACE PACKAGE ult_pkg 
AS 
TYPE t_all_record is record (
    x_object_type_id  number, 
    x_object_name   varchar2(100), 
    x_object_id    varchar2(70), 
    x_audit_timestamp  timestamp(6), 
    x_payload    clob 
); 

--table type to hold table data after querying 

type tt_all_tab is table of t_all_record index by binary_integer; 

--declaration pocedures 
procedure get_data_Q1(x_object_id in varchar2 , x_all_type out tt_all_tab); 


end ult_pkg; 

/

oluşturabilir veya

--procedure taking 'object_id' as input parameter and gives out table of 't_all_record' type 
procedure get_data_Q1(x_object_id in varchar2 , x_all_type out tt_all_tab) 
AS 

    i number:=0; 
begin 

    for r in 
     ( 
      SELECT 
      O.object_type_id,O.object_name,O.object_id,A.audit_timestamp,P.payload 
      FROM 
      APPLICATION APP, EXCEPTIONS E,MASTER_AUDIT A,MODULE_TYPE M,OBJECT_TYPE O,PAYLOAD P 
      WHERE 
      (A.MODULE_TYPE_ID = M.MODULE_TYPE_ID) AND (M.APPLICATION_ID = APP.APPLICATION_ID) AND (A.OBJECT_TYPE_ID = O.OBJECT_TYPE_ID) AND (O.OBJECT_ID = x_object_id) 
     ) 
    -- loop to asign the data from cursor 'r' to carasponding table type columns 
     loop 


     x_all_type(i).x_object_type_id:=r.object_type_id; 
     x_all_type(i).x_object_name:=r.object_name; 
     x_all_type(i).x_object_id:=r.object_id; 
     x_all_type(i).x_audit_timestamp:=r.audit_timestamp; 
     x_all_type(i).x_payload:=r.payload; 
     i:=i+1; 
     end loop; 

    end get_data_Q1; 

gibi son ult_pkg ult_pkg paket vücut yerine 'ult_pkg' paketinin

--body; /

Answer 1

Bu mümkün değil, Accessing PL/SQL Index-by Tables bkz:

Oracle JDBC eleman türleri olarak RAW, TARİH ve PL/SQL KAYIT desteklemez.

muhtemelen şöyle bir özel (küresel değil, paket) nesne türünü kullanmayı tercih ediyorum

: paketinize

CREATE TYPE t_all_record AS OBJECT (
    x_object_type_id  number, 
    x_object_name   varchar2(100), 
    x_object_id    varchar2(70), 
    x_audit_timestamp  timestamp(6), 
    x_payload    clob 
) 
/
CREATE TYPE t_all_records IS TABLE OF t_all_record 
/

referans tipi tablosu (t_all_records yerine tt_all_tab ait) ve şöyle doldurun

procedure get_data_Q1(x_object_id in varchar2 , x_all_type out t_all_records) 
AS 
begin 
    SELECT t_all_record(O.object_type_id,O.object_name,O.object_id,A.audit_timestamp,P.payload) 
    BULK COLLECT INTO x_all_type 
    FROM APPLICATION APP, EXCEPTIONS E,MASTER_AUDIT A,MODULE_TYPE M,OBJECT_TYPE O,PAYLOAD P 
    WHERE (A.MODULE_TYPE_ID = M.MODULE_TYPE_ID) AND (M.APPLICATION_ID = APP.APPLICATION_ID) AND (A.OBJECT_TYPE_ID = O.OBJECT_TYPE_ID) AND (O.OBJECT_ID = x_object_id) 
end get_data_Q1; 

Sonucu şöyle java gelen kullanılabilir olacaktır:

package tests.jdbc; 

import java.sql.Array; 
import java.sql.CallableStatement; 
import java.sql.Connection; 
import java.sql.DriverManager; 
import java.sql.ResultSetMetaData; 
import java.sql.Struct; 
import java.sql.Types; 

import oracle.sql.StructDescriptor; 

public class OracleTableOfResult { 
    public static void main(String...a) throws Exception { 
     Class.forName("oracle.jdbc.OracleDriver"); 
     Connection connection = DriverManager.getConnection("jdbc:oracle:thin:<USER>/<PASS>@<DATABASEHOST>:1521:<SERVICE>"); 

     final String typeName = "T_ALL_RECORD"; 
     final String typeTableName = "T_ALL_RECORDS"; 

     // Get a description of your type (Oracle specific) 
     final StructDescriptor structDescriptor = StructDescriptor.createDescriptor(typeName.toUpperCase(), connection);   
     final ResultSetMetaData metaData = structDescriptor.getMetaData(); 

     // Call the procedure (or whatever else) that returns the table of a custom type 
     CallableStatement cs = connection.prepareCall("{call ult_pkg.get_data_Q1(?, ?)}"); 
     cs.setString(1, "the_id"); 
     // Result is an java.sql.Array... 
     cs.registerOutParameter(2, Types.ARRAY, typeTableName);  
     cs.execute(); 

     // ...who's elements are java.sql.Structs 
     Object[] data = (Object[]) ((Array) cs.getObject(2)).getArray(); 
     for(Object tmp : data) { 
      Struct row = (Struct) tmp; 
      // Attributes are index 1 based... 
      int idx = 1; 
      for(Object attribute : row.getAttributes()) {    
       System.out.println(metaData.getColumnName(idx) + " = " + attribute);            
       ++idx; 
      } 
      System.out.println("---"); 
     } 
     cs.close();  
     connection.close(); 
    } 
} 

Ama sonuçta, eğer hazır bir deyim olarak sorgunuzu sade bir sql deyiminde kullanabiliyor olsanız çabaya değer…
