c#中利用pl/sql匿名塊和遊标擷取多個結果集

1.建立測試表并插入資料：

SQL> create table TESTTAB1

  2  (

  3    NAME1 VARCHAR2(10)

  4  );

表被建立

SQL>

SQL> create table testtab2

  2  (

  3    name2 varchar2(10)

  4  )

  5  ;

表被建立

SQL> insert into testtab1 values('testtab1');

1 行 已插入

SQL> commit;

送出完成

SQL> insert into testtab2 values('testtab2');

1 行 已插入

SQL> commit;

送出完成

SQL>

2.驗證插入的資料：

SQL> select * from testtab1;

NAME1

----------

testtab1

SQL> select * from testtab2;

NAME2

----------

testtab2

SQL>

3.主要的c# 代碼：

using ORAC = System.Data.OracleClient;

private void button1_Click(object sender, System.EventArgs e)

{

     try

              {

                   string str_Sql = @"begin open :cur1 for select * from testtab1;open :cur2 for select * from testtab2;end;";

                   ORAC.OracleCommand cmd = new ORAC.OracleCommand(str_Sql,this.oracleConnection1);

                   ORAC.OracleParameter parm1 = new ORAC.OracleParameter("cur1",ORAC.OracleType.Cursor);

                   parm1.Direction = ParameterDirection.Output;

                   cmd.Parameters.Add(parm1);

                   ORAC.OracleParameter parm2 = new ORAC.OracleParameter("cur2",ORAC.OracleType.Cursor);

                   parm2.Direction = ParameterDirection.Output;

                   cmd.Parameters.Add(parm2);

                   ORAC.OracleDataAdapter da = new ORAC.OracleDataAdapter();

                   da.SelectCommand = cmd;

                   DataSet ds = new DataSet();

                   da.Fill(ds);

                   this.dataGrid1.DataSource = ds.Tables[0].DefaultView;

                   this.dataGrid2.DataSource = ds.Tables[1].DefaultView;

              }

              catch(Exception ex)

              {

                   MessageBox.Show(ex.Message);

              }

              finally

              {

                   this.oracleConnection1.Close();

              }

}
