c# 调用带有参数的存储过程方法--oracle【转载】

首先，定义包，然后定义包体，在用.net调用生成数据集即可

.net调用oracle带参数的存储过程，返回数据集

Oracle这个复杂一些，步骤如下：

在pl/sql中首先写包的定义文件

CREATE OR REPLACE PACKAGE ZHBB AS
    TYPE t_cursor IS REF CURSOR ;
Procedure ZH11 (rq IN char, io_cursor IN OUT t_cursor);

Procedure ZH12 (rq IN char, io_cursor IN OUT t_cursor);

END ZHBB;

其次写包体的定义文件

CREATE OR REPLACE PACKAGE BODY ZHBB AS

  Procedure ZH11(rq IN char, io_cursor IN OUT t_cursor) IS

    v_cursor t_cursor;

  BEGIN

    OPEN v_cursor FOR

Select * from aa where ny=rq;

  io_cursor := v_cursor;

  END ZH11;

Procedure ZH12 (rq IN char, io_cursor IN OUT t_cursor) IS

。。。。。

END ZH12;

.net调用方法：

   public static DataTable GetDataTable(string PackageName,string ProName,string connString,string rq)

         {

connString=” Provider= MSDAORA.1;User ID=xx;Data Source=xx;Password=xx;”

 //定义下新的链接方法，因为原来的驱动"OraOLEDB.Oracle"不能满足需求，设置为"MSDAORA.1"

            OleDbConnection raclecon = new OleDbConnection(connString);

            Oraclecon.Open();

            OleDbCommand cmd = new OleDbCommand("{Call "+ PackageName +"."+ ProName +"(?, {resultset 0, io_cursor} )}", Oraclecon);

            cmd.Connection = Oraclecon;

            cmd.Parameters.Add("rq", OleDbType.VarChar, 8).Value = ""+ rq +"";

            OleDbDataAdapter da = new OleDbDataAdapter(cmd);

            DataTable dt = new DataTable();

            //DataSet ds = new DataSet();

            da.Fill(dt);

            Oraclecon.Close();

            Oraclecon.Dispose();

            return dt;

         }

}
