C#程序调用Oracle的Packages函数

1.  oracle 增加package部分

 

CREATE OR REPLACE PACKAGE BODY Interface_PKG AS

  PROCEDURE GetTableData(IN_WorkDate IN Date, IO_CURSOR OUT T_CURSOR) IS
    V_CURSOR    T_CURSOR;
  BEGIN
  
    OPEN V_CURSOR FOR
    
      select *
        from 测试表
       where workdate = IN_WorkDate;
  
    IO_CURSOR := V_CURSOR;
  
  End GetTableData;

END Interface_PKG;

 

 

 

 

2, C# 获取数据部分

        public DataTable getTableFromPKG(string Procedures ,DateTime Date)
        {

            OracleConnection conn = new OracleConnection(System.Configuration.ConfigurationSettings.AppSettings["scott"]);
            System.Data.OracleClient.OracleCommand Com = new System.Data.OracleClient.OracleCommand();
            Com.Connection = conn;
            Com.Parameters.Clear();
            Com.CommandText = Procedures;
            Com.CommandType = CommandType.StoredProcedure;
            Com.Parameters.Add(new System.Data.OracleClient.OracleParameter("IN_WorkDate", System.Data.OracleClient.OracleType.DateTime)).Direction = ParameterDirection.Input;
            Com.Parameters.Add(new System.Data.OracleClient.OracleParameter("IO_CURSOR", System.Data.OracleClient.OracleType.Cursor)).Direction = ParameterDirection.Output;
            Com.Parameters[0].Value = Date;
            DataSet ds = new DataSet();
            System.Data.OracleClient.OracleDataAdapter Oda = new System.Data.OracleClient.OracleDataAdapter(Com);

            if (conn.State == 0) conn.Open();

            Oda.Fill(ds);

            DataTable dt = new DataTable();

            dt = ds.Tables[0];
            return dt;
        }
