public void Get_PrecedureData()
{
OracleConnection connection = null;//Connection
OracleCommand oraCommand = new OracleCommand();
OracleParameter paramId = null;
OracleParameter paramTbl = null;
OracleParameter paramCur = null;
OracleRefCursor pInfoCur = null;
DataSet dtRtn = new DataSet();
//数据库连接
connection = new OracleConnection("User Id=scott;Password=tiger;Data Source=oracle");
connection.Open();
oraCommand.Connection = connection;
oraCommand.Parameters.Clear();
// 存储过程 设定
oraCommand.CommandText = "PKG_TEST.PROC_GET_DATA";
oraCommand.CommandType = System.Data.CommandType.StoredProcedure;
// 输入输出参数设定
// Varchar2型
paramId = oraCommand.Parameters.Add( "I_ID", OracleDbType.Varchar2, ParameterDirection.Input );
// 数组类型参数设定
paramTbl = oraCommand.Parameters.Add( "I_TBL", OracleDbType.Varchar2, ParameterDirection.Input );
// 将CollectionType 设为 PLSQLAssociativeArray
paramTbl.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
//cursor 类型参数设定
paramCur = oraCommand.Parameters.Add("O_CUR", OracleDbType.RefCursor, ParameterDirection.Output );
//设置参数数组的大小
//注意：参数的Value 属性和ArrayBindSize 属性必须为元素个数相同的数组，且个数等于参数的Size 属性
int[] bindSize = new int[10];
string[] tblData = new string[10];
for(int ii = 0; ii < 10; ii++)
{
tblData[ii] = ii.ToString();//数值
bindSize[ii] = 10;//数值的大小
}
//数组参数设定
paramTbl.Value = tblData;
paramTbl.Size = 10;
paramTbl.ArrayBindSize = bindSize;
//存储过程执行
oraCommand.ExecuteNonQuery();
//out的cursor值的读取
using(OracleDataAdapter da = new OracleDataAdapter())
{
if(paramCur.Value != System.DBNull.Value)
{
pInfoCur = (OracleRefCursor)paramCur.Value;
da.Fill(dtRtn, pInfoCur);
}
//取得记录数
Console.WriteLine("the number of record count is {0}", dtRtn.Tables[0].Rows.Count);
}
oraCommand.Dispose();
connection.Close();
connection.Dispose();
}
