从C#调用Oracle存储过程?
如何从C#调用oracle中的存储过程?
回答:
请访问由oracle为Microsoft OracleClient
Developers设置的ODP网站:http

同样在下面是示例代码,可以帮助您开始从C#到Oracle调用存储过程。PKG_COLLECTION.CSP_COLLECTION_HDR_SELECT是在Oracle上构建的存储过程,接受参数PUNIT,POFFICE,PRECEIPT_NBR并将结果返回到T_CURSOR。
using Oracle.DataAccess;using Oracle.DataAccess.Client;
public DataTable GetHeader_BySproc(string unit, string office, string receiptno)
{
using (OracleConnection cn = new OracleConnection(DatabaseHelper.GetConnectionString()))
{
OracleDataAdapter da = new OracleDataAdapter();
OracleCommand cmd = new OracleCommand();
cmd.Connection = cn;
cmd.InitialLONGFetchSize = 1000;
cmd.CommandText = DatabaseHelper.GetDBOwner() + "PKG_COLLECTION.CSP_COLLECTION_HDR_SELECT";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("PUNIT", OracleDbType.Char).Value = unit;
cmd.Parameters.Add("POFFICE", OracleDbType.Char).Value = office;
cmd.Parameters.Add("PRECEIPT_NBR", OracleDbType.Int32).Value = receiptno;
cmd.Parameters.Add("T_CURSOR", OracleDbType.RefCursor).Direction = ParameterDirection.Output;
da.SelectCommand = cmd;
DataTable dt = new DataTable();
da.Fill(dt);
return dt;
}
}
