VB.net 调用带参数存储过程

--1:存储过程返回DataSet 的例子:

C# 代码 :通用类

public static int SingleSTCD(DateTime StartTime,DateTime EndTime,int SMTP,
　string JL,string STDCD,string STCDSTR, out DataSet ds )
  {
   int ret=0;
   ds=null;
 
OleDbConnection Constring=new OleDbConnection(Appraise.ConStr);
OleDbCommand cmd=new OleDbCommand("P_Get_STCD_SingleAppraise_XunQi",
　Constring);
try
{
OleDbDataAdapter ada=new OleDbDataAdapter();
  cmd.CommandType=CommandType.StoredProcedure;
  cmd.Parameters.Add("@StartTime", OleDbType.DBTimeStamp).Value=StartTime ;
  cmd.Parameters.Add("@EndTime", OleDbType.DBTimeStamp).Value=EndTime ;
  cmd.Parameters.Add("@SMTP", OleDbType.Integer).Value=SMTP ;
  cmd.Parameters.Add("@JL", OleDbType.VarChar, 50).Value=JL ;
  //cmd.Parameters.Add("@STDCD", OleDbType.VarChar, 50).Value=STDCD ; 
　 //评价标准

cmd.Parameters.Add("@STCDSTR", OleDbType.VarChar, 8000).Value=STCDSTR ;

System.Data.DataSet data = new DataSet();
  ada.SelectCommand = cmd;
  ada.Fill(data,"table");
  ds = data;
  ret=ds.Tables[0].Rows.Count;
  if ( ret ==-1 )
  {
   return -1000; //无数据
  }
  else
  {
   return ret;
  }

}
catch(Exception e)
{
  //数据库操作发生错误,返回错误代码
  System.Diagnostics.Debug.WriteLine(e.Message);
  return -1001;
}
finally
{
  Constring.Close();
  cmd.Parameters.Clear();
}

VB.net 调用:

Private Sub BindingDataGrid_Query()
  Dim ds As System.Data.DataSet
  Zehua.Water.Appraise.SingleSTCD("1999-5-1", "1999-9-1", 1, "Ⅲ", "", "50181300,50185050,50181350,50185100,50185150,50185200,50185250,
50181200,50185150,51282300", ds)
  DataGrid_Query.DataSource = ds
  DataGrid_Query.DataBind()
End Sub

--1:存储过程返回数组字符串

REM 执行存储过程,返回一数组
Public Shared Function ExecuteSP_ToArrary(ByVal sConnString As String,
ByVal Text_STCD As String, ByVal Text_TIME As String,
 ByRef TableInfo() As String)
  Dim conn As OleDbConnection = New OleDbConnection(sConnString)
  ReDim TableInfo(2)

Try
   conn.Open()
 Dim command As OleDbCommand = New OleDbCommand("P_GET_QueryValue", conn)
 command.CommandType = CommandType.StoredProcedure
 Dim sqlParams() As OleDbParameter = {New OleDbParameter("@STCD", Text_STCD),
New OleDbParameter("@GETM", Text_TIME),
New OleDbParameter("@ReturnValue", OleDbType.VarChar, 8000),
New OleDbParameter("@ReturnColumnCode", OleDbType.VarChar, 8000),
New OleDbParameter("@ReturnColumnName", OleDbType.VarChar, 8000)}
   sqlParams(2).Direction = ParameterDirection.Output
   sqlParams(3).Direction = ParameterDirection.Output
   sqlParams(4).Direction = ParameterDirection.Output
   Dim i As Integer = 0
   While i < sqlParams.Length
command.Parameters.Add(sqlParams(i))
i += 1
   End While
   command.ExecuteNonQuery()
   If sqlParams(2).Value.ToString().Length > 0 Then
TableInfo(0) = sqlParams(2).Value.ToString()
   Else
   End If

If sqlParams(3).Value.ToString().Length > 0 Then
TableInfo(1) = sqlParams(3).Value.ToString()
   Else
   End If

If sqlParams(4).Value.ToString().Length > 0 Then
TableInfo(2) = sqlParams(4).Value.ToString()
   Else
   End If

Catch ex As Exception
   ZeHua.Log.exNoteBugs(ex, "SigleStcdEdit.aspx") 'sb.Append(ex.Message)
  Finally
   conn.Close()
  End Try

End Function
