VB.net 调用带参数存储过程(转载)

--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
