I have stored procedure like this:
我有这样的存储过程:
ALTER procedure [dbo].[carcallvalidation]
@carid nvarchar(100)=null
as
begin
select t.TBarcode, t.Paid,t.Status,t.DelDate from Transaction_tbl t where TBarcode=@carid
declare @transid integer=null
select @transid= t1.transactID from Transaction_tbl t1 where TBarcode=@carid
select count(k.transactid) transid from KHanger_tbl k where k.transactid=@transid
end
while executing stored procedure i am getting out put like this:
Tbarcode paid status
1111 0 2
Transid
2
Return value 0
返回值为0
How I can fetch Transid value in vb.net? I Fetchd first row value like this:
如何在vb.net中获取传递值?我获取第一行的值如下所示:
Dim cmdcarvalidation As New SqlCommand("carcallvalidation", con.connect)
cmdcarvalidation.CommandType = CommandType.StoredProcedure
cmdcarvalidation.Parameters.Add("@carid", SqlDbType.VarChar, 50, ParameterDirection.Input).Value = txtTicket.Text
dr = cmdcarvalidation.ExecuteReader
While dr.Read
tbarcode=dr("Tbarcode")
payd= dr("paid")
status= dr("status")
end while
while fetching transid value like this am getting error,,,is there any way to fetch second row value
当像这样获取transid值时,会出现错误,有办法获取第二行值吗
