sql - 从存储过程中获取第二行值

Question

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

返回值 0

如何在 vb.net 中获取 Transid 值？我像这样获取第一行值：

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

在获取这样的transid值时出现错误，有没有办法获取第二行值

Answer 1

从 DataReader 请求值：

Transid= dr("Transid")

请记住在每个 IDisposable 成员实例（如 DataReader、Command 和 DbConnection）上调用 Dispose()
