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
在执行存储过程时,我会像这样退出:
Tbarcode paid status
1111 0 2
Transid
2
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
