Question

我有这样的存储过程：

ALTER procedure [dbo].[carcallvalidation]
@carid nvarchar(100)=null
as
begin
    select count(*)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;
if(select count(k.transactid) from KHanger_tbl k where k.transactid=@transid)>0
begin
return 1
end
end

我想得到T.TBarcode的数量执行错误时会出现这样的错误：'。'。

附近的语法不正确

Answer 1

尝试以下商店程序：

ALTER procedure [dbo].[carcallvalidation] @carid nvarchar(100)=null
as
begin

    select sum(case when t.TBarcode is null then 0 else 1 end) as cnt, t.Paid,t.Status,t.DelDate
    from Transaction_tbl t
    where TBarcode=@carid
    group by t.Paid,t.Status,t.DelDate;

    declare @transid integer=null;

    select @transid= t1.transactID from Transaction_tbl t1 where TBarcode=@carid;
    if(select count(k.transactid) from KHanger_tbl k where k.transactid=@transid)>0
    begin
     return 1
    end
end

Answer 2

选择 count(*)t.TBarcode ，t.Paid，t.Status，t.DelDate 来自Transaction_tbl t。粗体陈述是您回答的地方不正确的地方。这不可能是count(*)t.TBarcode。

在条件

之后添加以下内容

group by t.Paid,t.Status,t.DelDate;

如果您想要t.paid之和，请不要将其放入group by子句中。

ALTER procedure [dbo].[carcallvalidation]
@carid nvarchar(100)=null
as
begin
    select count(t.TBarcode) as count, sum(t.Paid),t.Status,t.DelDate
    from Transaction_tbl t
    where TBarcode=@carid;

    group by t.status,t.DelDate

    declare @transid integer=null;
   select @transid= t1.transactID from Transaction_tbl t1 where TBarcode=@carid;
if(select count(k.transactid) from KHanger_tbl k where k.transactid=@transid)>0
begin
return 1
end
end

Answer 3

ALTER procedure [dbo].[carcallvalidation]
@carid nvarchar(100)=null
as
begin
    select count(t.TBarcode) as barcodeCount, t.Paid,t.Status,t.DelDate
    from Transaction_tbl t
    where TBarcode=@carid;

    group by t.paid,t.status,t.DelDate

    declare @transid integer=null;
   select @transid= t1.transactID from Transaction_tbl t1 where TBarcode=@carid;
if(select count(k.transactid) from KHanger_tbl k where k.transactid=@transid)>0
begin
return 1
end
end
