我正在使用表变量重写存储过程。基本上我有一个列表,我将其传递给 DataTable,然后将数据表作为表变量传递给存储过程。存储过程可以正确编译,但是当我在 SSMS 或 .Net 中执行它时,我得到了 Invalid object name '@TableVar'。我是新手,所以非常感谢你的帮助。
Alter PROCEDURE [dbo].[proc]
(
@TableVar [dbo].[TableVar] READONLY
)
AS
BEGIN
Set nocount on
Declare @MYID INT
Declare @SOMEDate DateTime
Declare @NEWDate Date
select @MYID = some_id,
@SOMEDate = convert(date, db_some_date) from tbl_some
where someval = (select tb.val1 from [@TableVar] as tb);
Merge OneTabl as target
using (Select x.val1, x.val2, x.val3,x.val4,
x.val5,x.val6, x.val7 from [@TableVar] as x)
as Source
on val_id = @MYID
when matched and @MYID !=NULL then
update set MDN= Source.[MDN],
val1= Source.[val1],
val2=Source.[val2],
val3=Source.[val3],
val4=Source.[val4],
val5=Source.[val5],
val6=Source.[val6]
when not matched and @MYID !=NULL then
insert
values (Source.[val1],
Source.[val2],
Source.[val3],
Source.[val4],
Source.[val5],
Source.[val6],
Source.[val7],
[@MYID]
) ;
end
