Sql server 在SQL Server中从选择查询合并多个结果

我有这个SQL块代码

use TestDatabase

declare @keyword nvarchar(1000) = '';
declare @sqlKeyword nvarchar(1000) = '';

set @sqlKeyword =
    'select * into #tmphosovanban from TblHoSoVB
            select *  from(
                select * from (
                --tim tu khoa theo district
                        ( select * from  #tmphosovanban
                            where  DCHCHuyenID in (select DistrictID from MstDistrict where DistrictName like N''%'+@keyword+'%'' )
                            or DatHCHuyenID in (select DistrictID from MstDistrict where DistrictName like N''%'+@keyword+'%'' )
                             )
                        union

                --tim tu khoa theo town
                        (select * from  #tmphosovanban
                            where DCHCXaID in (select TownID from MstTown where TownName like N''%'+@keyword+'%'')
                            or DatHCXaID in (select TownID from MstTown where TownName like N''%'+@keyword+'%'')
                            )
                        union
                --tim tu khoa theo nguon goc dat
                        (select * from  #tmphosovanban
                            where NGSuDungDatID in (select MasterID from MstCommonMaster where MasterName like N''%'+@keyword+'%'')
                            or MDSuDungDatID in (select MasterID from MstCommonMaster where MasterName like N''%'+@keyword+'%'')
                            or LoaiTaiSanID in (select MasterID from MstCommonMaster where MasterName like N''%'+@keyword+'%'')
                            )
                        union 
                        (select * from  #tmphosovanban
                            where ViTriLuuID in (select GiaID from MstViTriGia where TenGia like N''%'+@keyword+'%'')
                        )

                ) as temp
        ) as temp2 
        drop table #tmphosovanban'
exec(@sqlKeyword)

我犯了一个错误

味精102，第15级，状态1，第21行
“'）附近的语法不正确

当我在SQL Server上运行此块时。我不知道为什么是错的。当我删除下面的一个块时，它会运行，所以我认为我的语法是正确的，因为另一个原因，它不会运行。我怎样才能解决这个问题

        --tim tu khoa theo district
                ( select * from  #tmphosovanban
                    where  DCHCHuyenID in (select DistrictID from MstDistrict where DistrictName like N''%'+@keyword+'%'' )
                    or DatHCHuyenID in (select DistrictID from MstDistrict where DistrictName like N''%'+@keyword+'%'' )
                     )
                union


        --tim tu khoa theo town
                (select * from  #tmphosovanban
                    where DCHCXaID in (select TownID from MstTown where TownName like N''%'+@keyword+'%'')
                    or DatHCXaID in (select TownID from MstTown where TownName like N''%'+@keyword+'%'')
                    )
                union

        --tim tu khoa theo nguon goc dat
                (select * from  #tmphosovanban
                    where NGSuDungDatID in (select MasterID from MstCommonMaster where MasterName like N''%'+@keyword+'%'')
                    or MDSuDungDatID in (select MasterID from MstCommonMaster where MasterName like N''%'+@keyword+'%'')
                    or LoaiTaiSanID in (select MasterID from MstCommonMaster where MasterName like N''%'+@keyword+'%'')
                    )
                union

您的问题是，您定义了一个变量，该变量包含

1000

个字符，并在notepad++中计算字符串查询。我注意到字符串包含

1770+

个字符，因此SQL Server正在截断您的字符串，因此尝试执行不完整的查询

---

将变量更改为

@sqlKeyword-nvarchar（2000）

，您应该会没事。

您的变量

@sqlKeyword-nvarchar（1000）

小于查询中的字符量，因此将其增加到，比如说，2000。让我知道，如果它解决了你的问题，我会补充作为一个答案。谢谢。它解决了我的问题
