尝试使用 CTE FREETEXTTABLE 索引视图时出现严重错误

发布于 2024-07-25 09:12:52 字数 951 浏览 8 评论 0原文

当 stockView 是带有全文索引的索引视图时，我收到以下错误消息。该数据库在 2008 Express 引擎上以 2005 兼容模式运行。

代码：

with stockCte (title, grade, price, weighted)
as
(
    select sv.[title]                   ,
            sv.[grade]                  ,
            sv.[price]                  ,
            (case when sv.[issue] = @issue and svs.[rank] > 30
                then svs.[rank] + 100
                else svs.[rank]
                end)                    weighted
    from stockView sv
    inner join freetexttable(stockView, (name), @term) svs
        on sv.[id] = svs.[key]
)
select * from stockCte;

错误：

Msg 0, Level 11, State 0, Line 0
A severe error occurred on the current command.  The results, if any, should be discarded.
Msg 0, Level 20, State 0, Line 0
A severe error occurred on the current command.  The results, if any, should be discarded.

当我删除内部联接和加权列时，查询有效。任何想法，我都不知所措。

原文

Where stockView is an indexed view with a full-text index, I receive the error message below. The database is running on a 2008 Express engine in 2005 compatibility mode.

Code:

with stockCte (title, grade, price, weighted)
as
(
    select sv.[title]                   ,
            sv.[grade]                  ,
            sv.[price]                  ,
            (case when sv.[issue] = @issue and svs.[rank] > 30
                then svs.[rank] + 100
                else svs.[rank]
                end)                    weighted
    from stockView sv
    inner join freetexttable(stockView, (name), @term) svs
        on sv.[id] = svs.[key]
)
select * from stockCte;

Error:

Msg 0, Level 11, State 0, Line 0
A severe error occurred on the current command.  The results, if any, should be discarded.
Msg 0, Level 20, State 0, Line 0
A severe error occurred on the current command.  The results, if any, should be discarded.

The query works when I remove the inner join and the weighted column. Any ideas, I'm at a loss.

我很不情愿地使用表变量而不是 CTE。

declare @stockTemp table(
    title               nvarchar(100),
    grade               nvarchar(50),
    price               money,
    row                 bigint
);

insert into @stockTemp
select sv.[title]                   ,
        sv.[grade]                  ,
        sv.[price]                  ,
        row_number() over (order by (case when sv.[issue] = @issue and svs.[rank] > 30
                                            then svs.[rank] + 100
                                            else svs.[rank]
                                            end) desc,
                                        sv.title,
                                        sv.grade desc,
                                        sv.price asc)
from stockView sv
inner join freetexttable(stockView, (*), @term) svs
    on sv.[id] = svs.[key]

select * from @stockTemp;

如果有人有更好的建议，请告诉我。

Reluctantly I have resorted to using a table variable instead of a CTE.

declare @stockTemp table(
    title               nvarchar(100),
    grade               nvarchar(50),
    price               money,
    row                 bigint
);

insert into @stockTemp
select sv.[title]                   ,
        sv.[grade]                  ,
        sv.[price]                  ,
        row_number() over (order by (case when sv.[issue] = @issue and svs.[rank] > 30
                                            then svs.[rank] + 100
                                            else svs.[rank]
                                            end) desc,
                                        sv.title,
                                        sv.grade desc,
                                        sv.price asc)
from stockView sv
inner join freetexttable(stockView, (*), @term) svs
    on sv.[id] = svs.[key]

select * from @stockTemp;

If anyone has any better suggestions, please let me know.
