为什么我的SQL查询试图将nvarchar值转换为int？ （使用CONTAINSTABLE（））

Question

I am trying to get the FullText Search working in SQL Server 2008 R2. I have been working with our admin and we believe we have a catalog with indexes successfully set up. Now, I'm trying to query the indexed table using FullText functions

This works without a problem:

select *
from mPages
where contains(bodytext, ' "a dog" ')

However, when I try to get rank values by using containstable() , I get an error.

select mPages.bodytext, KEY_TBL.RANK
from mPages
     INNER JOIN
     CONTAINSTABLE(mPages, bodyText,
                    'dog') AS KEY_TBL
     ON mPages.pageID = KEY_TBL.[KEY]
ORDER BY KEY_TBL.RANK DESC;

Error:

Msg 245, Level 16, State 1, Line 2
Conversion failed when converting the nvarchar value 'About' to data type int.

The "About" value is in a column called pagename . I don't understand how to get this error to go away.

Any help?

Answer 1

It's probably complaining about this line:

ON mPages.pageID = KEY_TBL.[KEY]

Assuming pageID is an int , it will try to convert the key to an int so the columns can be compared. The conversion is not going as planned.
