I am trying to query multiple columns in multiple tables.   I need to weigh certain columns in the results.  My current code looks as follows:
"select Key_Tbl.[key], tblBlogThreads.BlogThreadNum,  tblBlogThreads.Body,tblBlogThreads.PublishDate, tblBlogThreads.Title, tblBlogThreads.Teaser, tblBlogThreads.MetaKeywords,  [rank] from freetexttable(tblBlogThreads, body, '" & tstr & "' ) AS Key_Tbl  INNER JOIN tblBlogThreads ON tblBlogThreads.BlogthreadID = Key_Tbl.[key] order by [rank] desc"

The problem is i need to search in columns tblBlogThreads.Title,  tblBlogThreads, Keywords, and tblBlogThreads.Body, and weigh them in that order.

The ranks returned are 1-1000, therefore match by title will have high rank, then keywords, then body.  I forgot to trim duplicates. this one fixes it

select
Key_Tbl.[key], tblBlogThreads.BlogThreadNum,  
tblBlogThreads.Body,tblBlogThreads.PublishDate,
tblBlogThreads.Title,
tblBlogThreads.Teaser,
tblBlogThreads.MetaKeywords,  
[rank]
from
(select [key], max(rank) as rank from
(select [key], rank + 2000 as rank from freetexttable(tblBlogThreads, title, '" & tstr & "' )
 union all
 select [key], rank + 1000 from freetexttable(tblBlogThreads, keywords, '" & tstr & "' )
 union all
 select [key], rank from freetexttable(tblBlogThreads, body, '" & tstr & "' )
) tbl1
group by [key]) AS Key_Tbl
INNER JOIN tblBlogThreads ON tblBlogThreads.BlogthreadID = Key_Tbl.[key]
order by [rank] desc

Thanks!

these look good but there's a syntax error in there somewhere- getting error near a space, near a space and near a ).
Looking into it...

That was meant to include a start " and an end " to be assigned to a string from ASP.NET.  That's why there are two
" & tstr & "
bits in the middle

It does not run as is and will cause an error from Query Analyzer!
But I think you get the idea.

How would this be represented as a stored procedure where tsq is the parameter (@tsq)

select 
Key_Tbl.[key], tblBlogThreads.BlogThreadNum,  
tblBlogThreads.Body,tblBlogThreads.PublishDate, 
tblBlogThreads.Title, 
tblBlogThreads.Teaser, 
tblBlogThreads.MetaKeywords,  
[rank] 
from
(select [key], max(rank) as rank from
(select [key], rank + 2000 as rank from freetexttable(tblBlogThreads, title, '" & tstr & "' )
 union all
 select [key], rank + 1000 from freetexttable(tblBlogThreads, keywords, '" & tstr & "' )
 union all
 select [key], rank from freetexttable(tblBlogThreads, body, '" & tstr & "' )
) tbl1
group by [key]) AS Key_Tbl
INNER JOIN tblBlogThreads ON tblBlogThreads.BlogthreadID = Key_Tbl.[key] 
order by [rank] desc
