Try this:
update NewsSYSNewsTags
Set NewsSYSNewsTags.RankInCaption = 5 
From NewsSYSNewsTags, NewsSYSTags, News
where NewsSYSNewsTags.NewsSYSTagsID  = NewsSYSTags.NewsSYSTagsID
and News.NewsID = NewsSYSNewsTags.NewsID
and IndexOf(rtrim(NewsSYSTags.TagTitle), News.NewsCaptionAR) > 0 -- Tag appears in Caption
and News.NewsID = 1011 --Look for specific news

Open in new window

Harish, I think you meant CHARINDEX versus INDEXOF above.
CHARINDEX: http://technet.microsoft.com/en-us/library/ms186323.aspx

Note: you may get a few false positives if your tag is a common part of other words.  For example, suppose your tag is "bask" then it will match to "basket" and "basketball."  As another aside, if you enabled full-text search on SQL Server, you may be able to use those functions to assist you here.

Anyway, I just wanted to assist with the correct T-SQL function to find index of character/string as INDEXOF is not valid for Microsoft SQL Server.  You need CHARINDEX, PATINDEX, or full-text search like CONTAINS.

I hope that helps!
