Actually i have search query like below

SELECT top 100 ID, COMPANY,

ADDRESS, Area, POSTALCODE, PROVINCE, PHONE1,

FAX, EMAIL, WEBSITE , city, lat, lon,FLAG, DBO.DISTANCE(LAT,LON,@LATITUDE,@LONGITUDE) AS DIST

FROM vwSearchResult

WHERE

comp_kws like '%' + @qry + '%' AND

locStr like '%' + @loc + '%'

ORDER BY DIST

This shows me alot of records....some have FLAG=0 and some have FLAG=1.

lets say there is 100 records where FLAG =1.

Now i want to show only 3 of them at the top and then show all other records having FLAG = 0...

hope this will clear to u!!

Ugh! A FLAG "field" isn't very useful. It's virtually useless to index them because of the very low number of unique values they have. They're also virtually useless because they only tell you that, in this case, the item is "paid"... it doesn't tell you when it was paid and problems like this one become a real pain.

My suggestion would be to change your FLAG "field" to a "DatePaid" column and then this problem becomes almost child's play. If you can't change the column, then you really need to tell us what you think the "TOP 3" and "TOP 100" are according to the sort order of the columns you have. If the answer is "it doesn't matter", then I have to ask "then why bother" for this code? What is the business reason for this code?

After alot of googling i found solution like this

SELECT top 100 ID, COMPANY,

ADDRESS, Area, POSTALCODE, PROVINCE, PHONE1,

FAX, EMAIL, WEBSITE , city, lat, lon, DBO.DISTANCE(LAT,LON,@LATITUDE,@LONGITUDE) AS DIST

FROM vwSearchResult

WHERE

comp_kws like '%'+@qry+'%'

AND ID IN (

SELECT TOP 3 ID

FROM vwSearchResult

WHERE comp_kws like '%'+@qry+ '%' AND FLAG = 1 )

OR

ID IN (

SELECT TOP 100 ID

FROM vwSearchResult

WHERE comp_kws like '%'+@qry+ '%' AND FLAG = 0)

order by FLAG DESC

Heh... nicely done but it's just as I said... there's no significance to which rows have been returned for either set. So, now my curiosity is really up... If you don't mind me asking, what's the business reason for such a query?

As i mentioned earlier,i want to show top 3 paid companies(paid companies are more than 3) on the top of my application display page and then show unpaid companies below

Jeff Moden SSC Guru Points: 1004356 More actions · Answer 8

Thanks... I get and got that. What I'm curious about is why you don't care with 3 companies paid and why you don't care which companies didn't. You'd think that there would be something like the top 3 companies that paid on time or list the top 100 companies by how much they owe. The totally random of the current selections make no sense to me.

Lemme guess... you're just following someone else's instructions and really don't know the business reason for this query... correct?

Top 3 by what criteria? Your query currently selects 3 companies with flag 1 (any three) with no other ordering. You could even get a different 3 every time you run the query.

That's what I thought.

Just so you know, TOP in code has no sort-order implications without a "correct" ORDER BY and the ORDER BY on the FLAG column isn't what I'd consider a "correct" ORDER BY for the task at hand. You're not actually getting the "top" 3 companies that paid... you're getting "any" 3 companies that paid. You might want to ask your project manager if that's what they really intended. It's your neck if it's wrong and I'm trying to help you keep your neck out of the proverbial noose.

Based on the fact that you ignore multiple requests for information and do not provide anything like enough detail while asking your questions, I am not surprised.
