Question

I’m using MS SQL Server Management Studio R2

suppose I have a table tableX with infinite records count,
and that table has a column colX, and the there’s only 2 records in the whole table that have this colX not null,

what should the query look like?

I used

select top 10 * from tableX where colX isnot null

but it took forever executing the query

it there a way to search in the first 300 rows only?
thanks

Answer 1

Well, thanks for your help, I fixed this problem in a tricky way,

I did make a new table

Declare tempTable table(...columns...)

and then

insert into tempTable (select top 300* from tableX)

after that,

select * from tempTable where colX is not null
