SQL Async Multiple Queries Combine Results — Maximum Results (Top XYZ)

Question

I have a search function set up, where I run multiple queries simultaneously. The top 1000 results of each query are written to a table. (These run async--I am just leaving out

Answer 1

If you setup your result table with an identity column you can achieve your goal using this query (let 'counter' be that column. don't forget to put an index on it)

declare @remaining int
select @remaining = 1000 - (max(counter) - min(counter) + 1) from result
if @result>0
  insert into Result (Text) select top (@remaining) Text from MyTable

Also, if you have a list of table names, you can use a while loop and exit if @result is 0.
