I have created one temp table and inserted 10 records and I have written one query which checks 3rd highest salary. This query is having sub query. I want to know which query executes first inner query or outer query? kindly check the query which is written below.
CREATE TABLE #tmpTbl ( id int, sal money ) insert into #tmpTbl values('1','12000') insert into #tmpTbl values('1','22000') insert into #tmpTbl values('1','50000') insert into #tmpTbl values('1','100000') insert into #tmpTbl values('1','100') insert into #tmpTbl values('1','5000') insert into #tmpTbl values('1','15000') insert into #tmpTbl values('1','18000') insert into #tmpTbl values('1','19000') insert into #tmpTbl values('1','21000') SELECT * FROM #tmpTbl order by sal asc SELECT DISTINCT sal FROM #tmpTbl t1 WHERE 3 = (SELECT COUNT(DISTINCT SAL) FROM #tmpTbl t2 WHERE t1.SAL <= t2.SAL)
kindly run both the query, first query will give you salary in ascending order and second will give you 22000.00.
Which runs first: the outer query or the inner query?
