sql - Custom Result Order using UNION - TSQL -

-

i have simple task in need select rows particular field value of 1 first, value of 2 , other rows value of 0.

i using join items member of category. thought performing 3 selects , using union combine results in correct order, wrong :)

my sql follows:

select * tblcompanycategory  inner join tblcompany on tblcompany.idcompany = tblcompanycategory.idcompany tblcompanycategory.idcategory = @category , tblcompany.intpremium = 1  union  select * tblcompanycategory  inner join tblcompany on tblcompany.idcompany = tblcompanycategory.idcompany tblcompanycategory.idcategory = @category , tblcompany.intpremium = 2 union  select * tblcompanycategory  inner join tblcompany on tblcompany.idcompany = tblcompanycategory.idcompany tblcompanycategory.idcategory = @category , tblcompany.intpremium = 0

my results not come out ordered 1, 2 , 0.. doing wrong here??

* solution * guys. below final sql using.

select * tblcompanycategory      inner join tblcompany     on tblcompany.idcompany = tblcompanycategory.idcompany     tblcompanycategory.idcategory = @category      order case tblcompany.intpremium when 1 0 when 2 1 when 0 2 end

the union statement, set operators, agnostic when comes ordering data.

what can do, however, run 1 select statement carefully-crafted order statement, such as:

... order case tblcompany.intpremium when 1 0 when 2 1 when 0 2 end

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...
