sql server - How to remove duplicates of inner query that was used to remove duplicates in SQL? -


this sql server question, here tables working (note: column name name of code set):

table: code set

code_set_id  | name -------------+----------- 1            | jackets 2            | pants 3            | shirts

table: code set detail

code           | description    | code_set_id ---------------+----------------+------------ blue           | blue jacket    | 1 blue           | blue jacket    | 1 green          | green jacket   | 1 green          | green jacket   | 1 purple         | purple jacket  | 1

the query wrote finds duplicate code set codes , code set code set codes belong too. following query return 

jackets, blue,  2 jackets, green, 2

how wrap query around following query jackets?

select      bcs.name, bcsd.code, bcsd.description, count(*)      code_set_detail bcsd inner join      code_set bcs on bcsd.code_set_id = bcs.code_set_id group      bcs.name, bcsd.code, bcsd.description having      count(*) > 1

so far, i've tried using where exists, yet result set not correct.

with x (name, code, description, detailcount) (     select bcs.name, bcsd.code, bcsd.description, count(*)     code_set_detail bcsd     inner join code_set bcs      on bcsd.code_set_id = bcs.code_set_id     group bcs.name, bcsd.code, bcsd.description     having count(*) > 1 ) select distinct name x

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
