sql server - SqlServer Select Distinct Using Single Column -


i have column contains server in action happened country. so, example, column 'source' contain 'server001[en-us]'. need distinct country codes listed.

id  source              status ============================== 1   server001[en-us]    3 2   server002[de-ch]    3 3   server005[en-us]    1 4   server001[tr-tr]    3

the ideal query output

en-us de-ch tr-tr

can this?

you need play substring , charindex. charindex give location of string within column , substring pretty obvious.

i did not test this, should trick:

select distinct substring(source      , charindex('[', source)      , charindex(']', source) - charindex('[', source))      );
