I have a string column very long with multiple underscores in between. My requirement is to only select those columns where the string between second and third underscore matches a certain criteria.
For instances lets say The Compare Values is "RIC" AND I have a row value DMV1004/343M.TR3432_PLC089_RIC_9843CL
Here i need to check if the string between the 2nd and 3rd underscore is RIC which in this case is true.So i would need to compare and if true insert that value. How would i do that efficiently? thnx.

Not saying how efficient it is but this may work:

declare @TestStr varchar(128) = 'DMV1004/343M.TR3432_PLC089_RIC_9843CL';

select @TestStr where @TestStr like '%[_]%[_]RIC[_]%';

set @TestStr = 'DMV1004/343M.TR3432_PLC089_RIC1_9843CL';

select @TestStr where @TestStr like '%[_]%[_]RIC[_]%';

Thanks Lynn, How would i make this dynamic...lets say if the search criteria for the string was between 3 and 4 instead of 2 and 3 based on another parameter. how would this work..i may have to go that route ...cause based on a client the search criteria varies and there are mulitple values to loook for ..like RIC,FED,SRP...u get the idea ...thanks again.

declare @TestStr varchar(128) = 'DMV1004/343M.TR3432_PLC089_RIC_9843CL';

select @TestStr

from dbo.DelimitedSplit8K(@TestStr,'_')

where ItemNumber = 3

and Item = 'RIC'

You can get DelimitedSplit8K from here : http://www.sqlservercentral.com/articles/72993/
