Oracle Conversion

Hell,

I have some view created on my Oracle database. Same thing i want to convert to SQL Server. here are the some key words used in the oracle like
sys_connect_by_path, SUBSTR,INSTR etc. could any one help me in converting the same.

CREATE DisplayResults AS

fe.vm, fe.iia,
f.lct -

when f.tspcnt > 1
then 1
else 0
end) lct,

then h.lid
else 'KKM'
end)) lct,
