Oracle to SQL Server: Month + Year where clause -


i have oracle query goes follow:

select ... ... ...     , to_char(a.bill_date, 'mmyyyy') = '072017'     ... order ... 

in sql server, have month() , year() functions.

select ... ... ...     , month(a.bill_date) = month(getdate())     , year(a.bill_date) =  year(getdate())     ... order ... 

is there allows me apply month-year constraint oracle to_char through single step? have make parameterized , maintain compatibility both databases through common interface. now, 1 require 2 parameters , other one.

i think closest thing oracle's to_char function in sql server convert. convert see no option request year , month. rather, need accept @ least day well, , possibly timestamp in addition this.

convert accepts date format mask parameter third argument. 112 mask returns date in following format:

yyyymmdd 

so date in question return this:

201707dd 

where have left dd undefined don't know day given record might have. can close want taking left 6 characters of output, e.g.

where ... ,     left(convert(varchar, a.bill_date, 112), 6) = '201707'
