how perform if...then in sql select statement?

for example:

select if(obsolete = 'n' or instock = 'y' ? 1 : 0) saleable, * product

the case statement closest if in sql , supported on versions of sql server

select cast(              case                    when obsolete = 'n' or instock = 'y'                       1                    else 0               end bit) saleable, *  product

you need cast if want result boolean value, if happy int, works: 

select case              when obsolete = 'n' or instock = 'y'                 1                 else 0         end saleable, *  product

case statements can embedded in other case statements , included in aggregates.

sql server denali (sql server 2012) adds iif statement available in access: (pointed out martin smith)

select iif(obsolete = 'n' or instock = 'y', 1, 0) saleable, * product

i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
