SQLite with strftime('%w', ...) not giving expected results -


i need determine if particular date sunday, find date following sunday. using strftime function below check day of week, case statement not evaluate properly. example 2014-03-09 (iso format) sunday. have expected following sqlite case statement evaluate 7.

select strftime('%w', date('2014-03-09'))   , case when strftime('%w', date('2014-03-09')) = 0   7  else 0 end

generates

0|0    <-- why isn't 0|7?

what missing?

my version of sqlite is

sqlite 3.7.11 2012-03-20 11:35:50 00bb9c9ce4f465e6ac321ced2a9d0062dc364669

in query, you're comparing string integer, evaluate false. try comparing string:

case when strftime('%w', date('2014-03-09')) = '0'
