I am trying to run a comparison on datetime field. With timezone, the value gets treated as a string.
DB: MS SQL
MyTable.find_by_sql("select * from my_table where my_date > '2012-02-15 16:07:32 UTC'")
ActiveRecord::StatementInvalid: TinyTds::Error: Conversion failed when converting date and/or time from character string.
If I remove the timezone, it returns results.
MyTable.find_by_sql("select * from my_table where my_date > '2012-02-15 16:07:32'")
How can I do this comparison with '2012-02-15 16:07:32 UTC'
? I need to use find_by_sql (fetching data from a different DB. Can't use the rails sql queries). Thanks!
You can parse the datetime using:
a_datetime = DateTime.strptime('2012-02-15 16:07:32 UTC', '%Y-%m-%d %H:%M:%S %Z')
then format the date using something like:
datetime_str = a_datetime.strftime('%Y-%m-%d %H:%M:%S')
and do your find with:
MyTable.find_by_sql("select * from my_table where my_date > '#{datetime_str}'")
I haven't tested any of this but should work.
I'm guessing you're calling to_s
on a datetime field resulting in '2012-02-15 16:07:32 UTC'?
Try calling to_s(:db)
instead for the database-friendly version.
