How can i search for a particular date for eg: '2013-10-22' from teradata timestamp(6) field?

sel * from table A
where date = '2013-10-22';

I tried the above query which is throwing error. Please help!

You may try like this:-

sel * from table A
where date = date '2013-10-22';

Since in ANSI standard form (must be preceded by the keyword DATE)

Check out this

Something like this:

where YourTimestampField >= {d '2013-10-22'}
and YourTimestampField < {d '2013-10-23'}

And more formally:

select * 
from table A
where cast(timestamp_column as date) = date '2013-10-22';

I'm guessing that you were just showing an example, because I don't think you can have a column named date; it's a reserved word. The keyword "date" above is how you specific an ANSI date constant and is not related to the "date" function.
