Export subsets of data with date query [message #70074]

Hello

Can anyone pls tell me how to use the exp utility but with the query from a date for ex:
exp usr/pw tables=abc_tbl query="where start_date > to_date('01-JAN-2002','DD-MON-YYYY')

The above script does not work as well as various versions of it. Can you use queries with date values with this function and if not how can you get a subset of data for export with dates > x?

Thanks, Jaco

Jaco,

For every quote be it single or double you have to escape it. First question is the start_date a date column? If so:

query="where start_date > '01-JAN-2002'"

or did you try:

query="where start_date > to_date('01-JAN-2002','DD-MON-YYYY')"

Another option is to:

create table mytemp as select * from abc_tbl where start_date > to_date('01-JAN-2002','DD-MON-YYYY')

and then export mytemp.
