Обсуждение: Arrays returned in a result set

David,

The 7.2 code should support arrays.

Ok, but what I really want to know is if there is *special* support for
arrays.  As far as I can tell, arrays are just strings in the result
set, with the "{value, ...}" formatting.  So do I have to write code to
parse through the string, or does the drive provide me with some kind of
convienence methods or objects?

David,

Sorry I wasn't more specific.   In 7.2 the postgres jdbc driver supports
the standard jdbc methods ResultSet.getArray() and
PreparedStatement.setArray().  I haven't used this functionality, but it
was added in 7.2.

thanks,
