I do a PreparedStatement and setTimestamp() to do the select.
The Timestamp value is converted into a String in the JDBC code.
This may not be a JDBC problem. I can not select by a datetime field
in psql all the time. It seems if the milliseconds are below some
value it works and if above not. .62 worked for me but .71 did not.
I did a copy and paste of the datetime value to get it right:
select * from table_a;
| fld1
---------------------------
|2000-10-24 10:15:01.71-04|
select * from table_a where fld1 = '2000-10-24 10:15:01.71';
0 records found
I had to make a change to the JDBC code to even get the .62 select to
work. The Timestamp toString() method gives a 3 digit millisecond
value and Postgres seems to not want the leading zero (ie: .62 viz
.062).
I will try these with query=1 in pg_options to get the query.
