Hi,

I have Postgres 7.0, and I created a table

table
---------
...
borrow timestamp
return timestamp

Now, I thought timestamp is in sec eg; 35434434, but in PostgreSQL, it
shows up as datetime datatype eg; 2000-06-07 17:00:05-07.

I was wondering is this format a correct one for timestamp, or is it a
bug?  Abd if I want to show the time, each retrieval I have to chop of
the '-07' timezone at the end.  Is there a way to avoid this being show
up in Postgres?

Thanks.


- Bernie

You might want to check out the date/time and formatting functions at

Hai All,

           I have been using Mysql in which I used unix_timestamp() function 
to retrieve the time using the queries. As it gives time in seconds the life 
is easy to store it in database and to compare with the other times. But now I 
am moving to PostgreSQL in which there is a function current_timestamp to 
retrieve time, but now it became hard for me to store it in database in the 
string format and to compare it with other times again.

               Is there any function in PostgreSQL which returns time in 
seconds like unix_timestamp() in Mysql. Please suggest me some ways to get rid 
of this problem.

            My email: kumar@cc.usu.edu .
Thank you All,
 Kumar.

What is the specific problem you're having?  Do you have an example that
illustrates it?

In general, I don't know why you'd want to store the timestamp as a string
rather than a timestamp.

I am use PostgreSQL 7.2.1 in Redhat Linux 7.2
Java 1.4.x

When I do JDBC

String sql = "SELECT datetime_column FROM mytable";
....

Timestamp ts = resultSet.getTimestamp(2);

If the timestamp return format like

2003-07-15 13:20:00.20+00

then is OK. But if timestamp return like

2003-07-15 13:20:00.421+00

Then I got SQLException

Bad Timestamp Format at 23 in 2003-07-14 14:45:00.421+00

What is 23?
How do I resolve this problem?

Thank Q!

Raymond,

Upgrade to the latest stable driver.  You can download it from 
jdbc.postgresql.org.
