I know I can convert SQL timestamp to unix timestamp, using the following way.
SELECT extract(epoch FROM now());
Now, I have a stored procedure function, which will directly return a table row
to the caller. One of the row field is "timestamp" type.
In my application, I am using libpq. I wish to use libpq functions (or any
c/c++ function), to convert "2010-01-11 13:10:55.283" into unix timestamp. Off
course, I can create another stored procedure named
SQLTimestamp2UnixTimestamp
SELECT extract(epoch FROM $1);
But I just wish to accomplish this task with a single c/c++ function call,
without involving stored procedure.
Any suggestion? Thanks!
Thanks and Regards
