Date math question - Mailing list pgsql-general

Hi All;

I have a table that contains 2 columns ts (a timestamp) and dursec (a float -
number of seconds)

I want to insert the following into another table:

the ts (timestamp column) and a second date which is ts + dursec

I tried these select variations with no luck:

select ts, ts + interval dursec seconds from tmp2 limit 1;

select ts, ts + 'seconds' dursec from tmp2 limit 1;



Anyone know the correct syntax for this ?


Thanks in advance
