Difference between timestamps will give
you an interval. So the LHS of “>” is interval and hence the RHS
should be an interval too. You should not be converting the right hand side
value to Timestamp. What is the “double” value you are calculating?
Is it in minutes, hours or days? I am not a Java expert, but the effective
query should look as follows delete from concurrent_user where (current_timestamp
– concurrent_user.time_stamp) > interval ‘5 minutes’; -Chandu From:
pgsql-general-owner@xxxxxxxxxxxxxx [mailto:pgsql-general-owner@xxxxxxxxxxxxxx] On Behalf Of kapil.munish@xxxxxxxxx Hi Everyone, I have a table named concurrent_user which has a column
time_stamp. The column stores the timestamp for the latest entered record. My query finds the difference of the timestamp from the
current time, if the value is larger than 5 minutes then the latest entered
record in the table is assigned to a new user if he tries through the
application else he is displayed an error message. The thing worked fine while the database was on Oracle but
since migrating it to postgres it is not able to handle the conversion. The query is something like : DELETE from CONCURRENT_USER WHERE (now() -
CONCURRENT_USER.TIME_STAMP) > ? Here the calculated value in ‘?’ is not
supported by the postgres as it was set as a double. I tried to cast it to a timestamp by using Timestamp
timestamp = new
Timestamp((java.sql.Date(rs.getTimestamp(time_stamp)).getTime()); But then it started to give : ...... <Exception Message> : ERROR: invalid input
