Hello,

Two columns of a table (for the database engine “HyperSQL” within the application
“LibreOffice Base 7.1.0.3-985.1”) have got the data type “TIME”.
I would like to compute a difference for these fields.

It seems that the following SQL statement is insufficient so far.

SELECT ID, t1, t2, t2 - t1 AS duration FROM time_measurements1


I would appreciate your advices.

Would you like to point further information sources out besides query examples
which work with dates and time stamps?

Regards,
Markus
