Hi Zoran!
I suggest you to make unique key on
"T_ORDERCUSTOMER".OrderId
and
T_ORDERVEHICLE".OrderId
and you will get an exception when the secound row is inserted into the tables.
Maybe this helps to find out where is the problem.

Read only, read commited transactions can be long running, but read only

Hi Karol!
Yes, but if you do lock in MEETINGS_UQ_BI the lock will hold only while the
trigger runs in autonomous transaction. Depending on the business logic it can
be much more shorter (some millisecounds) than locking in „parent” transaction
and hold it for minutes or more waiting for user
.

Hi Karol!
Create a (reserved_dates) table with date field, and make that field unique..
When a user inserts a date into the reservation table a trigger immadiate
inserts this date to the reserved_dates table too. Then the unique key will
stop secound insert instead of the first transaction is

If i understood well, you need this (tested on Fb2.5.8):
select * from table where field = ascii_char(3) || ascii_char(1);
or
select * from table where ascii_val(substring(field from 1 for 1) = 3 and
ascii_val(substring(field from 2 for 1) = 1;

Hi!
Maybe the select starts the garbage collection, and it slows down it. When you
run backup without -g it does the garbage collection too, so could fix the
problem. (Are you running it with / without -g?)
