Recently I got unique key violations during insert attempts on a piece of code that
used to work (what can go bad, will go bad). I found that the offending field - was
actually created by a generator. For some reason the generator returned values that
where already in the database.
how can I display the current value of the generator?
how can I adjust the value of the generator?
See the example (table name is SD_LOAD, generator name is GEN_SD_LOAD).
You cannot modify the value of the generator inside of a trigger or stored
procedure. You only can call the gen_id() function to increment the value in a
generator. The SET GENERATOR command will only work outside of a stored procedure
SELECT DISTINCT(GEN_ID(gen_sd_load, 0))FROM sd_load
set GENERATOR gen_sd_load to 2021819
