oracle - trigger is giving ORA-04091 error -


i have after insert trigger on table tbl_campboss_report , giving me tbl_campboss_report mutating, trigger/function may not see it

this trigger:

begin update tbl_campboss_report c set c.units=(select b.units tbl_campboss_master b b.details=:new.details);   end;

can me on this?
in advance

consider changing trigger before insert. don't need write update statement in trigger. assign value required column.

:new.units = <value query>;
