# title:        External engine trigger crashing server if table have computed field
# decription:   
#                   We use supplied UDR example which operates with TRIGGER for replication purpuses.
#                   Two databases are used here: one is 'main' (which is created by fbtest) and second
#                   is auxiliary and serves as slave (replica).
#               
#                   We create table PERSONS in both databases, its DDL is taken from examples code.
#                   This table will be normally replicated until we add COMPUTED BY field to it.
#               
#                   When such field is added and we issue INSERT command, standard exception must raise:
#                       Statement failed, SQLSTATE = 42000
#                       Execute statement error at isc_dsql_prepare :
#                       335544569 : Dynamic SQL Error
