Hello dear Derby community! Very stupid question but as I newcomer from MySQL (MyISAM) I am wondering how to delete table that has references to another table?
Table *business_objects* refers to table* users*. Vice versa table* users*referes to *business_objects*. create table business_objects ( boid int not null generated always as identity, constraint pk_boid primary key (boid) ); create table users ( username varchar(60) not null, boid int not null, constraint pk_username primary key (username) ); alter table business_objects add constraint fk_created_by foreign key (created_by) references users (username); alter table users add constraint fk_boid foreign key (boid) references business_objects (boid); Dropping table *users* as first is denied because of existing reference from table *business_objects*: An error occurred when executing the SQL command: drop table users Operation 'DROP CONSTRAINT' cannot be performed on object 'PK_USERNAME' because CONSTRAINT 'FK_CREATED_BY' is dependent on that object. [SQL State=X0Y25, DB Errorcode=-1] But dropping table *businness *as first is also denied because of existing reference from table users with similar error. *So only option is delete these interrelated tables at the same time -- but how? *I tried to drop them in transaction but still the same as above. Thanks a lot! Libor
