             Summary: Problem with schema name starting with number followed by a dot
                 Key: DERBY-6918
                 URL: https://issues.apache.org/jira/browse/DERBY-6918
             Project: Derby
          Issue Type: Bug
          Components: SQL
    Affects Versions: 10.13.1.1
            Reporter: Hooman Valibeigi


It seems that there is a problem with schema names that start with a number followed by a dot.
Please take a look at the following script. Everything works fine but the last line which is a delete statement. Note that having the foreign key constraints was necessary to make it reproduce the problem.

create schema "1.a";

create table "1.a"."role"
(
"id" integer generated always as identity,
"name" varchar(255) not null
);

alter table "1.a"."role" add constraint "role_pk"
primary key ("id");

create table "1.a"."user"
(
"id" integer generated always as identity,
"name" varchar(255) not null
);

alter table "1.a"."user" add constraint "user_pk"
primary key ("id");

create table "1.a"."user_role"
(
"role" integer not null,
"user" integer not null
);

alter table "1.a"."user_role" add constraint "user_role_fk1"
foreign key ("role")
references "1.a"."role" ("id")
on delete cascade;

alter table "1.a"."user_role" add constraint "user_role_fk2"
foreign key ("user")
references "1.a"."user" ("id")
on delete cascade;

alter table "1.a"."user_role" add constraint "user_role_u1"
unique ("user", "role");

insert into "1.a"."role" ("name") values ('r1');
insert into "1.a"."user" ("name") values ('u1');
insert into "1.a"."user_role" ("role","user") values (1,1);

select * from "1.a"."user";

delete from "1.a"."user";

Last delete statement fails. The error is:
Schema '1' does not exist [SQL State=42Y07, DB Errorcode=20000]
