Andrew McIntyre commented on DERBY-1854:
----------------------------------------

Should this also be ported to 10.0, since the fix for DERBY-655 which caused this regression was also ported there?

> Running the following short SQL script from ij will cause an error "ERROR XSAI2: The conglomerate (817) requested does not exist.".  It appears that the SYSCS_COMPRESS_TABLE function corrupts tables that have a single column which is both a primary key and a foreign key.
> connect 'jdbc:derby:/testdb;create=true';
> CREATE TABLE users (
>  user_id INT NOT NULL GENERATED BY DEFAULT AS IDENTITY,
>  user_login VARCHAR(255) NOT NULL,
>  PRIMARY KEY (user_id));
> CREATE TABLE admins (
>  user_id INT NOT NULL,
>  PRIMARY KEY (user_id),
>  CONSTRAINT admin_uid_fk FOREIGN KEY (user_id) REFERENCES users (user_id));
>  
> INSERT INTO users (user_login) VALUES('TEST1');
> INSERT INTO admins VALUES (VALUES IDENTITY_VAL_LOCAL());
> CALL SYSCS_UTIL.SYSCS_COMPRESS_TABLE('APP', 'ADMINS', 0);
> SELECT * from admins;
