Обсуждение: references to variable in another schema

Hi folks:

I wanted to put a reference on a table in the public schema that
references a column in a table in another schema. I tried:

create table cellphone(emplid integer not null references
admin.tbl_employee.employee_id);

ERROR:  cross-database references are not implemented:
"admin.tbl_employee.employee_id"

But these are within one database. Is there a way to do this or have I
gotten my syntax messed up?

The hierarchy in postgresql is Server->database->schema->table->column

How as "admin" created?  By using "create schema admin" or something else?

Should be

create table cellphone(emplid integer not null
    references admin.tbl_employee(employee_id));

Or, if employee_id is the declared primary key of tbl_employee, you can
just say

create table cellphone(emplid integer not null
    references admin.tbl_employee);

Thanks, Tom.  I was woefully off-target.

Works like a charm. Thanks Tom & Sean for the quick response!
