You cannot create a table that references a table that does not yet exist. To create two or more tables that reference each other, use create schema.
A schema is a collection of objects owned by a particular user, and the permissions associated with those objects. If any of the statements within a create schema statement fail, the entire command is rolled back as a unit, and none of the commands take effect.
The create schema syntax is:
create schema authorization authorization name create_object_statement [create_object_statement ...] [permission_statement ...]
For example:
create schema authorization dbo create table list1 (col_a char(10) primary key, col_b char(10) null references list2(col_A)) create table list2 (col_A char(10) primary key, col_B char(10) null references list1(col_a))
