Hi Krishane,
* SQL Server often auto-generates constraint names, while PostgreSQL
typically requires explicit
names.
You will need to give more detail on above as:
create table constraint_test (id integer primary key, fld_1 varchar,
fld_2 varchar check (fld_2 != ''), UNIQUE(fld_1, fld_2));
constraint_test
Table "public.constraint_test"
Column | Type | Collation | Nullable | Default
--------+-------------------+-----------+----------+---------
id | integer | | not null |
fld_1 | character varying | | |
fld_2 | character varying | | |
Indexes:
"constraint_test_pkey" PRIMARY KEY, btree (id)
"constraint_test_fld_1_fld_2_key" UNIQUE CONSTRAINT, btree (fld_1,
fld_2)
Check constraints:
"constraint_test_fld_2_check" CHECK (fld_2::text <> ''::text)
