hello everybody!!

i am trying to emulate mysql enum's by creating another table, putting
in the allowed values for the enum, and creating a REFERENCE CONSTRAINT
to it. So, i have the created reference table:

mod=# \d qp_qualchoice_goodchoice_constraint_table;
Table "mod_schema.qp_qualchoice_goodchoice_constraint_table"
Column | Type | Modifiers
------------+----------------------+-----------
goodChoice | character varying(3) | not null
Indexes:
"qp_qualchoice_goodchoice_constraint_table_pkey" PRIMARY KEY, btree
("goodChoice")

mod=# select * from qp_qualchoice_goodchoice_constraint_table;
goodChoice
------------
n
y
(2 rows)

mod=# \q

but when i try to do the following table which references it........

--
-- Table structure for table qp_qualchoice
--

CREATE TABLE qp_qualchoice (
"qid" int2 NOT NULL default '0',
"choiceid" int2 NOT NULL default '0',
"goodChoice" varchar CONSTRAINT qp_qualchoice_goodChoice_constraint
REFERENCES qp_qualchoice_goodChoice_constraint_table (goodChoice)
default 'n',
"choiceText" text NOT NULL,
"addate" date default NULL,
"moddate" date default NULL,
"battery_id" varchar(15) default 'klpt4'
) ;

i get this error:

psql:pg_sql.sql:44: ERROR: column "goodchoice" referenced in foreign
key constraint does not exist

BUT THAT COLUMN EXISTS, so where is my mistake?

thanks to all.....

joseph.
