Thread: confused newbie (to pg not db's)

I have setup a database that I am the owner of, and I am trying to setup
constraints and it doesn't seem to be working

Example

- Table: public."Invoice_Header"

-- DROP TABLE public."Invoice_Header";

CREATE TABLE public."Invoice_Header"
( "Inv_ID" int4 NOT NULL DEFAULT nextval('public."Invoice
Header_ID_seq"'::text), "client_ID" int2 NOT NULL, payable_recievable varchar(5), "date_CREATED" date, "AMOUNT" money,
amount_paidmoney, date_paid date
 
) WITH OIDS;

I am trying to make Inv_ID a primary key as follows

alter table Invoice_Header ADD CONSTRAINT PK_inv PRIMARY KEY (Inv_ID)

which runs without error, but nothing changes

this is from psql with PG 7.3.2

any help appreciated

I think you have tables named "Invoice_Header" and "invoice_header",
and the latter table is what's getting affected by your ALTER.  If you
are going to use mixed-case names then you have to be consistent about
double-quoting them all the time.

I worked out what was happening - I was missing the ;

Not helped by pgaccess and pgadmin not working right in different ways
