I created this table:
Column | Type | Modifiers
------------+------------------------+------------------------
first_name | character varying(20) |
last_name | character varying(30) |
w_number | character varying(9) |
alert | character varying(200) |
post_date | date |
id | integer | not null
Indexes:
"alert_list_pkey" PRIMARY KEY, btree (id)
------------+------------------------+------------------------
first_name | character varying(20) |
last_name | character varying(30) |
w_number | character varying(9) |
alert | character varying(200) |
post_date | date |
id | integer | not null
Indexes:
"alert_list_pkey" PRIMARY KEY, btree (id)
I get this error when I run the insert a listed below. The insert does not have an entry for the primary key "id" since I thought it updates automatically:
Warning: pg_query() [function.pg-query]: Query failed: ERROR: null value in column "id" violates not-null constraint
$sql = "INSERT INTO alert_list (
w_number,
first_name,
last_name,
alert,
post_date
)
VALUES (
'$txtStudentNumber',
'$txtStudentFirstName',
'$txtStudentLastName',
'$txtStudentAlert',
'now()'
)";
w_number,
first_name,
last_name,
alert,
post_date
)
VALUES (
'$txtStudentNumber',
'$txtStudentFirstName',
'$txtStudentLastName',
'$txtStudentAlert',
'now()'
)";
How do I do an insert on this table and have the primary key "id" update with the record?
thanks
Marc
