hello,
i'm having trouble inserting values into my database. I want create a table that will auto-increment everytime i insert a new row. this is the command i used to create myTable:
[code]
create table myTable (id serial, names text);
[code]
now when i try to insert a new record by doing:
Code:
insert into myTable values("myName");
i get an error saying it can't be parsed. but when i do:
Code:
insert into myTable values(0, "myName");
if works fine, but my question is----is there a way i can create a table that every time i create do an insert it will increment my id field, for example
Code:
insert into myTable values("myName");
i want my database to increment the id column by one and insert myName into my database.
Note that if you do NOT specify col names, values will be inserted in in the order that the cols exist on the table... this is not reqd to be the order you used in the CREATE statement (although it usually is).
Basically, NEVER assume ... always specify. You can however skip cols that you do not supply values for.

Originally posted by djgerbavore that worked fine, thanks, but why do you think i have to put names in parthenise?
Because string can be everything. Imagine this:
INSERT INTO table VALUES ("one, two, three");
Without quotes it will be used as separate parameters. Note that you should in fact quote all values.
Originally posted by djgerbavore I mean the actually column named name.
insert into table myTable (name) values("foo");
So the database knows which column to insert the
value to ... you need to a) either specify ALL values
(including the WORD default for the automatic columns)
or b) tell it which columns you want to populate.
