Relation does not exist

От

Дата:
Hi everyone.

I am new to this list, and a real novice with databases.

A while back I created a database using postgres 7.03 in Mandrake 7.2.
It is a catalog for all my books.

Although not really knowing what I was doing, I have recently upgraded
it to 7.2 along with Mandrake 8.2.  I did a dump_all from 7.03, and
then read it all in to psql in 7.2.

When I try to view the database, everything is there and looks OK.  But
if I try to insert a new entry I get the following error:

ERROR: Relation "books_bookid_seq" does not exist.

Using phpPgadmin shows:

Field    Type   Length  Not Null   Default
BookId   Int4   4       Yes        nextval('Books_BookID_seq'::text)

What do I need to do?

Brian

in your queries you have to refer to it with propercase and enclose in "
quotes

so books_bookid_seq will cause the error

"Books_BookID_seq" will be ok...

I'm also a novice... I don't know what you are doing but here is an example
of properly referring to a column called Cars in a table called Customers
like this

"Customers"."Cars"

if you run a windows machine connecting to your pg machine, nice easy
interface is PGExplorer or PGAdmin. They show you this kind of thing to
some extent and PGExplorer helps write the syntax to some extent.

It's been awhile, but I think that 7.0's nextval() would take the given
string literally, while later versions follow the downcase-unless-quoted
rule that applies to names in normal query contexts.  So if you had
    nextval('Books_BookID_seq')
before, you now need
    nextval('"Books_BookID_seq"')

Or you could recreate the sequence with an all-lower-case name...

            regards, tom lane

Thanks Tom, April for your help.

As soon as I get the chance in the next few days I will look into
your suggestions.

Brian.

Yes, putting the extra " in as Tom suggested has fixed it.

Thankyou.
