Обсуждение: Build from file syntax troublem.

Hello, All!

I have to fiil datebase from file contains strings alike such:

CREATE SEQUENCE public.blacklist_id_seq INCREMENT 1 MINVALUE 1
MAXVALUE2147483647 CACHE 1;

and

CREATE FUNCTION public.from_days(int4) RETURNS timestamp AS '
    select ''0000-01-02''::timestamp + ($1 || '' days'')::interval as result
'  LANGUAGE 'sql' VOLATILE;

The parser abuse  that
'parse error at or near  '"."  ',
'parse error at or near  "public'"  ',
'parse error at or near  "#'"  '.

PostgeSQL version is 7.2.3.

I've nowhere found isuch syntax in the net (I mean with dot -
'public.funcname(...)').

There is  plpgsql only in the database;
When  I try
./createlang  -dbname=mydb sql
it says "unsupported language".
But SELECT * FROM pg_language
show that it's present.

Where I'm wrong?

Successes & good luck for all,
Igor

You need 7.3 or later to deal with schema-aware commands.

Hello Tom,

Thank you very much for such fast reply.

But now, after I've installed 8.0.1, it says things as examples in
little attach.
<------
Where I have to dig?.. :(

That's a plpgsql function, not an sql function.  Your other examples
look like they were taken from some other database that has different
extensions to the SQL spec than we do: there is no "varchar binary"
in Postgres, and we don't allow you to add random commas at the ends
of column lists.  PG isn't going to like '0000-00-00' for a date,
either.
