Обсуждение: stupid insert error

I guess I'm too stupid to see the error, but I don't understand why
the following fails.


insert into person3 (asuid, fname, lname, addedby, addedon,
slopbucket) values ("123455", "name", "name", "entered", "12/12/2004", NULL);
ERROR:  column "123455" does not exist

is the double quote byting me?

String constants use single quotes (or dollar quotes as of 8.0);
double-quoted strings are interpreted as identifiers.  See "Lexical
Structure" in the "SQL Syntax" chapter of the documentation:

http://www.postgresql.org/docs/8.0/static/sql-syntax.html#SQL-SYNTAX-LEXICAL

If I'm not mistaken, this distinction is defined in the SQL standard.

Try single quotes (') instead of double-quotes (").

You want single quotes not double quotes.  Double quotes are for
identifiers, single quotes are for literals.  See
http://www.postgresql.org/docs/8.0/static/sql-syntax.html#SQL-SYNTAX-IDENTIFIERS
and the following section.

David Bear,您好！

    yes.of course.
    you should insert the record like this:
    insert into person3 (asuid, fname, lname, addedby, addedon,
    slopbucket) values ('123455', 'name', 'name', 'entered', '12/12/2004', '');
