PostgreSQL insert query

Question

I try to insert a single line to log table, but it throws an error message . ><

The log table structure is like this:

no         integer  NOT NULL nextval('log_no_seq'::regclass)    
ip         character varying(50)    
country    character varying(10)    
region     character varying(10)    
city       character varying(50)    
postalCode character varying(10)    
taken      numeric  
date       date

and my query:

INSERT INTO log (ip,country,region,city,postalCode,taken,date) VALUES 
("24.24.24.24","US","NY","Binghamton","11111",1,"2011-11-09")

=> ERROR: column "postalcode" of relation "log" does not exist

second try query : (without postalcode)

INSERT INTO log (ip,country,region,city,taken,date) VALUES 
("24.24.24.24","US","NY","11111",1,"2011-11-09")

=> ERROR: column "24.24.24.24" does not exist

I don't know what I did wrong...

And PostgreSQL does not have datetime type? (2011-11-09 11:00:10)

Solution 1

Try single quotes (e.g. '2011-11-09')

Solution 2

PostgreSQL has a "datetime" type: timestamp. Read the manual here.

The double-qutes "" are used for identifiers if you want them as is. It's best you never have to use them as @wildplasser advised.

String literals are enclosed in single quotes ''.

Start by reading the chapter Lexical Structure. It is very informative. :)

Solution 3

Try it rewrite in this way:

INSERT INTO log (ip,country,region,city,"postalCode",taken,date) VALUES ('24.24.24.24','US','NY','Binghamton','11111',1,'2011-11-09');

When you are using mixed case in the name of column, or reserved words (such as "column", "row" etc.), you have to use double quotes, instead of values, where you have to use a single ones, as you can see in the example.
