I have posted a similar question on the blojsom group but I feel I will
have better chance of an answer here.
Blojsom 3 was developed using MySQL5 for it's back end. However the
host I am with uses 4.0.25 and are unwilling to upgrade - which is fair
enough.
So I decided to see what I can do to make the database creation scripts
MySQL4 compliant. The CHARSET was the easy one - just change it to
CHARACTER SET but the next one was more tricky:
The problem I am having is that version 4 fails giving a syntax error
for the single quotation marks. It appears the script (which was written
on a Mac using MySQL dump 10.9 if that is any help) uses ` and not ',
but doing a general search and replace doesn't fix it. I've searched
the online docs regarding quotes but came up short (too many hits with
too many unrelated items) so if anyone knows the exact url that would be
helpful too.
Here's a snippet of the code:
DROP TABLE IF EXISTS `Blog`;
CREATE TABLE `Blog` (
`blog_id` varchar(50) NOT NULL,
PRIMARY KEY (`blog_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
Thanks, G.
Single quotes (') are for strings. Backticks (`) are for identifiers. To the
best of my knowledge, this hasn't changed from 4.0 to 5. Hence, using your
table definition,
INSERT INTO `Blog` (`blog_id`) VALUES ('This is a blog id');
would be correctly quoted.
Strictly speaking, you only need to quote identifiers which wouldn't otherwise
be allowed (reserved words), so none of the backticks are needed in your example
(or in mine). See the manual for details:
<http://dev.mysql.com/doc/refman/4.1/en/legal-names.html>
<http://dev.mysql.com/doc/refman/4.1/en/reserved-words.html>
What leads you to believe your error is related to quoting? I think it is more
likely to be something else. If you post the query that gives the error and
include the exact error message, I'm sure someone will be able to identify the
problem.
