are string matches in MySql normally case insenstive?

If I make this query with MySql:

SELECT * WHERE keyword='urbani sm'

is the comparison case insensitive? Will MySql return all rows where
keyword equals both 'urbanism' and 'Urbanism'?

I searched this using Google Groups, and was suprised that there were
no entries on this. This seems almost FAQ material.

A better place than google groups is in the mysql manual.

The section called "Comparison Operators" says that "...By default, string
comparisons are not case sensitive...". A quick test at the mysql> prompt
shows that that is indeed the case.

I have not checked how one turns off the default to make the comparison
case sensitive.

Text columns are case insensitive. If you want case sensitivity, you
need to make the column BINARY. It's in the manual - if you know what
you're looking for.

I am trying to take a string and split it into a filename and a number where the number is what follows the *last* instance of a comma in that string. Split and explode won't work because if the filename part of the original string contains a , then I end up with too many parts. if (!preg_match ('/^(.*),(+)$/', $string, $matches)) {throwError ();} also fails, because the first part of the regular expression becomes greedy if there is...

I have some php scripts that I use on several machines. Each machine has an identical copy of a mysql database that the scripts run against.

However, I don't know how to test the variable that contains...

Hi all, Using C# 1.1: I need a fast way of determining whether a string is in a list of approx 150 keyword like strings. in two versions: one case-sensitive, the other one case-insenstive. I thought of loading the keywords in a Hastable as Keys with null values, and then use Hastable.ContainsKey(string) but Hashtable does not seem to support case-insentive keys.

Hi there I've noticed some very weird things happening with my current MySQL setup on my XP Laptop, a development machine. For a while, I have been trying to get the MySQL cache to work. Despite entering the required lines to "my.ini" (the new my.cnf) through notepad AND MySQL Administrator, the cache does not work. So, today I took a peek at the 'Health' tab in MySQL Administrator.
