In a typical MySQL installation, the default character set and collation are latin1 and latin1_swedish_ci. This means that all string comparisons will be performed in a case insensitive manner. So, ‘Search String’=’search string’. This is great for most WHERE expressions, however there are occasions where performing a case-sensitive search is required. Luckily MySQL provides the collate clause which allows you to override whatever the default collation is for a comparison. As an example :
select * from mytable where first_name collate latin1_general_cs=’damon’
This will only return rows will the first_name matches damon exactly. Damon will not match.
You can also use latin1_bin which performs an exact binary match.
If you are unsure of a field or strings collation, you can use the COLLATION(str) function to return the collation of the string argument.
