To improve James  excellent answer   It s better to put BINARY in front of the constant instead   SELECT   FROM  table  WHERE  column    BINARY  value    Putting BINARY in front of column will prevent the use of any index on that column

MySQL queries are not case-sensitive by default  Following is a simple query that is looking for  value   However it will return  VALUE    value    VaLuE   etc     SELECT   FROM  table  WHERE  column     value    The good news is that if you need to make a case-sensitive query  it is very easy to do using the BINARY operator  which forces a byte by byte comparison   SELECT   FROM  table  WHERE BINARY  column     value

Whilst the listed answer is correct  may I suggest that if your column is to hold case sensitive strings you read the documentation and alter your table definition accordingly   In my case this amounted to defining my column as    tag  varchar 255  CHARACTER SET utf8 COLLATE utf8 bin NOT NULL DEFAULT      This is in my opinion preferential to adjusting your queries
