I am reading in a big file (60MB) 5k at a time, which I find is a lot faster than byte-by-byte. The problem is, if the file does not divide exactly by 5k (which it clearly very rarely will), then I miss out on the last bytes of the file, i.e. when my program tries to pick up 5k but cannot get...

I altered the user table in the mysql database to have % as host, but it makes no diff. I note that I *can* access...

Is it possible to make a two UNIQUE keys in a MySQL table which work together? i.e. I have two fields in a table, either one can be the non-unique in different records, but not at the same time. so in programming terms, it's like saying if (Value1 is unique AND Value2 is unique) { CANNOT MAKE...

Is there a way to find out what the PRIMARY KEY is in a table? i.e. can I say 'SELECT PRIMARY KEY FROM mytable' and get the name of the column which is the primary key? Thanks a lot.

I am setting up a web server which will allow username/password restricted access, is there an easy way to tell Apache to use a different cgi-bin folder depending on the user which logs on? i.e john - /Users/john bill - /Users/william
