Not only should you definitely have one record per day, instead of one record per month, you should think about normalizing your structure further. Try these articles for tips on how to design a database structure:

Hi there, I currently store some information about a users daily habits in a table. The table has 4 fields per day, and another 4 fields as the keys. This table, depending on the month, can be from (4 keys + (28 days * 4 fields per day)) fields, to (4 keys + (31 days * 4 fields per day)) fields long... The table layout is like such: +-----+---+----+-----+------+------+------+------+------+------+------------ -- |name |id |id2 |type |d01f1 |d01f2 |d01f3 |d01f4 |d02f1 |d02f2 |.....and so on +-----+---+----+-----+------+------+------+------+------+------+------------ -- Performance wise, would it be better to have it laid out in a manner such as +-----+---+----+-----+----+---+---+---+---+ |name |id |id2 |type |day |f1 |f2 |f3 |f4 | +-----+---+----+-----+----+---+---+---+---+ So that each row, contains a single days details, rather than have a single row, contain the entire months details? Also, when i would do a select, if i wanted say d02f1, would it load the entire row first, and then just give me that field? -Select `d02f01` from `mytable` where [where clause] Or would it jsut load that field... Does these questions make sense?
