Subject: RE: create own auto increment number
Are you talking about a multiple key PRIMARY KEY?
CREATE TABLE Blah
(
MyDate datetime,
MyID INT NOT NULL AUTO_INCREMENT,
...
PRIMARY KEY (MyDate,MyID)
)
for each unique MyDate the Auto Increment sequence will start
as:
SELECT CONCAT(id_field,'-',date_field) AS ID,
.

Every time you insert a record, you set the date field and the other field will
auto_increment
