Depending on what exactly you want, play around with random() and substring(). bye, -christian- -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Re: rounding digits after decimal sign
Hi, If you want to round your value to the specified no. of digits, use round(). Else if you want to extract the values without rounding use truncate(). mysql select round(blustat,2) from parts; [the value will get rounded to the nearest decimal] or mysql select truncate (blustat,2) from parts; [no rounding, simply extract only the value of specified digits] For More info:http://www.keithjbrown.co.uk/vworks/mysql/mysql_p9.php Thanks, ViSolve DB Team - Original Message - From: Dimitar Vasilev [EMAIL PROTECTED] To: mysql@lists.mysql.com Sent: Thursday, February 01, 2007 1:40 AM Subject: rounding digits after decimal sign Hello, Can anyone point me to a section of manual or link how to reduce digits after a decimal sign?
