I have many tables that use float (in production database), if I convert all of the float column to DOUBLE or DECIMAL (using alter ), is there any impact or anything I should know that could happen to me ?
You'll get a slight slow-down in performance - a trade-off you will make if you choose DECIMAL instead of FLOAT. Even if you choose DOUBLE, there is a risk of rounding errors. Try converting/casting the integer '1234567890' to float/double and assign the resulting float to an integer variable - then see what difference it makes. With DECIMAL you get accurate monetary calculations but slightly slower speed. -- Asif -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
