In MySQL, the DECIMAL and NUMERIC data types store exact, fixed-point values. In MySQL, NUMERIC is implemented as a DECIMAL, so a NUMERIC and DECIMAL are the same data type. This data type is used when it is important to preserve the exact precision, such as storing money data. Declaration In a DECIMAL column declaration, the precision and scale can be specified. DECIMAL(13,2)This declaration declares a precision of 13 and a scale of 2.

The Short Answer (TL;DR)

If GAAP Compliance is required or you need 4 decimal places:

DECIMAL(13, 4)

Which supports a max value of:

$999,999,999.9999

Otherwise, if 2 decimal places is enough:

DECIMAL(13,2)

Which supports a max value of:

$99,999,999,999.99

Reset MySQL Root Password with One Command

I have locked myself out of important accounts more than a few times. Just this morning, I found myself again locked out of a MySQL database server on an Ubuntu Linux machine. Though this should work with any Debian-based Linux that uses the apt-get package management system.

Fortunately, I had administrative access to the server through SSH and thus was able to reset the MySQL root password with the package management script. It only took one, simple command.
