I want to store many records in a MySQL database. All of them contains money values. But I don't know how many digits will be inserted for each one.
Which data type do I have to use for this purpose?
VARCHAR or INT (or other numeric data types)?
966
Unlike the DECIMAL data type, the MONEY data type is always treated as a fixed-point decimal number. The database server defines the data type MONEY(p) as DECIMAL(p,2). If the precision and scale are not specified, the database server defines a MONEY column as DECIMAL(16,2).
Standard SQL requires that DECIMAL(5,2) be able to store any value with five digits and two decimals, so values that can be stored in the salary column range from -999.99 to 999.99 . In standard SQL, the syntax DECIMAL( M ) is equivalent to DECIMAL( M ,0) .
The first important rule is, always store values as fractional units. It can be tempting to store a value such as $10 as 10.00 in your database. However, storing monetary values with a decimal point can cause a lot of issues. Instead, you should always store monetary values in their minor unit form.
Since money needs an exact representation don't use data types that are only approximate like float. You can use a fixed-point numeric data type for that like
decimal(15,2) 15 is the precision (total length of value including decimal places)2 is the number of digits after decimal pointSee MySQL Numeric Types:
These types are used when it is important to preserve exact precision, for example with monetary data.

You can use DECIMAL or NUMERIC both are same
The DECIMAL and NUMERIC types store exact numeric data values. These types are used when it is important to preserve exact precision, for example with monetary data. In MySQL, NUMERIC is implemented as DECIMAL, so the following remarks about DECIMAL apply equally to NUMERIC. : MySQL
i.e. DECIMAL(10,2)
