The following table illustrates all date and time data types that support in MySQL: Data Type Syntax When we insert the invalid value, MySQL cannot represent it, and then zero value is used. Each temporal type contains values, including zero. This data type is used to represent temporal values such as date, time, datetime, timestamp, and year. It considered numeric value 1 as true and 0 as false. It is used only for the true and false condition. Here, M determines the number of bit per value that has a range of 1 to 64.
It is used for storing bit values into the table column. Defining the display length (m) and the number of decimals (d) is required. In unpacked decimals, each decimal corresponds to one byte. It requires 8 bytes for storage.Īn unpacked floating-point number that cannot be unsigned. Decimal precision can go to 53 places for a double. This is not required and will default to 16,4, where 4 is the number of decimals. You can define the display length (m) and the number of decimals (d). It is a double-precision floating-point number that cannot be unsigned. Decimal precision can go to 24 places for a float type. This is not required and will default to 10,2, where 2 is the number of decimals, and 10 is the total number of digits (including decimals). It is a floating-point number that cannot be unsigned. We can specify a width of up to 20 digits. It is a large integer that can be signed or unsigned. We can specify a width of up to 11 digits. If unsigned, the allowable range is from 0 to 4294967295. It is a normal-sized integer that can be signed or unsigned. We can specify a width of up to 9 digits.
If unsigned, the allowable range is from 0 to 16777215. If signed, the allowable range is from -8388608 to 8388607. It is a medium-sized integer that can be signed or unsigned. We can specify a width of up to 5 digits. If unsigned, the allowable range is from 0 to 65535. If signed, the allowable range is from -32768 to 32767. It is a small integer that can be signed or unsigned. We can specify a width of up to 4 digits. If unsigned, the allowable range is from 0 to 255. If signed, the allowable range is from -128 to 127. It is a very small integer that can be signed or unsigned. The following table contains all numeric data types that support in MySQL: Data Type Syntax In MySQL, numeric data types are categories into two types, either signed or unsigned except for bit data type. It also supports BIT datatype to store bit values. These data types can include the exact numeric data types (For example, integer, decimal, numeric, etc.), as well as the approximate numeric data types (For example, float, real, and double precision). MySQL has all essential SQL numeric data types. It uses many different data types that can be broken into the following categories: numeric, date and time, string types, spatial types, and JSON data types. MySQL supports a lot number of SQL standard data types in various categories. How MySQL performs a comparison of values of a particular data type.The storage space it takes is based on whether the values are a fixed-length or variable length.The type of values (fixed or variable) it represents.We can determine the data type in MySQL with the following characteristics: In MySQL, each database table has many columns and contains specific data types for each column. It also identifies the possible values for that type, the operations that can be performed on that type, and the way the values of that type are stored. A Data Type specifies a particular type of data, like integer, floating points, Boolean, etc.
