What is a Tinyint in MySQL?
TINYINT − A very small integer that can be signed or unsigned. If signed, the allowable range is from -128 to 127. If unsigned, the allowable range is from 0 to 255. You can specify a width of up to 4 digits.
What is medium int?
A medium-sized integer. The signed range is -8388608 to 8388607. The unsigned range is 0 to 16777215. ZEROFILL pads the integer with zeroes and assumes UNSIGNED (even if UNSIGNED is not specified). INT3 is a synonym for MEDIUMINT .
What is integer in MySQL?
In MySQL, INT stands for the integer that is a whole number. An integer can be written without a fractional component e.g., 1, 100, 4, -10, and it cannot be 1.2, 5/3, etc. An integer can be zero, positive, and negative. MySQL supports all standard SQL integer types INTEGER or INT and SMALLINT .
When should I use Bigint in MySQL?
The number is used to display width. BIGINT takes 8 bytes i.e. 64 bits. The signed range is -9223372036854775808 to 9223372036854775807 and unsigned range takes positive value.
What is the range of int?
The INTEGER data type stores whole numbers that range from -2,147,483,647 to 2,147,483,647 for 9 or 10 digits of precision. The number 2,147,483,648 is a reserved value and cannot be used.
What is the highest value of Tinyint?
