What is the range of int data type in MySQL?

-2147483648 to 2147483647
The signed range of INT is from -2147483648 to 2147483647 and the unsigned range is from 0 to 4294967295. You can specify signed or unsigned int in the column definition. The size parameter specifies the maximum length of the number which is 255.

What is the length of integer data type?

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 data type in MySQL?

A Data Type specifies a particular type of data, like integer, floating points, Boolean, etc. In MySQL, each database table has many columns and contains specific data types for each column. We can determine the data type in MySQL with the following characteristics: The type of values (fixed or variable) it represents.

What is means by INT 11 in MySQL?

In MySQL integer int(11) has size is 4 bytes which equals 32 bit. Signed value is : – 2^(32-1) to 0 to 2^(32-1)-1 = -2147483648 to 0 to 2147483647. Unsigned values is : 0 to 2^32-1 = 0 to 4294967295.

Which is valid int data value?

1.1. A variable of the int data type takes 32 bits of memory. Its valid range is -2,147,483,648 to 2,147,483,647 (-231 to 231– 1).

What is enum data type in MySQL?

The ENUM data type in MySQL is a string object. It allows us to limit the value chosen from a list of permitted values in the column specification at the time of table creation. It is short for enumeration, which means that each column may have one of the specified possible values.

What is data type in database?

A database data type refers to the format of data storage that can hold a distinct type or range of values. When computer programs store data in variables, each variable must be designated a distinct data type. Some common data types are as follows: integers, characters, strings, floating point numbers and arrays.

What does Int 4 mean in MySQL?

For example, INT(4) specifies an INT with a display width of four digits. This optional display width may be used by applications to display integer values having a width less than the width specified for the column by left-padding them with spaces.

What does int(11) mean in MySQL?

A very common misconception about what int(11) means in MySQL is that the column can store maximum integer value with 11 digits in length. However, this is not true. int(11) does not determines the maximum value that the column can store in it.

What is the max length for char type in MySQL?

The CHAR and VARCHAR types are declared with a length that indicates the maximum number of characters you want to store. For example, CHAR (30) can hold up to 30 characters. The length of a CHAR column is fixed to the length that you declare when you create the table. The length can be any value from 0 to 255.

What is the MySQL integer size?

In MySQL integer int(11) has size is 4 bytes which equals 32 bit. Signed value is : – 2^(32-1) to 0 to 2^(32-1)-1 = -2147483648 to 0 to 2147483647 Unsigned values is : 0 to 2^32-1 = 0 to 4294967295

Is there limit to num of columns in MySQL?

MySQL has hard limit of 4096 columns per table, but the effective maximum may be less for a given table. The exact column limit depends on several factors: The maximum row size for a table constrains the number (and possibly size) of columns because the total length of all columns cannot exceed this size.
