Upon inserting the value 9223372036854775806 into the subject_id column, the sequence automatically adjusts to set 9223372036854775807 as the next value. Let us check the records of the subjects table by using the same select query that gives the following output – select * from subjects Let us insert one record mentioning the subject_id column value as follows – INSERT INTO We can see that the subject_id column has got the default autoincremented values as 1,2, and 3. Let us check the inserted records by firing the command – select * from subjects Let us insert some values in the table subjects using the following query – INSERT INTO
#MYSQL CREATE TABLE INTEGER COLUMN PLUS#
The sequence value is then set as that inserted value plus 1 for subsequent inserts. However, if a non-null and non-zero value is provided, it is accepted and used as the inserted value. Subject_id BIGINT AUTO_INCREMENT PRIMARY KEY,įor an auto_increment column, if a null or zero value is inserted, the sequence automatically increments the value by 1 from the last maximum value. For this, firstly, We will have to use the educba database, for which we will execute the following query –įurther, we will create the table named subjects that will contain subject_id as the primary key column of BIGINT datatype and one more unsigned BIGINT column named pages wing the following query – CREATE TABLE subjects ( For example, we will create a table named subjects inside the educba database on my server. Let us create a table containing the column as the BIGINT data type that will be the primary key and one more column that will be of BIGINT datatype but not a primary key. That means in case if your table is going to contain only too many records and you want to declare an integral column that will store the autoincremented whole numbers, then instead of using the MySQL INT or INTEGER data type, you will declare the datatype of the column as BIGINT. With BIGINT, you can ensure that the stored values in this column will not exceed the data type’s range. This is especially valuable when the table is expected to contain a substantial number of records, surpassing the range of INT (4294967295). Another scenario for using BIGINT is declaring the primary key of a table to store auto-incremented values. We commonly use the BIGINT data type to store large integral values. The range of the signed BIGINT datatype from minimum to maximum value is -9223372036854775808 to 9223372036854775807, which includes almost 20 characters! While for unsigned BIGINT datatype, it is 0 to 18446744073709551615.
It takes 8 bytes to store the value of the BIGINT data type.
By default, it is signed BIGINT in its functionality. By default, integral data types in MySQL are considered signed. Signed data types enable storage of both positive and negative integral values, while unsigned data types exclusively store positive integer values. MySQL allows the declaration of each integral data type as either signed or unsigned.
