How do I view the auto_increment value for a table in MySQL?

In order to view the auto_increment value for a table, you can use SHOW TABLE command.

The syntax is as follows

SHOW TABLE STATUS LIKE 'yourTableName'\G

The syntax is as follows

SELECT `AUTO_INCREMENT`    FROM `information_schema`.`TABLES`    WHERE `TABLE_SCHEMA` = ‘yourDatabaseName’    AND `TABLE_NAME` =’yourTableName';

To understand the above syntaxes, let us create a table. The query to create a table is as follows

mysql> create table viewAutoIncrementDemo    -> (    -> UserId int NOT NULL AUTO_INCREMENT PRIMARY KEY,    -> UserName varchar(20)    -> ); Query OK, 0 rows affected (0.59 sec)

Now you can insert some records in the table using insert command. The query is as follows −

mysql> insert into viewAutoIncrementDemo(UserName) values('John'); Query OK, 1 row affected (0.18 sec) mysql> insert into viewAutoIncrementDemo(UserName) values('Carol'); Query OK, 1 row affected (0.14 sec) mysql> insert into viewAutoIncrementDemo(UserName) values('Bob'); Query OK, 1 row affected (0.08 sec) mysql> insert into viewAutoIncrementDemo(UserName) values('Sam'); Query OK, 1 row affected (0.12 sec) mysql> insert into viewAutoIncrementDemo(UserName) values('Mike'); Query OK, 1 row affected (0.14 sec) mysql> insert into viewAutoIncrementDemo(UserName) values('David'); Query OK, 1 row affected (0.16 sec) mysql> insert into viewAutoIncrementDemo(UserName) values('Larry'); Query OK, 1 row affected (0.11 sec)

Display all records from the table using select statement. The query is as follows −

mysql> select *from viewAutoIncrementDemo;

The following is the output

+--------+----------+ | UserId | UserName | +--------+----------+ |     1 | John      | |     2 | Carol     | |     3 | Bob       | |     4 | Sam       | |     5 | Mike      | |     6 | David     | |     7 | Larry     | +--------+----------+ 7 rows in set (0.00 sec)

Here is the query to view the auto_increment value for a table

mysql> SHOW TABLE STATUS LIKE 'viewAutoIncrementDemo'\G

The following is the output

*************************** 1. row *************************** Name: viewautoincrementdemo Engine: InnoDB Version: 10      Row_format: Dynamic            Rows: 7  Avg_row_length: 2340     Data_length: 16384 Max_data_length: 0    Index_length: 0       Data_free: 0  Auto_increment: 8 Create_time: 2019-03-02 04:05:20 Update_time: 2019-03-02 04:06:11 Check_time: NULL Collation: utf8_general_ci Checksum: NULL Create_options: Comment: 1 row in set (0.08 sec)

The following is the second query

mysql> SELECT `AUTO_INCREMENT` -> FROM `information_schema`.`TABLES` -> WHERE `TABLE_SCHEMA` = 'sample' -> AND `TABLE_NAME` = 'viewAutoIncrementDemo';

The following is the output

+----------------+ | AUTO_INCREMENT | +----------------+ | 8 | +----------------+ 1 row in set (0.00 sec)
