View the auto_increment value for a table in MySQL without using SHOW TABLE?
To view the auto_increment value for a table, you can use INFORMATION_SCHEMA.TABLES.
Let us first create a table −
mysql> create table viewtheauto_incrementValueForATableDemo
-> (
-> StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
-> StudentName varchar(20)
-> );
Query OK, 0 rows affected (0.84 sec)
Following is the query to insert some records in the table using insert command −
mysql> insert into viewtheauto_incrementValueForATableDemo(StudentName)
values('Ramit');
Query OK, 1 row affected (0.23 sec)
mysql> insert into viewtheauto_incrementValueForATableDemo(StudentName) values('Bob');
Query OK, 1 row affected (0.14 sec)
mysql> insert into viewtheauto_incrementValueForATableDemo(StudentName) values('Chris');
Query OK, 1 row affected (0.15 sec)
mysql> insert into viewtheauto_incrementValueForATableDemo(StudentName)
values('Robert');
Query OK, 1 row affected (0.12 sec)
mysql> insert into viewtheauto_incrementValueForATableDemo(StudentName) values('John');
Query OK, 1 row affected (0.46 sec)Following is the query to display all records from the table using a select statement −
mysql> select * from viewtheauto_incrementValueForATableDemo;
This will produce the following output −
+-----------+-------------+
| StudentId | StudentName |
+-----------+-------------+
| 1 | Ramit |
| 2 | Bob |
| 3 | Chris |
| 4 | Robert |
| 5 | John |
+-----------+-------------+
5 rows in set (0.00 sec)
Following is the query to view the auto_increment value for a table −
mysql> SELECT `AUTO_INCREMENT` AS 'NextAutoIncrementValue'
-> FROM `information_schema`.`TABLES`
-> WHERE `TABLE_SCHEMA` = 'test'
-> AND `TABLE_NAME` = 'viewtheauto_incrementValueForATableDemo';
This will produce the following output −
+------------------------+
| NextAutoIncrementValue |
+------------------------+
| 6 |
+------------------------+
1 row in set (0.00 sec)
