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)
