Can I find out the next auto_increment to be used?
Yes, you can find out the next auto_increment with SELECT AUTO_INCREMENT as shown in the below syntax −
SELECT AUTO_INCREMENT FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA= yourDatabaseName AND TABLE_NAME=yourTableName;
Let us first create a table −
mysql> create table DemoTable ( ClientId int NOT NULL AUTO_INCREMENT PRIMARY KEY, ClientName varchar(20), ClientAge int ); Query OK, 0 rows affected (1.33 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable(ClientName,ClientAge) values('John',23); Query OK, 1 row affected (0.35 sec) mysql> insert into DemoTable(ClientName,ClientAge) values('Carol',21); Query OK, 1 row affected (0.28 sec) mysql> insert into DemoTable(ClientName,ClientAge) values('Bob',24); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable(ClientName,ClientAge) values('David',25); Query OK, 1 row affected (0.25 sec)
Following is the query to display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+----------+------------+-----------+ | ClientId | ClientName | ClientAge | +----------+------------+-----------+ | 1 | John | 23 | | 2 | Carol | 21 | | 3 | Bob | 24 | | 4 | David | 25 | +----------+------------+-----------+ 4 rows in set (0.00 sec)
Here is the query to find out the next auto_increment to be used in the above table.
mysql> SELECT AUTO_INCREMENT FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA= 'sample' AND TABLE_NAME='DemoTable';
This will produce the following output −
+----------------+ | AUTO_INCREMENT | +----------------+ | 5 | +----------------+ 1 row in set (0.20 sec)
