How to get max(id) of row data in MySQL?

To get max(id), use MAX() method in MySQL. Following is the syntax −

select MAX(yourColumnName) AS anyAliasName from yourTableName;

Let us first create a table −

mysql> create table DemoTable710 (Id int);
Query OK, 0 rows affected (0.53 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable710 values(1001);
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable710 values(2001);
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable710 values(1998);
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable710 values(1789);
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable710 values(1678);
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable710 values(9087);
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable710 values(1908);
Query OK, 1 row affected (0.17 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable710;

This will produce the following output -

+------+
| Id   |
+------+
| 1001 |
| 2001 |
| 1998 |
| 1789 |
| 1678 |
| 9087 |
| 1908 |
+------+
7 rows in set (0.00 sec)

Following is the query to get max(id) of row data in MySQL −

mysql> select MAX(Id) AS Max_Id from DemoTable710;

This will produce the following output -

+--------+
| Max_Id |
+--------+
| 9087   |
+--------+
1 row in set (0.00 sec)
