How to select all rows from a table except the last one in MySQL?

You need to use != operator along with subquery. The syntax is as follows −

select *from yourTableName where yourIdColumnName != (select max(yourIdColumnName)
from yourTableName );

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

mysql> create table AllRecordsExceptLastOne
   -> (
   -> Id int NOT NULL AUTO_INCREMENT,
   -> UserName varchar(10),
   -> UserAge int 
   -> ,
   -> PRIMARY KEY(Id)
   -> );
Query OK, 0 rows affected (0.65 sec)

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

mysql> insert into AllRecordsExceptLastOne(UserName,UserAge) values('John',21);
Query OK, 1 row affected (0.12 sec)
mysql> insert into AllRecordsExceptLastOne(UserName,UserAge) values('Carol',28);
Query OK, 1 row affected (0.18 sec)
mysql> insert into AllRecordsExceptLastOne(UserName,UserAge) values('Mike',22);
Query OK, 1 row affected (0.13 sec)
mysql> insert into AllRecordsExceptLastOne(UserName,UserAge) values('Sam',29);
Query OK, 1 row affected (0.14 sec)
mysql> insert into AllRecordsExceptLastOne(UserName,UserAge) values('David',27);
Query OK, 1 row affected (0.11 sec)
mysql> insert into AllRecordsExceptLastOne(UserName,UserAge) values('Larry',24);
Query OK, 1 row affected (0.20 sec)

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

mysql> select *from AllRecordsExceptLastOne;

The following is the output −

+----+----------+---------+
| Id | UserName | UserAge |
+----+----------+---------+
|  1 | John     |      21 |
|  2 | Carol    |      28 |
|  3 | Mike     |      22 |
|  4 | Sam      |      29 |
|  5 | David    |      27 |
|  6 | Larry    |      24 |
+----+----------+---------+
6 rows in set (0.00 sec)

Here is the query to select all rows from a table except the last one −

mysql> select *from AllRecordsExceptLastOne where Id!=(select max(Id) from
AllRecordsExceptLastOne);

The following is the output −

+----+----------+---------+
| Id | UserName | UserAge |
+----+----------+---------+
|  1 | John     |      21 |
|  2 | Carol    |      28 |
|  3 | Mike     |      22 |
|  4 | Sam      |      29 |
|  5 | David    |      27 |
+----+----------+---------+
5 rows in set (0.04 sec)
