Fix error in MySQL “select ClientId,ClientName,ClientAge, from tablename”
The error occurs because we have a comma at the end of the column names, just before “from tablename’. Here is the error you may have got −
mysql> select ClientId,ClientName,ClientAge, from DemoTable1391; ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'from DemoTable1391' at line 1
To remove the error, as discussed above, you need to remove the last comma from the table. Let us first create a −
mysql> create table DemoTable1391 -> ( -> ClientId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> ClientName varchar(20), -> ClientAge int -> ); Query OK, 0 rows affected (0.50 sec)
Insert some records in the table using insert −
mysql> insert into DemoTable1391(ClientName,ClientAge) values('Chris',21);
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable1391(ClientName,ClientAge) values('Bob',23);
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable1391(ClientName,ClientAge) values('David',24);
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable1391(ClientName,ClientAge) values('Mike',28);
Query OK, 1 row affected (0.24 sec)Display all records from the table using select −
mysql> select * from DemoTable1391;
This will produce the following output −
+----------+------------+-----------+ | ClientId | ClientName | ClientAge | +----------+------------+-----------+ | 1 | Chris | 21 | | 2 | Bob | 23 | | 3 | David | 24 | | 4 | Mike | 28 | +----------+------------+-----------+ 4 rows in set (0.00 sec)
Following is the query to remove error i.e. this is the correct way of using SELECT statement and fetch records −
mysql> select ClientId,ClientName,ClientAge from DemoTable1391;
This will produce the following output −
+----------+------------+-----------+ | ClientId | ClientName | ClientAge | +----------+------------+-----------+ | 1 | Chris | 21 | | 2 | Bob | 23 | | 3 | David | 24 | | 4 | Mike | 28 | +----------+------------+-----------+ 4 rows in set (0.00 sec)
