How to find the name of a column in MySQL?
For this, you can use SHOW COLUMNS or INFORMATION_SCHEMA.COLUMN.
Let us first create a table −
mysql> create table DemoTable603 ( ClientId int NOT NULL AUTO_INCREMENT, ClientName varchar(100), ClientAge int, ClientAddress varchar(100), ClientCountryName varchar(100), ClientEducationDetails varchar(200), PRIMARY KEY(ClientId) ); Query OK, 0 rows affected (0.59 sec)
CASE 1 − Using SHOW command
Here is the query to find the name of a column in MySQL −
mysql> SHOW COLUMNS FROM DemoTable603;
This will produce the following output −
+------------------------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +------------------------+--------------+------+-----+---------+----------------+ | ClientId | int(11) | NO | PRI | NULL | auto_increment | | ClientName | varchar(100) | YES | | NULL | | | ClientAge | int(11) | YES | | NULL | | | ClientAddress | varchar(100) | YES | | NULL | | | ClientCountryName | varchar(100) | YES | | NULL | | | ClientEducationDetails | varchar(200) | YES | | NULL | | +------------------------+--------------+------+-----+---------+----------------+ 6 rows in set (0.00 sec)
CASE 2 − Using information_schema.column −
mysql> select column_name from information_schema.columns where table_schema='web' and table_name='DemoTable603';
This will produce the following output −
+------------------------+ | COLUMN_NAME | +------------------------+ | ClientAddress | | ClientAge | | ClientCountryName | | ClientEducationDetails | | ClientId | | ClientName | +------------------------+ 6 rows in set (0.00 sec)
