Set options while creating a MySQL table. Display the same options as well
To display, use DESC command or information_schema.columns. Let us first create a table and set options −
mysql> create table DemoTable ( Color SET('RED','GREEN','BLUE','YELLOW') ); Query OK, 0 rows affected (0.47 sec)
Case 1
Here is the query to get the list of available options for SET using the DESC command −
mysql> desc DemoTable;
This will produce the following output −
+-------+------------------------------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------+------------------------------------+------+-----+---------+-------+ | Color | set('RED','GREEN','BLUE','YELLOW') | YES | | NULL | | +-------+------------------------------------+------+-----+---------+-------+ 1 row in set (0.00 sec)
Case 2
Here is the query for a list of available options for SET using the information_schema.columns concept −
mysql> select column_type from information_schema.columns where table_name = 'DemoTable' and column_name = 'Color';
This will produce the following output −
+------------------------------------+ | COLUMN_TYPE | +------------------------------------+ | set('RED','GREEN','BLUE','YELLOW') | +------------------------------------+ 1 row in set (0.01 sec)
