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)
