mode

mode [COLUMN | LINE | JSON [-pretty] | CSV] 

Sets the output mode of query results. The default value is JSON.

For example, a table shown in COLUMN mode:

sql-> mode column;
sql-> SELECT * from users;
 +-----+-----------+-----------+-----+
 | id  | firstname | lastname  | age |
 +-----+-----------+-----------+-----+
 |   8 | Len       | Aguirre   |  42 |
 |  10 | Montana   | Maldonado |  40 |
 |  24 | Chandler  | Oneal     |  25 |

Empty strings are displayed as an empty cell.

sql-> mode column;
sql-> SELECT * from tab1 where id = 1;
 +----+------+----+------+
 | id |  s1  | s2 |  s3  |
 +----+------+----+------+
 |  1 | NULL |    | NULL |

1 row returned

For nested tables, identation is used to indicate the nesting under column mode:

sql-> SELECT * from nested;
+----+-------+------------------------------------------------------------+
| id | name  |                           details                          |

For example, a table shown in LINE mode, where the result is displayed vertically and one value is shown per line:

sql-> mode line;
sql-> SELECT * from users;

 > Row 1
 +-----------+-----------+
 | id        | 8         |
 | firstname | Len       |
 | lastname  | Aguirre   |
 | age       | 42        |
 +-----------+-----------+

  > Row 2
 +-----------+-----------+
 | id        | 10        |
 | firstname | Montana   |
 | lastname  | Maldonado |
 | age       | 40        |
 +-----------+-----------+

  > Row 3
 +-----------+-----------+
 | id        | 24        |
 | firstname | Chandler  |
 | lastname  | Oneal     |
 | age       | 25        |
 +-----------+-----------+
 ...
100 rows returned 

Just as in COLUMN mode, empty strings are displayed as an empty cell:

sql-> mode line;
sql-> SELECT * from tab1 where id = 1;

 > Row 1
 +---------+------+
 | id      | 1    |
 | s1      | NULL |
 | s2      |      |
 | s3      | NULL |
 +---------+------+

1 row returned

For example, a table shown in JSON mode:

sql-> mode json;
sql-> SELECT * from users;
{"id":8,"firstname":"Len","lastname":"Aguirre","age":42}
{"id":10,"firstname":"Montana","lastname":"Maldonado","age":40}
{"id":24,"firstname":"Chandler","lastname":"Oneal","age":25}

{"id":14,"firstname":"Thomas","lastname":"Wallace","age":48}
{"id":41,"firstname":"Vivien","lastname":"Hahn","age":47}
...
100 rows returned 

Empty strings are displayed as "".

sql-> mode json;
sql-> SELECT * from tab1 where id = 1;
{"id":1,"s1":null,"s2":"","s3":"NULL"}

1 row returned

Finally, a table shown in CSV mode:

sql-> mode csv;
sql-> SELECT * from users;
8,Len,Aguirre,42
10,Montana,Maldonado,40
24,Chandler,Oneal,25
30,Pascale,Mcdonald,35
34,Xanthus,Jensen,55
35,Ursula,Dudley,32
39,Alan,Chang,40
6,Lionel,Church,30
25,Alyssa,Guerrero,43
33,Gannon,Bray,24
48,Ramona,Bass,43
76,Maxwell,Mcleod,26
82,Regina,Tillman,58
96,Iola,Herring,31
100,Keane,Sherman,23
3,Bruno,Nunez,49
14,Thomas,Wallace,48
41,Vivien,Hahn,47
...
100 rows returned 

Like in JSON mode, empty strings are displayed as "".

sql-> mode csv;
sql-> SELECT * from tab1 where id = 1;
1,NULL,"","NULL"

1 row returned 

Note:

Only rows that contain simple type values can be displayed in CSV format. Nested values are not supported.
