How to properly format sqlite shell output?

Question

If I go to mysql shell and type SELECT * FROM users I get -

+--------+----------------+---------------------------------+----------+-----------+--------------------+--------------------+
| USERID | NAME           | EMAILID                         | PASSWORD | USER_TYPE | CONTACT_ID_FKUSERS | COMPANY_ID_FKUSERS |
+--------+----------------+---------------------------------+----------+-----------+--------------------+--------------------+
|    137 | X              | b@cc.com                        | #        | ADMIN     |                166 |                110 |
|    138 | Kshitiz        | ksharma@aaa.com                 | asdf     | ADMIN     |                167 |                111 |
+--------+----------------+---------------------------------+----------+-----------+--------------------+--------------------+

Oracle sqlplus shows -

USERID     NAME  EMAILID    PASSWORD   USER_TYPE  CONTACT_ID_FKUSERS COMPANY_ID_FKUSERS
---------- ----- ---------- ---------- ---------- ------------------ ------------------
137        X     b@cc.com   #          ADMIN                     166                110
137        X     b@cc.com   #          ADMIN                     166                110

Sqlite shell shows -

137|X|b@cc.com|#|ADMIN|166|110
138|Kshitiz|ksharma@aaa.com|asdf|ADMIN|167|111

1. Is there a way to beautify the output from sqlite shell?
2. Is there an alternative shell that's better than default distribution? (CLI clients only)

Answer 1

For "human readable" output, you can use column mode, and turn header output on. That will get you something similar to the sqlplus output in your examples:

sqlite> select * from foo;
234|kshitiz|dba.se

sqlite> .mode column
sqlite> select * from foo;
234         kshitiz     dba.se

sqlite> .headers on
sqlite> select * from foo;
bar         baz         baf
----------  ----------  ----------
234         kshitiz     dba.se

Answer 2

All of the answers provide settings you can type at the SQLite console or via CLI, but nobody mentions that these settings can be put into an RC file to avoid having to type them all the time. Save this as ~/.sqliterc:

.mode column
.headers on
.separator ROW "\n"
.nullvalue NULL

Note I've also added a placeholder for null values, instead of the default empty string.

Answer 3

For those that are interested in getting the same results, except running sqlite from command line. I found that the following doesn't work:

$ sqlite3 <dbfile> ".headers on;.mode column;select * from MyTable"
Error: mode should be one of: ascii column csv html insert line list tabs tcl

Instead, you have to use the options -column and -header with the sqlite command as follows:

$ sqlite3 -column -header <dbfile> "select * from MyTable"

Using:

$ sqlite3 --version 3.8.11.1 2015-07-29 20:00:57 cf538e2783e468bbc25e7cb2a9ee64d3e0e80b2f

Answer 4

I always use

.mode line

which prints query results vertically, similar to MySQL's \G modifier.

Answer 5

As I can't comment yet... In addition to the great answers already provided by Mat and mlissner, if in any case the content of a column is truncated, after giving the right format to the sqlite shell (using .mode column and .headers on as stated above), there is also the possibility to use .explain so the full content of a column is shown.

The only downside to this command is that the columns headers shrink, thus not reading them properly and the output can be quite messy (in a visual scenario), then you can use .explain off to return to the previous format and view it with a more "human readable" format once more.

This approach can be used in conjunction with output formatters commands, and as a temporary solution to view full data of a database/column, as with the use of .width you always have to give the precise number of characters in order to get the full output of a column's data.

For more info on changing output formats, a quick reference to the default CLI documentation:

https://www.sqlite.org/cli.html

Answer 6

Mine looked like a messed with no line breaks. @Boxuan comment on

You might also want to add .separator ROW "\n", so that the rows are separated by line breaks. Mine was not, and the output was unreadable. – Boxuan May 11 at 15:08

Fixed my issue with it as well

Answer 7

You can use .mode tabs for convenience.

sqlite> select * from user;
name    age
Bob     18
Ali     19

Answer 8

On top of everything already said, you can control the width of your columns shown using .width.

Example

.width 8 0 3 9

Then your output will show your first column with a widht of 8 chars, second column auto-adjusting (see below), third column a width of 3 chars, and the fourth will have a width of 9 chars.

Alternative to .width, use an alias name padded with spaces.

Advantage is that you are adjusting the width on the fly in your query only for those columns that require extra width, while the rest of the columns keep using the auto-adjusting width.

All columns will use the auto-adjusting width, that is based on the sqlite documentation width rule:

If you specify a column a width of 0, then the column width is automatically adjusted to be the maximum of three numbers: 10, the width of the header, and the width of the first row of data. This makes the column width self-adjusting. The default width setting for every column is this auto-adjusting 0 value.

Let's say your table "my_table" has the columns "name", "age" and "address". And you are interested in showing:

1. "name": first 20 characters
2. "age": auto-adjusting
3. "address": first 30 characters

Your query will be:

.mode columns
.headers on

CREATE TABLE my_table (name TEXT, age INTEGER, address TEXT);

INSERT INTO my_table VALUES ("short name",
22, "my house");

INSERT INTO my_table VALUES ("my name is very long",
22, "i live in my house somewhere in the planet Earth");

SELECT name AS "name                ",
       age,
       address AS "address                       "
FROM my_table;

Your output:

name                  age         address                       
--------------------  ----------  ------------------------------
short name            22          my house                      
my name is very long  22          i live in my house somewhere i
