How to change the format of select output (SQLite)-CodePudding

On SQLite, I displayed the table "user" as shown below but the select output is not well-formatted so it's difficult to see:

sqlite> .header on
sqlite> select * from user;
id|first_name|last_name|age
1|Steve|Jobs|56
2|Bill|Gates|66
3|Mark|Zuckerberg|38

I want more well-formatted select output something like as shown below or any formats of select output are fine as long as the formats are better than above:

id|first_name|last_name |age
1 |Steve     |Jobs      |56
2 |Bill      |Gates     |66
3 |Mark      |Zuckerberg|38

Are there any ways to change the format of select output?

CodePudding user response：

This command below sets the output mode "box":

.mode box

Then, this is how it looks like below:

sqlite> .header on
sqlite> select * from user;
┌────┬────────────┬────────────┬─────┐
│ id │ first_name │ last_name  │ age │
├────┼────────────┼────────────┼─────┤
│ 1  │ Steve      │ Jobs       │ 56  │
│ 2  │ Bill       │ Gates      │ 66  │
│ 3  │ Mark       │ Zuckerberg │ 38  │
└────┴────────────┴────────────┴─────┘

And, this command below sets the output mode "table":

.mode table

Then, this is how it looks like below:

sqlite> .header on
sqlite> select * from user;
 ---- ------------ ------------ ----- 
| id | first_name | last_name  | age |
 ---- ------------ ------------ ----- 
| 1  | Steve      | Jobs       | 56  |
| 2  | Bill       | Gates      | 66  |
| 3  | Mark       | Zuckerberg | 38  |
 ---- ------------ ------------ -----

There are 14 output modes in total as shown below:

box         Tables using unicode box-drawing characters
csv         Comma-separated values
column      Output in columns.  (See .width)
html        HTML <table> code
insert      SQL insert statements for TABLE
json        Results in a JSON array
line        One value per line
list        Values delimited by "|"
markdown    Markdown table format
qbox        Shorthand for "box --width 60 --quote"
quote       Escape answers as for SQL
table       ASCII-art table
tabs        Tab-separated values
tcl         TCL list elements

And these commands show the details of the command ".mode":

.help .mode

Or:

.help mode

Then, this is how it looks like below:

sqlite> .help .mode
.import FILE TABLE       Import data from FILE into TABLE
   Options:
     --ascii               Use \037 and \036 as column and row separators
     --csv                 Use , and \n as column and row separators
     --skip N              Skip the first N rows of input
     --schema S            Target table to be S.TABLE
     -v                    "Verbose" - increase auxiliary output
   Notes:
     *  If TABLE does not exist, it is created.  The first row of input
        determines the column names.
     *  If neither --csv or --ascii are used, the input mode is derived
        from the ".mode" output mode
     *  If FILE begins with "|" then it is a command that generates the
        input text.
.mode MODE ?OPTIONS?     Set output mode
   MODE is one of:
     ascii       Columns/rows delimited by 0x1F and 0x1E

     csv         Comma-separated values
