we know when type .mode column
let me see tables like column And .headers on
, we can see the header of tables. But I want to know if there is any way make the two default settings?
Do some modify for the source code of sqlite?? OR is there a config file for these settings?
In this mode (which is the default when SQLite is compiled with SQLITE_THREADSAFE=1) the SQLite library will itself serialize access to database connections and prepared statements so that the application is free to use the same database connection or the same prepared statement in different threads at the same time.
SQLite supports page size range from 512 to 65536 bytes.
It is not possible to rename a column, remove a column, or add or remove constraints from a table. The sqlite file format is very simple and that's why this operation is valid.
DB Browser for SQLite allows you to add or drop columns. In the main view, tab Database Structure , click on the table name. A button Modify Table gets enabled, which opens a new window where you can select the column/field and remove it.
Put:
.headers on .mode column
In a file called .sqliterc
in the home directory of the user running sqlite.
(P.S. I found that in man sqlite3
.)
Make sure using the following command to open the file:
nano ~/.sqliterc
then add
.headers on .mode column
to the file and save it
