Search an SQL database using sqlite3
https://www.sqlite.org/index.html
sqlite
implements a small, fast, self-contained, high-reliability, full-featured, SQL database engine to query .sql
files.
Getting started
To use sqlite, you must have a valid metadata file with a .db
file extension, and an installed version of SQL. This tutorial assumes knowledge of the command line.
To start the sql engine, type:
sqlite3
The prompt will change, showing that the sqlite engine has been initialised. To open a metadata file, type:
.open filename.db
You can then display tables with:
.tables
Based on what is returned, you can then query the content of each table with commands such as:
SELECT * FROM tablename
You may want to have a more human-readable view of the data that is printed in the terminal, by organising the headings and columns:
.headers ON
.mode column
You will get output like:
.headers on
.mode column
select * from mytable;
id foo bar
---------- ---------- ----------
1 val1 val2
2 val3 val4
You can also display detailed views of the contents of tables, with
