SQLite currently works from the command line (using the “sqlite3” command), Python, Perl, and PHP.
- SSH to your account.
- cd Documents
- mkdir databases
- cd databases
- sqlite3 DATABASENAME
- create table TABLENAME (table information);
- .quit
If you want to be able to change it from the web, add the following steps:
- chmod o+wr DATABASENAME
- chmod g-r DATABASENAME
- chmod o+wx .
- chmod g-rwx .
For example, to create an album database that stores title and artist, you might use:
sqlite3 albumdb create table albums (ID integer primary key, title text, artist text); insert into albums (title, artist) values ("From the Inside", "Alice Cooper"); insert into albums (title, artist) values ("The Wind", "Warren Zevon");
Then, “select * from albums;” will show:
sqlite> select * from albums; 1|From the Inside|Alice Cooper 2|The Wind|Warren Zevon sqlite>
Connecting with Perl
#!/usr/bin/perl $db = "/path/to/albumdb"; use DBI; $dbh = DBI->connect("dbi:SQLite:dbname=$db"); $query = "SELECT title, artist FROM albums"; $sth = $dbh->prepare($query); $sth->execute; while ($ref = $sth->fetchrow_hashref()) { $title = $$ref{'title'}; $artist = $$ref{'artist'}; print "$title ($artist)\n"; }
Connecting with PHP
<? $db = "/path/to/albumdb"; IF ($albums = new PDO("sqlite:$db")): $query = "SELECT title, artist FROM albums"; IF ($albumlist = $albums->query($query)): echo "<table>\n"; FOREACH ($albumlist as $album): $title = $album['title']; $artist = $album['artist']; echo "<tr>"; echo "<td>$title</td>"; echo "<td>$artist</td>"; echo "</tr>\n"; ENDFOREACH; echo "</table>\n"; ELSE: $error = $albums->errorInfo(); echo "<p>Error:", $error[2], "</p>\n"; ENDIF; ELSE: echo "<p>Unable to connect to $db.</p>\n"; ENDIF; ?>
Connecting with Python
#!/usr/bin/python #path to database db = "/path/to/albumdb" import sqlite3 as sqlite sql= sqlite.connect(db) query = "SELECT title, artist FROM albums" cursor = sql.cursor() cursor.execute(query) for row in cursor.fetchall(): title, artist = row print title + " (" + artist + ")"
