    <p>I am using</p> <pre><code>$rows = $statement-&gt;fetchAll(PDO::FETCH_ASSOC); </code></pre> <p>to get all the rows of my table.</p> <p>The schema is defined as "id INTEGER PRIMARY KEY, title TEXT, year INTEGER, price REAL"</p> <p>A row from he results of the fetchAll is</p> <pre><code>array(4) { [0]=&gt; string(1) "1" [1]=&gt; string(14) "The Dark Night" [2]=&gt; string(4) "2008" [3]=&gt; string(5) "19.95" } </code></pre> <p>Why are all the data types being returned as strings? I want them to be returned as defined in the schema. I understand the 'typeless' nature of SQLite, but they do define the limited data types as TEXT, INTEGER, and REAL. How can I get the data to be returned with the specified data types? I don't want to iterate through each row, and convert it with PHP - that just seems to be too slow.</p> <p>The Complete Test Code as Follows:</p> <pre><code>&lt;? class sqlite_test { function __construct() { $this-&gt;dbase_filename = "test.sqlite"; $this-&gt;init_dbase(); } function init_dbase() { $this-&gt;pdo = new PDO("sqlite:".$this-&gt;dbase_filename); } function open_table() { $table = "dvds"; if ( ! ($test_to_see_if_table_exists = $this-&gt;pdo-&gt;query("SELECT 1 from $table")) ) { $schema = "id INTEGER PRIMARY KEY, title TEXT, year INTEGER, price REAL"; $query = "CREATE TABLE $table ($schema)"; $this-&gt;pdo-&gt;exec($query); } return $test_to_see_if_table_exists; } function add_test_records() { $query[]='INSERT INTO dvds (id, title, year, price) VALUES (null, "The Dark Night", 2008, 19.95)'; $query[]='INSERT INTO dvds (id, title, year, price) VALUES (null, "The Wizard of Oz", 1939, 9.95)'; $query[]='INSERT INTO dvds (id, title, year, price) VALUES (null, "Jaws", 1977, 6.95)'; $this-&gt;pdo-&gt;exec( join(';', $query) ); } function dump_test_records() { $query = "SELECT * FROM dvds"; if ($statement = $this-&gt;pdo-&gt;prepare($query)) { $statement-&gt;execute(); $rows = $statement-&gt;fetchAll(PDO::FETCH_ASSOC); echo "&lt;pre&gt;"; var_dump($rows); echo "&lt;/pre&gt;"; } } function main() { if ( ! $this-&gt;open_table() ) { $this-&gt;add_test_records(); } $this-&gt;dump_test_records(); } } $test = new sqlite_test(); $test-&gt;main(); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
