<h2>Recommended Data Types for Qt-Supported Database Systems</h2>
<p>This table shows the recommended data types for extracting data from the databases supported in Qt. Note that types used in Qt are not necessarily valid as input types to a specific database system. e.g., A double might work perfectly as input for floating point records in a particular database, but not necessarily as a storage format for output from that database, because it would be stored with 64-bit precision in C++.</p>

<h3>SQLite Version 2</h3>
<p>SQLite version 2 is "typeless". This means that you can store any kind of data you want in any column of any table, regardless of the declared data type of that column. We recommend that you map the data to <a href="qstring.html">QString</a>.</p>
