https://community.appian.com/discussions/f/data/23461/tinyint-replaced-by-bit-in-xsdI couldn&#39;t get my DataStore to to republish a DataType association that&#39;s been around for a year. Finally, I created a new DataType from the same view and compared the downloaded xsd&#39;s Old one: &lt;xsd:appinfo source=&quot;appian.jpa&quot;&gt;@Column(name=&quot;isMultiplePlanen-USTelligent Community 12https://community.appian.com/thread/89884?ContentTypeID=1Wed, 19 Jan 2022 06:21:29 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:786538c6-cc5c-43bf-8a01-dd4eb1295e2eHarshit Bumb (Appyzie)<p>Hi Colin,</p> <p>That might be the case.&nbsp;<br />But&nbsp;BIT is always a better option than&nbsp;TINYINT as the BIT&nbsp;will only store 1 or 0. I have personally only used&nbsp;BIT for any boolean flag on the DB side and then map it to boolean on the Appian side.&nbsp;</p> <p>Thanks,<br />Harshit</p><div style="clear:both;"></div>
