https://community.appian.com/discussions/f/general/19062/longtext-datatype-in-xsdI am creating CDT for one table stored in cloud database but one column with datatype &#39;longtext&#39; is not fetched in the CDT. So I have tried to add this column explicitly in the downloaded XSD file of this CDT by using the below code: &lt;xsd:element nameen-USTelligent Community 12https://community.appian.com/thread/75084?ContentTypeID=1Tue, 30 Jun 2020 17:14:13 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:e319272e-54f0-4f95-b8fd-f27b024df26dayushimittal<p>Thank you for your response.</p> <p>The issue has been resolved now. I was facing the issue because of the character limit of excel sheet. The data stored in the appian database table having &#39;longtext&#39; datatype is having data with more than 32,767&nbsp;characters which is more than excel character limit i.e. 32,767.</p> <p>After truncating the data from the column in the appian database, the error got resolved and I am able to export data in the excel sheet successfully.</p> <p></p><div style="clear:both;"></div>https://community.appian.com/thread/74992?ContentTypeID=1Fri, 26 Jun 2020 02:01:55 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:ce71eb71-3d5c-4bcf-98c9-03f8a7264d0aCarlos Santander<p>The type <code>longtext</code> might not be supported (see&nbsp;<a href="https://docs.appian.com/suite/help/20.2/Generating_Database_Tables_from_CDTs.html#default-column-types-based-on-xsd-types">https://docs.appian.com/suite/help/20.2/Generating_Database_Tables_from_CDTs.html#default-column-types-based-on-xsd-types</a>).
