So if you really have some data of type Varchar2 in that Column in DB then please try to delete that particular column Content, And try to verify Mapping, hope this will work<div style="clear:both;"></div>https://community.appian.com/thread/39279?ContentTypeID=1Sun, 13 Nov 2016 09:59:26 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:9bff9488-b055-4d93-9a67-ae4a6056850ekondetivotherwise delete the table in database. And publish your data store again.<div style="clear:both;"></div>https://community.appian.com/thread/39278?ContentTypeID=1Sun, 13 Nov 2016 04:49:01 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:71ec548d-53ce-41a9-a0b4-3b5854e386dbaayushaYou need to update the database table by using SQL query, and then try to publish the data store.<div style="clear:both;"></div>
