Error verifying datastore


I made changes to the View (added a column to the view with datatype = text). Added the same definition to the CDT by adding new column with datatype=text.

When i try to verify the datastore, it is giving me the below error

The data source schema does not match the type mappings: Wrong column type in Appian.p_my_view for column fs_structure. Found: text, expected: VARCHAR(341) (APNX-2-4056-000). see below for CDT definition and view definition. There are other column exists in the view with text and it doesnt complain.

any help is appreciated.

  • Hi there,

    Could you check the XSD for the View CDT and see if you have something similar to the code below:

    <xsd:element name="financialStructure" nillable="true" type="xsd:string">
    	  <xsd:appinfo source="YOURSOURCE">@Column(name="fs_structure", nullable=true, columnDefinition="VARCHAR(341)")</xsd:appinfo>

    I'm not sure if you already tried that, but maybe you just need to download and edit the XSD and create a new version of the CDT.


    Acacio B.

  • hi Thank you so much for your help. I already tried creating new version from XSD. It still complains

    I also tried the solution suggested below and it still complains the same.

    Our DB was migrated from MySQL to MariaDB. Not sure if this is the root causee.

    Thank you so much for your time and  attention! You are awesome!. Have  a great day
