Hi,

It is default, whenever we create tables directly from the CDT without editing the CDT xsd. It removes the underscore(_) and always in lower case column names.

If you want the exact same name then after creating the CDT, download the CDT xsd and edit it as Adtiya has suggested :

<xsd:element name="First_Name" nillable="true" type="xsd:string">

<xsd:annotation>

<xsd:appinfo source="appian.jpa">@Column(Name="First_Name",length=10)</xsd:appinfo>

</xsd:annotation>

</xsd:element>

Regards

Abhay

Hi Sudipta,
Download the XSD of that CDT and edit that as below for specific element.

<xsd:element name="first_name" nillable="true" type="xsd:string">
<xsd:annotation>
<xsd:appinfo source="appian.jpa">@Column(name="first_name", length=100)</xsd:appinfo>
</xsd:annotation>
</xsd:element>

Reason why we use XSD upload for CDT creation, we can modify constraints and properties as we need. Thanks

Hi sudiptab,

The names of CDT fields must match the column names in DB.I suggest you to create column names as exactly as CDT names through XSD .Upload the XSD and then verify the data store.And also make sure @ column is properly defined for all the fields .

It is very obvious in the documentation:).If Possible have a glance on it. Here is the link.

Thanks,

Hi sudiptab,

You can download the XSD and map the columns as per your requirement.

Hi sudiptab,

As aditya said, you should change the field name in XSD with respective @Column(length=255, name="example_test")

for better reference follow the below link

are you using xsd to create your cdt?

If not, use a xsd and configure your table column name there. An example would be :

<xsd:element name="first_name" nillable="true" type="xsd:string">
<xsd:annotation>
<xsd:appinfo source="appian.jpa">@Column(length=255, name="first_name")</xsd:appinfo>
</xsd:annotation>
</xsd:element>

The highlighted part indicates the table column name.
