How to resolve Database naming convention issues ?

prais1852 over 7 years ago

Hi Community,

I am using Microsoft SQL Server for my Application Application. In my CDT (Say Employee) I have an array field (Say Skills) to store checkbox values but the problem is that when i go to data store to verify it and publish. It asks for Employee_Skills table. if i define it as EmployeeSkills then it throws an error saying table not found. Also by default it generates weird column names in the new table. How can i control naming convention of my foreign key table and choose friendly column name ?

I checked everywhere in CDT's XSD file also but i couldn't find any way to change table/column name.

prais1852 , The below snippet would help you. Please modify accordingly in your .xsd file.

<xsd:complexType name="Emplyee">
<xsd:annotation>
<xsd:appinfo source="appian.jpa">
@Table(name="Emplyee_dbtable")
</xsd:appinfo>
</xsd:annotation>
<xsd:sequence>

Hi and Carlos Santander Here is my CDT and XSD. It asks for CCCDetails_NodesAffected and CCCDetails_ToolsAffected tables when i try to publish my CDT to Data Store. How can i overwrote table and column names ? I can't find CCCDetails_NodesAffected and CCCDetails_ToolsAffected table names in my CDT. Please help me to resolve this. I want name to be without underscore i.e. CCCDetailsNodesAffected and CCCDetailsToolsAffected and similarly i want to overwrite the column names as well. I have two fields as Array and i do not want to create Nested CDTs.

Hi Sorry to disturb you again. Can you give your expert advice on this one also if possible. I am finding it difficult to maintain naming convention in MS SQL Server ?

I'm not really an expert at creating DB tables straight from XSD... but by looking at your XSD and the "tables" you're being asked for when you try to publish, its because you haven't pointed NodesAffected or ToolsAffected at any DB table column. You need to use the XSD syntax already pointed out by i'm guessing.

Thanks for the example. But if you can see the screenshot and XSD i have attached. There are two fields ToolsAffected and NodesAffected which are array in my Designer CDT and when i go to publish this CDT Appian automatically asks to create two more table. In XSD i can't see the table/column name which appian suggests. How can i overwrite the name in that case ?

I can see only -

<xsd:element maxOccurs="unbounded" minOccurs="0" name="ToolsAffected" nillable="true" type="xsd:string" /> <xsd:element maxOccurs="unbounded" minOccurs="0" name="NodesAffected" nillable="true" type="xsd:string" />

and Appian is creating other two definition table internally. How can i find them to edit the table and column names ?
