    <p>When I make a POST request to my webservice, the following error is generated:</p> <blockquote> <p>TinyTds::Error: Cannot insert the value NULL into column 'BankCD', table 'SlotsMasterData.Master.Bank'; column does not allow nulls.</p> </blockquote> <p>The server console displays the following:</p> <p><img src="https://i.stack.imgur.com/ipyve.png" alt="enter image description here"></p> <p>From the above you can see that values exist for all attributes of my Bank object, but suddenly the reference to each is NULL when 'SELECT CAST(SCOPE IDENTITY() ... ' is performed.</p> <p>This is my app code:</p> <pre><code> RKObjectManager *objectManager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:basePathToWebService]]; RKObjectMapping *bankMapping = [RKObjectMapping mappingForClass:[Banks class]]; NSDictionary *attributeMappingDictionary = [NSDictionary dictionaryWithObjectsAndKeys: @"BankID", @"bankID", @"BankCD", @"bankCD", @"BankName", @"bankName", @"InsertSourceKey", @"insertSourceKey", @"UpdateSourceKey", @"updateSourceKey", @"Active", @"active", nil]; [bankMapping addAttributeMappingsFromDictionary:attributeMappingDictionary]; RKObjectMapping *bankRequestMapping = [RKObjectMapping requestMapping]; [bankRequestMapping addAttributeMappingsFromDictionary:attributeMappingDictionary]; RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:bankMapping method:RKRequestMethodAny pathPattern:@"/banks" keyPath:nil statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)]; RKRequestDescriptor *requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:bankRequestMapping objectClass:[Banks class] rootKeyPath:nil method:RKRequestMethodAny]; [objectManager addResponseDescriptor:responseDescriptor]; [objectManager addRequestDescriptor:requestDescriptor]; [RKMIMETypeSerialization registerClass:[RKNSJSONSerialization class] forMIMEType:@"text/plain"]; //Post [objectManager postObject:bank path:@"/banks" parameters:nil success:nil failure:nil]; </code></pre> <p>Why is an attempt made to insert NULL values? How do I fix this? Thanks for your help!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
