Hi Don;

  Where did you read about a column number of 30 restriction?

Regards ... Chris

Hi Don,

In fact you can create DynamicModels with more than 30 columns. The 30-column restriction mentioned in the API Reference is a recommendation for best performance.  The thing is, we have internally defined the handling of DynamicModel with 1~30 columns.  If there are more columns, the product will internally use one more Dynamic model to handle the additional columns. You need not do special coding, it is just that the performance may be affected.

Note that in the 2019 GA release, you cannot use DynamicModel to generate dynamical datastore yet.  We will add support of dynamically creating datastore in the coming R2 version.  Please see the sample syntax that will be supported in 2019 R2 and let us know if you have further question.

//Sample 1,creating a DynamicModel datastore

string dwtext = ''  ''; //assign the dw syntax to dwtext

var dataobject = DataObject.Create(dwtext);

var ds0 = new DataStore(dataobject, _context);

//Sample 2, dynamically creating a datastore model

string dwtext = ''  ''; //assign the dw syntax to dwtext

var dataobject = DataObject.Create(dwtext);

var ds0 = new DataStore(dataobject, _context);

Best regards, Julie
