Hi.  I'm looking for a way in my web api to obtain the column data types from a sql select statement. I am currently trying to use  datastore.Describe( colName.ColType ) which returns "System.String" and "System.Decimal" without the length of the string and precision of the decimal. Is there some other datastore property I can use with the Describe method in order to obtain these values?

using PowerScript.Bridge;

   var dwMeta = DwMeta.CreateFromSql(sqlSelect, _dataContext);
   IDataStore ds = DataStore.Create(dwMeta, _dataContext);

   int columnCount = int.Parse(ds.Describe("Datawindow.Column.Count"));
   for (int colNo = 1; colNo <= columnCount ; colNo++)
   {
      string colName = ds.Describe("#" + (colNo - 1) + ".Name");
      string colType = ds.Describe(colName + ".ColType");
   }

Thanks.

 

Possibile BUG in Dataconvertion with Snapdevelop How to initialize DataWindow in C# by its attribute?
