Finding Out the Types and Sizes of Returned Columns
Once the select statement has been prepared using the function IldRequest::parse or executed using the function IldRequest::execute, the application can gain access to the column descriptors.
The number of select list columns is given by a call to the member function IldRequest::getColCount. Then, for any index between 0 and that value, the function IldRequest::getColDescriptor returns an instance of the class IldDescriptor.
Table 4.2 shows the IldDescriptor information you can get on the corresponding column.
