Queries > Finding Out the Types and Sizes of Returned Columns 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.
