Detailed Description
This class functions as a simple wrapper of the PODBCStmt class to fetch/Save data to the Datasource.
Data is fetched on a need to basis and not cached except to create a new row.
Constructor & Destructor Documentation
§ Row()
| PODBC::Row::Row | ( | PODBCStmt * | stmt | ) |
Constructor Create a Dummy row of data to act as a Record Marker.
Template Field are created and Stored in a PARRAY.
Member Function Documentation
§ Column() [1/2]
| Field& PODBC::Row::Column | ( | PINDEX | col | ) |
Retrieve Field Data given the specifed column.
Note: Columns atart at 1 and not exceed PODBCStmt::GetColumnCount()
§ Column() [2/2]
§ ColumnNames()
| PStringArray PODBC::Row::ColumnNames | ( | ) |
Retrieve the Column Names.
§ Columns()
| PINDEX PODBC::Row::Columns | ( | ) |
Columns.
