IBCPSession::BCPReadFmt (OLE DB)
Reads format information for each column from the format file.
The BCPReadFmt method is used for reading data from a format file that specifies the format of data in the data file. This method is capable of detecting the correct version of the format file. It can automatically detect whether the format file is in xml or old style text format and behaves accordingly. The format file versions supported by the SQL Server Native Client OLE DB provider BCP are version 6.0 or newer.
After the BCPReadFmt method reads the format values, it makes the appropriate calls to the IBCPSession::BCPColumns and IBCPSession::BCPColFmt methods. There is no need for the user to parse a format file and make these calls.
To save a format file, call the IBCPSession::BCPWriteFmt method. Calls to the BCPReadFmt method can reference saved formats. Alternatively, the bulk-copy utility (bcp) can save user-defined data formats in files that can be referenced by the BCPReadFmt method.
