◆ bcp_column_data

BCPCOLDATA * tds_column::bcp_column_data

◆ bcp_prefix_len

TDS_INT tds_column::bcp_prefix_len

The length, in bytes, of any length prefix this column may have.

For example, strings in some non-C programming languages are made up of a one-byte length prefix, followed by the string data itself. If the data do not have a length prefix, set prefixlen to 0. Currently not very used in code, however do not remove.
