Metadata about columns in regular and compute rows.
| 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.
| TDS_INT tds_column::column_cur_size | 
size written in variable (ie: char, text, binary).
-1 if NULL.
| TDS_INT tds_column::column_size | 
maximun size of data.
For fixed is the size.
| TDS_SERVER_TYPE tds_column::column_type | 
This type can be different from wire type because conversion (e.g.
type of data, saved from wire
UCS-2->Ascii) can be applied. I'm beginning to wonder about the wisdom of this, however. April 2003 jkl
