I'm sure I'm missing something but looking at the source code for 
tds_submit_query_params (in v0.62.4 query.c) it seems to me that a TDS7 
query with no params will be sent with packet type 0x01 but *not* in 
unicode.

This seems at odds with the documentation for the function.

Am I missing something ?
Does it make any difference ? (I'm certainly not that knowledgeable about 
the use of TDS7).

[I'm looking at the code to better understand how to decode a capture of a 
TDS stream]

Thanks
