[sqlite] binding paramters for SELECT

[Dixon]

I have prepared the following wide text string:
   L"SELECT ROWID FROM indext WHERE state='1' AND clientName='?' ORDER
   BY size DESC"

with sqlite3_prepare16,  I then call sqlite3_bind_parameter_count on the 
resulting statement.  I get 0 back when I expected 1.  Is this an 
invalid way to specify a placeholder for a variable that I will bind later?
