  - Microsoft SQL Server Programmer's Toolkit, version 4.2

BUG# 10063 (4.2)

SYMPTOMS

When attempting to specify a string of binary data as a parameter in an remote stored procedure (RPC) execution, you may encounter error 10036:

   Null destination variable not allowed

CAUSE

The function SqlRpcParam will reject attempts to specify a binary parameter if the first byte of the string used as the remote stored procedure parameter is zero.

WORKAROUND

Convert the desired binary value to a character string and execute the stored procedure using SqlCmd%() and SqlExec%().

STATUS

Microsoft has confirmed this to be a problem in DB-Library version 4.20.00. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
