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:

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%().
