Hello,
Thank you for your answer!
But this is the same what I do exactly.
I have realized the stored procedure call with a varchar parameter value
which originally contained characters with the ASC-codes from 1 to 255.
For visualization purpose all these chars were separated by char '-'.
A log file was produced by the ODBC driver is attached.
Look at the "GetPartitionName_sp" stored procedure call.
I suppose that the first parameter was converted to UTF-8.
But I didn't do this conversion!

Hello,
Try to use statements with parameters:
SQLBindParameters(stmt, 1, SQL_PARAM_INPUT, SQL_C_CHAR, SQL_VARCHAR,
query_length, 0, param_ptr, query_length, buff_ptr);
SQLExecDirect(stmt, "{call SomeProc(?}}");
