Description:
The code snippet below (the last function in a larger list) fails.

// set the statement parameters for row-wise binding
sql_retcode = SQLSetStmtAttr(sql_statement_handle, 
                             SQL_ATTR_ROW_BIND_TYPE, 
                             (SQLPOINTER)result_row_struct_size, 
                             0);

When the function returns, sql_retcode is set to SQL_ERROR. No additional information is available from SQLGetDiagRec. This snippet works with ODBC connector v3.51.12.0. The ODBC trace follows:

How to repeat:
Call SQLSetStmtAttr with a statement handle and SQL_ATTR_ROW_BIND_TYPE.

Suggested fix:
SQLSetStmtAttr should accept the SQL_ATTR_ROW_BIND_TYPE attribute and set the row binding type accordingly. Or, if this function is not supported, useful error information should be returned by SQLGetDiagRec.

Andrew, thanks for the bug report. We don't currently support this feature, but I'll fix the diagnostic issue.

Hi Andrew and thanks for your report.

SQL_ATTR_ROW_BIND_TYPE should work fine in Connector/ODBC 3.51 and 5.1. No further development is happening on 5.0.
