SQL Server Native Client (SNAC) is not supported beyond SQL Server 2012. Avoid using SNAC in new development work, and plan to modify applications that currently use it. The Microsoft ODBC Driver for SQL Server provides native connectivity from Windows to Microsoft SQL Server and Microsoft Azure SQL Database.
If the statement attribute SQL_SOPT_SS_PARAM_FOCUS is not 0, SQLExecDirect will return SQL_ERROR and generate a diagnostic record with SQLSTATE=HY024 and the message "Invalid attribute value, SQL_SOPT_SS_PARAM_FOCUS (must be zero at execution time)". For more information about SQL_SOPT_SS_PARAM_FOCUS, see SQLSetStmtAttr.
For more information about table-valued parameters, see Table-Valued Parameters (ODBC).
