SQLRowCount
When arrays of parameter values are bound for statement execution, SQLRowCount returns SQL_ERROR if any row of parameter values generates an error condition in statement execution. No value is returned through the RowCountPtr argument of the function.
The application can take advantage of the SQL_ATTR_PARAMS_PROCESSED_PTR statement attribute to capture the number of parameters processed prior to the error occurring.
Further, the application can use an array of status values, bound by using the SQL_ATTR_PARAM_STATUS_PTR statement attribute, to capture the array offsets of offending parameter rows. The application can traverse the status array to determine the actual number of rows processed.
