Fields

Name	Value	Description
NoResults	0	The command does not have any results, neither as rows nor as output parameters.
HasResultRow	1	The command maps to a row in the result set.
NotLastInResultSet	3	The command maps to a non-last row in the result set.
LastInResultSet	5	The command maps to the last result in the result set.
ResultSetWithRowsAffectedOnly	9	The command maps to a result set which contains only a single rows affected value.
IsPositionalResultMappingEnabled	17	When rows with database-generated values are returned in non-deterministic ordering, it is necessary to project out a synthetic position value, in order to look up the correct ModificationCommand and propagate the values. When this bit is enabled, the current result row contains such a position value.
HasOutputParameters	32	The command has output parameters.
