Fields
| Name | Value | Description |
|---|---|---|
| NoResults | 0 | The command does not have any results, neither as rows nor as output parameters. |
| NoResultSet | 0 | The command does not have any result set mapping. |
| 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. |
