Appendix F: ODBC Cursor Library
The cursor library returns values for the following values of InfoType (| represents a bitwise OR); for all other values of InfoType, it calls SQLGetInfo in the driver.
| InfoType | Returned value |
| SQL_BOOKMARK_PERSISTENCE | SQL_BP_SCROLL |
| SQL_DYNAMIC_CURSOR_ATTRIBUTES1 | 0 |
| SQL_DYNAMIC_CURSOR_ATTRIBUTES2 | 0 |
| SQL_FETCH_DIRECTION[1] | SQL_FD_FETCH_ABSOLUTE | SQL_FD_FETCH_FIRST | SQL_FD_FETCH_LAST | SQL_FD_FETCH_NEXT | SQL_FD_FETCH_PRIOR | SQL_FD_FETCH_RELATIVE | SQL_FD_FETCH_BOOKMARK |
| SQL_FORWARD_ONLY_CURSOR_ATTRIBUTES1 | SQL_CA1_NEXT | SQL_CA1_ABSOLUTE | SQL_CA1_RELATIVE | SQL_CA1_LOCK_NO_CHANGE | SQL_CA1_POS_POSITION | SQL_CA1_POSITIONED_DELETE | SQL_CA1_POSITIONED_UPDATE | SQL_CA1_SELECT_FOR_UPDATE |
| SQL_FORWARD_ONLY_CURSOR_ATTRIBUTES2 | SQL_CA2_READ_ONLY_CONCUR | SQL_CA2_OPT_VALUES_CONCURRENCY | SQL_CA2_SENSITIVITY_UPDATES |
| SQL_GETDATA_EXTENSIONS | SQL_GD_BLOCK | any values returned by the driver
Note When data is retrieved with SQLFetchScroll, SQLGetData supports the functionality specified with the SQL_GD_ANY_COLUMN and SQL_GD_BOUND bitmasks. |
| SQL_KEYSET_DRIVEN_CURSOR_ATTRIBUTES1 | 0 |
| SQL_KEYSET_DRIVEN_CURSOR_ATTRIBUTES2 | 0 |
| SQL_LOCK_TYPES[1] | SQL_LCK_NO_CHANGE |
| SQL_STATIC_CURSOR_ATTRIBUTES1 | SQL_CA1_NEXT | SQL_CA1_ABSOLUTE | SQL_CA1_RELATIVE | SQL_CA1_BOOKMARK | SQL_CA1_LOCK_NO_CHANGE | SQL_CA1_POS_POSITION | SQL_CA1_POSITIONED_DELETE | SQL_CA1_POSITIONED_UPDATE | SQL_CA1_SELECT_FOR_UPDATE |
| SQL_STATIC_CURSOR_ATTRIBUTES2 | SQL_CA2_READ_ONLY_CONCUR | SQL_CA2_OPT_VALUES_ CONCURRENCY | SQL_CA2_SENSITIVITY_UPDATES |
| SQL_POS_OPERATIONS[1] | SQL_POS_POSITION |
| SQL_POSITIONED_STATEMENTS[1] | SQL_PS_POSITIONED_DELETE | SQL_PS_POSITIONED_UPDATE | SQL_PS_SELECT_FOR_UPDATE |
| SQL_ROW_UPDATES | "Y" |
| SQL_SCROLL_CONCURRENCY[1] | SQL_SCCO_READ_ONLY | SQL_SCCO_OPT_VALUES |
| SQL_SCROLL_OPTIONS | SQL_SO_FORWARD_ONLY | SQL_SO_STATIC |
| SQL_STATIC_SENSITIVITY[1] | SQL_SS_UPDATES |
[1] Used only when the cursor library is used with an ODBC 2.x driver.
Important The cursor library implements the same cursor behavior when transactions are committed or rolled back as the data source. That is, committing or rolling back a transaction, either by calling SQLEndTran or by using the SQL_ATTR_AUTOCOMMIT connection attribute, can cause the data source to delete the access plans and close the cursors for all statements on a connection. For more information, see the SQL_CURSOR_COMMIT_BEHAVIOR and SQL_CURSOR_ROLLBACK_BEHAVIOR information types in SQLGetInfo.
