ODBC bookmarks

A bookmark is a value that identifies a row of data.

HCL OneDB™ ODBC Driver supports bookmarks with SQLFetchScroll and SQLExtendedFetch and does not support them with SQLBulkOperations.HCL OneDB ODBC Driver supports bookmarks to the following extent:

Uses only variable length bookmarks.
SQL_DESC_OCTET_LENGTH is set to 4 for bookmark columns.
A bookmark is an integer that contains the row number within the row set, starting with 1.
Bookmarks persist only if the cursor remains open.
SQLFetchScroll, using SQL_FETCH_BOOKMARK for the fetch orientation argument, is fully supported.
SQLBulkOperations does not update the bookmark column for SQL_ADD.

For more information about ODBC bookmarks, see the HCL OneDB ODBC Driver Programmer's Manual.
