using none unique index to accelerate update and delete on column-organized

there is a limitation (https://www.ibm.com/support/knowledgecenter/SSEPGG_11.5.0/com.ibm.db2.luw.admin.perf.doc/doc/r0061828.html)

Update and delete operations that use an index scan on a column-organized table are not supported by the FETCH operator. Update and delete operations that affect only a single row are supported by using either index-only access or the nested-loop fetch approach.

delete from whre <conditions> and update <table> set .... where <conditions> use index only it affect a single row.

in migration project (from Oracle, SQLServer,...) to DB2 BLU, there is a huge regression of many job that uses alot of update .... where .... , because the update does not use the index.
