    Update a table with matching null values


      I need to update a table that is having null values in its two columns and need to update theses null values with not null values from other table


      The matching records that subject to be updated is driven from a select statement from another table


      Two tables

      1, arf_site_visit

      2  arf_line_item


      Need to update  two columns (site_visit_id,session_id) of table arf_line_item based on the below given join query


      SELECT v.site_visit_id,



            arf_site_visit v,

            arf_line_item i


            i.submit_day_id >= v.start_day_id

            AND i.submit_day_id <= v.end_day_id

            AND i.submit_time_id >= v.start_time_id

            AND i.submit_time_id <= v.end_time_id

            AND i.session_id IS NULL

          You can try something like  make sure your  select Query return the row what you want to update

          update arf_line_item i

          set (i.site_visit_id,i.session_id)=(SELECT v.site_visit_id,v.session_id  FROM  arf_site_visit v

               where  i.submit_day_id >= v.start_day_id

               AND i.submit_day_id <= v.end_day_id

                       AND i.submit_time_id >= v.start_time_id

                       AND i.submit_time_id <= v.end_time_id

               AND i.session_id IS NULL)

              • 4. Re: Update a table with matching null values



                Error is Clear ORA-01427: single-row subquery returns more than one row


                your select  criteria should return single value.  if you wanted to do multiple value,multiple column update you have to use loop for that.

                  When I run into stuff like this and it isn't obvious why there are multiple rows, I'll run the select into two listings, with and without the distinct, and sorted, with no headings.  Then it is simple to diff the two, and the answer usually becomes quite obvious.
