VHDL Case/When: multiple cases, single clause


Tag : development , By : Sharad

seems to work fine You can separate multiple choices with the "pipe" or bar symbol. The proper syntax for your example is:
CASE res IS
  WHEN "00" | "01" => Y <= A;
  WHEN "10" => Y <= B;
  WHEN "11" => Y <= C;
  WHEN OTHERS => Y <= 'X';
END CASE;

OVER clause. How to order by multiple columns within a CASE clause?

I think the issue was by ths following , You can repeat the case statement in the row_number() partitioning clause:
SELECT TOP(50)
        ROW_NUMBER() OVER (ORDER BY (CASE WHEN @OrderBy = 'Total' THEN SUM(LastMonthViews) ELSE SUM(LastMonthViews) END) DESC,
                                    (CASE WHEN @OrderBy = 'Total' THEN SUM(TotalViews) ELSE SUM(LastMonthViews) END) DESC
                          ) AS Position
    ,SUM(Albums.TotalViews) AS TotalViews
    ,SUM(Albums.LastMonthViews) AS LastMonthViews
FROM Albums;

Oracle SQL IN-clause over multiple columns

I hope this helps . I am stumbling over a problem in oracle SQL which I can't solve on my own, so I hope you guys can help me out. I am trying to filter for multiple IDs in multiple columns, each ID can occur in at least 1 column. This is what I have achieved so far: , That is not possible. An alternative would be this:
with t
as
( select '1SP563' v from dual
  union all
  select 'T6R840' v from dual
  union all
  select 'FF764P' v from dual
  union all
  select 'T753RM' v from dual
  union all
  select '54T56A' v from dual
  union all
  select '4386HA' v from dual
  union all
  select '667R44' v from dual
)
select name, ident1, ident2, ident3, ident4, ident5, ident6, last_modified
from   tomis_rep.t_fact_fertigungen_comp fc
join   t
on     t.v in (ident1, ident2, ident3, ident4, ident5, ident6)
order
by     last_modified desc
select name, ident1, ident2, ident3, ident4, ident5, ident6, last_modified
from   tomis_rep.t_fact_fertigungen_comp fc
join   ( select column_value v
         from   table(sys.dbms_debug_vc2coll('1SP563', 'T6R840', 'FF764P', 'T753RM', '54T56A', '4386HA', '667R44'))
       ) t
on     t.v in (ident1, ident2, ident3, ident4, ident5, ident6)
order
by     last_modified desc

passing multiple values in the case statement of where clause in oracle

will help you I need to get input from the user which will be passed to the query and compared with the existing value AA. If it is AA then the ABC schema will be selected. , Here is a correct way to use CASE in the WHERE clause.
...
and case &user_input when 'AA' then case when a.table_owner in ('ABC', DEF') then 1 end
                     else           case when <your other conditions here>   then 1 end
    end
    = 1

Multiple values in case statement used as right operand of where clause sql oracle

Does that help I think, it should be enough to change = sign to >= in the condition and add another one to exclude the current date:
select field1, field2... from table 
 where date >= (
       case when TO_CHAR(TRUNC(sysdate), 'DY') = 'MON' then TRUNC(sysdate - 3)        
           else (TRUNC(sysdate-1)) END)
   and date < TRUNC(sysdate);
