CASE..WHEN &a THEN decode(instr(colA,'-') 1,colA,......

Using CASE within a function I wish to apply a second level of criteria within the CASE statement, something along the lines of the following:
CASE upper(option_in)
WHEN 'P' THEN decode(instr(value_in,'-')>1,value_in,plan_b)
WHEN ...
Looks nifty but doesn't work. Any suggestions would be appreciated.
Thanks,
Dan

Why are you switching to DECODE? Just use CASE again:
case upper(option_in)
when 'P' then case
              when instr(value_in, '-') > 1 then value_in
              else plan_b
              end
when ...

  • Using case when statement or decode stament in where clause

    hi gems..
    i have a problem in the following query..
    i am trying to use case when statement in the where clause of a select query.
    select cr.customer_name || ' - ' ||cr.customer_number as cust_name,
    cr.salary as salary
    from customer_details cr
    where (case when '>' = '>' then 'cr.salary > 5000'
    when '>' = '<' then 'cr.salary < 5000'
    when '>' = '=' then 'cr.salary = 5000'
    else null
    end);
    the expression in the when clause of the case-when statement will come from UI and depending on the choice i need to make the where clause.
    thats why for running the query, i have put '>' in that place.
    so the original query will look like this(for your reference):
    select cr.customer_name || ' - ' ||cr.customer_number as cust_name,
    cr.salary as salary
    from customer_details cr
    where (case when variable = '>' then 'cr.salary > 5000'
    when variable = '<' then 'cr.salary < 5000'
    when variable = '=' then 'cr.salary = 5000'
    else null
    end);
    so, in actual case,if the user selects '>' then the filter will be "where cr.salary > 5000"
    if the user selects '<' then the filter will be "where cr.salary < 5000"
    if the user selects '=' then the filter will be "where cr.salary = 5000"
    but i am getting the error "ORA 00920:invalid relational operator"
    please help..thanks in advance..

  • Case When instead of Decode

    Hi,
    How to convert this decode statements into CASE WHEN syntax
    phone_v := DECODE (c_rec.phone, NULL, NULL, DECODE ( is_it_number (c_rec.phone), 'F', DBMS_RANDOM.STRING ('a', LENGTH (c_rec.phone)), SUBSTR                                                             (DBMS_RANDOM.VALUE, 2, LENGTH (c_rec.phone))));
    thanks, Bcj

    That should be easiest written like the following :
    phone_v := DECODE (c_rec.phone
                      , NULL, NULL
                      , DECODE ( is_it_number (c_rec.phone)
                                , 'F', DBMS_RANDOM.STRING ('a', LENGTH (c_rec.phone))
                                , SUBSTR (DBMS_RANDOM.VALUE, 2, LENGTH (c_rec.phone))
                      );Is it ?

    You can, like this.

    try this in TOAD (replace each apostrophe of your sql by two apostrophes and add the starting and ending apostrophe to obtain a string)

    before using the string in VBA you must replace '' with the characters used to denote an apostrophe within apostrophes.
    I don't know nothing about VBA but I'm sure you'll know how to deal with it (an apostrophe within apostrophes).

    Group functions within a case are perfectly acceptable e.g.
    select sum(case when dummy = 'X' then '1' else min(dummy) end) from dual group by dummy
    SUM(CASEWHENDUMMY='X'THEN'1'ELSEMIN(DUMMY)END)
                                                 1There are other problems with your code...
    This looks wrong to me:
    min(<Expression>) or min(<Expression>)and you have a trailing comma after F in the group by clause.
    When you're having problems with a piece of SQL, It's useful to us if you post the error you are getting back, and your table structure and sample test data too if possible.

  • Decode or Case when statement

    Hi,
    I had a condition like
    test -table
    code - column
    t --> True
    f --> False
    I had two choices of writing query
    select decode(code,'t','True','False') from test;
    or
    select case code
    when 't' then 'True'
    else 'False'
    end
    from test;
    I want to know which one is best performance wise

    Wrong question really.. unless you writing a very tight loop doing 100's of 1000's of iterations using that type of conditional structure. And even then performance difference will not be that significant.
    The right question to ask is which one is more flexible and allows for the programmer that comes after you to read and understand and maintain your code. The CASE statement is in this regard, a lot better than a DECODE statement.
    Looking just at performance (which I suggest you do not do in isolation!!), I get mixed results using 10G Enterprise on different platforms (HP-UX vs SUN AMD) and operating systems (HP-UX vs Linux).
    On the former the DECODE is slightly faster. On the latter the CASE is slightly faster.
    Using the construct you've specified and doing a tight loop of a 100,000 iterations, the elapsed execution times are:
    HP-UX DECODE = 00:00:11.83
    HP-UX CASE = 00:00:12.32
    Linux/AMD DECODE =00:00:02.02
    Linux/AMD CASE = 00:00:01.84
    Obviosuly the CPU architecture plays a major role here. The AMD is considered as the best 64 CPU on the market. The HP-UX PARISC CPU (also 64bit), does not really compare raw performance wise. In addition this is a RISC CPU whereas the AMD CPU is I believe more CISC than RISC.
    Also interesting that the faster Sun AMD/Linux server I used for this benchmark is about 10% the price of the HP-UX server.. and about 5x faster ito raw speed as this benchmark showed. :-)
    An interesting exercise, but one with little real world value. Yes performance is important. But within PL/SQL, not to the level about debating whether a CASE or DECODE is faster. As I've mentioned, I believe the right question being one about readability and maintenance and not performance in this case.

  • CASE WHEN and DECODE

    Hi everybody,
    I have column in Discoverer like this one shown bellow:

    I want to make the same column with same functionality in OBI BMM. Is it possible? If it is possible, how to do that?
    Thanks in advance.

    As Sai said use Case stmt, your code will something like this
    Case Vrstapolise
    When 1 then 'Aktivno'
    When 4 then 'Kapitalisano'
    When 3 then

  • Using CASE WHEN THEN in dynamic Region Source area

    Hi all,
    I've been knocking my head around on this one for a while. Hope someone can show me some guidance. So far, the SQL Query in the Region Source works ok except after the THEN ''||'LINK'||'' . All text between the single quotes displays, and not just the hyperlink LINK. (My goal is to this simple test working, then go back an substitute in APP_ID, Page#, SESSION variables.) But I'm stuck with this problem. Searched the forum but this is as far as I got. Below is the code I'm using in the Region Source area. Perhaps a region attribute setting is needed but I'm unsure.

All text between the single quotes displays, and not just the hyperlink LINK.Not clear from this what the problem is. It appears to me that LINK is all of the "text between the single quotes". What do you mean by "all text"? (An example on apex.oracle.com is a good way to resolve such ambiguities...)
    The usual cause of unexpected results when the separation of concerns is breached and HTML is directly generated in report queries is having the Display Text As report column attribute wrongly set. Ensure it is Standard Report Column rather than the default Display as Text (escape special characters).

    I don't see the need for case statement here. Cant you just do this.

  • CASE WHEN THEN END

    Hello everyone,
    We have a function return Y or N.
    We have 2 table YTable YT and NTable NT.
    We are using UNION now.
    SELECT ONE.CL1
    FROM (
    SELECT CL1Y FROM YTable WHERE FUNCTION = 'Y'
    UNION
    SELECT CL1N FROM NTable WHERE FUNCTION = 'N') ONEWe are wondering to use CASE, WHEN, THEN, END.
    Is it possible or NOT?
    If you have a chance, please share your experiences.
    Thanks in advance,
    NY
    P.S.
    If you have more questions, please let us know.

    New Yorker,
    According to the given SQL block, the case function can not be used. You can use the case function with multiple table joins but you can only use the CASE WHEN ELSE END block for one column.
    If i got your question correct, that is my answer to your question.
    Regards.

  • Case when then not working

    In my database, two variable ID and time (varchar2) are there. I want to populate another variable using case when then by putting below conditon to convert like this
    But its not working. Can anyone help me
    if time =1 day then '1 Day'
    time > 2 days and time <=7 days then '2 to 7 days'
    time > 8 days and time <=15 days then '8 to 15 days'
    else 'not matching'
    ID Time
    12 1 days
    23 244 days
    12 2 days
    14 4 days
    15 6 days
    17 9 days
    select time,
    case WHEN
    UPPER(Time) = '1 DAY'
    THEN
    '1 day'
    WHEN
    UPPER(Time) Between '2 DAYS' and '7 DAYS'
    THEN
    '2 to 7 days'
    WHEN
    UPPER(Time) Between '8 DAYS' and '15 DAYS'
    THEN
    '8 to 15 days'
    ELSE
    'Not matching'
    END "update time"

    In my database, two variable ID and time (varchar2) are there. If you are storing Days in a column store it as NUMBER or INTERVAL data type. The way you have stored the value looks incorrect.
    What you can do is extract the number portion of your time column and apply the CASE statement. Something like this
    SQL> with t
      2  as
      3  (
      4  select 12 id, '1 days' time1 from dual union all
      5  select 23 id, '244 days' time1 from dual union all
      6  select 12 id, '2 days' time1 from dual union all
      7  select 14 id, '4 days' time1 from dual union all
      8  select 15 id, '6 days' time1 from dual union all
      9  select 17 id, '9 days' time1 from dual
    10  )
    11   select id,
    12          time1,
    13          case when time1 = 1              then '1 day'
    14               when time1 between 2 and 7  then '2 to 7 days'
    15               when time1 between 8 and 15 then '8 to 15 days'
    16               else 'not matching'
    17          end "update time"
    18     from (
    19              select id, to_number(regexp_substr(time1, '^[[:digit:]]*')) time1
    20                from t
    21          )
    22  /
            ID      TIME1 update time

  • Case-when-then logic in join condition

    Is it possible to implement case when then logic in join condition?
    Instead of:
    INGRP1.COL1 = INGRP2.COL1 (+)
    something like:
    case
    when INGRP1.COL2 IS NULL
    then INGRP1.COL1 = INGRP2.COL1 (+)
    else INGRP1.COL3 = INGRP2.COL3 (+)
    end
    expression builder for join condition.
    Any help much appreciated.

    Hi Kaiser,
    this is my variant
    1) join first table with second table twice (define two input group in join, include second table in mapping twice and map them to appropriate join group)
    INGRP1.COL1=INGRP2.COL1(+) and INGRP1.COL3=INGRP3.COL3(+)
    2) after join calculate attributes from second table with expression like
    case when COL2 IS NULL the INGRP2_ATTR else INGRP3_ATTR end
    Maybe anyone has a better solution...

    Oleg
