Case statement in where clause

Hello

I have to write the following query using the value of the l_var variable in the case statement

How do I get there?


Select col3

of the test

where col1 = "A".

and the case

When l_var = "Y' and col2 = 'B '.

When l_var = 'n' and col2 = 'C '.

end;

In your expression

case

When l_var = 'Y' and col2 = 'B '.

When l_var = ' only then col2 <> 'B '.

end;

you try to return a Boolean (True or False) value like 'then' value of the CASE statement.

Values Boolean are not an Oracle SQL data type, you cannot use the true/false result of col2 = 'B' as an expression. This is why it does not work.

It's even more simple as:

Select col3

of the test

where col1 = "A".

and ((l_var = «Y» et col2 = «B») or (l_var = ' no and col2 <> 'B'))

If you really want a CASE statement then:

Select col3

of the test

where col1 = "A".

and the CASE WHEN l_var = 'Y', THEN CASE WHEN col2 = 'B', 1 ELSE 0 END

WHEN l_var = ' no CASE THEN WHEN col2 <> 'B', 1 ELSE 0 END

END = 1

    Hi all

    Hello

    It should be something like this:

    AND CASE
  WHEN 'false'='true' THEN (select id_reserv from demande_livraison where id_env_dep>='-1')
  ELSE id_reserv
     END = id_reserv

    The subquery must return a line

    But I think that it is better to write your query in the form:

    SELECT id_reserv,
     concat(nom,concat('_',indice)) as nom,
     libelle,
     num_lot,
     resa_keyword1,

     (SELECT login from utilisateur u where u.id_util=r.id_util) AS nom_util,
     (SELECT nom from environnement e where e.id_env=r.id_env_act) AS nom_env,
     (SELECT count(*) from reserv_comp rc where rc.id_reserv=r.id_reserv) AS nbComp,
     (SELECT count(*) from reserv_modif mc where mc.id_reserv=r.id_reserv) AS nbModif

     WHERE r.nom NOT LIKE 'RESERV_LOT_%'
     AND id_util='1'

                      or
                      ( 'true'= 'true' and id_reserv=id_reserv
                      )
                   )

  • Once again... Help... CASE in the WHERE clause...!

    Hi all

    I posted the question about CASES where the condition. It is one of the changes.

    The first condition was, if the Individual is 01 extraction then all the values of the table where the column of FLG = 'Y '. If the Individual is 02 and then extract all the values of the table where the column of FLG = ' no or NULL. Here, INDI is the setting.

    Select count (*) from cntl
    XYZ
    where NVL(FLG,'N') = decode(INDI,'01','Y','02','N');

    Now the chnages is, if the Individual is 01 and then extract all the values in the table where FLG colum = 'Y '. If the Individual is 02 and then extract all the values in the table, including ('Y', ' n, NULL). no need to put the filter of the FLG columns in which contion.

    It's not just...

    select count(*) into cntl
from xyz
where NVL(FLG,'N') = decode(INDI,'01','Y','02',NVL(FLG,'N'));

    Or shorter:

    select count(*) into cntl
from xyz
where NVL(FLG,'N') = decode(INDI,'01','Y',NVL(FLG,'N'));

    If you are happy for 01 retreat flg of Y and any other value fold everything.

  • Help... CASE in the WHERE clause...!

    Hi all

    I need help in the following condition. I am passing the parameter say INDI. the value of INDI can be 01 or 02

    I am retriving count in a table. say,

    DECLARE
    CNTL varchar2 (5);
    BEGIN

    Select count (*) from cntl
    XYZ
    where FLG = CASE WHEN INDI = '01', then 'Y' END;

    dbms_output.put_line (cntl);
    END;

    the FLG column can contain the value "Y" or "n" or NULL. If I run the above code, it gives me a count for these lines where FLG = 'Y' for INDI 01. But if I spend INDI = 02, it should give me account for these lines that has FLG = ' not and NULL.

    If I say where FLG = CASE WHEN INDI = '01' and then 'Y' ELSE ' no END; then he'll give me an account for these lines that has FLG = ' don't, but here I want County to FLG = 'n' and FLG = NULL, if I spend INDI = 02

    I am not able to determine how I can achieve this... 
    select count(*) into cntl
  from xyz
 where NVL(FLG,'N') = CASE WHEN INDI = '01' THEN 'Y'
                     WHEN INDI = '02' THEN 'N'

  • using case when statement or decode unfavorable in where clause

    Hi the gems...

    I have a problem in the following query...
    I try to use when case statement in where clause of a select query.


    Select cr.customer_name. ' - ' || CR.customer_number as cust_name,
    CR. Salary salary
    of customer_details cr

    the expression in the when clause of the statement of the case, when comes from HQ and according to the choice I have to make the where clause.
    That is why, for the execution of the query, I put ' > ' in this place.

    If the original query will look like this (for reference):

    Select cr.customer_name. ' - ' || CR.customer_number as cust_name,
    CR. Salary salary

    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 '.

  • Case statement in a WHERE clause

    Gurus,

    Im trying to avoid Union of several select statements using a CASE inside a WHERE clause. When the parameter is defined as "What's new" it is advisable to use a code and for "Update Items" another condition.

    Having a problem with the following... I know that BOX in WHEREs instructions are allowed only can not make it work for this one.

    and case  when 'New Items' = 'xxx' --p_item_status 
         then  msi.creation_date = msi.last_update_date
      when 'Updated Items' = 'bbb' --p_item_status  
         then  msi.creation_date != msi.last_update_date
      else 1=1
end; 
    Points for correct and helpful answers!

    Hello

    The great thing about CASE expressions, is that they allow you to use a login IF-THEN-ELSE in the clause SELECT, the ORDER BY clause or anywhere else. The WHERE clause has its own way to IF-THEN-ELSE logic, so even if you can use a CASE expression in a clause WHERRE, it usually does not help anything. You can do somehting like this:

    WHERE     (     :p_item_status        = 'New Items'
     AND     msi.creation_date  = msi.last_update_date
     )
OR     (     :p_item_status        = 'Updated Items'
     AND     msi.creation_date  != msi.last_update_date
     )
OR     (     :p_item_status        NOT IN ( 'New Items'
                           , 'Updated Items'
                           )
     )

    This guess: p_item_status is not NULL.
    If: p_item_status can be NULL, and you want to include all the lines where it is, and then change the last condition to

    OR     ( NVL (:p_item_status, 'OK') NOT IN ( 'New Items'
                             , 'Updated Items'
                             )
     )

    I hope that answers your question.
    If not, post a small example of data (CREATE TABLE and INSERT, only relevant columns instructions), some values of the parameter and the expected results of these data for each value of the parameter.
    Explain, using specific examples, how you get these results from these data.
    Always tell what version of Oracle you are using.

    Furthermore, you might think to rearrange your table, so that you do not have 10 columns (rcresar_comm_code_01, rcresar_comm_code_02,...) that essentially do the same thing. The usual way to handle this kind of one-to-many relationship is to have all rcresar_comm_codes in a separate table, one per line, with a pointer to the table where you have them now.

  • Using a CASE statement in 'IN' where clause clause

    Hello

    I have a form that users see after they connect with a few items and they type or select values based on the element type. All reports in the application use these values of PAGE 1 in where clause to filter the lines.

    One of these question is "Quarter".  I have a group of radio buttons on the PAGE 1 on the P1_QTR point.

    I need to provide users a way to take the last 4, last 3, last 2 or current quarter and I need to dynamically build a clause WHERE the interactive report based on the selection in the form.

    I am trying to use the CASE as shown below and get the syntax error.

    AND QTR to (when BOX: P1_QTR = 'CURRENT' then ("T4"))

    When: P1_QTR = "LAST" then ("Q3")

    When: P1_QTR = 'LAST TWO' then ('Q3, "Q4")

    When: P1_QTR = 'LAST THREE' then ("Q2", "Q3,' T4 ')

    another ("T1", "T2", "Q3,' T4 ')

    END)

    How can I achieve this?

    Following a simple logic, try

    and QTR to

    (

    Select 'T4' double where: P1_QTR <> 'LAST '.

    Union of all the

    Select 'Q3' to double where: P1_QTR <> "in PROCESS".

    Union of all the

    Select "Q2" double where: P1_QTR not in ('CURRENT', 'LAST', "LAST TWO")

    Union of all the

    Select "Q1" double where: P1_QTR not in ('CURRENT', 'LAST', 'LAST TWO', 'THREE LATEST')

    )

    A basic concept that is important to understand - sliders aren't 'sets of results' (sets of data in memory). A cursor is a series of executable steps (see plans run to cursor). It's like a program. An extraction run the program and output data. In general, which is repeated until the cursor (aka program) is no longer found the corresponding lines.

    A ref cursor is a pointer or a handle for a such slider, passed to a caller, allowing the appellant to interface directly with this slider/program.

    The slider more effective to create a search would be one without superfluous code and predicates and filters. Consider the following approach - a beefier PL/SQL procedure, do not try and play little tricks with SQL predicates in an attempt to create one (and probably not optimal) SQL.

    (not tested/compiled code)

    create or replace procedure SearchAddress(
  town     IN SEARCHADDRESS.TOWN%TYPE,
  street   IN SEARCHADDRESS.STREET%TYPE,
  postcode IN SEARCHADDRESS.POSTCODE%TYPE,
  refCur out ref_cursor
) is
  curHandle integer;
  res integer;
  searchSQL varchar2(1000);
begin
  -- create base query
  searchSQL := 'select searchaddress_pk from searchaddress where 1 = 1 ';

  -- add dynamic predicates as needed
  if town is not null then
    searchSQL := searchSQL || 'and town = :town';
  end if;

  if street is not null then
    searchSQL := searchSQL || ' and street = :street';
  end if;

  if postcode is not null then
    searchSQL := searchSQL || ' and postcode = :postcode';
  end if;

  -- create a DBMS_SQL cursor
  curHandle := DBMS_SQL.open_cursor;
  DBMS_SQL.parse( curHandle, searchSQL, DBMS_SQL.NATIVE );

   -- bind the dynamic bind variables added as predicate values
  if town is not null then
    DBMS_SQL.Bind_Variable( curHandle, 'town', town );
  end if;

  if street is not null then
    DBMS_SQL.Bind_Variable( curHandle, 'street', street );
  end if;

  if postcode is not null then
    DBMS_SQL.Bind_Variable( curHandle, 'postcode', postcode );
  end if;

  -- execute cursor (to create the cursor program) and pass it back as a ref cursor
  res := DBMS_SQL.Execute( curHandle );
  refCur := DBMS_SQL.To_RefCursor( curHandle );
end;

  • A CASE statement with additional where clause

    Hi all

    I need assistance in which this obligation clause

    Table:-balance_table

    Columns:-balance_type, balance_amount, balance_month, budget_name

    balance_type column had given 'Real' OR 'Budget '.

    Now I am trying to extract data such as: if: entered_month is Mar-2009 then before and including Mar-2009 will show real balance sheet Date and after Mar-2009 will show budget data.

    It works fine, I need to add a condition more restrict the budget name, there are several budget_name in the table for balance_type = 'Budget '.



    SELECT SUM (balance_amount), balance_type, balance_month
    OF balance_table
    WHERE balance_type =
    (CASE
    WHEN balance_month < =: entered_month
    THEN 'real '.
    ANOTHER 'Budget '.
    END
    )
    AND budget_name = 'BUDGET1.
    Balance_type GROUP, balance_month

    Stated above is erroneous because ' AND budget_name = ' BUDGET1 "clause restricts the set of data."

    Please help in contrcuting where clause 1) to sort the data according to Budget/actual and 2) for specific budgets, so budget_type = Budget

    Thank you
    Bobin

    That should do it.

    SELECT SUM (balance_amount),
       balance_type,
       balance_month
FROM balance_table
WHERE (balance_type = 'Actual'
       and balance_month <= :entered_month
      )
or (balance_type = 'Budget'
    and balance_month > :entered_month
    and budget_name = :entered_budget_name
   )
GROUP BY balance_type,
         balance_month
ORDER BY 2

    See you soon

  • Case instructions within a Where clause clause

    Hello group,

    I know this has been asked several times, but I do not enter simply to a tuition assistance box in a WHERE clause.  So I need help:

    My current WHERE the clause reads:

    A16. FULL_DATE between (SELECT (TRUNC (SysDate - 8)) From Dual) and (select (TRUNC (SysDate - 2)) double)

    However, I need to 'automate' a bit, based on the current time/day of the month.  I need my instruction box to say:

    (Case when to_char (sysdate-3, 'mm') <>to_char (sysdate, 'mm')

    then the a16. FULL_DATE (between SELECT (trunc (ADD_MONTHS ((LAST_DAY(SysDate-3)),-1)+1) and (SELECT (add_months (trunc(SysDate-2)-1)) of double)))

    Of another a16. FULL_DATE between (SELECT trunc (ADD_MONTHS ((LAST_DAY (SysDate)),-1)+1) From Dual) and (select (TRUNC (SysDate - 2)) From Dual)

    However, I have an error on "Else".  Can someone explain what is the problem and how to fix it?  I tried both 'then' and 'Else' syntax and both will run individually.  So I'm quite sure that he does not like my CASE statement in general.

    In advance, thank you for your help.

    Don

    I can't tell what your business logic, so here's a simple example of an instruction box in the where clause:

    SQL > select *.
    2 double
    3 where dummy = case when extracted (sysdate months) = 9 then 'W '.
    4 Once extracted (sysdate months) = 10 then 'X '.
    When 5 extract (month from sysdate) = 11 then 'Y '.
    6                      else 'Z'
    7                 end
    8;

  • How to set a null column in a where clause clause involving a statement box

    In oracle APEX, I a (selection list) element called: P32_STATUS. It contains two values of interest (for this discussion): 'Available' and 'checked '. In my report, I have a column called vc_status that contains two values: "Checkbox" and NULL. In my application I want to use a case statement in my where clause similar to the lines of

    where

    .

    .

    .

    AND (vc_status = CASE WHEN: P32_STATUS = "Checkbox" THEN : P32_STATUS )

    WHEN : P32_STATUS = 'Available' THEN NULL END)

    The 'box' filtering works but the filtering to try to vc_status the NULL value does not work. Can someone help me? Thank you!

    (P.S. My intuition says that there because I can not put vc_status = NULL, but I must say that vc_status IS NULL... However, I don't know how to do execution IS ZERO inside a CASE statement)

    Hello

    Your intuition is right...

    In Oracle NULL is a bit special:

    NULL = NULL is false

    NULL <> NULL is false

    Thus, instead of the parameter a NULL value in the CASE WHERE there is just set a value on the other side:

    NVL (vc_statut, 'Available') =: P32_STATUS

    That's all! Simple, clean and functional
