Decode in where claus with date comparasion

hi
i m using this query can we compare date in decode function in where claue if yes how
SELECT PPA.START_DATE,
PPA.END_DATE
FROM pa_project_assignments PPA,
PA_CONTROL_ITEMS PCI
WHERE DECODE(PPA.START_DATE < PCI.ATTRIBUTE1,PCI.ATTRIBUTE1,PPA.START_DATE) BETWEEN (PCI.ATTRIBUTE1) AND (PCI.DATE_REQUIRED)
AND PPA.END_DATE BETWEEN (PCI.ATTRIBUTE1) AND( PCI.DATE_REQUIRED)
AND PPA.PROJECT_ID=PCI.PROJECT_ID

This works.
SELECT * FROM emp
WHERE
CASE WHEN hiredate < SYSDATE THEN
hiredate
ELSE SYSDATE
END BETWEEN SYSDATE-10000 AND SYSDATEIn your CASE
SELECT PPA.START_DATE,
PPA.END_DATE
FROM pa_project_assignments PPA,
PA_CONTROL_ITEMS PCI
WHERE
case when PPA.START_DATE < PCI.ATTRIBUTE1 then
PCI.ATTRIBUTE1
else
PPA.START_DATE
end  BETWEEN PCI.ATTRIBUTE1 AND PCI.DATE_REQUIRED
AND PPA.END_DATE BETWEEN  PCI.ATTRIBUTE1 AND PCI.DATE_REQUIRED
AND PPA.PROJECT_ID=PCI.PROJECT_IDCheers!!!

  • Using decode in where clause with user defined function

    Hi,
    I have a below query which is failing as the function in the decode taking all cust_account_id as input parameter instead of the one which satisfies the condition in the inner query.So please provide a solution how can i pass only the selected one.
    SELECT hca.cust_account_id
    FROM hz_cust_accounts hca
    WHERE hca.org_id=FND_PROFILE.value('ORG_ID')
    AND hca.cust_account_id = (SELECT DISTINCT hcasa.cust_account_id
    FROM hz_cust_acct_sites_all hcasa
    WHERE hcasa.cust_account_id =hca.cust_account_id
    AND hca.org_id = hcasa.org_id)
    AND DECODE (hca.status , 'A', xx_ar_cust_audit_pkg.get_ship_to_order_type(hca.cust_account_id)) IS NOT NULL
    Thanks,
    Abhilash

    I'm having to guess without access to your tables, but I think changing the IN to a join should produce the same results. The JOIN should be evaluated before applying the WHERE clause, so this may resolve your problem.
    SELECT hca.cust_account_id
    FROM   hz_cust_accounts hca
           INNER JOIN hz_cust_acct_sites_all hcasa
           ON    hcasa.cust_account_id = hca.cust_account_id
           AND   hca.org_id = hcasa.org_id
    WHERE  hca.org_id = FND_PROFILE.value('ORG_ID')
    AND    DECODE (hca.status , 'A', xx_ar_cust_audit_pkg.get_ship_to_order_type(hca.cust_account_id)) IS NOT NULLAlternately, you could next part of the query and break the DECODE into the parent so it is evaluated after the inner query. This is likely uglier from a performance standpoint, though:
    SELECT cust_account_id
    FROM
    SELECT hca.cust_account_id, hca.status
    FROM   hz_cust_accounts hca
    WHERE  hca.org_id=FND_PROFILE.value('ORG_ID')
    AND    hca.cust_account_id = (SELECT DISTINCT hcasa.cust_account_id
                                  FROM   hz_cust_acct_sites_all hcasa
                                  WHERE  hcasa.cust_account_id =hca.cust_account_id
                                  AND    hca.org_id = hcasa.org_id)
    WHERE DECODE (status , 'A', xx_ar_cust_audit_pkg.get_ship_to_order_type(cust_account_id)) IS NOT NULL;

  • Where clause with time stamp

    Hii,
    I have an issue with using where clause with time stamp. My requirement is to
    select * from driver_on_policy
    where last_change_datetime = '2001-03-06 19:00:06'
    date is in this form 6/3/2001 7:00:06 PM
    thnks
    sam

    If you want to use '6/3/2001 7:00:06 PM', then
    where last_change_datetime = to_timestamp('6/3/2001 7:00:06 PM','DD/MM/YYYY HH:MI:SS PM')If you can use a literal string in ANSI standard YYYY-MM-DD HH24:MI:SS format, then just
    where last_change_datetime = timestamp '2001-03-06 19:00:06' (That 'DD/MM' might need to be switched around to 'MM/DD' if you are in America.)

  • Where clause in Data Block

    I'm running Forms 6i client/server.
    I have defined a where clause in the Property Palette for a Data Block.
    What I like to do is to extend the where clause with a subquery, but
    how can this be done? I mean, should I put the code in a trigger, which trigger?
    Regards
    Roar

    simple where clause with sub_query
    My block has name is dc_gmod. In the where pallete I put the text (and the all is work good!!!):
    exists
    select 1 from ttt.xxxxx_table v
    where (dc_gmod.cd_gmod = v.cd_gmod)
    and
    (instr(:fst.tmp_nm,cd_place,1) > 0
    or
    cd_place IN
    (select U_UNIT from ttt.xxxxxxxxx_tabe
    where RG_U = :QA.RG_UNIT_RUN
    AND SID = :QA.SID
    AND SERIAL# = :QA.SERIAL
    1.The dc_gmod.cd_gmod - is full name my block_name and item_name.
    2. The ttt.xxxxx_table is full name of my table what is source for block dc_gmod

  • Where clause with a combination of And and Or statements - Basic question

    Hi,
    I have a where clause with a combination of And and Or statements... May I know which one would run first
    Here is the sample
    WHERE SITE_NAME = 'Q' AND ET_NAME IN ('12', '15') AND TEST_DATE > DATE OR SITE_NAME = 'E' AND ET_NAME IN ('19', '20')
    can you please explain how this combination works
    Thanks in advance

    Hi,
    This reminds me of a great story. It's so good, it probably didn't really happen, but it's so good, I'm going to repeat it anyway.
    IBM once had an "executive apptitude test" that they would give to job applicants. There were some questions you might call general knowlege or trivia questions, and each question had a weight (for example, answering an unimportant queestion might score one point, an important question might be 5 points.) One of the questions was "What is the standard width of a mobile home?", and the weight of the question was -20: answering the question correctly did serious harm to your score. The reasoning was that the more you knew about mobile homes, the less likely you were to be their kind of executive.
    Now, as to your question, the correct answer is: I don't know. I don't want to know. Mixing ANDs and ORs without grouping them in parentheses is a really bad idea. Even if you get it right, it's going to confuse the next person who has to look at that code. Use parentheses to make sure the code is doing what you want it to do.
    If you really want to find out, it's documented in the SQL language manual. Look up "Operators, prcedence"
    http://docs.oracle.com/cd/E11882_01/server.112/e26088/operators001.htm#sthref815
    You can easily do an experiment, using scott.emp, or even dual, where
    WHERE  (x AND y)
    OR      zproduces different results from
    WHERE   x
    AND     (y OR z)

  • How can I pass multiple condition in where clause with the join table?

    Hi:
    I need to collect several inputs at run time, and query the record according to the input.
    How can I pass multiple conditions in where clause with the join table?
    Thanks in advance for any help.
    Regards,
    TD

    If you are using SQL-Plus or Reports you can use lexical parameters like:
    SELECT * FROM emp &condition;
    When you run the query it will ask for value of condition and you can enter what every you want. Here is a really fun query:
    SELECT &columns FROM &tables &condition;
    But if you are using Forms. Then you have to change the condition by SET_BLOCK_PROPERTY.
    Best of luck!

    ,emp.name
    ,emp.email
    ,emp.salesrep_number
    ,comp.name
    ,gs.srp_goal_header_id
    ,gs.status_code
    ,gs.start_date
    ,gs.end_date
    from g2c_goal_shr_emp_assignments_v emp
    ,jtf_rs_salesreps rs
    ,xxg2c_srp_goal_headers_all gs
    ,cn_comp_plans_all comp
    where 1 = 1
    and rs.salesrep_id = gs.salesrep_id (+)
    and gs.comp_plan_id = comp.comp_plan_id (+)
    and gs.period_year (+) = :1 -- :1 p_fiscal_year
    How can I generate a where clause with outer join : gs.period_year (+) = :1 ? Will I get '(+)=' from get(OAViewObject.CRITERIA_CONDITION)?
    thanks
    Lei

    If you are using SQL-Plus or Reports you can use lexical parameters like:
    SELECT * FROM emp &condition;
    When you run the query it will ask for value of condition and you can enter what every you want. Here is a really fun query:
    SELECT &columns FROM &tables &condition;
    But if you are using Forms. Then you have to change the condition by SET_BLOCK_PROPERTY.
    Best of luck!

  • No output for XML Publisher Report using CASE/DECODE in Where Clause

    Hi,
    I've a business requirement to modify an existing report which has two input parameters,
    -> p_statcode (Closed Status) which can have values 'Y' or 'N'
    -> p_overdue (Overdue Flag) which can have values 'Y' or 'N'
    The Overdue Flag is an evaluated column having values of Y/N and it is evaluated as follows,
    ONTF_MOD_VAL(NVL (
                                         (TRUNC (SYSDATE)
                                          - (TO_DATE (oe_order_lines.attribute18,
                                                      'DD-MON-RRRR')
                                             + TO_NUMBER (fnd_lookup_values.meaning))),
                                         0
                            overdue_flagThe user requirement now is they needs to be a third option for parameter p_overdue called ALL,
    passing which the output should include records having
    p_statcode is Y ELSE p_statcode is N AND p_overdue is Y OR p_overdue is N
    In other words records having both Y and N vlaues for Overdue Flag have to be returned irrespective of the value given to Closed Status.
    Original where clause in the Data Definition file is as follows,
    WHERE Closed_Status = nvl(:p_statcode,Closed_Status)
                       AND overdue_flag = nvl(:p_overdue,overdue_flag)My modified code is as follows,
    WHERE   Closed_Status = NVL (:p_statcode, Closed_Status)
             AND overdue_flag = (CASE
             WHEN :p_overdue = 'Y' THEN 'Y'
             WHEN :p_overdue = 'N' THEN 'N'
             ELSE overdue_flag
             END)
    OR
    WHERE   Closed_Status = NVL (:p_statcode, Closed_Status)
             AND overdue_flag = DECODE (:p_overdue, 'Y', 'Y', 'N', 'N',overdue_flag)Both approaches have the same problem.
    The output is in EXCEL format. The modified query works fine for p_overdue as Y or N but when p_overdue is passed as ALL it returns an empty EXCEL sheet with just the report output column headers.
    Any help as to why this is the case ?? What is wrong in my approach ?
    Regards,
    Vishal

    not clear about p_overdue = ALL
    which values needed for p_overdue = ALL ?
    try smth like
    WHERE   Closed_Status = NVL (:p_statcode, Closed_Status)
    AND (
       overdue_flag = DECODE (:p_overdue, 'Y', 'Y', 'N', 'N',overdue_flag) and :p_overdue != 'ALL'
       or
      :p_overdue = 'ALL' and (overdue_flag = 'Y' or overdue_flag = 'N')
    )for overdue_flag which has more then 'Y', 'N' values
    if overdue_flag only in ('Y','N') then
    WHERE   Closed_Status = NVL (:p_statcode, Closed_Status)
    AND (
       overdue_flag = DECODE (:p_overdue, 'Y', 'Y', 'N', 'N',overdue_flag) and :p_overdue != 'ALL'
       or
      :p_overdue = 'ALL'
    )

  • Where-clause for date-string

    Hi specialist's,
    i have a simple question about a select, but I think I do not see the forrest becaus of too many trees ...
    I have a table where timestamps are stored in seconds-since-epoch.
    I select a human readble format with this statement:
    select to_char(DATE '1970-01-01' + TRXTIMESTAMP / (24*3600*1000), 'DD-MM-YYYY HH24:MI:SS')  as timestamp from txlog;
    TIMESTAMP
    19-10-2013 09:31:27
    19-10-2013 09:31:27
    19-10-2013 09:31:27
    Now I want to filter i.e. for dates of 19-01.... 
    My first try was this:
    select to_char(DATE '1970-01-01' + TRXTIMESTAMP / (24*3600*1000), 'DD-MM-YYYY HH24:MI:SS')  as timestamp from txlog
      where timestamp like '19-%'
    Result:
    ORA-00904: "TIMESTAMP": invalid identifier
    My next try was this:
    select to_char(DATE '1970-01-01' + TRXTIMESTAMP / (24*3600*1000), 'DD-MM-YYYY HH24:MI:SS')  as timestamp from txlog
    where 1 like '19%'
    Result: 0 rows!
    If I change this to
    ... where 1 like '%'
    I get all rows.
    What is wrong with my selects ???

    Firstly, why not store timestamps as timestamps?
    Anyway, Your first select refers to the alias 'timestamp' which is only accessible in an outer query, not from within the where clause.
    Try
    Select * from (
    select to_char(DATE '1970-01-01' + TRXTIMESTAMP / (24*3600*1000), 'DD-MM-YYYY HH24:MI:SS')  as timestamp from txlog
    where timestamp like '19-%';
    But timestamp is not a good choice for an alias, as it is a keyword.
    Your second select is obvious - the number 1 will never be like '19%', but it will work
    in the third select: as 1 is indeed like '%' (anything).

  • Creating dynamic where clause with string delimiter " ; "

    hi...
    i need a solution for complex problem like, 1. start_date IN date,
    end_date IN date,
    shift_type IN varchar2
    i will get shift_type as "first_shift" or "first_shift;second_shift" or "first_shift;second_shift;third_shift" ....etc any combination. where fist & second & third shits are nothing but 1 , 2 , 3. i need to find out data between start_date and end_date in combination of shifts ( may be 1;2 or 1;3 or 1;2;3 or 2;3 ...etc) . now i need to write this code in dynamic where clause ...i tried in different ways...but not succeeded. can anybody guide me step by step...or with script.
    NOTE: there is a table called "shift" with data like
    shift_type shift_mode
    1 first_shift
    2 second_shift
    3 third_shift

    Hi,
    Whenever you have a problem, post a little sample data (CREATE TABLE and INSERT statements) and the results you want from that data.
    If the question involves parameters, give a few different sets of parameters and the results you want for each set, given the same sample data.
    It's unclear that you need dynamic SQL at all.
    If shift_type is a variable, that can be either a single value or a ;-delimited list (such as '1;3'), you can compare that to a column called shift_column like this:
    WHERE        ';' || shift_type   || ';'     LIKE
           '%;' || shift_column || ';%'No dynamic SQL or PL/SQL required.
    If you really do want to use dynamic SQL, these two pages should gives you some ideas:
