• Select with case statement and a formula of the IIR

  Hi, I was looking to get help regarding a statement writing box with a statement select statement all. I tried to reproduce a formula IIf access well that just wanted to check that the query I wrote is correct, any advice would be appreciated.

  [code]

  Select *.

  Of

  (

  Select name, month, duration, volume, time_spent, date1, date2,.

  -case when 'date' > = 'date1' then '1' other '0' end as departure,.

  inner join call_2 ON cd.name = cl.queue cl

  )

  )

  I want to know is where I have my ' select name, etc, I would change that to select * to make it easier instead of typing all the field_names outside, but I don't know how to do and also what follows is 2 IIF formulas from an access database for the start of the final case statements so I just wanted check I wrote it correctly.

  Hello

  Whenever you have any questions, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the results desired from these data.
  Explain, using specific examples, how you get these results from these data.

  If the output depends on what anyone outside the application itself (for example, when it is run) and then include a few different examples and the results you want of each given the same sample data. For example, "if I run on November 19, 2013, while the results should be... because... but if I run between November 21 and November 27, then the results should be... because...". »
  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

  DATE is not a function of Oracle; in fact, it's a terrible name for a column or function, because it blends with the DATE data type.

  In Oracle, the function SYSDATE returns the date and time, according to the clock on the database server.  So, SYSDATE can return a value as November 19, 2013 06:33:15.   If you want to midnight the same day (i.e., November 19, 2013 00:00:00) and then use TRUNC (SYSDATE).

  String literals (for example the string which consists 5 characters d, a, t, e, and 1) go inside the single quotes. Numbers and the names of columns only.

  If you want to include all the columns, more some calculated values, in a SELECT clause, then you must use a name table or alias before the *.  (See select_2 below.  To do this, assign the alias j to display online.)

  Maybe you wanted to say something like:

  Select *-it's select_1

  de)

  Select j. *-it's select_2

  , case when SYSDATE > = date1 then 1 or 0 end as departure

  , case when SYSDATE<= date2="" then="" 1="" else="" 0="" end="" as="">

  de)

  Select *-it's select_3

  of call_1 cd

  inner join call_2 ON cd.name = cl.queue cl

  ) j

  )

  ;

  As mentioned in a previous answer, you should be careful about the use of "SELECT *" in production code.

  In select_3, it would be better if you explicitly listed the columns you need.  It can improve efficiency and maintenance.  In this request, queue and the name will be always the same, so you probably don't want to include both of them in the result set, in any case.

  In select_1 and select_2, it is acceptable to use "SELECT *", assuming that select_3 is fixed.

  Moreover, there is no point in using subqueries here.  You can get the same results simply in a single query, without any subqueries.

  No, your SQL is not that.

  The select statement that you put online here, aside from being not not in brackets, is the selection of two values, but you can provide two values for the result column.

  Without knowing who the SQL statement, we can highlight only the obvious questions.

• Problem with CASE statements

  Hi all
  
  I have a calculation in a report of Discoverer Desktop with 29 instructions BOX and still 2 case statements more to add. The problem is that my report freezes and fails to run due to the excessive number of case statements. I need to put the 31 statemnts cases in the report, how do I do this? Is there another way to do it without causing the report to freeze?
  
  Below is part of my instructions box just to show you what I'm doing:
  
  CASE WHEN Ex = 'MM' AND THEN of OTHER NULL result (', ')
  CASES WHERE Ex = "PP" AND result IN (40,35,30,25) THEN NULL OTHERWISE
  CASE WHEN Ex = he's ' AND result IN (' a ',' B', 'C', d ') THEN NULL OTHERWISE
  -CASE WHEN Ex = 'IO' AND THEN of OTHER NULL result ('Distinction', 'Merit')
  -CASE WHEN Ex IN ('ZZ', 'WW', 'SS', 'KK') AND ('PASS', 'P') THEN to ANOTHER NULL result...
  
  The last statement should be BOX WHEN... THEN NULL OTHERWISE 1 END END END END...
  
  Help, please. Thank you.

  Hello
  You have reached the limit of characters in a calculation.

  Try to set into a single statement as follows:

  CASE WHEN Ex = 'MM' AND THEN of OTHER NULL result (', ')
  WHEN Ex = "PP" AND as a result (40,35,30,25) THEN NULL OTHERWISE
  WHEN Ex = he's ' AND result IN (' a ',' B', 'C', d ') THEN NULL OTHERWISE
  WHEN Ex = 'IO' AND THEN of OTHER NULL result ('Distinction', 'Merit')
  WHEN Ex IN ('ZZ', 'WW', 'SS', 'KK') AND ('PASS', 'P') THEN to ANOTHER NULL result...

  The last statement should be BOX WHEN... THEN NULL OTHERWISE 1 END

  Another option is to combine all the statements of NULL in a series of gold options like this:

  BOX WHEN
  (Ex = 'MM' AND the result in (', am')) OR
  (Ex = "PP" AND result IN (40,35,30,25)) OR
  (Ex = he's ' AND translated BY (' a ',' B', 'C', ')) OR
  (Ex = 'IO' AND as a result ('Distinction', "according to merit")) OR
  (Ex IN ("ZZ", "WW", "SS", "KK") AND result IN ('PASS', 'P')) THEN ANOTHER NULL...

• How to use the Substring function with Case statement.

  Hi all
  
  I have a requirement where I have to use the substring function on the ground for the report criteria.
  FOR EXAMPLE
  I branch domain name where I have all the information of the branch names, now some of the branch names are too large with an extension after the name.
  now I want substing it, but the length of characters varies for each branch.
  so is it possible where we use a box where we can define if the character of name plug exceed a value then he substing with this length.

  Try something like this:

  LENGTH WHEN CARTER (tablename. Branch_Name) > n THEN SUBSTRING (...) Of ANOTHER tablename. Branch_Name END

  where n is the number of characters that you want to start the break.

• [8i] Case statement generates ORA-00932: inconsistent data types

  Note: I work with a 8i database (Yes, he's old enough) and in this case, I have to deal with the types of data (e.g. TANK), I gives me to work with.
  
  I am trying to calculate the amount of time product expected between manufacturing steps. As I found out though, sometimes I get a negative value then subtract the date the previous step ends the date of that ongoing stage begins. Since it is generally impossible to start a later stage before a previous step (imagine trying to screw a cap on a bottle that has no son Cup yet - it just may not happen), what I found is that sometimes two steps are started the same day and finished the same day (although not necessarily the day they started). This situation CAN occur when a person is two steps and connected to two steps at the same time, rather than log on to one, then the other. So what I need to do in these situations, is to replace the negative number by zero (I'll treat the stage as having no time-out).
  
  Some examples of data:
  (Note: the data set real is the result of a query and has about 200 K lines and columns more, but this should be representative enough to find a solution that works on my real application.)

  I know that I had errors in data type incompatible before with case statements in this particular 8i database, but I can't seem to understand why I'm getting one this time. I think it has something to do with the NULL value which may occur for last_step_finished. Also, if I change the case statement to:

  ,     CASE
            WHEN     start_dt - last_step_finished     < 0
            THEN     NULL
            ELSE     start_dt - last_step_finished  -- THIS LINE GENERATES THE ORA-00932 ERROR
       END     

  the query works fine. But, I'm not NULL, I 0. In the level of this request, I'll take the averages by item_id/step_nbr, and I want that 0 s to be included in the average. (NULL values, as far as I know, would be excluded. AVG(null,_1,_2) = AVG (1,2) = 1.5 NOT AVG (0,1,2) = 1).
  
  Thanks in advance!

  CASE requires that all expressions to be of the same type. Numeric data type code is 2, then that date produced different internal datatype 14:

  SQL> select dump(1) a,dump(sysdate) b,dump(sysdate - (sysdate - 1)) c from dual;
  
  A                  B                                   C
  ------------------ ----------------------------------- ------------------------------
  Typ=2 Len=2: 193,2 Typ=13 Len=8: 219,7,6,27,13,7,50,0  Typ=14 Len=8: 1,0,0,0,0,0,0,0
  
  SQL> 
  

  Case is supposed to process until the number, but it does not--a bug in some versions. Use explicit to_number:

  ,     CASE
            WHEN     start_dt - last_step_finished     < 0
            THEN     0
            ELSE     to_number(start_dt - last_step_finished)
       END                         AS days_in_queue

  Hello

  So, you don't want to ignore the whole when line stat! = 'E' (that ignores the single row with id = "3"). Put the condition ' stat = 'E' in the sill of the WHERE clause ignores line, so this isn't what you want.
  You want to just ignore the expression column. Put the same condition in a CASE expression that contols only this column.

  Here's one way:

  SELECT       id
  ,       MIN ( CASE
                   WHEN  stat = 'E'
                THEN     term
               END
             )          AS min_e_term
  FROM      dan_gr2
  GROUP BY  id
  ORDER BY  id
  ;

  I have problem with value NULL when the use CASE statement please help this question

  
  

  Table: digital_val

  case If c1 = "san2" then c2 B

  of digital_val

  I'm more curious why, when you select 2 rows, you expect a result of row?

  WITH digital_val

  AS (SELECT 1 AS 'Sno', 'San1"C1, c2 FROM DUAL 11)

  UNION ALL

  2 SELECT AS 'Sno', 'San2"C1, c2 FROM DUAL 22)

  SELECT CASE WHEN c1 is "San1" THEN END AS A c2.

  CASE WHEN c1 = "San2" THEN END AS B c2

  OF digital_val;

  With no other input, if you select 2 rows, you get 2 rows.  One of the other solutions use a max function, but is this really what you want, does not specify?

• How can I get the nested case statements to work with listagg?

  I have a statement below that does not work as I want it, here is my code:

  Select

  cases where o.personal_label is not null

  then

  listagg (cases where s.subcodevalue like '% MON %')

  then s.subcodevalue |' '|| o.personal_label

  of other s.subcodevalue

  end,': ')

  the Group (order of s.subcodevalue) as subcodevalue

  on the other

  listagg (s.subcodevalue,': ')

  the Group (order of s.subcodevalue) as subcodevalue

  end

  of mtm_styles_new s, order_mtm o

  where INSTR (o.extras, s.code) > 0

  and o.bodyfitting = s.bodyfitting

  and o.division = s.division

  and s.subcodevalue is not null

  and o.ORDER_MTMID = 'somevalue '.

  It should bring the following

  * MY TEST: RPP

  or the following if the first case is not completed:

  * MONDAY: RPP

  I get an error message saying 'missing keyword', but cannot make out where, can someone please help me here?

  The following works fine as long as it is not a nested case statement, but I need to nest the case statement:

  Select listagg (cases where s.subcodevalue like '% MON %')

  then s.subcodevalue |' '|| o.personal_label

  of other s.subcodevalue

  and o.division = s.division

  and s.subcodevalue is not null

  and o.ORDER_MTMID = 'somevalue ';

  Out alias 'subcodevalue as' the case at the end of the case body.

• Case statements with AND

  Hi all.

  I use a case statement to represent the values for different regions in a command prompt. I'm having some difficulties, with the values in the case statement. Here is an example of a simplified and shortened my code version.

  CASE

  WHEN 'Region '. "" Region name "="A"THEN"AMERICA ".

  WHEN 'Region '. "" Region name "= 'B' THEN 'CHINA '.

  WHEN 'Region '. "" Region name "= 'C' THEN 'EUROPE '.

  WHEN 'Region '. "' Name of the region ' = 'A' AND 'B' AND 'C' THEN 'GLOBAL '.

  END

  My error when I use it in my statement. The formula is accepted, however, all the values are displayed in my guest except 'GLOBAL '.

  How can I be able to assign a "GLOBAL"value in my guest? ".

  Jagadekara I think that you do not get the point. Any given row retrieved from a data source cannot have all three at one point values!

  AJ was trying to tell you, is that your CASE logic has no sense at all.

• Case statement with a select &amp; date in

  Hello everyone,

  This is my first discussion, so please bare with me.

  I am trying to write a case statement with a select statement that compares the dates.

  When I write an instruction box with a select statement in it compares everything but dates it works fine.  Once the date is there, he collapses.

  Here is a super simple example of what I'm trying to do, "b.in_serv_dt" is a date

  Select unit_no,

  case when ((sélectionnez b.in_serv_dt de b unit_dept_comp_main où a.unit_id = b.unit_id et b.in_serv_dt) > = 1 January 2012 "") then "everybody wins."

  When ((sélectionnez b.in_serv_dt dans l'unit_dept_comp_main b où a.unit_id = b.unit_id et b.in_serv_dt) < = 1 January 2012 "") then "Nobody wins".

  end

  of ottawa_unitmain_v one

  Any help would be greatly appreciated

  Thank you very much

  Hello

  your statement of formatting:

  Select unit_no
  case when ((select b.in_serv_dt
  of unit_dept_comp_main b
  where a.unit_id = b.unit_id
  and b.in_serv_dt
  ") > = JANUARY 1, 2012"
  ) and then "everybody wins."
  When ((select b.in_serv_dt
  of unit_dept_comp_main b
  where a.unit_id = b.unit_id
  and b.in_serv_dt
  )<=>
  ) and then "no winner".
  end
  of ottawa_unitmain_v one

  I see "partial conditions": <... and="" b.in_serv_dt="">> that have no meaning.
  I guess it's a kind of "typo" and I ignore them.
  If the statement is:
  Select unit_no
  case when ((select b.in_serv_dt
  of unit_dept_comp_main b
  where a.unit_id = b.unit_id
  ") > = JANUARY 1, 2012"
  ) and then "everybody wins."
  When ((select b.in_serv_dt
  of unit_dept_comp_main b
  where a.unit_id = b.unit_id
  )<=>
  ) and then "no winner".
  end
  of ottawa_unitmain_v one

  I guess that the "b select" retrieve one line, through the design of database (forced...)

  As already written: be careful with data types: avoid "implicit conversions" (when you compare different data types, Oracle has convert the data type of the other side, a side example: "mystring = mynumber" is transformed into 'TO_NUMBER (mystring) = mynumber', or 'mydate = mystring' translates mydate = TO_DATE (mystring, ) ")
  Even better: use explicit conversions, use explicit formats when necessary.
  Best: use no conversion on columns from the constants, but use the correct data type for the constant.

  With this in mind:
  Select unit_no
  case when ((select b.in_serv_dt
  of unit_dept_comp_main b
  where a.unit_id = b.unit_id
  ) > DATE = ' 2012-01-01'
  ) and then "everybody wins."
  When ((select b.in_serv_dt
  of unit_dept_comp_main b
  where a.unit_id = b.unit_id
  )<= date="">
  ) and then "no winner".
  end
  of ottawa_unitmain_v one
  But note that b.in_serv_dt EQUAL to 1 January 2012 (at 00:00:00) is OK for both WHEN the conditions; then the a "win."

  Now: the subselect statement is identical in the 2 options of the case... You could work differently: (I add the "ELSE" in case one line as NULL in_serv_dt;) I guess that an INNER JOIN is OK, maybe you need a LEFT OUTER JOIN (if some lines of A have no corresponding row in B)

  SELECT a.unit_no
  , CASE WHEN b.in_serv_dt > = DATE '' 2012-01-01
  THEN "everyone wins"
  WHEN b.in_serv_dt< date="">
  While "Nobody wins".
  ELSE ' who knows... ". »
  END who_wins
  Of ottawa_unitmain_v one
  INNER JOIN unit_dept_comp_main b
  ON a.unit_id = b.unit_id
  ;

• error with the case statement use what void const query

  Hi all.
  
  I have found the error in the result set, and then use subqueries and cases of declaration.
  
  Preparation for example.
  
  2 examples of tables creation.

  CREATE TABLE T1 
  AS
  (
      SELECT 1 ID , 1 F1 FROM DUAL
      UNION 
      SELECT 2 ID , 1 F1 FROM DUAL
      UNION 
      SELECT 3 ID , 1 F1 FROM DUAL
  ) ;
  
  CREATE TABLE T2
  AS
  (    
      SELECT 2 ID FROM DUAL
      UNION 
      SELECT 3 ID FROM DUAL
  ) ;
   

  This statement returns NULL in subquery

  SELECT 
  T1.ID, TT2.ID , TT2.ISBUG AS NO_BUG 
  FROM T1 
  LEFT JOIN
  (
  SELECT ID , -1 ISBUG FROM T2
  )TT2
  ON T1.ID = TT2.ID
  WHERE TT2.ID IS NULL
   

  But this statement (with operator CASE) does NOT return null in subquery

  SELECT 
   CASE  WHEN 1 = 1 THEN 1 END AS C1,
  T1.ID, TT2.ID , TT2.ISBUG 
  FROM T1 
  LEFT JOIN
  (
  SELECT ID , -1 ISBUG FROM T2
