• call the statement box inside the case statement

  I am writing a program which requires me to run a statement box inside another case statement. Although this sounds like a simple thing, I need to be able to call the case statement using a sequence structure, where s1 sends the true value to the case, s2, a fake. Then I need to record the results of this instruction box in a text file. Attatched is a simplified version of what I'm trying to do. Please note that the way my program runs may not call the case statement without using a sequence structure, two nesting box instructions is not feasible. I hope someone out there can help me because I was stuck trying to find this for awhile.

  Thank you

  Yes you can.  You just need to be smart.

  I don't think I can use a state machine to fix this.

  I think you probably can.

  With respect to your original post. What are these s1 and s2 are you talking about?  My opinion on the matter, it is that you want to select a case based on the values of several controls Boolean.  If this is correct, I do this:

  

  Build your Boolean controls in a table, convert the table number and insert it into the structure of your business.  No button pressed = 0, s1 = only 1, s2 = only 2 both = 3.   This works for Boolean values as much as you want and is an easy way to make a decision that depends on many entries.

I appreciate the information you provide when you answer these questions.  I always try to get the amount (from the same column) for 2 rows in different columns.  I tried the LAST_VALUE and LAG but it took a long time for the queries to run, I'm looking for another way to do the same.  I'm only using SQL to retrieve data.  I don't have the ability to create or insert.

  I looked the information above and the CASE statement to look like this:

  CASE

  THEN the RDP. ADEATH AS CURR_MONTH

  ON THE OTHER

  lao PDR. ADEATH AS MONTHS PREVIOUS

  But I'm now getting an "ORA-00905: lack of keyword" message.

  What I'm trying to do is to draw 2 lines 1 to 2014 / 11 and another for 2014 / 10.  The amount for the period 2014 / 11 should go in the current column and the amount for the period 2014 / 10 should go in the previous column.

  Before current assets management

  01 AB01 50.01 50.03

  ....

  If you want to give an alias for a column, then you can say "AS nome_alias" after that tell you what that is in this column.

  'AS nome_alias' applies to the entire column.  Cannot use 'alias_name' in the middle of an expression, for example, in the middle of a CASE expression, before the END keyword.

  If you want to have 2 separate output columns, curr_month and prior_month to your output, you must then 2 separate columns in your SELECT clause.  for example:

  SELECT pdr.branch

  pdr.asset

  CASE

  WHEN pdr.fiscal_year = 2014

  AND pdr.accounting_period = 11

  THEN pdr.depr

  END AS curr_month

  Thanks Frank. Really helps. But I have to write a sql statement

  But can you also specify, if I made a mistake in my code, or it's ok.

  There are no CASES reported in Oracle SQL.

  Oracle SQL has BOX expressions, but they only return a single value.  You cannot set 2 columns in the same expression BOX.

  Perhaps the best thing to do in pure SQL for you is to write a CASE expression, very similar to the CASE statement above, in a subquery and use the results of this in 2 separate expressions of BOX (very simple) in a Super application.

• Question of the CASE statement

  Is it OK to mix conditions inside the case statement? as for example:
  
  SUM (CASE WHEN b.SUPPLIER_NUM = 12345 AND c.VPN IN ('3245', '5345', '87894') THEN a.TRAN_AMT ELSE 0 END) SUMSPEND_MOS
  
  ???
  
  I put in parentheses between the two conditions?
  
  SUM (CASE WHEN (b.SUPPLIER_NUM = 12345 AND c.VPN IN ('3245 ', '5345', ' 87894')) THEN a.TRAN_AMT ELSE 0 END) SUMSPEND_MOS
  
  is this legal syntax? because its not complaining do not, but I want to just make sure that these things are good to use and the data comes right back.
  
  Thank you!

  Yes, you can do that. The conditions must be related somehow.

  I put in parentheses between the two conditions?

  SUM (CASE WHEN (b.SUPPLIER_NUM = 12345 AND c.VPN IN ('3245 ', '5345', ' 87894')) THEN a.TRAN_AMT ELSE 0 END) SUMSPEND_MOS

  You have no need, but if it helps you (or one who has to maintain the code) to understand it better, then go ahead. The cost can be one millisecond extra when the query is compiled (it will run everything as fast so be it), and the benefits can be enormous.

  I find that formatting code contributes much more clarity to have additional parentheses. Why not use something like that?

  SUM ( CASE
            WHEN (    b.SUPPLIER_NUM     = 12345
              AND  c.VPN           IN ('3245', '5345', '87894')
              )
        THEN a.TRAN_AMT
        ELSE 0
        END
      )          AS SUMSPEND_MOS
  

  If you have really complicated conditions, where you mix ANDS and ORs, then you should certainly use parentheses. It goes the same for the WHERE clause.

  is this legal syntax? because its not complaining do not, but I want to just make sure that these things are good to use and the data comes right back.

  The syntax is fine.
  If the data comes in good or bad is another matter. What data are, and what you mean by 'comes back good' (in other words, what results do you get off these data)?

• TDE is not "transparent" to the CASE statement

  Hello
  
  I have installed oracle (10) database with TDE. It works very well with almost all queries. But I have problems when I try to use the CASE statement.
  
  
  He comes to the table, I created:
  
  {color: #0000ff} create table t_test)
  col1 varchar (128)); {color}
  
  This query returns an empty result (as planned, because there is still no data in the table).
  
  {color: #0000ff} to select)
  When col1 = 'test' then 'test '.
  end) as Carter
  of t_test
  {color}
  I now encrypt the column with the following statement:
  
  {color: #0000ff} change alter table t_test (col1 encrypt using "AES256" without salt); {color}
  
  And try again the same statement:
  
  {color: #0000ff} to select)
  When col1 = 'test' then 'test '.
  end) as Carter
  of t_test
  {color}
  He now returns {color: #ff0000} ORA-00932 inconsistent data types: expected BINARY got {color} CHAR
  
  But if I try:
  
  {color: #0000ff} select *.
  of t_test
  {color}
  There is no errors (returns empty result, as expected).
  
  I tried even with data, with the same result.
  
  Could someone please tell me what I'm doing wrong here?
  
  Thank you.

  You touch the Bug 6262107 'ORA-932 of the CASE expression sought with encrypted column:

  Description:
  "ORA-932 incompatible data types: expected BINARY got TANK ' is triggered.
  on a query with a case expression sought on a column with TDE.

  for example:
  CREATE TABLE TDE_TEST (COL1 VARCHAR2 (1));
  INSERT INTO TDE_TEST VALUES('1');
  ALTER TABLE TDE_TEST CHANGE (COL1 ENCRYPT WITHOUT SALT);
  SELECT CASE WHEN COL1 = '1', THEN 'A' OF ANOTHER END 'B' OF TDE_TEST;
  ^
  ORA-00932: inconsistent data types: expected BINARY got TANK

  Workaround solution:
  Convert a simple case of the searched case expression expression.

  So, I updated the sql works:
  SQL > select (case col1
  2 when 'test' then 'test '.
  3 end) as Carter
  4 * of t_test
  /
  no selected line

  I hope this helps.

• Understand the CASE statement

  I got confused on this CASE

  (1) SELECT BOX WHEN 111 = "111" THEN 'YES' ELSE ' ' END OF THE DOUBLE - YES

  (2) SELECT CASE WHEN COALESCE (111 111) DOESN'T = "111" THEN 'YES' ELSE ' ' END OF THE DOUBLE - YES

  (3) SELECT CASE WHEN COALESCE (111, '111') = '111' THEN 'YES' IS ' ' END OF THE DOUBLE

  ORA-00932: inconsistent data types: expected NUMBER obtained TANK

  What exactly the things happening between 2 & 3. ' nt it implicitly convert as case 2 is because that in case 3, the first value is anyway not null as CAS2... This leads to confusion.

  I have read the Oracle documentation and there is an implicit data type conversion table. It also indicates that can be converted. There is always some confusion raised. Anyone could wrap this confusion?

  No, the function coalesce requires that all entries to be of the same data type because they are arguments of this function.

  Conversion of implicit data type occurs generally when things are compared with operators (as you do in examples 1 and 2.

  There is not many functions/procedures of this nature that the mixed data types and convert them for you.

  So, it is nothing to do with the CASE statements, it's in with him COALESCE function.  It is overloaded for particular data types, but it requires all arguments to be of the same data type.

  Well, it is interpretation since I'm guessing by your intention with the CASE statement.

  Do you mean

  CASE
  WHEN EXISTS
     (
        SELECT
           description
        FROM
           fnd_lookup_values flv

           flv.lookup_type  ='ZZCUS_SPER_ASSET_CODES'

     THEN
     (
        SELECT
           meaning
        FROM
           fnd_lookup_values flv
        WHERE
           flv.lookup_type  ='ZZCUS_SPER_ASSET_CODES'
        AND flv.description =sper.assettxt
     )
  END, 
  

  If yes then it is much better represented as

     (
        SELECT
           meaning
        FROM
           fnd_lookup_values flv
        WHERE

  s.nomissions>7 AND s.deactivation_date IS NOT NULL

  .. .and the code for the first date of deactivation for each year of activation agent

  select 
  a2.deactivation_date
  from
  agents a2
  where a2.deactivation_date= 
  (
  select min(a.deactivation_date)
  from 
  agents a
  where to_number(to_char(a.activation_date,'YYYY'))=to_number(to_char(a2.activation_date,'YYYY'))
  )

  ..... I am not real to marry these two statements together in the Update statement. I can't extract each date of deactivation produced in the first select statement and their match against the first date of deactivation in the year they have been activated for the second select statement.
  
  Any help greatly appreciated... :))

  I began to wonder how things would :)

  First of all why he chooses the date the earliest of all agents

  He recovers as soon as the subquery has not been correctly set in the SET clause. It seems you are trying to update a correlated, but we are still having a conceptual shift. I have added a few comments to your code above and below will explain.

  (1): when you do a correlated update it is useful to the table alias that you did right here.

  (2): this table statement is not necessary and is the reason why the FIRST deactivation date is selected. The alias that you use (3) refers to THIS table, not the one defined in the update statement. Remove the line indicated by (2) in the FROM clause and a correlated update will happen.

  and secondly why is it to update each row, when I thought that I'm just the lines where the agents are disabled and missions > 7? Pointers on where I'm wrong would be very appreciated. (SQL = stupid query language!) :)

  WHERE EXISTS
  (
  SELECT
  a.agent_id,
  count(m.mission_id)
  FROM
  agents a
  /* INNER JOIN AC ON AC.AGENT_ID = A.AGENT_ID */
  INNER JOIN
  missions_agents m
  ON
  a.agent_id=m.agent_id
  GROUP BY
  a.agent_id,
  a.deactivation_date
  HAVING
  count(m.mission_id)>7 AND a.deactivation_date IS NOT NULL
  )
  

  Once again this problem is similar to the question above that a correlation update doesn't work. Test existence of lines in an EXISTS subquery. Since your subquery is not related to the table that you are trying to update, it will be always return a line and, therefore, it returns true for EACH LINE in the AGENTS table. To limit the game to only agents > 7 missions results, you need to add a join condition that references the table in your update statement. I added one above (with comments) as a sample.

  I recommend you look over all material that you have associated with correlated subqueries, including documents that I posted above. This seems to be what you're having the problem more with. If you need me to explain the concept of correlated queries any better please let me know.

  Thank you!

• Use the CASE statement in a query of LOV

  Hello
  
  I wrote a select statement to be used in my list of values query, and it works fine when I run with SQL Developer. But when I put it in the LOV I get the LOV query is invalid error message. Here's the query I use:
  

  select 
      case when nt.COMMON_NAME is not null then nt.COMMON_NAME || ' (' || nt.TAXON_NAME || ')'
          else nt.TAXON_NAME
      end display_species
     ,case when nt.COMMON_NAME is not null then nt.COMMON_NAME || ' (' || nt.TAXON_NAME || ')'
          else nt.TAXON_NAME
      end return_species
  FROM NBN_TAXON nt
  WHERE lower(nt.INPUT_CATEGORY) = decode(lower(:P312_TAXON_GROUP_ADD), 'fish', 'fishes', lower(:P312_TAXON_GROUP_ADD))     
  order by 1;

  If the CASE statement is the source of the problem?

  Hello

  Try to remove the colon semi at the end.

  See you soon

• Help with making SQL query references to column aliases in the Case statement

  I need help with a sql query that I'm trying. I can go about it the wrong way, but I would be grateful if I could get any suggestions on possible solutions. This is my query:
  
  
  SELECT DISTINCT spriden_pidm, spriden_id id, spriden_last_name | ',' | spriden_first_name name,

  The second case statement is where I don't know exactly what it takes to get what I want.
  
  Output should be like:
  spriden_pidm name ID acg_elig_comm_code comm_code_description
  «0000000000', ' 1111111111 ","John Doe","268", «rigorous HS race"»
  
  If I take the second case statement it works great except that I do not have my comm_code description column. My question is how can I use my first statement value box to determine this column? I think that I need a case statement as I have, but I don't know how to reference the value of acg_elig_comm_code. Any help would be greatly appreciated. Thank you.

  Hello

  You cannot use the alias column in the query, even where it is set (except in the ORDER BY clause).
  You can set the alias in a subquery and then use it in a great query, like this:

  WITH  sub_q  AS
  (
      SELECT DISTINCT spriden_pidm,spriden_id id, spriden_last_name||', '||spriden_first_name name,
          CASE
              WHEN rcresar_comm_code_01 IN ('268','269','270') THEN rcresar_comm_code_01
              WHEN rcresar_comm_code_02 IN ('268','269','270') THEN rcresar_comm_code_02
              WHEN rcresar_comm_code_03 IN ('268','269','270') THEN rcresar_comm_code_03
              WHEN rcresar_comm_code_04 IN ('268','269','270') THEN rcresar_comm_code_04
              WHEN rcresar_comm_code_05 IN ('268','269','270') THEN rcresar_comm_code_05
              WHEN rcresar_comm_code_06 IN ('268','269','270') THEN rcresar_comm_code_06
              WHEN rcresar_comm_code_07 IN ('268','269','270') THEN rcresar_comm_code_07
              WHEN rcresar_comm_code_08 IN ('268','269','270') THEN rcresar_comm_code_08
              WHEN rcresar_comm_code_09 IN ('268','269','270') THEN rcresar_comm_code_09
              WHEN rcresar_comm_code_10 IN ('268','269','270') THEN rcresar_comm_code_10
          END acg_elig_comm_code   -- Originally posted with , here (error)
      FROM spriden, rcresar, rcrapp1
      WHERE (rcresar_comm_code_01 IN ('268','269','270')
              OR rcresar_comm_code_02 IN ('268','269','270')
              OR rcresar_comm_code_03 IN ('268','269','270')
              OR rcresar_comm_code_04 IN ('268','269','270')

              OR rcresar_comm_code_06 IN ('268','269','270')
              OR rcresar_comm_code_07 IN ('268','269','270')
              OR rcresar_comm_code_08 IN ('268','269','270')
              OR rcresar_comm_code_09 IN ('268','269','270')
              OR rcresar_comm_code_10 IN ('268','269','270'))
      AND rcresar_aidy_code = &aidy_code
      AND rcrapp1_aidy_code = rcresar_aidy_code

      AND rcrapp1_seq_no = rcresar_seq_no
      AND spriden_pidm = rcresar_pidm
      AND rcrapp1_pidm = rcresar_pidm
      AND spriden_change_ind IS NULL
  )
  SELECT    sub_q.*,
            CASE
                WHEN acg_elig_comm_code = '268' THEN 'Rigorous HS course'
                WHEN acg_elig_comm_code = '269' THEN '2 or more AP or IB'
                WHEN acg_elig_comm_code = '270' THEN 'ACG possible'
            END comm_code_description
  FROM      sub_q
  ORDER BY  name
  

  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.
