• Problem with the simple query.

  Hi all

  I am facing problem with the query below

  Select A.COL1, A.COL2

  B.COL1, B.COL2

  FROM TABLE1 A

  TABLE 1 B

  WHERE A.header = '123'

  AND B.header = '123'

  AND nvl (A.COL6, 'ABC') = 'ABC '.

  AND NVL (B.COL6, 'DEF') = 'DEF '.

  Basically, my requiremenyt is: I have only one table, TABLE1 here, which has a line two lines (for the same header) as "ABC" and another is "DEF". Table 1 has two columns (col1, col2) that should be displayed for both lines.

  When the header has two records in table1 top query works. and but if I do not have a record for any header example there are a record for "abc" in col6 only. so my query above does not work because there is no record for 'DEF' in col6. But I want to again request to fecth the output (for b.col1 and b.col2 should have null values)

  could you pls suggest me how to get the 4 columns.

  Thanks in advance

  Kind regards

  UVA.

  Try to place the status of outer join on column: analytical_criterion_code as

  and nvl (AUDIT.analytical_criterion_code, 'AUDIT2') = 'verification2. '

  .

  .

  and nvl (TRANS.analytical_criterion_code, 'TRANS2') = 'TRANS2.

  In the sub query based on the opinions that you have given in post # 1, although there is no value "DEF * ' for col6 due to the condition of outer join on b.col6 (+) line is extracted with b.col [1,2,3] as NULL values. Try to remove the (+) sign b.col6 and test.

  with t as)

  Select 111 col1, col2 'aaa', 'ABC' col6 123 header of all the double union

  Select 222 'bbb', 'DEF' col6, 123 double header

  )

  q as (select 123 double header)

  Select A.COL1, A.COL2, A.COL6

  B.COL1, B.COL2, b.COL6

  q.header

  T a

  t b

  q

  where a.col6 (+) = 'ABC '.

  and b.col6 (+) = "DEF."

  and q.header = a.header (+)

  and q.header = b.header (+)

• Better way to write the simple query?

  I'm trying to get the date of 'busy' max 'mansion '.
  
  It is an example, I imagined, since I can't post our actual data. The following query works, but is their path easier.
  

  CREATE TABLE TEST_TABLE (  
  LOAN_NUMBER                 VARCHAR2(15 Byte),
  UN_ID                       NUMBER,
  CHANGE_DATE                 DATE,
  PROP_TYPE                   VARCHAR2(25 Byte),
  OCCSTAT                     VARCHAR2(25 Byte)
  ); 
  COMMIT;
  
  
  INSERT INTO TEST_TABLE VALUES (123456,  1,'01-JAN-09','Tent','Occupied');
  INSERT INTO TEST_TABLE VALUES (123456,  2,'01-FEB-09','Shack','Occupied');
  INSERT INTO TEST_TABLE VALUES (123456,  3,'01-JUN-08','Single Family','Occupied');
  INSERT INTO TEST_TABLE VALUES (123456,  4,'01-OCT-08','Single Family Plus','Occupied');
  INSERT INTO TEST_TABLE VALUES (123456,  5,'01-DEC-08','Mansion','Occupied');
  INSERT INTO TEST_TABLE VALUES (123456,  6,'05-JAN-09','Mansion','Unoccupied');
  COMMIT;

  Reason, I take the ID's for the second join because I know that the ID max = max.
  

  select     
  i2.UN_ID,
  i2.CHANGE_DATE,
  i2.PROP_TYPE,
  i2.OCCSTAT
  from 
  (
      select 
          distinct(LOAN_NUMBER) AS "LOAN_ID", 
          max(UN_ID) AS "ID_MAX"
      from(
      select 
          LOAN_NUMBER,
          UN_ID
    from
          TEST_TABLE
      where OCCSTAT = 'Occupied'
      group by LOAN_NUMBER, UN_ID
      ) 
      group by LOAN_NUMBER
  )i
  left join TEST_TABLE i2 on i.ID_MAX = i2.UN_ID

  easier way without the second join?
  
  Thanks in advance.
  
  R

  Try this query, it should be equivalent to your:

  select UN_ID, CHANGE_DATE, PROP_TYPE, OCCSTAT
  from (
      select LOAN_NUMBER, UN_ID, CHANGE_DATE, PROP_TYPE, OCCSTAT, rank() over(partition by LOAN_NUMBER order by un_id desc) rn
      from test_table
       where OCCSTAT = 'Occupied'
  )
  where rn=1

  01/01/2011 | A | Money | 4. 8
  01/01/2011 | B | Gold | 1. 3
  
  I need to write a query to get the result below:
  
  Date1 | Plane1 | Sum_Duration | Sum_Charge | Sum_Gold_Duration | Sum_Gold_Charge | Sum_Silver_Duration | Sum_Silver_Charge
  01/01/2011 | A | 9. 10. 5. 2. 4. 8

  SELECT Date1,
  base1,
  Sum (Duration) Sum_Duration,
  Sum (load) Sum_Charge
  FROM TABLE_A
  GROUP BY date1, rarateplan
  
  But I need to know how to get the rest of the columns (i.e. Summary according to categories; from 5 to 8 columns)? Is this can be done in a single query without writing subqueries?
  
  Please let me know, (with code), the best way.
  
  Thank you-

  Use like this:

  SELECT Date1,
  base1,
  Sum (Duration) Sum_Duration,
  Sum (load) Sum_Charge,
  SUM (decode(Category,'Gold',duration,0)) Sum_Gold_Duration,
  SUM (decode(Category,'Gold',charge,0)) Sum_Gold_charge,

• The simple query help

  Hello! I have a simple request: NO of ROAD_TYPE = "RAMP" or NO FUNC_CODE = 7 FUNC_CODE or NOT = 0 or NOT FUNC_CODE = NULL, each element of the query by itself without problem, tracks, but linked together in this way with the GOLD, one of them opts on. What I am doing wrong?

  It's the difference between OR and and.

  Think about this simple example

  Where Column != A or Column != B.
  

  Excluding the Null handling, it's true. Because for the first condition, it will be true for all but one, and the second condition will be true for A. You need an AND, not a RC.

  For simplicity and readability without doubt, use an In operator, and group together them. It would therefore be:

  Where Road_Type != 'RAMP' and Func_Code Not In('0, 7) and Func_Code is not Null

  Hello

  The answer to "" How do I... using DECODE? ". is always "do not DECODE." If you have to ask, then it's too complicated.
  CASE is the most common to DECODE alternative.

  If you want to use the results in a WHERE clause, why not use the conditions in a WHERE clause, without DECODING?
  Something like that, maybe:
  {code}
  WHERE is_auth = 'TRUE '.
  THERE ARE (SELECT 1 OR)
  OF cust_order_tab
  Situation WHERE = 'product '.
  AND order_no = customer_issue_tab.order_no
  )
  {code}

• Functions in the inner query

  Hello!
  I challenged the following problem. Here's the simple query:
  
  SELECT id, id, id from
  (select 1, sys_guid () as double id)
  
  as you can see there is a sys_guid() function in the inner query. So, why do we use these
  constructions? Right - to calculate the value of a function once and use it again so much
  time, that we need. So I guess to get three identical fields. But, as it turns out, it is not
  always too! I mean, on one version of Oracle database this query return the same three
  fields, but on another - three different! Based on what the sys_guid() function is a kind of
  random function, I can assume that the function is run three times in the second case
  instead of one (as it should)! So why is it? Is - this bug from version, or an option in
  control file that influence the optimizer?
  
  PS: I found a workaround on this basis, where this query produces abnormal results, we can use
  Internal ORDER BY clause in the query:
  
  SELECT id, id, id from
  (select 1, sys_guid () as command id double by 1)

  The oracle optimizer is the fusion view inline with the outer select block. He replaced effectively by:

  select sys_guid(), sys_guid(), sys_guid()
  from dual
  

  You can avoid this as follows:

  select /*+ no_merge(x) */
           id,id,id from
  (select 1,sys_guid() as id from dual) x

  Hi friends,

  I have a Simple search query region in 11i.

  I created the SearchVO and bound to the query Table Region.

  I have two attributes MessageStyleText and a MessageChoice attribute in the simple search criteria.

  Search results show very well for all attributes.

  But when I search with the criteria of MessageChoice, in the table of results, this attribute MessageChoice is indicated as editable, display the drop-down list.

  I did this attribute ReadOnly = True but then it becomes readonly in search also. So this dosent help.

  I need to this drop-down list of MessageChoice be modifiable in the search criteria, but read in the table of results.

  Please help me with the resolution. Its kinda urgent.

  Would appreciate any help.

  A full table scan might be the fastest way to get results. Do you have any reason to think that it would be faster to go through the index? How selective are the clues? In other words, what is the percentage of rows in the table correspond to each of the values in the WHERE clause?

  2. is the right to approach?

  It depends on what you're trying to do, which is not at all clear to me.

  Would the use of the concat operator in the function decode work better for my needs?
  Something like

  Select decode (APP |) STEP, 'SAPP9332', 'X') of TRANSACTION_HISTORY where

  If you use this approach, look out for the problem Ab asse crevit . For example, if you have these 4 rows and 2 columns:

  str1     str2
  ----     ----
  (NULL)     FOO
  F     OO
  FO     O
  FOO     (NULL)
  

  There are 4 values of distict of str1 (counting NULL) and 4 separate values of str2, str1 but | str2 is the same for each of them. In the above example, it there is no way to know, just by looking at the concatenated string, including str1 and str2 ends begins. Maybe it's not the case for your specific data (for example, if the application is still exactly 5 characters long). otherwise, you may need to add some kind of delimiter, like this

  app || '+' || step
  

  where you know that '+' never occurs in one of these columns.

  3. ANY other approach / request for my requirement.

  CASES, as I mentioned in your previous message:
  Decode the help function
  and as you have used above.

  In this thread, you said "I have to use the decode function. Why? It is a competition of school Etudieeo DECODE is explicitly required? Why you don't want in the best way, what that turns out to be?

  Your WHERE clause:

  AND APP IN ('SAPPI', 'SAPPI', 'SAPR3')
  AND STEP IN ('9320', '9332', '1208')
  

  admits 6 possible combinations of APA and step:

  app     step
  -----     ----
  SAPP1     9320
  SAPP1     9332
  SAPP1     1208
  SAPP3     9320
  SAPP3     9332
  SAPP3     1208
  

  but you are looking for only 3 of these combinations in DECODE it or the expression BOX. (Have 2 copies of 'SAPP1' e list won't do any good, but it does hurt real, either.)
  By the way, is "SAPPI" app with the letter 'I' at the end, or "SAPP1", with the number '1' at the end?

  DBA_TS_QUOTAS does not have the space, but rather the maximum allowed for a given user.

  What happens if your user John has Quotas on 3 tablespace TBS1 and TBS3 and TBS2?
  You can't expect the outer query to retrieve only the more than 27 just line because the inner query returns 27 rows.

  For the space allocated by the storage space for newly created users, you'd better ask dba_segments. something like:

  select owner, tablespace_name, trunc(sum(bytes)/1024/1024) alloc_mb
  from dba_segments
  where owner in (select username from dba_users where created > sysdate - 4)
  group by owner, tablespace_name

• How to exclude records from the outer query

  My apologies if this was requested. I find no answer. I don't know what terminology should be for that matter.

  In simple terms, I want to use the custom in where clause to select records. Problem is function will fail if applied to old records, as there was no relevant data. I have logic to exclude old records, but the problem is that this process running function before old records are excluded. I tried an inside view to exclude records before their passage in the outer query, but this does not resolve the situation.

  Below shows high level required

  Select x

  tab

  where (condition to exclude the old records)

  and function (tab.y) = value

  If I rewrite as below, still have the problem. Was hoping to exclude former records apply before function.

  Select inn.x

  Of

  (select x,

  There

  tab

  where (condition to exclude the old records)) inn

  where function (inn.y) = value

  Thank you

  Hello

  Including ROWNUM in the result set of the query-void will force the subquery to do first:

  Select inn.x

  Of

  (select x,

  There,

  ROWNUM AS r

  tab

  where (condition to exclude the old records)

  ) inn

  where the function (inn.y) = some_value

  Since ROWNUM depends on the WHERE clause of the query-sup, the query cannot be rewritten to the main to do first query WHERE clause.
