• Select Max (date) multiple records

  I'm having a problem getting the last value for several gauges.  Here's my query:

  SELECT parameter_id,

  TS_ID,

  value,

  Location_id,

  Date_Time

  Of

  MyTable

  JOIN IN-HOUSE

  mytable2

  WE

  TS_ID = ts_id

  WHERE

  TS_ID LIKE '% - rev.

  unit_id = ("pi")

  the value IS NOT NULL

  Location_id as "xxxx".

  Date_Time =

  (SELECT Max (date_time)

  My TABLE

  GROUP BY parameter_id)

  ;
  

  Hello

  A scalar subquery, such as the expression to the right of the sign =

  Date_Time = (SELECT...)

  must produce (at most) only 1 row.  If the subquery produces 2 or more lines, it will trigger an error.

  Given that you are using "GROUP BY parameter_id" in the subquery, it will produce a separate line of output for each distinct value of parameter_id.  You can use a correlated subquery at that time, that only looks like a parameter_id, or you can use a subquery IN, like this:

  WHERE (parameter_id, Date_Time) IN

  (

  SELECT parameter_id

  MAX (date_time)

  FROM MyTable

  GROUP BY parameter_id

  )

  I hope that answers your question.
  If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) and also publish outcomes from these data.
  Explain, using specific examples, how you get these results from these data.
  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

  FROM (
    SELECT id, sampleid, compoundname, requisition, substr(requisition,2,4) sub_req,
           row_number() over(order by substr(requisition,2,4) desc) rn

• Text ToolTip APEX of select list query

  Hi all

  Currently, I'm stuck with how to display the ToolTip text by using a selection list query. I tried to look for the solution but I got is: assigning help unique text value. I also passed by the example:

  https://Apex.Oracle.com/pls/Apex/f?p=44321:410:

  When I'm hovering above the value of column Loc Departments IR, , it displays the ToolTip text in a list. My requirement is almost the same. I will implement for the page element and the value of the list will be generate by query.

  
  

  I use 5 APEX with Database 11g
  

  
  

  Any help would be appreciated.

  
  

  
  

  Concerning

  Nabila

  I solved this problem. I just want to share this, if anyone needs.

  1 created dynamic action on loading of the page.

  2. Choose the action ToolTip [plug-ins].

  3. ToolTip content type: Code PL/SQL which is:

  Start

  Select: P260_FINANCIALINSTRUMENT

  in l_help_text

  Double;

  HTP.p (replace (nvl (l_help_text, "no help is found.'"), ', ' '))
  '));

  exception

  while others then

  HTP.p ('no help is found.');

  end;

  4. affected elements--> JQuery selector:

  Label [for = P78_FINANCIALINSTRUMENT] Caddy-tip

  Note:

  I used the Tooltip Plugin which is mentioned in my original post.

  78 is my page number created if the dynamics of the action when the page is loaded. And P78_FINANCIALINSTRUMENT matches the element for which the ToolTip will come as a selection list.

  P260_FINANCIALINSTRUMENT is the element that contains the actual value of the selection list. I used the database query to get the value separated by,

  Start

  Select listagg (Orders, ',')

  THE Group (Control Orders) Orders

  in: P260_FINANCIALINSTRUMENT

  of Orders;

  end;

• Select Max (Date) in two different tables...

  Dear all,

  I need the date of last update of two different tables, I mean max (date). We will update one table at a time. Updated once I need to take the last update.

  It can be either in table A table B.

  for example.

  Table A

  Date of the ID

  100 16/05/2014

  101 20/05/2014

  102, 22/05/2014

  Table B

  Date of the ID

  100 04/06/2014

  101, 26/05/2014

  102 21/05/2014

  I need the date of table B (101 26/05/2014) last updated date...

  Hello

  Another way, using much more GRAND:

  SELECT LARGER (max1, max2) x

  FROM (SELECT MAX (mydate) max1

  OF mytable_a

  )

  (SELECT MAX (myotherdate) max2

  OF mytable_b

  )

  ;

  Best regards

• Select Max (date) between multiple tables

  I need to retrieve a record from a Table in a set of similar tables with a common "date field". You can select the record where this "date field" value is greater between multiple tables.

  Here, any help is appreciated.  Thank you in advance.

  FOR EXAMPLE

  No. EMP is the primary key.

  Again, each table can have multiple records for EMP n ° 1

  TABLE1:

  FIRST NAME

  FAMILY NAME
  THE EMP NO.

  BASE SALARY

  DATE_FROM

  TABLE 2

  FIRST NAME

  FAMILY NAME
  THE EMP NO.

  SALARY GRADE

  DATE_FROM

  TABLE 3

  FIRST NAME

  FAMILY NAME
  THE EMP NO.

  COMPENSATION

  DATE_FROM

  Hello

  Said Knani, if you use the current design of the table, then here is a way to do what you want:

  WITH union_data AS

  (

  SELECT MAX (base_salary) AS sal FROM table1 UNION ALL

  SELECT MAX (grade_salary) table2 UNION ALL

  SELECT MAX (compensation) FROM table3

  )

  SELECT MAX (sal) AS max_sal

  Of union_data

• Select the query with the level line list where the clause

  Hi all
  
  I am creating a tabular presentation based on a SQL query that has a list of selection based on a query with a where clause clause that refers to a column in the original SQL query.
  
  The situation is, I have a table that stores the client_id, source_id, and build_id, lets call it client_source. I have a second table, build_source, containing source_id and build_id, one to many relations between the two (1 source_id could have build_id 1-7).
  
  Using a tabular presentation, I want to select the correspondent build_id to use in client_source, but the selection list should contain only the build_id for this particular source_id of lines.
  
  Here is an example of the SQL source of tabular presentation;
  
  Select
  s.ROWID,
  s.CLIENT_ID,
  s.SOURCE_ID,
  APEX_ITEM. SELECT_LIST_FROM_QUERY (1, s.BUILD_ID,)
  "Select display b.build_id, b.build_id return.
  b build_source where b.source_id = s.SOURCE_ID ') lst
  of s client_source
  
  what I want to achieve, it's as source_id "BOLD" match fields. When the query is built this way, I get an error of "invalid identifier" Oracle on s.SOURCE_ID during execution.
  
  Is there some special tags to be used to refer to the external column? I must be missing something because this looks like a pretty mundane problem.
  
  I am running on 4.1.0.00.32, on an Oracle 10 g release 10.2.0.4.0 Server Express request.
  
  
  I look forward to useful responses!
  
  
  See you soon,.
  Jason
  
  Published by: 1005131 on May 9, 2013 19:02

  Your selection by query list receives a static SQL. That SQL can't "see" the value of your s.source_id.
  But it would work like this:
  where b.source_id = ' | s.SOURCE_ID)

  You would be the value for the SQL concatenation. It is not ideal, but it will work.

  Basically, I need to run and update the declaration (not plsql) to update the Spell_tags table service_line_spell field with the service_line of the ranked_spells table (lowest rank)
  
  Here are a few failed attempts, do not laugh ;)
  

  update spell_tags
  set service_line_spell = (select max(service_line) from ranked_spells
  where spell_tags.spell_id = ranked_spells.spell_ID
  group by service_line, rank
  having rank = min(rank))
  where spell_ID in (select distinct spell_ID from ranked_spells);
  
  ERROR at line 2:
  ORA-01427: single-row subquery returns more than one row
  
  
  update speccom.spell_tags
  set service_line_spell = (select b.service_line from ranked_spell b
  where spell_tags.spell_id = ranked_spells.spell_ID
  and ranked_spells.rank = min(ranked_spells.rank) group by service_line, rank)
  where exists
  (select spell_ID from ranked_spells
  where spell_ID in (select distinct spell_ID from ranked_spells);
  
  ERROR at line 4:
  ORA-00934: group function is not allowed here

  This is the result, I need: -.
  

   Select * from spell_tags;
  
  SPELL_ID                                           SERVICE_LINE_SPELL
  -------------------------------------------------- -------------------------
  100002                                             SD08s
  100003                                               SD23x

  Any ideas guys?

  Something like that?

  update spell_tags
  set service_line_spell = (select max(service_line) keep (dense_rank last order by rank desc)
                            from ranked_spells
                            where spell_tags.spell_id = ranked_spells.spell_ID
                            )
  where spell_ID in (select distinct spell_ID from ranked_spells);

• SELECT MAX (FILE_VERSION)

  I put the following portion of the code in a WHERE clause:
  

             AND PCMS_CHDOC_ACTION_DESC_2.FILE_VERSION IN 
  
                    (SELECT MAX(FILE_VERSION) 
  
                       FROM PCMS_CHDOC_ACTION_DESC PCMS_CHDOC_ACTION_DESC_4
  
                     WHERE PCMS_CHDOC_ACTION_DESC_4.CH_UID = PCMS_CHDOC_DATA_2.CH_UID                                                                              AND PCMS_CHDOC_ACTION_DESC_4.CH_DOC_ID = PCMS_CHDOC_DATA_2.CH_DOC_ID)

  .. .but for records where the FILE_VERSION is null or doesn't retrieve any record.
  
  There is a way to write such can also retrieve records that are null?

  AND (PCMS_CHDOC_ACTION_DESC_2.FILE_VERSION IN
                    (SELECT MAX(FILE_VERSION)
                       FROM PCMS_CHDOC_ACTION_DESC PCMS_CHDOC_ACTION_DESC_4
                    WHERE PCMS_CHDOC_ACTION_DESC_4.CH_UID = PCMS_CHDOC_DATA_2.CH_UID
                                  AND PCMS_CHDOC_ACTION_DESC_4.CH_DOC_ID = PCMS_CHDOC_DATA_2.CH_DOC_ID
                                ) OR PCMS_CHDOC_ACTION_DESC_2.FILE_VERSION IS NULL)
  

  or doesn't exist doesn't retrieve any record.
  

  What do you mean by that?

• Subquery scalar to select max

  Hi all
  
  Oracle Version
  11.2.0.1.0
  
  
  I need to write a query update one table based on the following criteria:
  

  create table trades (tid number, descp varchar2(20));
  
  create table trade_descp (tid number, aud_desc varchar2(20), c_date date)
  
  
  insert into trades
  values
  (1,NULL)
  
  insert into trades
  values
  (3,NULL)
  
  insert into trades
  values
  (4,NULL)
  
  insert into trade_descp values
  (1,'abdc(M)','1-Jan-2012')
  
  insert into trade_descp values
  (1,'abdc(M)','1-Jan-2013')
  
  insert into trade_descp values
  (1,'abdc(N)','1-Jan-2014')

  The output I need is to update the table of trades with a description with the maximum date of trade_descp table based on a filter for example descp like "%M %.
  There is an index on the column tid trade_descp table (with huge files).
  
  Can this be achieved in direct SQL.
  
  
  Thank you and best regards,
  Nik

  but that is a full table of trade_descp table scan. Can we make us of the index built on the TID column?
