SQL query returns no row vs. multiple lines

Similar Questions

• SQL query returning no rows, please help!

  I have a table that contains the user checks for a specific procedures alongwith the date stamp. Now, I want the list of all procedures that are not accessible by users in the last 6 months. Or, all of the procedures that have not been used/accessible during the last 6 months.
  
  That's what I'm trying, but is does not return all rows:
  
  SELECT DISTINCT proc_name,
  TRUNC (entry_date)
  OF log_web
  WHERE NOT IN (SELECT proc_name proc_name
  OF log_web
  WHERE TRUNC (entry_date) > TRUNC (SYSDATE - 180))
  ORDER BY DESC 2
  
  Please notify.
  Thank you in advance.

  Hello

  NOT IN never returns TRUE if the subquery returns NULL values. If proc_name doesn't have a NOT NULL constraint, change the subquery to

  WHERE        proc_name     NOT IN ( SELECT  proc_name
                              FROM      log_web
                       WHERE      entry_date     > TRUNC (SYSDATE - 180)
                       AND      proc_name     IS NOT NULL
                        )
  

  I don't see any other suspect.

• If a view object query returns no rows, can the vacuum to be tested at all?

  All those who know or have also experienced:
  
  I guess that the answer should be Yes, but I tried anyway, I still didn't worked. Here is the code (it's a method behind a command button, a bean of support (I use JDeveloper 10.1.3.4).) In the code, LoggedInStudent is the name of a view object; ZBLCModule is the name of the application module):
  

      public String commandButton1_action() {
          FacesContext fc = FacesContext.getCurrentInstance();
          ValueBinding vb = fc.getApplication().createValueBinding("#{data}");
          BindingContext bc = (BindingContext)vb.getValue(fc);
          DCDataControl dc = bc.findDataControl("ZBLCModuleDataControl");
          ApplicationModule am = (ApplicationModule)dc.getDataProvider();
          ZBLCModuleImpl zblcam = (ZBLCModuleImpl)am;
          LoggedInStudentImpl studentsFound = (LoggedInStudentImpl)zblcam.getLoggedInStudent();
          
          String navCase = null;
          
          // Test (1): if the view cache is empty; always bombs up the application if it IS empty:
          if(studentsFound.getAllRowsInRange().length == 0) {
              navCase = "userNotFound";
          // (2) The following three tests gets to run only when the cache is not empty; they work fine.
          } else if (((Number)studentsFound.first().getAttribute("HoursAttm")).floatValue() == 0.0) {
              navCase = "noHours";
          } else if (((Number)studentsFound.first().getAttribute("Balance")).floatValue() > 0.0) {
              navCase = "notZero";
          } else if (!(studentsFound.first().getAttribute("Validated").equals(" "))) {
              navCase = "validated";
          } else {
              navCase = "zeroBal";
          }
          return navCase;
      }

  When the view object query returns a line, the whole of the application works without error. When the query returns no rows, test (1) always bombs toward the top of the application, prompting a Houston-30003 error.
  
  (1) test, I tried the following:
  

    if (studentsFound.getAllRowsInRange().length == 0)
    if (studentsFound.first() == null)
    if (studentsFound.getEstimatedRowCount() == 0)
    if (studentsFound.isDead()) //I do not know what isDead() does; just tried desperately.
    if (studentsFound.equals(null))
    if (studentsFound.getCurrentRow() == null)

  With each of these events, I got an error of Houston-30003. It does not matter what looks like the conditional test; It is important only when the objects from view cache is empty. If the view cache is not empty, everything, including the test (1), works very well. And when the cache is empty is not because of the failure of the connection to the database, but because the student is not in the data table and line are for the student.
  
  It is a requirement of the company to do something when the view object query returns no rows. Can it be tested at all? How?
  
  Or is there something wrong in the first lines in the method before the {color: green} String navCase = null; {color} line?
  
  Thank you very much for your help!

  Hello

  What you have done, is to get a handle to the object that CAN execute queries to the database.
  However, you do not query the database.

  Just add:

    LoggedInStudentImpl studentsFound = (LoggedInStudentImpl)zblcam.getLoggedInStudent();
    //New line
    studentsFound.executeQuery();
  

  The code that Shay has given you is when you do not have a request for all module, but since you are talking about a command etc button I guess that the module of the application is already active.
  The line I gave you should be enough to make it work.

  I'd be careful with the

  studentsFound.hasNext();
  

  I suggest to use estimatedRowCount();

• Oracle Text multi column index based query returns no rows

  Hello
  
  I have a MAH_KERESES_MV table with 3 columns OBJEKTUM_NEV, KERESES_SZOVEG_1, KERESES_SZOVEG_2. I create the following Oracle multi column text index:
  
  ctx_ddl.create_preference exec ('MAH_SEARCH', 'MULTI_COLUMN_DATASTORE');
  ctx_ddl.set_attribute exec ('MAH_SEARCH', 'COLUMNS', 'OBJEKTUM_NEV, KERESES_SZOVEG_1, KERESES_SZOVEG_2');
  
  create index MAX_KERES_CTX on MAH_KERESES_MV (OBJEKTUM_NEV)
  indexType is ctxsys.context
  parameters ("DATASTORE MAH_SEARCH");
  But the query returns no rows, although if I make the query with the 'like' operator, and then I get the results as expected:
  
  SELECT id, OBJEKTUM_NEV
  OF MAH_KERESES_MV
  WHERE CONTAINS (OBJEKTUM_NEV, "C") > 0;
  
  Can some body please help? TIA,
  
  Tamas

  You can do it in Oracle Text, well it is not necessarily desirable.

  You can search the

  WHERE CONTAINS(OBJEKTUM_NEV, '%C%')>0;
  

  And it will probably work in a simple test. However, using a leader like this wildcard prevents them the index on the table "list of words" used, so such a request can be very slow on a large system.
  You can improve this by using SUBSTRING_INDEX, but making your much bigger index. And you could always hit the 'expansions too' problem if %C % expansion is more than about 15,000 words (depending on version and different settings).

  Also be aware of differences in case - %C % will match 'fact' or 'FACT', as part of a CONTAINS, but not part of a TYPE.

• Stupid old backpacker (me) cannot understand why this query returns 1 row

  Hi all
  
  In reference to {: identifier of the thread = 2456973}, why do
  

  select sum(count(decode(job, 'CLERK', 1, null))) CLERKS
  , sum(count(decode(job, 'SALESMAN', 1, null))) SALESMANS
  from emp group by job;

  only 1 rank and not 1 for each task? In fact, I had to test it myself to believe.
  
  It returns the data as if the query were
  

  select sum(CLERKS), sum(SALESMANS)
  from (select count(decode(job, 'CLERK', 1, null)) CLERKS, count(decode(job, 'SALESMAN', 1, null)) SALESMANS
           from emp group by job)

  Using only a single aggregate (count or sum) returns 1 row per job, as expected

  Exactly the point ;-)

  It seems that Oracle actually do, a group of 'double' in the same operation.
  Attend plans to explain in this example:

  There are GROUP BY hash and SORT GLOBAL times.

  It is really unnecessary to an aggregate on an aggregate - if two aggregates are used "in the same group level.
  Sum() aggregates are used on an already aggregated value, so it doesn't look like Oracle which actually cures like 'first do the internal aggregate using the group specified by and then do the external aggregation on the result with any group.'

  Look at this example where I combine aggregates "double" with "single" aggregates:

  SQL> select sum(count(decode(job, 'CLERK', 1, null))) CLERKS
    2       , sum(count(decode(job, 'SALESMAN', 1, null))) SALESMANS
    3       , count(decode(job, 'SALESMAN', 1, null)) SALESMANS2

  When you mix "doubles" and "single" aggregates, Oracle decides that unique aggregates belong to the 'outer' aggregation
  SALESMAN2 did a count on the aggregated work column which is the result of the 'internal' group by - so only 1.
  The count (*) is also the result of the aggregation of the 'internal '.

  I don't know if it's documented or if it is an 'effect' of internal code used for GROUPING SETS or the internal code used to enable the analytical functions like this:

  SQL> select count(decode(job, 'CLERK', 1, null)) CLERKS
    2       , count(decode(job, 'SALESMAN', 1, null)) SALESMANS
    3       , sum(count(decode(job, 'CLERK', 1, null))) over () CLERKS2

  Personally, I think that I would have preferred if Oracle has raised an error on this "double aggregation" and therefore require me to write this way (if it's the result I wanted):

  select sum(CLERKS), sum(SALESMANS)
  from (select count(decode(job, 'CLERK', 1, null)) CLERKS, count(decode(job, 'SALESMAN', 1, null)) SALESMANS
           from emp group by job)
  

  I don't really see a good use case for aggregations of 'double'-, but rather that he could give you undetected bugs in your code, if you happen to do double aggregation without noticing.

  Interesting thing to know ;-)

• SQL query - only unique rows back

  Hello
  
  If you have an employee table, where employees are listed by Department, using SQL, could return you the names of the employees listed by Department on one single line?

  Jack 20
  10 Joe
  Jill 20
  Jacinta 10
  30 John
  Jeffrey 30

• reload the page when SQL query returns a value

  Hello world

  the title of this discussion may seem strange, but I'll try to explain why I need this:

  A user has the ability to connect on my APEX application. There are several tabs in my application that are visible only if a certain SQL statement returns a value which is not the case by default. The user has also the ability to download a file that is transferred to an external system that analyzes the file and writes the data in the database. During this writing process - which may take several minutes - conditions for some of the tabs to show the will becomes real (-> the query will return a value). When the user refreshes the page manually, the tabs will be displayed. However, I want the tabs will appear automatically when the condition is met.

  Is it possible to refresh the page as soon as the query returns a value? It is perhaps possible to check it on the client side and trigger a refresh of the page when the condition is met. It would be even better if only the tabset has been updated, but refreshing the full page is fine as well.

  Thank you!

  Here is an overview of how it can be done

  This is possible thanks to a dynamic action being performed on a timer.

  View default tabs and dynamic action hide them on loading the page if they are not to be considered

  Create a dynamic action that will execute your query every 5 seconds or more

  If the query returns data, you can use the dynamic action to show your tabs using javascript

• Attributes XML makes my query returns no rows

  Hi all
  
  I have a strange problem.
  
  I ask an XML, but the attributes in one of the tags my query will return no rows. If I delete the attributes, the query works as expected.
  
  The XML code is below; This is the Report tag attributes that cause problems:
  

  <result errorCode="0">
       <return>
            <Report

  </result>

  My query is:

  I tried to strip the attributes to the tag, which works, but some XML I look back are large enough (number of records), so that cause problems in itself. I would rather deal with it and don't mess with the XML itself if possible.
  
  Any help would be much appreciated!
  
  Thank you much in advance.

• 'Function SQL Query return' using with Flash graphics

  I created a pl/sql function that returns a SQL query in a varchar2 of this form:
  
  Select the null link
  -value > < x value
  < value y of Series1 > series 1 label
  < value Series2 y > 2 series label
  < value of y Series3 > series 3 Label
  ...
  ...
  from tablea a
  Join tableb b
  On a.col = b.col
  order of < x value >
  
  If I call the function of a graphic Flash box series SQL with the Type of Source query "SQL query" value that returns the function like this:
  
  return functionname (to_date ('30-sep-2010, ' mon-dd-yyyy ""))
  
  It parses correctly and the page is saved; However, when I run the page I get no output - error messages or another indication of a problem.
  
  Now, if I call the function in a SQL client, capture the result of the query SQL using the dbms_output and paste that into the box graphic Flash series SQL - change the Source Type of SQL query query - and save the page it works fine when I run it and returns a chart series flash.
  
  Can anyone suggest either;
  
  1. what I might have missed or done wrong?
  2. a way to effectively diagnose the problem...
  
  I tried to use the debugger Apex - what is very nice, indeed - but it provides no information on what might be my problem. I tried to write my own my function debug messages using the apex_debug_message package - nothing...
  
  Thank you

  Hi Eric,.

  Try to pull the source like this:

  begin
     return functionname(to_date('30-sep-2010', 'dd-mon-yyyy'));
  end;
  

  This works very well for me, and if I take the begin-end and the final semicolon from the return statement I get the same behavior as you.

  He doesn't mention in aid of the source (only during the wizard if) this source type must be expressed in this way, but I agree, it would be useful that the tool would validate to this format meets it "Query SQL that returns the function" or give some sort of indication of the sentence. In any case, this should help you will again.

  Hope this helps,
  John

• PL/SQL Query return function, adding the column links

  Hi all
  
  I'm working on a SQL report with the area type = function from PL/SQL Query to return
  All columns are generated dynamically based on my mapping table and a column of ID.
  So whenever the page is loaded, according to the ID mapping table returns a set of columns in a particular order.
  So not only the columns are dynamic, but the order of the columns varies also.
  But the first 1 column is standard (it doesn't come from the mapping table) and is coded in my pl/sql block hard.
  
  I'm fighting with the addition of a link to this column. The link must be a Javascript function which takes the parameters in the form of 2 columns in the mapping table.
  My pl/sql block is something like that...

  v_select := 'SELECT <g href=javascript:f_report1(#map_id#,#comments#)><img src=""></a> as report1, ';  // g=a
  v_cols := 'contains all columns from the mapping table based on a ID(hidden item)';
  v_from := 'FROM table';
  v_where := 'where condition is put in here';
  v_query := v_select||v_from||v_where;
  return v_query;

  Now, I'm not able to transmit the values of this #map_id # and #comments # correctly. I tried so many different combinations of channels, but could not make it work.
  
  I'm not sure that the order of this map_id and commentscolumn and therefore cannot connect through the report attributes.
  How can I go to a column value to the function?
  
  
  
  Thank you
  Dippy

  This should work if all goes well:

  v_select := q'[ SELECT '' as chart, ]';

• User_Scheduler_Jobs query returns no row in the version 2.1.0.63

  Using the 2.1.0.63 version, "select * from user_scheduler_jobs;" returns no rows. It works fine in version 1.5.5.

  Refer to this topic, when the cause seems to be due to SQL Developer manages not null interval data types.

  bug? F9 gives no output dba_scheduler_jobs, version: 2.1.0.63.73

  As mentioned in this thread, you can use to_char on the columns of the interval as a workaround...

• SQL query return different result 11 GR 1 material and GR 11, 2

  Problem: SQL returns different results in 11 GR 1 material and GR 11, 2 games.

  Example script:

  create the table tab_main
  (
  SOS number (2) not null,
  contract number (2) null
  )
  /

  create the table tab_sub
  (
  number (2) of contract non-null,.
  SOS number (2) null
  )
  /

  insert into tab_main values (1, 10);
  insert into tab_main values (2, 20);
  insert into tab_main values (3, null);
  insert into tab_main values (4, null);

  insert into tab_sub values (1, 10);
  insert into tab_sub (20, 2) values;
  commit;

  The SQL code:

  SELECT *.
  OF tab_main.
  tab_sub
  WHERE tab_main.sos = tab_sub.sos (+) AND
  tab_main. Contract = tab_sub.contract (+) and
  tab_main. Contract not in (select 1 of the double);

  The above query gives more results
  -by 11.2.0.4
  1 10 10 1
  2 20 20 2
  

  -in 11.1.0.7
  1 10 10 1
  2 20 20 2
  4
  3

  
  Please tell us what could be the reason for the behaviour of offset lines thie.

  
  Thank you

  I think it is probably a bug in 11.1.0.7 (and possibly other versions), I get the same results as your 11.2.0.4 9.2.0.7, 10.2.0.3 and 11.2.0.3, and this is the result, I expect.

  Your not in the paragraph is equivalent to:

  SELECT *.

  OF tab_main, tab_sub

  WHERE tab_main.sos = tab_sub.sos (+) AND

  tab_main. Contract = tab_sub.contract (+) and

  tab_main. Contract <> 1;

  Since you have null values in tab_main.contract they are lost by the predicate since null = value is never true (or false).

• Large type query returning no rows

  Hello
  
  Posted in right forum hope eth, I also posted this in SQl & PL/SQL which is not the right forum, I think.
  
  I'm running a kind of large select query, counties of table is as shown below.
  
  The lines are not returned which is quite impossible.
  
  What could be the reason. Tablespace TEMP has run out or optimizer does not?
  
  My Oracle version: 10 G R/2
  I tried to update the statistics for each table, I am unable to check the TEMP tblspace as am not the ADMINISTRATOR.

  Anyy help is appreciated

  Seems to me that if the pid is different.
  Select * from where a pid = "ACT714";<-- no="">
  Select * from b where pid = "ACT714";<-- trailing="">

  Try
  Select count (*) of a, b
  where trim (a.pid) = trim (b.pid);

  If it works, you might want to consider how you store data, if they are supposed to be equal.

  Check also if you compare with the data type varchar2, char data type.
  I generally avoid the reasons char data type.

• Export query returns no rows

  Dear guy,

  I jam with this problem for 2 days and have you guy help me to check it out. Here's my parfile

  TABLES IS UMARKETADM. TRANS_DATA

  CONTENT = DATA_ONLY

  EXCLUDE = STATISTICS

  QUERY = UMARKETADM. TRANS_DATA: "WHERE transid in (select id from umarketadm.trans t where t.last_modified > to_date (5 January 2014 00:00:00 ',' DD/MM/YYYY hh24:mi:ss') and t.state in (2.6))" "

  DUMPFILE = SHARED_DIR:Demand.dmp

  Network_link = remote_db

  and the result is:

  . . exported "UMARKETADM." "" TRANS_DATA ".

  6,398 KB

  0 rows

  Main table 'SYSTEM '. "" SYS_EXPORT_TABLE_01 "properly load/unloaded

  But when I check in, select the table:

  Select count (*) in umarketadm.trans_data

  where transid in (select id from umarketadm.trans t where t.last_modified > to_date (5 January 2014 00:00:00 ',' dd/mm/yyyy hh24:mi:ss') and t.state in (2.6));

  
  

  then it results in: 1271258 lines

  Yes, is there some things wrong with my parfile?

  So thank you and best regards

  Hello

  I think that maybe it's a quirk of how works on network lnk datapump. I think the memory some of the rferences becomes 'local' rather than distance.

  You can try?

  TABLES IS UMARKETADM. TRANS_DATA

  CONTENT = DATA_ONLY

  EXCLUDE = STATISTICS

  QUERY = UMARKETADM. TRANS_DATA: "WHERE transid in (select id from umarketadm.trans@remote_db t where t.last_modified > to_date (5 January 2014 00:00:00 ',' DD/MM/YYYY hh24:mi:ss') and t.state in (2.6))" "

  DUMPFILE = SHARED_DIR:Demand.dmp

  Network_link = remote_db

  See you soon,.
