TO_date problem

• Unique / separate to_date problem

  Hey guys,.
  
  I am doing a project on feedback forms.
  There is a query that is bothering me in oracle...
  
  I used this application in the generation of reports in VB .NET.
  
  This is the query:
  
  SELECT unique (to_date(a.fdate,'dd-mon-yy')), t.teacher_name, s.subject_name, q.question_id, q.question_desc, q.opt1, q.opt2, q.opt3, q.opt4, count (a.opt1), count (a.opt2), count (a.opt3), (a.opt4) count of feedback f, answers, teacher t, s of subjects, questions q where A.FEEDBACK_ID = 'FF1' AND fdate as 5 January 09 ' and the group a.question_id = q.question_id and t.teacher_id = f.teacher_id and f.feedback_id = a.feedback_id and f.subject_id = s.subject_id by a.fdate t.teacher_name, s.subject_name, q.question_id, q.question_desc, q.opt1, q.opt2, q.opt3, q.opt4 order of q.question_id
  
  But this query gives ambiguous data as output.
  
  When I delete the attribute a.fdate to the query, it works fine.
  
  Select t.teacher_name, s.subject_name, q.question_id, q.question_desc, q.opt1, q.opt2, q.opt3, q.opt4, count (a.opt1), count (a.opt2), count (a.opt3), (a.opt4) count of feedback f, answers, teacher t, s of subjects, questions q where A.FEEDBACK_ID = 'FF1' AND fdate as 5 January 09 ' and the group a.question_id = q.question_id and t.teacher_id = f.teacher_id and f.feedback_id = a.feedback_id and f.subject_id = s.subject_id by t.teacher_name s.subject_name, q.question_id, q.question_desc, q.opt1, q.opt2, q.opt3, q.opt4 order of q.question_id
  
  But I need this area in my report. Can somone please help me out here!
  
  I tried to use SEPARATE, to_char, but in vain!
  
  Thanks a load!
  
  Kind regards

  Now,.

  If fdate is of type char or varchar2, then you can use this->

  select trunc(to_date(a.fdate,'dd-mon-yy')),
         t.teacher_name,
         s.subject_name,
         q.question_id,
         q.question_desc,
         q.opt1,
         q.opt2,
         q.opt3,
         q.opt4,
         count(a.opt1),
         count(a.opt2),
         count(a.opt3),
         count(a.opt4)
  from feedback f,
       answers a,
       teacher t,
       subjects s,
       questions q
  where A.FEEDBACK_ID = 'FF1'
  AND trunc(fdate) = '05-JAN-09'   -- As discussed earlier you can use between here
  and a.question_id=q.question_id
  and t.teacher_id=f.teacher_id
  and f.feedback_id=a.feedback_id
  and f.subject_id=s.subject_id
  group by trunc(to_date(a.fdate,'dd-mon-yy')),
           t.teacher_name,
           s.subject_name,
           q.question_id,
           q.question_desc,
           q.opt1,
           q.opt2,
           q.opt3,
           q.opt4
  order by q.question_id
  

  Or, if that is the date the reference->

  select trunc(a.fdate),
         t.teacher_name,
         s.subject_name,
         q.question_id,
         q.question_desc,
         q.opt1,
         q.opt2,
         q.opt3,

         count(a.opt1),
         count(a.opt2),
         count(a.opt3),
         count(a.opt4)
  from feedback f,
       answers a,
       teacher t,
       subjects s,
       questions q
  where A.FEEDBACK_ID = 'FF1'
  AND trunc(fdate) = '05-JAN-09'     -- As discussed earlier you can use between here
  and a.question_id=q.question_id

           q.question_id,
           q.question_desc,

  How do I get the date in the specified format without changing the NLS_PARAMETERS as shown below:

  As others have already pointed out, a date is not a format. You can't get a date in a specified format.

  If you want a character string that represents a date, you use the function TO_CHAR. In this case, it is not supposed to do since you already have the channel by hand. But you might

  SELECT to_char( to_date( '20090912', 'MMDDYYYY' ),
                  'MMDDYYYY' )

• Problem in TO_DATE...

  Hello
  
  I need to display the date and time using the to_date function.

• Potential problems with copy_table_stats.

  Guys,

  I have a table with the DDL below containing a huge number of records.

  CREATE TABLE APPEAL. CALL_DTL

  (

  DATE TIME STAMP,

  MSN VARCHAR2 (32 BYTE) NOT NULL,

  EVENT DATE NOT NULL,

  )

  PARTITION BY RANGE (EVENT)

  (

  CALL_P_01122015 PARTITION VALUES LESS THAN (TO_DATE (' 2015-12-01 00:00:00 ',' SYYYY-MM-DD HH24:MI:SS ',' NLS_CALENDAR = GREGORIAN ')),

  CALL_P_02122015 PARTITION VALUES LESS THAN (TO_DATE (' 2015-12-02 00:00:00 ',' SYYYY-MM-DD HH24:MI:SS ',' NLS_CALENDAR = GREGORIAN '))

  CALL_P_03122015 PARTITION VALUES LESS THAN (TO_DATE (' 2015-12-03 00:00:00 ',' SYYYY-MM-DD HH24:MI:SS ',' NLS_CALENDAR = GREGORIAN '))

  );

  We collect statistics for the 1st of the score of the month.

  BEGIN

  DBMS_STATS.gather_table_stats)

  ownname = > 'CALL. "

  tabname = > 'CALL_DTL ',.

  partName = > "CALL_P_01122015"

  estimate_percent = > 1,

  GRANULARITY = > 'APPROX_GLOBAL AND PARTITION,

  Cascade = > TRUE,

  degree = > 15);

  END;

  /

  And the stats will be copied in the rest of the partitions of the month.

  Start

  DBMS_STATS.copy_table_stats (ownname = > 'CALL')

  tabname = > 'PMS_CALL_DETAIL ',.

  srcpartname = > 'CALL_P_01122015 ',.

  dstpartname = > 'CALL_P_02122015');

  end;

  /

  Start

  DBMS_STATS.copy_table_stats (ownname = > 'CALL')

  tabname = > 'PMS_CALL_DETAIL ',.

  srcpartname = > 'CALL_P_01122015 ',.

  dstpartname = > 'CALL_P_03122015');

  end;

  /

  Start

  DBMS_STATS.copy_table_stats (ownname = > 'CALL')

  tabname = > 'PMS_CALL_DETAIL ',.

  srcpartname = > 'CALL_P_01122015 ',.

  dstpartname = > 'CALL_P_04122015');

  end;

  /

  ...

  ...

  Could someone advise if there could be potential problems with the copy of his stats?

  What I see, HIGH_VALUE and LOW_VALUE are the same for every single partition for the SQL below:

  Select nom_partition, HIGH_VALUE, LOW_VALUE from dba_part_col_statistics where table_name = column_name 'CALL' IN ("MSN");

  
  

  Will this result in CBO plan fetching suboptimal on SQL running on the table with predicate such as MSN and EVENT?

  Please suggest me resolution approaches.
  

  
  

  Thank you!!

  It will depend on (among other things), how use you it as a predicate and unique how the column is.

  If you try to filter using predicates of beach in function with a range outside the stats then the CBO will be predicate weak cardinalities and therefore will promote the access of the index and nested loops which leads to this.

  If you are filtering on equality predicates and the key is unique there should be no problem really.

  It will depend also on whether the request knows which partition will be scanned, otherwise it will use global statistics, which will be probably the same as a partition, but they could easily change if you were to collect stats on any other partition.

  You have an environment you can use a test and see approach?

• Problem I have TO solve with the query: PREV calculation to the current record

  Hi all

  My version of db:

  Oracle Database 11 g Enterprise Edition Release 11.2.0.3.0 - 64 bit Production

  I have the problem to solve with a request (MUST BE a SELECT statement), but I do not understand how... I tried with the analytical function but... not just:

  I have this table:

  rownum	KEY1	KEY2	A3	PERC	IMP
  1	A123	RISCP	01/01/2014	10	100
  2	A123	RISCP	02/01/2014	11	100
  3	A123	RISCP	03/01/2014	15	100

  Application of expected result:

  RESULTS	KEY1	KEY2	A3	PERC	IMP
  90	A123	RISCP	01/01/2014	10	100
  80.1	A123	RISCP	02/01/2014	11	100
  68.085	A123	RISCP	03/01/2014	15	100

  Starts recording with rownum 1 (the lower date with the same KEY) I do: imp - (100 imp * perc), where imp = 100 and PERC = 10, so the first result of the calculation is: 90

  
  

  Now I have to go to record 2, so I do 90 - 11%: imp - (100 imp * perc), where imp = 90 and PERC = 11, results is 80.1

  Now I have to go to the 3d recording, so I 80.1 - 15%: imp - (100 imp * perc), where imp = 80.1 and perc = 15, results is 68 085

  So I have to use the previous to the current PERC.

  I'm sure it's possible through a combination of funcion analytical!

  Thanks to anyone who can help me!

• Data parameter problem

  Hello

  I am facing a problem with the parameter Data;

  I can't able to query the data for different dates in the range, but I am able to query the data for the same date in the range.

  Dilip Manon

  As John pointed out, use the date data type to compare dates:

  Select RCT.GL_DATE in the RCT RA_CUST_TRX_LINE_GL_DIST_ALL

  where RCT.GL_DATE

  (between TO_DATE(:P_GL_DATE_LOW)), 'DD-MON-YYYY')

  (AND TO_DATE(:P_GL_DATE_HIGH)), 'DD-MON-YYYY');

  Using TO_CHAR to compare dates, not only do you risk to make mistake and forget certain values, but also in this case stop you an index on GL_DATE may be used.

• Equivalent OBIEE TO_DATE and SUBSTR functions

  I have the formula for the next column, which works correctly:

  SUM (CASE WHEN (TimeStampDiff (SQL_TSI_month, "Registration - College". "" Effective colleges F. ((("' Program Start Date ', current_date)) / 12 < 6 THEN 1 ELSE 0 END)

  
  

  I want to replace the current_date with scope of practice. Because the scope of practice is currently not in a date format (e.g. 201213, 201314, 201415), I need to use the TO_DATE and SUBSTR functions OBIEE equivalent to convert this field into a format that can be used by the TimeStampDiff function.

  The current (outside OBIEE) SQL for the conversion of the year at a date looks like this:

  To_date (substr (Fiscal_Year, 1, 4) |) '09', "YYYYMM")

  
  I tried to replace current_date in the column formula above by the following, but it didn't work:

  To this day (Substring ("registration - College". "D time". " "Exercise" FROM 1 to 4) | '09', "YYYYMM")

  TO_DATETIME (LEFT ("registration - College". "D time". " ("' Exercise ', 4) | ("/ 09/01 ', ' yyyy/mm/dd')

  Good course assuming that "registration - College". "D time". " "' Exercise ' is of type varchar, otherwise you will first need to cast as varchar or LEFT won't like it (but the error will tell you what the problem is exactly).

• Problem with procedure

  Hello world

  I created a procedure that takes 2 dates as parameters, and inserts the values of dates between the parameters in the table.

  create or replace procedure ENTER_DATES(START_DATE IN DATE, END_DATE IN DATE) is
  V_ENTERED_DATE date := START_DATE;
  begin
  LOOP
  if V_ENTERED_DATE <= START_DATE then
  insert into TEST_TABLE(NEW_DATE)

  V_ENTERED_DATE := TO_DATE(V_ENTERED_DATE) + 1;
  EXIT when V_ENTERED_DATE = END_DATE;
  end if;
  END LOOP;
  END;

  I have compiled the procedure and had no problem, but when I try to run the procedure. NEVER, THE EXECUTION ENDS.

  It of like I started and loop infinite.

  Please help me understand my mistakes.

  This stated case seems confused.

  What happens if your end_date has a share after midnght? He will never leave me.

  Why not just write:

  EVERYTHING V_ENTERED_DATE<= end_date="">

  values (V_ENTERED_DATE);

• the date conversion problem

  Hi friends,

  I have a problem with the conversion of the date in my PB.

  SELECT eff_dt, TO_CHAR (TO_DATE (eff_dt, 'Dd-mon-yy'), 'dd-mm-yyyy') DATE from une_table;

  It gives me o/p as -.

  DATE OF EFF_DT

  01.01.1950 00:00:00 01/01/2050

  as you can see here the year is wrong, while I convert the date that I use the substr() also to cut the year of first line, but it gives me the 50 i.e. onle last (YY)

  So, if someone can help me with this prob.

  If eff_dt is a column DATE, then stop calling to_date on it.

  If this is not the case, consider making it into a DATE column. If you are unable to do this, use the format mask appropriate when you call to_date

   where  Reynolds in ( '113' ) AND Rotomac in ( '418' ) AND (to_date(ins_date,'YYYY/DD/MM') >= to_date('01/90/2012','DD/MM/YYYY') OR del_date is null);
  

  ins_date is varchar2 which I convert it to a DATE using the to_date function.

  Why it does not work it only gives me error even if I put 90 MM?

  you have lines where this part:

  Reynolds ("113") AND Rotomac games ('418')

  and this part

  del_date is null

  is the problem?

  because you get only an error when the condition is evaluated is not the case if she didn't have to be evaluated...

  example:

  SELECT * FROM dual

  where 1 = 2 and sysdate > = to_date('01/90/2012','DD/MM/YYYY')

  will not return an error 1 is never equal to 2, so no matter what the condition after the and is...

• Problem with restore DB

  I backed up the database using sqldeveloper > tools > export databases > suckered into the sql file. But now I don't know how to restore, in particular tables, they contain important data. Database is 11g.

  -Now you can have a bit of a problem. Developer SQL creates just one (or more) files SQL according to the options you have chosen.

  If you put everything in a SINGLE file restore you what you want by finding and running portions of the file that you want to use MANUALLY.

  Here it is just a SMALL example of an 'export' for a file ONLY the SCOTT dept and emp tables and data. You can see how everything (TABLE DDL, DATA) is just mixed:

• '=' with to_date function fails to get results

  I have the table for more visits. my table has two fields survey_id (number) and visit_date (date).

  the visit_date also contain the time visiting hh.

  When I query the table to find information for a day and using the following qyery:

  Select survey_id, visit_date

  from my_table

  where visit_date = to_date('26/04/2010','DD/MM/YYYY');

  Therefore, no data found

  but when I used another query such as

  Select survey_id, visit_date

  from my_table

  where visit_date > to_date('25/04/2010','DD/MM/YYYY');

  There are records to date 26/04/2010.

  In other words, always when I query the table for a day using

  visit_date = to_date(:my_date,'DD/mm/YYYY');

  There is data in the table, I think there is problem of hh in the field of visit_date

  Oracle stores dates in digital form (I think 9-digit) format that includes both.

  When you use the operator = with a truncated string, it assumes zeros for the time elements.

  If your first query is looking for visits that have been at exactly midnight.

  Your options are to use the trunc function as suggested or use the syntax "between".

• TO_CHAR fucntion problem with dates.

  Hi all

  I tested the following problem with 10g and 11g databases, and the problem is the same.

  create table aa (a date);
    insert into aa values('23-Mar-2014');
   commit;
  

  now the following query gives no results

  select count(*) from aa
  where to_char(a,'dd-Mon-yyyy') >='23-MAR-2014' and to_char(a,'dd-Mon-yyyy') <='23-Apr-2014';
  COUNT(*)
  ----------
   0
  

  and the following query gives the results

  select count(*) from aa
  where a>='23-Mar-2014' and a<='23-Apr-2014'
  
  COUNT(*)
  ----------
    1
  

  Why?

  We need the to_char working for our criteria of search dot net application.

  kindly guide us.

  Thank you

  You're hurting. Why convert a date into a string of characters and try to compare it to another string? This is false.

  Insert into aa values('23-Mar-2014');

  should be

  insert into aa values (to_date (March 23, 2014 ',' MON-DD-YYYY "");)

  and your selection should be:

  Select count (*) in aa

  where a > = to_date (March 23, 2014 ',' MON-DD-YYYY') and to_date (April 23, 2014 ',' MON-DD-YYYY "")
