• History of backfilling with non-null values

  Hi gurus,
  
  in Oracle 11 g, which would be the best way to update a null with the next available non-null value?
  
  For example: in the code below, I need to update the null in 20130201 record (key = 1) (key date) with a value of 100 available at the next available date IE 20130203.
  Same key = 3 value will be updated with key = 4 value i.e. 200.
  

  1,ABCD, 20130201, NULL
  2,ABCD,20130203, 100
  3,ABCD, 20130205, NULL
  4, ABCD,20130207, 200

  Thank you

• validation working is not to count the non-null fields

  I have six fields on the screen, I want to check that at least 3 of them are filled (3)...
  I created a validation as follows to count the non-null fields... but it's not working...
  Please help solve this problem or recommend a better way to do this...
  
  
  declare
  number of question_count;
  Start
  question_count: = 0;
  If: p1_t_question_1 is null then
  null;
  on the other
  question_count: =: question_count + 1;
  end if;
  If: p1_t_question_2 is null then
  null;
  on the other
  question_count: =: question_count + 1;
  end if;
  If: p1_t_question_3 is null then
  null;
  on the other
  question_count: =: question_count + 1;
  end if;
  If: p1_t_question_4 is null then
  null;
  on the other
  question_count: =: question_count + 1;
  end if;
  If: p1_t_question_6 is null then
  null;
  on the other
  question_count: =: question_count + 1;
  end if;
  If: p1_t_question_6 is null then
  null;
  on the other
  question_count: =: question_count + 1;
  end if;
  
  If: question_count > 2 then return false;
  otherwise returns true;
  end if;
  end;

  I'll take a look a bit.
  In the meantime, check if the code as

  If the trim (both '%' from: p1_question_with_nul') = 'null '.

  help

  Ok. Take a look now. I used the function TRIM as shown above and also changed the comparison for questions 3 text based on ' if: p1_question_with_text is null'

  Seems to work now

• the non-null values insert select

  Please could you help me on this:

  INSERT INTO new_table (ID, hobby, country, internal_id, cat)

  SELECT ID, hobby, country internal_id,

  Max (CASE cat WHEN = 'ben' THEN 1

  WHAT cat = 'ale' THEN 2

  WHAT cat = 'inf' THEN 3

  WHAT cat = "cad" THEN 4

  WHAT cat = 'juv' THEN 5

  WHAT cat = 'sen' THEN 6

  WHAT cat = 'teacher' THEN 7

  END)

  Ancienne_table GROUP BY ID, hobby, country, internal_id;

  the lines on ancienne_table have duplicates regs as follows:

  ID	Country	Hobby	Internal_ID	CAT
  1	Oman	Rugby Union	63180	Juv
  1	Oman	Rugby Union	63180	Teacher
  1	Oman	Rugby Union	63180	Juv

  the request requires the output as follows:

  ID	Country	Hobby	Internal_ID	CAT
  1	Oman	Rugby Union	63180	7

  because cat = 'juv' (5) is less cat =' teacher (7).

  all columns are not null and the primary key of the new_table is ID + hobby

  The script displays the following output:

  01400 00000 - 'impossible to insert NULL into (%s)' because does not recognize the function max.

  Thanks in advance.

  Kind regards.

  Actually there are values not in the range of cat. There is an error in the old data table.

  I proceeded to remove the lines out of reach in the cat because column that are not relevant in this case.

  The parameters I use Oracle are:

  Oracle Database 11 g Enterprise Edition Release 11.2.0.1.0 - 64 bit Production

• Use Insert all but want only to insert records for non-null values

  Hi, New here and could use some help with my sql statement.  I have a portfolio with denormalized data table that has been inserted via .csv file.  It is a contract with a base, options and extensions.  I need to create a contract record, then a separate record in the table for each base/option/extension contract Details.  I use INSERT ALL so I maintain the CONTRACT_ID for the secondary table.  My problem is that my statement puts a line in the table of details for the null records, that I don't want.  (i.e. 123 contract has a Base, Option 1, Option 2 and Option 3, but I'm getting a line for these lines with dates more null for Option 4, Ext 1, Ext 2, Ext 3 and Ext 4).  I want to insert only when the % CTRT_STRT_DT is NOT NULL.  It will be different for each contract.  Where should I put the IS NOT NULL statement?  Here is my complete insert statement:

  You're close.  Basically, you add one when befire each Inserts lines.  Something like:

  INSERT ALL

  When the ctrt_id is not null then

  IN LRTC (PRGRM_OFC_TYP_CD, CTRT_NME, CTRT_ID, CREN_DT)

  VALUES (CTRT_ID_SEQ. NEXTVAL, PRGRM_OFC_TYP_CD,

  SPLS_SRVS_DESC, SYSDATE)

  -Contract detail for another period of performance data

  When the OTHER_CTRT_STRT_DT is not null then

  IN (CTRT_ID, CTRT_STAT_CD, CTRT_PER_NME, CTRT_DTLS

  CTRT_STRT_DT, CTRT_END_DT, CTRT_CURR_AMT,

  CTRT_NO, CTRT_VNDR_NME, CREN_DT)

  VALUES (CTRT_ID_SEQ. NEXTVAL, 1, 'Other', OTHER_CTRT_STRT_DT,

  OTHER_CTRT_END_DT, OTHER_CTRT_CURR_AMT,

  CTRT_NO, CTRTR_NME, SYSDATE)

  -Contract detail data for the reference period of performance

  When the BASE_CTRT_STRT_DT is not null then

  IN (CTRT_ID, CTRT_STAT_CD, CTRT_PER_NME, CTRT_DTLS

  CTRT_STRT_DT, CTRT_END_DT, CTRT_CURR_AMT,

  CTRT_NO, CTRT_VNDR_NME, CREN_DT)

  VALUES (CTRT_ID_SEQ. NEXTVAL, 1, 'Base', BASE_CTRT_STRT_DT,

  BASE_CTRT_END_DT, BASE_CTRT_CURR_AMT, CTRT_NO,

  CTRTR_NME, SYSDATE)

  You may need to adjust my predicates, but it should give you the idea.

• Return the first line with a non-null value in a column

  Hey there, gurus. Can someone give me a hand with this?
  
  I have a table with six columns: Class_ID, Course_ID, start_date, Last_Name, First_Name, company. When our students take a class and will fill in an evaluation form, they fill in the Class_ID Last_Name First_Name, and Company. The Course_ID and Start_Date are filled automatically based on the Class_ID.
  
  I am trying to generate a report that contains Class_ID, Course_ID and Start_Date, PLUS the value of the first not null in the column of company for a combination given to the three first columns. Here is my SQL that does not quite do the trick:
  
  Select distinct c.class_id, c.course_id, c.start_date, p.company
  class c, person p, student s
  where substr (c.course_id, 1, 3) = "OBI".
  and c.start_date > = SYSDATE-30
  and c.class_id = s.class_id
  and s.pid = p.pid
  order start_date, company, class_id, course_id
  
  At present, if in a given class, a student entered "CCCC" under the name of the company and another entry "Collin Co Comm Coll" and another between "Collin College", I would get three rows of this class when you use the SQL above. I want just one line. I don't really like which company names gets selected - one of them will be great for our needs. I just need to see a line for each class_id and single value that some students entered the area of the company. And I guess I have to say that if no student fills in the name of the company I need to see the value null, because I need to see the line no matter what.
  
  Looks like some sort of funky outer join or a coalesce, but it is beyond my ability to understand.
  
  Now I get this:
  During class 1234 SQL271 Date 22/07/2013 company XYZ Inc.
  Made up of class 1234 SQL271 Date 22/07/2013 company XYZ
  1234 SQL271 Date 22/07/2013 company XYZ, class
  
  What I want:
  Class 1234 SQL271 22/07/2013 Date course XYZ Inc. or one of the other 2
  
  Thanks in advance!

  select c.class_id, c.course_id, c.start_date, max(p.company) company
  from class c, person p, student s
  where substr(c.course_id,1,3) = 'OBI'
  and c.start_date >= SYSDATE-30
  and c.class_id = s.class_id
  and s.pid = p.pid
  group by c.class_id, c.course_id, c.start_date
  order by class_id, start_date, course_id
  

  Or if you want to list all businesses, you can use LISTAGG if you're on the latest version of ORACLE

  Insert ex1 (null).
  
  insert into ex1 (e)
  
  number of will be: 2
  
  I can easily find the value "e".
  
  so my question is:
  
  How can I find null values in the table and I want to remove the null values from the table.

  It depends on what you expect. If you issue count (*) you ask Oracle "how many lines there. If you issue a County () you ask Oracle 'how non null values for are there. "

  delete from 
  where  is null;
  

  Ideally you would simply place a NOT NULL constraint on the column in question, thus prohibiting NULL values into the system (assuming that your business needs, it is that the column MUST always have a value).

• Remove data with null value

  Hello

  I'm using Oracle 11 g. I have a table with an id of 3, node, the value column. Combination of the column id and node, that must be taken account for deletion on the registers.

  Here, I need to delete lines with the NULL value in the value column. If for a combination of id and node with non-null values, then I need to delete rows with a null value for this combination.

  If the combination of id, node is not null value then this records should not delete.

  Below table, I need to remove the second row, for which is a value not zero VOICE CAL '10' is there, so I need to delete the row with null values. (VOICE, CAL, NULL)

  Network, FL, there is no value is non-null then I should NOT delete this line.

  This table is to have 100 s of this association, we can delete data in a single delete query?

  Or how I can delete rows with nulls for this combination.

  Tab1

  VALUE OF THE NŒUD ID

  VOICE CAL 10
  VOICE CAL NULL
  NETWORK NULL FL

  Thank you

  Thank you

  You can do this in a single DELETE statement (it is not a request), using an EXISTS or IN the subquery.  For example:

  REMOVE table_x m

  WHERE the value IS NULL

  AND THERE ARE)

  SELECT 0

  FROM table_x s

  WHERE s.id = m.id

  AND s.node = m.node

  AND s.value IS NOT NULL

  )

  ;

  If you would care to post CREATE TABLE and INSERT instructions for the sample data, and then I could test it.

• Add/assign value to non-null text values

  I have a database that stores the (item) values for each day of the month - for example if a person is OFF or VAC (holiday).  So, it should look like this:

  Name	LUN	Mar	Wed
  John Smith	OFF	OFF
  Charlie Murphy		TRN
  Ricky James	VAC	VAC	VAC
  TOTAL	2	3	1

  So, I need the line 'TOTAL' to add the columns whose value is non-null.  I thought maybe I could somehow assign a value of 1 for each of the columns, and then perform a sum.

  If anyone can help in a solution of Coldfusion or SQL Server 2005?  Thank you.

  I thought maybe I could somehow assign a value of 1 for each of the columns, and then perform a sum.

  Yes, you can use a CASE statement to return 1 or 0.  Then pack them in a SUM (.).

  SELECT SUM (CASE WHERE ColumnName IS NULL THEN 0 ELSE 1 END) AS ofcases...

• Count of NOT NULL or NOT

  Hi all

  I am trying to run a query to count how many reports in my system have a valid "RunNumber" in a specified amount of time.  To do this, I need to eliminate some bad entries and null values that are entered in the column RunNumber

  My query looks like this:

  Select round (count (a.ReportNumber) / tot_reports * 100, 2) PERCENTAGE

  report a, b of EMS,

  (select count (ReportNumber) report tot_reports, ems WHERE report.id = emss.id and insertdate BETWEEN 1st January 13 'AND January 31, 13')

  where a.id = b.aid and a.insertdate BETWEEN January 1, 13 'AND 31 January 13'

  and (b.RunNumber not in ('0000000000', 'N/a', 'NA', 'NONE', 'NONE GEN"," NOT Available. ","NOT AVAILABLE","NOT PROVID","REFUSAL","DENIED", 'UNK', 'UNK',"UNK.", 'UNK000',

  ("UNKKNOWN", "UNKNOWN", "UNKNOWN", "UNKNOWN", "UU", "XX", "XXX", "XXXXX", "XXXXXX") or b.Runnumber is not null)

  Tot_reports group;

  When I run this query, I get 97.73%

  There are 44 total records and 1 card has a null value, and 3 contain a 'bad data' I'm trying to weed out.  So techincally the % should be 40 files with a 'good' runnumber.  And this percentage 40/44 * 100 = 90.9%

  I know that the null value is shaking the calculation but I don't how to work around it.  Any help will be greatly appreciated.  Thanks in advance.

  Thank you very much.  This helped me wrap my head around what I was trying to accomplish and it worked perfectly.

• PersistentStore.getPersistentObject returns the null value?

  I use a random key to retrieve a shape of the object PersistentStore

  persist is PersistentStore.getPersistentObject (KEY);.

  Works fine on the Simulator (OS 5), when I take the code signed to the device (BB OS 5.0 Bold 8900)

  For some reason, it returns null, without exception. Thereafter any API I inoke on PersistentStore / persist returns null without exception persist even when the null value.

  I don't know if it's one thing to eclipse debugger, but even if the debugger shows that objects are null. Controls null applied in the code seems to fail, what does code see these objects as non-null. Pheww! How is it possible.

  In this code still shows up as null, then safetyTable and orderedkeys. However, the value null check in the failure code.

  At a later stage in the code, when I try to access orderedkeys are null again! Are struggling with this problem for two days, all the pointers would be very comfortable.

                      persist = PersistentStore.getPersistentObject( KEY );
                      persistOrderedKeys = PersistentStore.getPersistentObject(KEY_ORDERED_KEYS);
                      safetyTable = (Hashtable)persist.getContents();
                      orderedKeys = (Vector)persistOrderedKeys.getContents();
                      if (safetyTable == null)
                      {
                          safetyTable = new Hashtable();
  
                          persist.setContents(safetyTable);
                          persist.commit();
                      }
  
                      if (orderedKeys==null)
                      {
                          orderedKeys=new Vector();
  
                          if (safetyTable.size()>0)
                          {
                              Enumeration addressKeys = safetyTable.keys();
                              while(addressKeys.hasMoreElements())
                              {
                                  orderedKeys.addElement((String)addressKeys.nextElement());
                              }
                          }
                          persistOrderedKeys.setContents(orderedKeys);

• Separate s processed NULL values in indexes

  http://docs.Oracle.com/CD/B19306_01/server.102/b14220/schema.htm#i20690

  Indices and null values

  NULLthe index values are considered as distinct except when all non - NULL in two or several lines of an index, the values are the same, in which case the lines are regarded as the same. Therefore, UNIQUE i index prevents the lines containing NULL values to be treated as identical. This does not apply if there is not a no - NULL values - in other words, if the lines are fully NULL .

  The bold part: who's trying to tell me that the lines for the NULL indexed lines, that if these indexed 2 NULL values maintain the same values for the rest of the line that oracle treats as unique to them?

  That being said, the bold part is qualified with this statement:

  Therefore, UNIQUE i index prevents the lines containing NULL values to be treated as the same.

  
  

  
  

  
  

  In fact all this 2 average values in a single column being zero, with the rest of the line being exactly the same, is not treated as identical.

  
  

  I'm sure that's what the DOC tries to explain.
  

  Consider that you have a composit index SINGLE a two columns COL1 and COL2. And you want to insert some values like this

  ROWNUM COL1, COL2
  ------- -------- --------
  1 1 NULL
  2 2 NULL
  3 3 NULL
  4 3 NULL

  NULL values in the index are considered to be separate

  This statement indicates that NULL in COL2 values are considered to be UNIQUE values. If the NULL in COL2 ROWNUM 1, 2 are considered to be two different values.

  But the following statement

  except in the case of all values not NULL in two or more rows of an index are the same, in this case, the lines are considered to be identical

  This statement says ROWNUM 3, 4 for COL1, where they have identical values, where the NULL in COL2 value are not considered as UNIQUE values but as identical. That's why the 4 ROWNUM insert will fail with UNIQUE constraint violation.
