• Update a field with different values of several tables

  Hello
  
  I have a table named AAA with 2 fields id and structure.
  And then I have other 3 tables with 2 fields id1 and structure1 id2, table1 and table2, id3 and structure3 to table3 organized.2.
  
  The number of AAA id is equal to the sum of the IDS of table1, table2, table3: #id = #id1 + id2 # + #id3).
  
  I want to update the structure of AAA table with values as well as field:
  where AAA.id = table1.id1-> AAA.structure = table1.structure1
  where AAA.id = table2.id2-> AAA.structure = table2.structure2
  where AAA.id = table3.id3-> AAA.structure = table3.structure3
  
  Can someone help me?
  
  I have Oracle11gR2.
  
  Thank you in advance.

  Is there a parent - child relationship kind of thing in your file structure?

  Row containing sales, purchases etc. is the parent and the tracking records are the child records, until we meet any record type 'Bill of sales, purchases',? In addition, tried to use "conditionValue" and "startsWith" and it did not work... Is it?

• reuse of filters with different values

  We have a usage scenario where the same filters will have to be applied several times with different values. Looking the javadocs, it seems like there is no way to change the values of pre-packaged filters (EqualsFilter, GreaterFilter etc.). Is that correct or is there a way to do it? I see that if we use CohQL, we can use bind variables to do this. However, the use cases we should rather just more complex extractors ReflectionFilters.
  
  In addition, there no performance impact by using CohQL against java constructs directly?
  
  Thank you
  Manju.

  Hi Manju,

  While it is true that you cannot change values in the built in filters, even if you could it wouldn't make you save a lot on the construction of a new filter every time. I guess that if you build a very large number of filters, then you're going to create more garbage, but that shouldn't be a problem either. Some of the more specialized filters also contain State so that you do not want to resuse them.

  The main performance issue I know with CohQL which is only creates extractors of reflection so won't enjoy all serialized POF values you have. If you have indexed each value you want to query on using the same extractors relflection then it would help, but again, this means that everything you deserialization of the values for the query or insert to update the index.

  Kind regards

• Pulling on the first line with a value of repetition

  Hello
  We use the Oracle 11.1.
  
  We have a table of postal codes.
  
  We have several lines for each zip code because we have different areas that use the same zip code.
  
  We want to reduce the lines of a line by zip code. But they said use they want to keep the fields that differ (neighborhood of the exodus).
  
  Then they said "Just take the first value of each."
  
  This code reduces the postcodes of a line by postal code, but as you can see I replaced the field with the name of the field values.
  

  SELECT distinct  ZIPCODE, CITY, STATE, COUNTY, AREACODE, 'CITYTYPE', CITYALIASABBREVIATION, 'CITYALIASNAME', LATITUDE, LONGITUDE, TIMEZONE, ELEVATION, COUNTYFIPS, DAYLIGHTSAVING, PREFERREDLASTLINEKEY, CLASSIFICATIONCODE,
             MULTICOUNTY, STATEFIPS, 'CITYSTATEKEY', 'CITYALIASCODE', 'PRIMARYRECORD', CITYMIXEDCASE, 'CITYALIASMIXEDCASE', STATEANSI, COUNTYANSI
      FROM   zip_code
  GROUP BY   ZIPCODE, CITY, STATE, COUNTY, AREACODE, CITYTYPE, CITYALIASABBREVIATION, LATITUDE, LONGITUDE, TIMEZONE, ELEVATION, COUNTYFIPS, DAYLIGHTSAVING, PREFERREDLASTLINEKEY, CLASSIFICATIONCODE, MULTICOUNTY, STATEFIPS,
             CITYALIASCODE, PRIMARYRECORD, CITYMIXEDCASE, STATEANSI, COUNTYANSI
  order by zipcode; 

  How should I take either one record per postal code with the first value in these fields or
  
  How should I take the first record for each zip code?
  
  either way works for me.

  Hello

  This is called a Query Top - N , and this is a way to do it:

  WITH     got_r_num     AS
  (
       SELECT     z.*
       ,     ROW_NUMBER () OVER ( PARTITION BY  zipcode
                                 ORDER BY          city
                           ,                ...   -- add tie-breakers here
                         )      AS r_num
       FROM    zip_code
  )
  SELECT     *     -- or list all columns except r_num
  FROM     got_r_num
  WHERE     r_num     = 1
  ;
  

  You can simply use MIN or MAX on the columns, as the line with the name of the minimum city do not lowest have area code or the longitude. The above method preserves the first line of each zip code intact, where the 'first': the first in order of aphabetic by the name of the city. If it is not unique, then you may want breakage to the analytical ORDER BY clause.

  If you are deleting rows, you can use this in a NOT IN subquery. If you copy lines to a new table, you can use the query above in an INSERT statement.

  I just see Polywog response:

  You can use the rank or rownumber function...

  If I understand the problem, you don't want to use RANK in this particular case. When there is equality, GRADE will assign 1 to all the contenders. I think the whole point of this thread is that you exactly want a #1 in each zip code, which is what ROW_NUMBER, but not RANK, guarantees.

• Several channels with different frequencies

  Hello

  I use card NI USB-6221.

  The C API using, I need to generate 6 digital output channels, with frequencies of diffrenet and Heavy duty.

  To be more precise, the 2 are totally identical, but I need them to be reversed, and the other 4 are similar to another, but should be shifted in time (I.e. There is a delay between each of the channels).

  I used the 2 channels of CO that the USB-6221 takes charge for the first two signals, and it works very well (the two signals are synchronized and are reversed).

  Now I need an additional 4 channels for the other vague square.

  I saw an articale NOR by JohnP web site with the title:

  Generate multiple channels of digital output with different frequencies and Heavy Duty

  The following example shows how to create and generate a digital with the non-regeneration wave form so that you can change the frequency and the duty cycle on the fly with the M Series DAQ hardware X.  The example uses output digital rather than counters to achieve this, so if you need more output than the available counters, it would be a good option (Note: on the materials of the M series an external sample clock must be provided, this may be caused by one of the counters if you want).

  that seems to be exactly what I need, but the examples are for LabView which I did not.

  Can someone explain how to do this with the C functions?

  Best regards

  Danny.

  Hey Danny,

  The important thing to note is that you can clock of arbitrary digital waveform (up to 1 MHz on the 6221).  The real data acquisition programming is pretty easy once you have the waveform.  My Example LV used LabVIEW Base generating function VIand then converted to a digital waveform to generate the signal from each channel.

  The functions of LV helped tremendously with to achieve the waveforms to be updated on the fly (the basic function generator keeps track of phase for you).

  If you do not need to be updated on the fly, then the construction of the waveform in C should not be too bad.  For example:

  P0.0 [1 1 1 1 1 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0] * 1

  P0.1 [0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 1 0 0 0 0] * 2

  P0.2 [0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 1] * 4

  P0.3 [1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1] * 8

  [9 9 9 9 9 3 3 3 3 3 6 6 6 6 6 12 12 12 12 12]

  The table above U8 would give you 4 output waveform of 50% duty cycle at Fs/20, shifted 90 degrees to eachother.  The lines would be p0.0 by p0.3 (the bit rate of the U8 corresponds to what line goes high).

  Best regards

  When you try to update the column of file type for all records-

  Update NewTable set FileType = (select FileType from ancienne_table where Fileno = newtable.fileNo and folder = NewTable. File);

  
  

  It would work fine for all other cases with the exception of the first two that are currently double.

  It won't work of course because it would give - "row subquery returns more rows" error because of these duplicate records.

  I'm trying to update the file type column to the first two rows with values 'Type1' and 'Type2 '.

  Out of these two files, it won't matter whose recording of newtable is updated with 'Type1' and you get 'Type2 '.

  Please help with ideas around update duplicate records with the ancienne_table-specific data into newtable.

  Him below will work... You can update using ROWID, but the lines are duplicated. Must therefore first to define any id for these two lines replicated using row_number and then correspond with rn for the IDENTIFIER specified.

• Return only the columns with different values.

  Hi all
  
  I am trying to solve a seemingly trivial problem but can't seem to get any clear answer anywhere in any forum. Consider a single table with 5 columns and only two lines:
  

  row_id           first_name         last_name        age            gender
  1                    John                  doe               27             M
  1                    Jane                  doe               27              F  

  Assume that there is no primary key or any other constraint. Also assume that there are only and only two lines of this table. So I need basically a query that, overall above lines, would return first name and sex, because they are only different columns in two lines, as well as their values. Even if I can get sort of column names that are different and that would be enough that I can easily access the values later. It is also important to remember that I may not know the names of the columns in the columns, so basically, somehow, I use user_tab_columns in the process.
  
  Any help appreciated.

  Hello

  The exact release could be just a varchar variable that lists all the columns that have different values with each column name separated by commas. We'll call the query you want as a QUERY. So, if I do something like

  Select the REQUEST of double; Output should be: 'first_name, equality of the sexes. Is this possible?

  In this case:

  SELECT     RTRIM ( DECODE (a.row_id,     b.row_id,     NULL, 'row_id,')     ||
                  DECODE (a.first_name, b.first_name, NULL, 'first_name,') ||
            DECODE (a.last_name,  b.last_name,  NULL, 'last_name,')  ||
            DECODE (a.age,        b.age,          NULL, 'age,')      ||
            DECODE (a.gender,     b.gender,     NULL, 'gender,')

  FROM     rhit_table_x  a
  JOIN     rhit_table_x  b  ON  a.ROWID     < b.ROWID
  ;
  

  Output:

  DIFFERENT_COLUMNS
  ---------------------------------------
  first_name,gender
  

  This assumes that you have really a table, then you can use ROWID to distinguish the lines, since there is no primary key.
  If this isn't the case, you first assign ROW_NUMBER in a subquery.

• Need to update several lines in a multi-line table in another

  I came to the conclusion that I can't do that because of the absence of a unique key that is related, but maybe you can help me with a solution. I tried all of the solutions posted here, but they do not work in my scenario. I have codes in a table that is a list of codes to the related market which they should be used for. I have a second table of customers who do not have the code assigned to them until they are sent to an advertisement. This table has the market_id for each customer and the table of codes has the market_id associated with each code. I want to update the customer table with one of the associated with the market_id mergecodes - but between the two tables you isn't a unique key to connect. I thought I could just update the records which had corresponding market_ids, but nothing works. In the two tables below, I want to be able to update t3tm.mergecode with one of the mergecodes that has the same market_id ("Austin") in t3mc. It does not matter that it is associated with a particular customer.
  
  {code}
  
  create table T3mc (use of mergecode varchar (10), market_id varchar (25), week number, varchar2 (5));
  
  Insert into T3mc values ('A8976","Austin", 2,");
  Insert into T3mc values ('A8988","Austin", 2,");
  Insert into T3mc values ("A9900", "Houston", 2, ");
  commit;
  
  create table T3tm (name varchar (20), market_id varchar (25), mergecode varchar (10), identification number);
  
  insert into T3tm Values ('Smith', 'Austin' ", 1);
  insert into T3tm Values ("Jones", "Austin", ", 2);
  commit;
  {code}
  
  {code}
  Select * from T3mc;
  MARKET_ID, WEEK, USED, MERGECODE
  Austin 2 A8976 (null)
  Austin 2 A8988 (null)
  Houston 3 A9900 (null)
  Select * from T3tm;

  For a group 18345, there are 10 users and this is the reason why I get a multiple user records.
  
  I can't avoid these last three columns, because I have to show these values in the application.
  
  In my opinion, the UNION is at the origin of the problem. Can I replace the UNION here? Please share your ideas on this.

  Hello

  because I have to show these values in the application.

  What is your problem then? If you simply issue a SELECT statement to application code or send the data back to REF CURSOR, it will be quite OK to have several lines. That's what the SELECT statements are for: to return sets of results with several lines.
  So, could not explain your problem more in detail please? If you get an error somewhere, provide the code causing the error and the error message (it is probably ORA-001422 exact extraction returns several lines somewhere in PL: / SQL, isn't it? then post here).

  In my opinion, the UNION is at the origin of the problem. Can I replace the UNION here? Please share your ideas on this.

  Us don't know not the answer to this question, because no one here knows your needs (what you need).
