SQL - connect by level problem

Hello

Under query returns only first 50 records but his having 233 files.

SELECT TO_CHAR (INN. START_DATE + LEVEL-1, ' DD/MM/YYYY') GENERATION_DATE OF
(SELECT TO_DATE (3 JULY 2011 ', ' DD/MM/YYYY') START_DATE, TO_DATE (OCTOBER 25, 2011 ', ' DD/MM/YYYY') END_DATE DOUBLE) INN
CONNECTION OF LEVEL between 1 and INN. END_DATE-INN. START_DATE + 1;


What is the exact problem in the operator level. Please suggest me.

  • Generation SQL line with connection by level

    Hello

    I'm looking for generate lines based on a quantity of part numbers.  I have looked all around several techniques for the generation of the line, but have failed to address this problem.  The current method, it seems pulls a permutation of all possible combinations, and the result is rising quickly to millions / billions of documents... which is not the answer.  Someone out there who could help writing a query to do this?

    What I try to achieve if a quantity of part 5, I want to display 5 Qty 1 documents.  If the Qty 12, then 12 Qty 1 documents.  So on and so forth.

    Out Oracle 10.2.0.4 operation

    Sample data:

    create table test (part varchar2 (20), number of quantity);

    Insert test values ('WIDGET', 12);

    Insert test values ('FOO', 5);

    Insert test values ('THING', 3);

    Insert test values ("WAD", 8);

    commit;

    -This query does not work... I think it's getting all the possible permutations

    AND PRIOR SYS_GUID () IS NOT NULL

    i  tried my level to understand it but couldn't
    
    Please explain  how it works
    

    Please only put code in tags code, otherwise it's hard to see what you're asking.

    In response to your question look at the query...

    SQL> select regexp_substr(str, '[^,]+', 1, level) val
      2      from (select 'a,b,c,d' str from dual)
      3   connect by level <= length(str) - length(replace(str,','))+1
      4  /
    
    VAL
    -------
    a
    b
    c
    d
    

    OK, so clearly it's split the string anywhere where there is a comma, then, how he does it.

    Firsly we look at connect by clause it when we use it as a generator of line...

    SQL> select level from dual connect by level <= 4;
    
         LEVEL
    ----------
             1
             2
             3
             4
    

    Now, look at how the number 4 is calculated from the string...

    SQL> select length('a,b,c,d') - length(replace('a,b,c,d',','))+1 from dual;
    
    LENGTH('A,B,C,D')-LENGTH(REPLACE('A,B,C,D',','))+1
    --------------------------------------------------
                                                     4
    

    ... looking at the length of the string and the length of it without comma, we can determine how many commas are in the chain and the surmize that there must be 1 more value there are commas.

    Now look at the regular expression...

    SQL> select regexp_substr('a,b,c,d', '[^,]+', 1, 1) from dual;
    
    R
    -
    a
    
    SQL> select regexp_substr('a,b,c,d', '[^,]+', 1, 2) from dual;
    
    R
    -
    b
    
    SQL> select regexp_substr('a,b,c,d', '[^,]+', 1, 3) from dual;
    
    R
    -
    c
    
    SQL> select regexp_substr('a,b,c,d', '[^,]+', 1, 4) from dual;
    
    R
    -
    d
    

    The 4th parameter of the regexp_substr function is the 'presence' of the search string to return.

    The actual regular expression itself is looking for 1 or more characters (sign +) who are not (the ^ symbol) a comma.

    Is that more clear?

  • Problem with connection by level

    Hello


    My desired goes something like this: I would like to generate the dates of hiredate to systdate with an interval of one month. The code that I have to return works well for single empno. I want to generate the dates of hiredate to sysdate with a gap
    one month for all employees (empno). Commenting on the code to find out where empno = 7369 does not work and the system a lot of the CPU usage.

    Hiredate were suppose to be to_date('01-jan-10') for empno = 7369

    examples of code goes something like this:
    select ADD_MONTHS(trunc(to_date('01-jan-10')),LEVEL-1)
    from dual
    connect by level <= trunc((sysdate-to_Date('01-jan-10'))/30 )
    code for the emp table
    select ADD_MONTHS(trunc(hiredate),LEVEL-1)
    from employee
    where empno = 7369
    connect by level <= trunc((sysdate-trunc(hiredate))/30 )
    Please advice

    You should stay with double to generate numbers. You can use the caluase WITH to create a table that contains only the relevant dates.

    The min max values for the datatab ann might be emp Subselects.

    example not tested

    with datatab as (select ADD_MONTHS(trunc(to_date('01-jan-10')),LEVEL-1) mon
                           from dual
                            connect by level <= trunc((sysdate-to_Date('01-jan-10'))/30 )
                           )
    select *
    from employee e
    join datatab d on e.hiredate <=d.mon
    where empno = 7369;
    

    Well, there are other ways to do it. Maybe you can provide some examples of data and also some of the desired output.

    I googled on this topic but everywhere I could find only employee and manager problem that will be solved by query below.
     SELECT employee_id, last_name, manager_id

    Employees
    CONNECT BY PRIOR employee_id = manager_id;

    But if we just query as below, we can get the employee and his manage without CONNECT BY.

    SELECT employe_id, last_name, manager_id
    Employees;

    In fact, those who are not the same.
    If you use the standard table of hr.employees, the CONNECT BY query above returns 315 lines, but the secoind query return lines only 107.

    CONNECTION is useful to show the recursive relationships. It can show you, for example, not only that reports directly to a data manager, but the whole hierarchy of persons under a given head. For example, the following shows the hierarchy starting with an employee named "Rooster":

    SELECT  employee_id, last_name, manager_id
    ,     LEVEL                         AS lvl
    ,     SYS_CONNECT_BY_PATH (last_name, '/')     AS path
    FROM    hr.employees
    START WITH      last_name          = 'De Haan'
    CONNECT BY       PRIOR employee_id      = manager_id;
    
    SELECT     SYSDATE - SYSDATE-41 + 1
    FROM DUAL;
    

    Output:

    EMPLOYEE_ID LAST_NAME  MANAGER_ID LVL PATH
    ----------- ---------- ---------- --- --------------------------
            102 De Haan           100   1 /De Haan
            103 Hunold            102   2 /De Haan/Hunold
            104 Ernst             103   3 /De Haan/Hunold/Ernst
            105 Austin            103   3 /De Haan/Hunold/Austin
            106 Pataballa         103   3 /De Haan/Hunold/Pataballa
            107 Lorentz           103   3 /De Haan/Hunold/Lorentz
    

    Very briefly, here's how it works.
    The result set of a query CONNECT BY is the UNION ALL of several queries, all sharing a common SELECT clause.
    Any line that meets the conditions of the START WITH clause is supposed to be at LEVEL 1. So you can think of the first branch of the UNION of ALL being (in this case):

    SELECT  employee_id, last_name, manager_id
    ,     LEVEL                         AS lvl
    ,     SYS_CONNECT_BY_PATH (last_name, '/')     AS path
    FROM    hr.employees
    WHERE   last_name     = 'De Haan'
    UNION ALL ...
    

    Other rows in the result set will be LEVEL = N if the conditions of the CONNECT BY clause, where the PRIOR operator refers to any line level = N - 1.
    For example, the line with name = "Hunold" satisfies the condition to connect BY when the FIRST line is the line where last_name = "Rooster", Hunold is in the game with the LEVEL of results = 2.
    Another example: the line with name = 'Lorentz' meets the condition to connect BY when the FIRST line is the line where last_name = "Hunold", Hunold is in the result set with LEVEL = 3.
    This is a classic example of a tree structure, where the rows in the table are connected to other lines in a parent-child relationship. In a tree, each row has 0 or 1 of the parents, but a line can have any humber children. Haan has 0 parent and 1 child (that is, Hunold). Hunold has 1 parent (De Haan) and 4 children. CONNECT BY queries are useful to deal with the trees like this, especially when the parent-child relationship may extend to a number any levels.

    Other queries is obtained to connect by is below, but he could not also include:

    Select the level - 1 the_date + SYSDATE-41
    of the double
    connect by level<= sysdate="" -="" sysdate-41="" +="">

    I don't understand whether you.
    SYSDATE-SYSDATE is just 0
    0 - 41 + 1 is just-40, so you might as well say:

    select SYSDATE-41 + level - 1 the_date
                                from dual
                              connect by level <= -40;
    

    In addition, LEVEL is always a positive integer, then the CONNECT BY State will never have the value TRUE, and if the CONNECT BY clause can never be TRUE, there is no reason to have a CONNECT BY clause.
    A more reasonable request is:

    SELECT     SYSDATE + LEVEL - 1     AS the_date
    FROM      dual
    CONNECT BY     LEVEL     <= 4     -- or any positive number
    ;
    

    which produces this output, the given number of days (4 in this example) from today:

    THE_DATE
    --------------------
    06-Dec-2011 11:08:24
    07-Dec-2011 11:08:24
    08-Dec-2011 11:08:24
    09-Dec-2011 11:08:24
    

    This is a very common way to generate a Counter of Table (a table, or, as in this case, a result set, that matters). For example, if you need for the aggregates per day in a table and you want to show 0 for days that never exist in the table, then you outer join in a table of counter like the one shown above.
    This is a common use of CONNECT BY, but this is an unusual exception to the rules that is prohibited govern CONNECT BY queries. I suggest you uderstand how the query on hr.employees, above, the work before you start trying to figure out how it works.

    You were on the right track with your first message.  The problem with this request was that you were each pair of words:

    • Word 1 and 2,
    • Word 2 and 3,

    Here's a way to do it:

    WITH the data AS

    (

    SELECT ' abc 11 12 11 22 33 kbc vbc wtc mbc mbc 17 45' AS str kbs

    Are you regular expressions of course are initially slow Paulzip query?  That's maybe something about your data you have not shown or explained.  As said by ground, you must always follow the Forum FAQ:

    Re: 2. How can I ask a question in the forums?

    so that people who want to help you can recreate the problem and test their ideas.

    In addition, the sample data (CREATE TABLE and INSERT statements), be sure to upgrade your version of Oracle.  A recursive (available in Oracle 11.2 and upwards) WITH clause might help in this problem. or maybe CROSS APPLY (Oracle 12.1) would be useful.

    Simplify the prblem as much as possible; for example, you generally need not show all columns in your actual tables, only those involved in the problem.  But make sure that you validate the example data illustrate the real problem.

    How to achieve the same thing for several input lines?
    I know I can do it in PL/SQL using plan either pl or just a function in the pipeline, but I prefer a clean if possible SQL.
    I tried to do in a cross join test3 and (select different values of double the test3 table) and other versions, but all with syntax errors
    with tal as
    (
    select * from
    (select a.*, rownum rn
    from test3 a)
    where rn < 3)
    ------
    select * from test3 cross join table

    select tekst, level ,

    from dual
    connect by level < length(tekst)
    )
    ;
    Oracle version will be 10.2 and 11 +.

    I think it's kind of what you're looking for:

    Robert,

    I wish I had a better explanation for you, but I know something again with 4.1 broke this trick union for tabular forms. I had to do a dynamic action that runs when the page loads and calls the javascript function of the: AddRow(). I think it has something to do with the validation of the form in a table, but I'm not sure.

    See you soon,.

  • Connect by level using the count of the records collection

    Hello:

    PROBLEM:
    ...
    ), (select rownum number months of double connect by level < = Cnt)

    Causes not valid ORA-00904 identifier. Why can I not use "Cnt" of my main as request by using a constant in the works?

    The value of count is determined for each date range in the section, I return the records that I need?

    Thank you, Sidney

    BACKGROUND:
    I have to be able to display a list of tax returns to my users and the status of these statements. There's no physical feedback so it is necessary to create data dynamically records using appropriate selection. It's not hard and I thought that would be enough to use a connection by level to give me the date, statements of information so that I can calculate and display the individual. However oracle gives me an ORA-00904 when I try to send the "Cnt" value to connect by level. Everything works fine when I provided a constant instead of "CNT". The "CNT" value is determined by a complex process that calculates start and end for several types of return dates, etc as well as the number of periods and frequency of production. The data must be generated dynamically using a master record, which then gives the history of coding in which my collection of basic records is selected. Here is the result of this process:

    TaxpayerNo, TaxClass TaxCode, FilingFequency, StartDate, StopDate, Cnt, frequency

    10 S 1 M 12-18 6/1/2007-11/30/2008
    10 S 2 M 12 10 30/11/2008-9/30/2009
    10 S, 2 Q 4 3 11/30/2010-8/18/2011
    L 10 8 6/1/2007 9/30/2009 3 1
    L 10 8 11/30/1 / 2010 8/18/2011 1

    According to the results, I have needs a record for each every month, quarter, etc. ie:

    10 S 1 M 6/1/2007 11/30/2008 18 12 6/1/2007
    10 S 1 M 6/1/2007 11/30/2008 18 12 7/1/2007
    10 S 1 M 6/1/2007 11/30/2008 18 12 8/1/2007

    A technique like this should solve your problem.

  • Connect by PRIOR vrs Connect by LEVEL

    Hello

    I'm trying to understand the difference between CONNECT BY PRIOR and CONNECT BY LEVEL

    I know that CONNECT BY PRIOR is basically specifying a hierarchy and which column / field is the parent (using the PRIOR)

    for example

    SELECT employe_id, employee_name, level

    Employees

    CONNECT BY PRIOR employee_id = manager_id;


    Q1. What is CONNECT BY LEVEL (for example as shown below) practice? What type of relationship normally described? (below, it is just producucing a series of integers)

    SELECT the level

    OF the double

    CONNECT BY LEVEL < = 10;

    T2. Use LEVEL with CONNECT BY in this way, a subversive use of the CONNECT IN knowledge is really intended to be used this way?

    any advice appreciated,

    Jim

    Hi, Jim,.

    for example

    SELECT employe_id, employee_name, level

    Employees

    CONNECT BY PRIOR employee_id = manager_id;

    Sometimes, CONNECT BY using hierarchical data, such as a tree.  In these cases, it may be useful to use the terns as "parent" and "child."  The query above is one of these cases.

    In more general terms, CONNECT BY returns the union (UNION ALL, specifically) of lines found by the START WITH clause (LEVEL = 1) and lines found by the clause CONNECT BY (LEVEL > 1).  If there is no START WITH clause, every row in the table will appear on LEVEL = 1.

    If there is no line on LEVEL = N, then Oracle research lines that meet the CONNECT BY clause, to search for the lines that are connected to each line level = N, for put the LEVEL N + 1.  If the CONNECT BY clause is set to TRUE for a given row, while the rank will appear on level N + 1 =.  Often (but not always) the CONNECT BY clause uses the PRIOR operator.  After PRIOR consent refers to something = N level.

    Q1. What is CONNECT BY LEVEL (for example as shown below) practice? What type of relationship normally described? (below, it is just producucing a series of integers)

    SELECT the level

    OF the double

    CONNECT BY LEVEL<>

    Since there is no START WITH clause, each line of the double table will be LEVEL = 1.

    The CONNECT BY clause means that CONNECT BY always means: If there is a line at = N, then it will be connected to any line that fills the CONNECT BY conditions.

    So that the lines will be added to the level = 2?  All the lines where condition 2<= 10="" is="" true,="" so="" every="" row="" in="" the="" dual="" table="" will="" be="" on="" level="">

    What lines will be added to the level = 3?  All the lines where condition 3<= 10="" is="" true,="" so="" every="" row="" in="" the="" dual="" table="" will="" be="" on="" level="">

    ...

    What lines will be added to the level = 10?  All the lines where the condition of 10<= 10="" is="" true,="" so="" every="" row="" in="" the="" dual="" table="" will="" be="" on="" level="10." 10="" is="" true,="" so="" every="" row="" in="" the="" dual="" table="" will="" be="" on="" level="">

    What lines will be added to the level = 11?  All the lines where condition 11<= 10="" is="" true,="" so="" no="" row="" in="" the="" dual="" table="" will="" be="" on="" level="">

    Since no rows are added to the LEVEL = 11, CONNECT BY query stop right there.

    Q2. Use LEVEL with CONNECT BY in this way, a subversive use of the CONNECT IN knowledge is really intended to be used this way?

    You can think of it as being subversive.  It was certainly not how planners and the deveopers at Oracle for CONNECT BY work in versions 2 to 8; you got an error if you tried in these versions.  It is also an exception to the rule that no line can be his own ancestor.
