  • How to write this query in the hierarchy

    Hi gurus,

    Really need your help on this query.  Thank you very much in advance.

    SELECT
  t1.key as root_key ,
(SELECT
      t2.unit_id AS unit_id 
      level-1 AS level ,
      t2.name,
      t2.creator
    FROM
      tab t2
      START WITH t2.unit_id       =   t1.unit_id            -----check each node as root
      CONNECT BY prior t2.unit_id = t2.parent_unit_id

  )
   t1.name as parent_unit_name
FROM
  tab t1

    I'll write a query of the hierarchy as above, and that EACH line (node, totally more than 10200) is checked as root node to see how many sheets are accessible for her... It must be implemented in a single query.

    I know inline query should NOT return multiple rows or multiple columns, but the inline elements are necessary and can certainly be made in a correct solution.

  • How to write this query?

    Hi people,

    I need to get a query in which a set of records, I get ONLY those which previous registry has a field with a value to this topic. Other values, the field can contain are not necessary.

    I know that sounds easy but... I can't get it.

    So, for Oracle 10 g 2... Here's my query:

    SELECT a.person_id, a.person_status, a.message_id, a.order_id

    OF t_HR one

    WHERE a.person_status = "rejected".

    AND a.id >

    (SELECT max (b.id)

    OF t_HR b

    WHERE b.person_id = a.person_id

    and b.order_id = a.order_id

    AND b.person_status! "revised =".

    B.ID AND < a.id)

    ORDER BY desc a.id

    Let me explain:

    1 - HR table is a table of people. These people has serveral STATUS.

    2 - ID is a sequential (each www.voyages-sncf.com has a different identification number).

    3 - the application must get THAT all people "rejected".

    4. - However, (subquery) I need ONLY those that previous register (the second register) holds a status of "OK". If the person holds a "revised" status he's not, he should be the next register (the third)

    5.-L' ORDER ID DESC, so is the first register must have a STATUS = "rejected" and the second a 'OK '.  IF the second register = "revised", then the third register must be 'OK '. And I need this query.

    HOW DO?

    My problem: the subquery gives you previous register of the same guy, but... it does not give you the value of the State, I need, which is 'OK '.

    I tried to add to the subquery...

    SELECT max (b.id)

    OF mod_human_resource b

    WHERE b.person_id = a.person_id

    and b.order_id = a.order_id

    AND b.person_status = 'OK '.

    AND b.id < a.id

    ... but if I have 5 records of that person, the first is "rejected", the second is "accepted", the third is 'new' and the fourth is 'OK'... the subquery gives you the 4th register and which is not correct for me, it must be only the second one (prior to the first State registry).

    I need to be a query, because I need to use it on a MERGER for a DWH.

    If there is another way (function, or even a procedure) to make the MERGER rather than with a request, which would be ok too. I am poor DWH knowledge.

    Thanks in advance.

    Hello

    So, you need to know if a line is the 'first' line, and you should also know what is the 'next' status, (even the 'first' and 'next' are already defined).  This sounds like a job for analytical functions.  ROW_NUMBER can tell you if a line is first or not, and LEAD can tell you what a value on the next row.

    Since you post CREATE TABLE and INSERT statements for your own table, I'll use the table scott.emp to illustrate.

    Consider these data from scott.emp:

    SELECT DeptNo

    ename

    work

    FROM scott.emp

    ORDER BY deptno

    ename DESC

    ;

    Output:

    DEPTNO ENAME JOB

    ---------- ---------- ---------

    10 MILLER CLERK

    PRESIDENT OF KING 10

    MANAGER 10 CLARK

    20 SMITH CLERK

    ANALYST SCOTT 20

    20 JONES MANAGER

    20 FORD ANALYST

    20 ADAMS CLERK

    30 WARD SALESMAN

    SELLER OF 30 TURNER

    30 MARTIN SALESMAN

    30 JAMES CLERK

    MANAGER BLAKE 30

    30 ALLEN SALESMAN

    Now, let's say we want only who know the departments where the forefront (in order descending ename) a job = 'CLERK', and the following line (also in descending by ename order) = "ANALYST" job, and we want to know the ename of the first row.  In other words, the correct output is:

    DEPTNO ENAME

    ---------- ----------

    20 SMITH

    Note that deptno = 10 is not included, even if the first task is to "CLERK." that was because the second job in deptno = 10 is the "PRESIDENT", not "ANALYST."

    Here's a way to get these results:

    WITH got_analytics AS

    (

    SELECT ename, deptno, job

    ROW_NUMBER () OVER (PARTITION BY deptno

    ORDER BY ename DESC

    ) AS r_num

    LEAD (employment) OVER (PARTITION BY deptno

    ORDER BY ename DESC

    ) AS next_job

    FROM scott.emp

    )

    SELECT deptno, ename

    OF got_analytics

    WHERE r_num = 1

    AND job = 'CLERK '.

    AND next_job = 'ANALYST '.

    ;

    I hope that answers your question.

    If this isn't the case, then, as Dan (and the FAQ forum) said, post CREATE TABLE and INSERT statements for some sample data and the exact results you want from these data.

    Post your query, based on the one I have posted more top and ponit out where he gets results.

    Always say what version of Oracle you are using (for example, 11.2.0.2.0).

    Table1 a record 3Million and table 2 has 1 million records.

    I used gather stats before you run this query and 'Full' trick, even in this case, he is running for 45 minutes.

    Please suggest the best solution to optimize this query.

    Thanks in advance.

    Remove the tips.

    No need for the separate.

    Get the diff by ceil (abs(t2.m_date-t1.m_date)) and the filter for that where value_diff<>

    Assing the statement ".. MATCHED" lately in the update clause.

    Maybe give exactly to your needs with a small example may be the query may be getting more simplified or not what you want it to do.

  • How to solve this query in database using sqlite phone gap

    am facing a problem in recent days. The problem is database. In fact, I create the mane database 'casepad '. Then I created a table because the database 'table of cases' have (ID, name, date). Now I insert the value on this table. When inserting I also create a name ("casename") .mean table if I insert the value of the case table (1, 'AB', 2/13). Then I create table AB. Now I need to get the value of the case table (I am) but I need to count the number of items in another table (AB). Here, I had to try it.

    function onDeviceReady() {

    db = window.openDatabase("Casepad", "1.0", "Casepad", 200000);

db.transaction(getallTableData, errorCB);

}

function insertData() {

}

function createTable(tx) {

    tx.executeSql('INSERT OR IGNORE INTO CaseTable(CaseName,CaseDate,TextArea) VALUES ("' + $('.caseName_h').val() + '", "' + $('.caseDate_h').val() + '","' + $('.caseTextArea_h').val() + '")');

}

}

//select all from SoccerPlayer
function getallTableData(tx) {

}

function querySuccess(tx, result) {
    var len = result.rows.length;
    var t;
    $('#folderData').empty();
    for (var i = 0; i < len; i++) {

        $('#folderData').append(
                '

}

    Instend of show the value of 'i' in the view list, I need to show how many element in the table. I have to call synchronize because I call a query that counts the number of elements to 'result.rows.item (i). CaseName"this item... ?

    Hello

    If I understand correctly, you are looking for a SQL statement that you will get the count for the number of items in the table AB? If so, this can be useful:

    Create an index as above, but it does not seem to be used to explain the plan for the part of XML query.

    and a lot of time, I also get this error but I cannot now re - produce for some reason.

    I thought that its because I can't index after branch out according to s_ID

    SQL Error: ORA-29879: cannot create multiple domain indexes on a column list using same indextype
29879. 00000 -  "cannot create multiple domain indexes on a column list using same indextype"
*Cause:    An attempt was made to define multiple domain indexes on the same
           column list using identical indextypes.
*Action:   Check to see if a different indextype can be used or if the index
           can be defined on another column list.

    and this index below seems to have choice as shown explain plan.

    Why can't I see the index above in the plan to explain it?

      CREATE INDEX "OE"."XMLTST_INDX01" ON "OE"."XMLTST" ("XMLDATA") 
   INDEXTYPE IS "XDB"."XMLINDEX"  PARAMETERS ('paths (include (/SWs/SW/@s_ID))');

    However, it is still the loop nest join when the join of two tables after the XML in the process... Is it possible to tell Oracle to a join index or some kind of faster join after the XML select part.

    My real case got way as many lines to make the join of X - Y and it may be nice to have an index to quickly reach?

    When do some small tests, the clause will eventually cause oracle core dump. It should not happen even it is a virtual machine with 3G of memory max and the max_memory_target = 800 M as all my data are not not even 50 M.

    We are the team of analysts and Dev team suggest that is a little too much time to contact Oracle Support and I finally create 3 global temporary table with commit preserve rows and operate with performance much better.

  • How to run this query correctly?

    Hi Sir,

    I use a query that I converted from sql to oracle but in error.

    Error (4.3): PLS-00428: an INTO clause in this SELECT statement

    Here's my query:

    SELECT distinct Code pa.id, pa. Empcode Emp_ID, E.Emp_FirstName | ' ' || E.Emp_LastName Emp_Name, pa. Work Date1 date, pa. InPunch In_Punch, pa. OutPunch Out_Punch, pa.approve, ls. Leave_Status_text StatusText, NVL (pt.punchtype, 'day') JOIN employee E ON PunchForApproval pa e.Emp_ID punchtype is pa. Empcode LEFT JOIN Leave_status ls TO ls. Leave_Status_id = pa.approve LEFT JOIN punchtype pt ON pt.id = pa. STATUS
    WHERE E.Emp_ID IN (SELECT Emp_id FROM employee) ORDER BY pa.id DESC;

    Thank you

    Hello
    You run this in a PL/SQL procedure? If so, what the procedure called the request?

    Also, did you see the error even if you add a space to the request here.

    WHERE E.Emp_ID IN (SELECT Emp_id FROM employee) ORDER BY pa.id DESC;

    -implement-

    WHERE E.Emp_ID IN (SELECT Emp_id FROM employee) ORDER BY pa.id DESC;

    Kind regards

  • How to use this query in oracle?

    Hi Sir,

    I use a SQL query that is

    declare @date date ='2012-10-25', @date1 varchar (5)
    Set @date1 = DATEPART (W, @date)
    impression @date1

    that its value means day 25 oct 5 back Thursday it is checking and counting from Sunday in this week so the result is 5 next.

    and storing in @date1

    the same result I want in oracle.

    Thank you

    Try this...

    /* Formatted on 10/5/2012 10:22:34 AM (QP5 v5.163.1008.3004) */
SELECT TO_CHAR (TO_DATE ('2012-10-25', 'yyyy-mm-dd'), 'D') FROM DUAL;

    gives

  • How to create this query

    Hello
    I have a query like
    Greatest ((a-b), 0) twice;
    I want to add in it so a - b is lower, then set to zero then the value of 'a' must be printed.


    concerning

    Try using DECODE

    select decode(sign(1-2),-1,1,2) from dual
/

DECODE(SIGN(1-2),-1,1,2)
------------------------
                       1
