left join problem?

I want left join two tables (a, b) where a.account = b.accountNumber number and this join must occur only for the specified account numbers. For this, my request is as follows.

Select a.PRIMARY_FIRST_NAME, a.PRIMARY_LAST_NAME, a.ACCOUNT_NUMBER, a.PRIMARY_SSN, a.ADDRESS_1, a.ADDRESS_2,
a.CITY, a.STATE, a.ZIP, b.phone_number, cust_account_details a b.status
Join phone_data b left
on
a.Account_Number = b.account_number
and
a.Account_Number in
('11 ', ' 22')


The above does not work correctly. the join occurs not only for the numbers in the range. What could be the problem?

Try this: -.

select a.PRIMARY_FIRST_NAME,a.PRIMARY_LAST_NAME,a.ACCOUNT_NUMBER,a.PRIMARY_SSN,a.ADDRESS_1,a.ADDRESS_2,
a.CITY,a.STATE,a.ZIP,b.phone_number,b.status from cust_account_details a
left join phone_data b
on
a.account_number=b.account_number
*where*
a.account_number in
('11','22')

Thank you.

  • LEFT JOIN DUPLICATION PROBLEM

    Hello

    I'm having a problem with the left join query, when I join table a two table based on column task1 I get duplicate in table1.task1, table1.price.

    Thank you.

    Note that your query uses an inner join. Your original question mentioned a join left, generally interpreted as meaning a left OUTER join.

    Anyway, according to Frank, you can use the BREAK command in SQL * Plus for the goal sought through formatting. You can also use an analytical function as Roger suggests. I think ROW_NUMBER() might do the trick, but we must be clear about the criteria for partitioning and ordering the results, for example

    WITH table1 AS (
  SELECT '001' AS task1
       , 100 AS price
  FROM   dual
), table2 AS (
  SELECT '001' AS task1
       , 'A' AS resources
       , 50 AS price
  FROM   dual
  UNION ALL
  SELECT '001' AS task1
       , 'B' AS resources
       , 250 AS price
  FROM   dual
)
SELECT DECODE(ROW_NUMBER() OVER (PARTITION BY t1.task1, t1.price ORDER BY t2.resources, t2.price),1,t1.task1) AS task1_alt
     , DECODE(ROW_NUMBER() OVER (PARTITION BY t1.task1, t1.price ORDER BY t2.resources, t2.price),1,t1.price) AS price_alt
     , t2.task1 AS task_with_resource
     , t2.resources
     , t2.price
FROM   table1 t1
INNER JOIN table2 t2
ON     t1.task1 = t2.task1
ORDER BY t1.task1, t1.price, t2.resources, t2.price;

  • LEFT JOIN increases the number of lines

    Hi guys,.

    I had a problem, my left join retrieves multiple values. I know he has only 252 in there that correspond to the place where

    condition. If I use the table in a left join with the same condition where my row count increases.

    -1176 lines

    Select count (erg_ID) of

    MySchema. T_STA_ERG sta_erg

    INNER JOIN T_MEN hoechst

    ON sta_erg. PARAMETER = hoechst. PARAMETER

    AND sta_erg. JAHR = 2014

    where sta_erg. MESSERG_KNG = 'A' AND sta_erg. MESSERG_ALPHA IN ('03 ") and sta_erg. NORM_MESS is null

    -252 lines

    Select distinct erg_ID myschema. T_STA_ERG sta_erg where sta_erg. MESSERG_KNG = 'A' AND sta_erg. MESSERG_ALPHA IN ('03 ") and sta_erg. NORM_MESS is null

    any clue´s how I can build in conditions in my join which would not increase the results of the line?

    Why not just an inner join then?

  • Outer join problem - revisited

    Hello
    I'm starting a new thread since my previous post was an inaccurate representation of the problem I have.

    I have data that looks like this.

    create table cour_off (offNum number, varchar2 (10) courseId, start_date date);
    create table activity (number oid, courseId varchar2 (10));
    create table ncr_course (course_oid number, incept_date date, expiry_date date);

    insert into cour_off values (1, 'MAT101', to_date (' 15 / 05/2012 ', ' DD/MM/YYYY'));
    Insert in activity values (10, 'MAT101');
    insert into ncr_course values (10, to_date (' 01 / 05/2012 ', ' DD/MM/YYYY'), to_date (' 10 / 05/2012 ', ' DD/MM/YYYY'));

    When I write the query using ANSI notation, the query works fine. 1 form is returned with a NULL value for the incept_date column.

    Select activity.courseId, ncr_course.incept_date
    of cour_off
    Join the activity on cour_off.courseId = activity.courseId
    activity.Oid left join ncr_course = ncr_course.course_oid
    and cour_off.start_date between ncr_course.incept_date
    and ncr_course.expiry_date
    where cour_off.offNum = 1

    However, when the style non ANSI query as shown below, no records are returned.

    Select activity.courseId, ncr_course.incept_date
    activity, cour_off, ncr_course
    where cour_off.offNum = 1
    and cour_off.courseId = activity.courseId
    and activity.oid = ncr_course.course_oid (+)
    and cour_off.start_date between ncr_course.incept_date and ncr_course.expiry_date

    I would like to know how I can resolve the application of style not ANSI so that the 1 record is returned.

    Thank you!

    Well, native Oracle outer join does not allow outside join two tables, to do something like:

    select courseId, ncr_course.incept_date
from (
      select activity.courseId,
             activity.oid,
             cour_off.start_date
        from cour_off, activity
        where cour_off.offNum = 1
          and cour_off.courseId = activity.courseId
     ), ncr_course
where oid = ncr_course.course_oid(+)
and start_date between ncr_course.incept_date(+) and ncr_course.expiry_date(+)

    I guess that the rewrite of the query with the optimizer is the origin of the problem.
    Say the 10053 trace? I don't have access to the database 11 GR 2 now to test.
    You can see if the advice of line NO_REWRITE or NO_QUERY_TRANSFORMATION gives the desired result.

  • Left join with three-table join query

    I am trying to create a query that left me speechless. Most of the query is simple enough, but I have a problem I do not know how to solve.

    Background:
    We have stock stored in i_action.

    We have the attributes available for each type of action. The attributes available for each action are described in shared_action_attribute. Each type of action can have three attributes or none at all.

    We have the values stored for the attributes in i_attribute_value.

    An example says:
    We have a transfer action (action_code B4). The action of B4 entry into i_action records the fact that the transfer took place and the date at which he spoke. The attributes available for a transfer action are the function code receiver, the receiving unit number and the reason of transfer code. These types of attributes available and their order are stored in shared_action_attribute. The actual values of the attributes for a specific action of transfer are stored in i_attribute_value.

    Now i_action and i_attribute_value can be connected directly in action_seq in i_action and ia_action_seq in i_attribute_value. A left join on these two tables provides results for all actions (including actions that have no attributes) and assign values (see Query 1 below).

    There are two questions. First of all, I want only the first two attributes. To specify the attributes of the first two, I also i_attribute_value a link to shared_action_attribute (which is where the order is stored). I can build a simple query (without the left join) which connects the three tables, but then shares without attributes would be excluded from my result (see Query 2 below).

    The second problem is that I'd actually a row returned for each action with first_attribute and second_attribute in the form of columns instead of two lines.

    The final query will be used to create a materialized view.

    Here are the tables and examples of what is stored in the:

    Hello

    You can use an alias for column (such as staff_seq) in the ORDER BY. Unfortunately, it's the only place where you can use it in the same query, where it was defined.
    You can use it anywhere in the super-requetes, however, so you can still work around this problem in assigning the aliases in a subquery and GROUP BY (or other) in a Super query, like this:

    WITH   ungrouped_data      AS

                               AND sactatt_sat_type = 'SS'
                                 THEN VALUE

      LEFT JOIN i_attribute_value iav

    No, you don't have to if you add the restriction to the join instead of a filter condition condition:

  • HP Envy 17 Notebook PC TS left hinge problem

    Left hinge on my HP Envy TS 17 Notebook PC pushes the lower lid of my laptop open whenever I open and close my laptop. My desire is quite recent and it is still under the one year warranty.

    Hello

    Yes.  MY problem is solved.  Company and I got the replacement unit successfully.

    Note: If you have a lot of software installed, especially of VMs on your current laptop, so my personal advice would be to get the repaired unit, I came across the problem to reactivate the license think little software, I do several facilities and refuse activation.   However after talking to the licensing issue has been resolved, but it consumes a lot of time.

    However, if the activation of the license is not a problem for you then unit replacement is better.

    Concerning

    PS. but in the new laptop also, I always get a little tic noice when I open and close the laptop from the left hinge.   That is why I it opens very slowly.  I have just pray and hope that it does not break.  because I get 2nd replacement.

  • LEFT JOIN question

    Hello

    Here's 2 queries. First one help for the joints and the second query uses a join ancient. The first works very well and I tried to write the 2nd one to work exactly like the first. I don't know where to put the sub condition sysdate in 2nd query such that there operator.

      AND trunc(SYSDATE) BETWEEN hapf.effective_start_date(+) AND
       hapf.effective_end_date(+)

    1.

    SELECT papf.full_name,
       hapf.name position_name
  FROM per_people_x       papf,
       per_assignments_x  pax,
       hr_all_positions_f hapf
 WHERE papf.person_id = pax.person_id
       AND pax.position_id = hapf.position_id(+)
       AND trunc(SYSDATE) BETWEEN hapf.effective_start_date(+) AND
       hapf.effective_end_date(+)

    2.

    SELECT papf.full_name,

       per_assignments_x pax
  LEFT JOIN hr_all_positions_f hapf
    ON (pax.position_id = hapf.position_id)

  • LEFT JOIN and performance

    Hi guys,.

    I inherited a previous devloper the query below. T_MAXVALUES has 100,000 rows and T_STA_ERG about 1 m.

    The performance is so bad, it works for 5 hours now and I have nothing so I can´t say much about the data of test or how it should look.

    It works on Oracle 11 g and I can´t get my head around all JOIN clauses and the ultimate goal but sense that there could be a better way

    to achieve what is tried below. All of you guru´s able to immediately spot the big failures?

    SELECT DISTINCT T1. PARAMETER, T1. ZERL_MATRIX, T1. MONTHS, T1. ADDITIONAL_CRI,

    DECODE (H2. MRL, NULL, (DECODE (H1. MRL, NULL, (DECODE (H3. MRL, NULL, (DECODE (H4. MRL, NULL, NULL, 'R')), 'R')), M1. MRL)), H2. MRL)

    OF T_STA_ERG T1

    LEFT JOIN (SELECT PARAMETER, ZERL_MATRIX_2, MRL

    OF T_MAXVALUES, WHERE ZERL_MATRIX_1 IS NULL) H1

    ON T1. PARAMETER = H1. PARAMETER

    AND substr (T1. ZERL_MATRIX, 4, 3) = H1. ZERL_MATRIX_2

    LEFT JOIN (SELECT PARAMETER, ZERL_MATRIX_1, ZERL_MATRIX_2, MRL

    OF T_MAXVALUES

    WHERE ZERL_MATRIX_1 IS NOT NULL) H2

    ON T1. PARAMETER = H2. PARAMETER

    AND substr (T1. ZERL_MATRIX, 1, 3) = H2. ZERL_MATRIX_1

    AND substr (T1. ZERL_MATRIX, 4, 3) = H2. ZERL_MATRIX_2

    LEFT JOIN (SELECT PARAMETER, ZERL_MATRIX_2, MRL

    OF T_MAXVALUES

    WHERE ZERL_MATRIX_1 IS NULL) H3

    ON T1. PARAMETER = H3. PARAMETER

    LEFT JOIN T_MAXVALUES H4

    ON substr (T1. ZERL_MATRIX, 1, 3) = H4. ZERL_MATRIX_1

    The idea is to get maxvalues lines that at least match the lines of t. The game minimum is the game of columns of the parameter (type 3), or matches the matrix 1 (type 4).

    If you get all possible matches, and you will then take the MRLS of the best match: better if the parameter, matrix1 and matrix2 all game, then if parameter and matrix2 match, etc.

    What I have not included here are a test for null matrix1. If a match where parameter and matrix2 match, but there's a matrix1 value that does not match the value in T matrix1, will have to be thrown out, then just add this additional condition in the CASE statement.

    Untested of course:

    Select T1. PARAMETER, T1. ZERL_MATRIX, T1. MONTHS, T1. ADDITIONAL_CRI, Max (MRL) keep dense_rank of first order by type)

    Of

    (SELECT T1. PARAMETER, T1. ZERL_MATRIX, T1. MONTHS, T1. ADDITIONAL_CRI,

    -case when T1. PARAMETER = H.PARAMETER and substr (T1. ZERL_MATRIX, 1, 3) = H2. ZERL_MATRIX_1 AND substr (T1. ZERL_MATRIX, 4, 3) = H2. ZERL_MATRIX_2 then 1

    When T1. PARAMETER = H.PARAMETER and substr (T1. ZERL_MATRIX, 4, 3) = H1. ZERL_MATRIX_2 then 2

    When T1. PARAMETER = H.PARAMETER then 3

    When substr (T1. ZERL_MATRIX, 1, 3) = H.ZERL_MATRIX_1 then 4

    end match_type, h.mrl

    OF T_STA_ERG T1

    LEFT JOIN T_MAXVALUES h on (T1. PARAMETER = H.PARAMETER or substr (T1. (ZERL_MATRIX, 1, 3) = H.ZERL_MATRIX_1)

    )

    Group T1. PARAMETER, T1. ZERL_MATRIX, T1. MONTHS, T1. ADDITIONAL_CRI;

  • Clarification on NULL or behavior LEFT JOIN behavior

    Good day ladies------Gentlemen\ gurus-Experts-and Al:

    Just when I thought I got my mind wrapped around the notion of NULL value, as defined by Oracle, I met what follows below.  Basically, what you are watching is how our employees of the human resources tables are set up (for the most part).  We have the employees, employee contracts table and the tables of positions.  When I want to make a list of active staff, I always use the filter end date, you will see below in the Super request, essentially looking for staff who do not have a contract AND a position end date entered in the DB.  It works like a charm.  However, today, I noticed an official on the list, who has never had a position is entered in the comic book, and he had an 'open' contract  In my example below, why would "Hal Jordan" appear on the active staff list?  Yes, he spends the first part of my predicate (contract_end is null), but it does not work (at least by my understanding) past the second part of the predicate which is position_end has the value NULL because there not even a record is entered in the comics!  Why would he appear?  Is it because of the LEFT JOIN or a NULL rule type, I'm not aware of?  Thanks for your help!

    It's the outer join.

    When you say

    Employees are

    LEFT JOIN emp_positions ON ep.emp_id = es.emp_id ep

    then, at the time when the WHERE clause is evaluated, the result set contains at least 1 row for each line of employees.  If there is no line in emp_postitions that meet the join condition, then all the columns that should be provided by the emp_positions table will be NULL. This is precisely what concerns the outer join.

    Think about it for a minute.  NULL means the absence of any value.  Is there is no corresponding row in the emp_positions table, then there is no value for emp_position.position_end.  If so doesn't; "have a value, then, by definition, it is NULL.

    It if were not NULL, then this would mean that it had a value.  Would what value?  Why the request would give him one value rather than another?

    Thanks for the display of the data of the sample; It's always useful!

  • Double left join creates a unwanted loop...

    I have therefore two paintings, I need to extract the counts of "tickets".

    I want to have the date given match then I use a 'connect by level' so that the same dates without data will have records in the result set.

    There are two tables I want to join on this "timeline" when I join each of them that individually, it works but when I join together that there is an order of operations issue I'm not sure how to move.

    ORIGINAL DATA:

    TABLE SMINCREQ:

    OPEN_DATE NUMBER
    JANUARY 12, 2015IM392039
    JANUARY 12, 2015IM399495
    JANUARY 12, 2015RM394950
    JANUARY 13, 2015IM394958
    JANUARY 13, 2015
    		RM394958

    TABLE SMINTERACTIONS:

    OPEN_DATE INCIDENT_ID
    JANUARY 12, 2015SD394858
    JANUARY 12, 2015SD399495
    JANUARY 12, 2015SD394950
    JANUARY 13, 2015SD394958
    JANUARY 13, 2015
    		SD394958

    THE QUERY:

    SELECT to_char(DAYS_,'DD-MON-YYYY'),
      
      sum(decode(INSTR(SMINCREQ."NUMBER",'IM'),'1','1',0)) "INCIDENT",
      sum(decode(INSTR(SMINCREQ."NUMBER",'RM'),'1','1',0)) "REQUEST"
     --sum(decode(INSTR(SMINTERACTIONS.INCIDENT_ID,'SD'),'1','1',0)) "INTERACTION"  
      FROM
  ( SELECT (TRUNC(to_date(SYSDATE-ROWNUM),'DD')) DAYS_ FROM DUAL
CONNECT BY LEVEL <= (SELECT 14 FROM DUAL)
  ) THE_TIMELINE
    LEFT OUTER JOIN SMINCREQ ON  (to_char(DAYS_,'DD-MON-YYYY')=to_char(SMINCREQ.OPEN_TIME,'DD-MON-YYYY')  and (OPEN_GROUP like '%HELP%'))
    --LEFT OUTER JOIN SMINTERACTIONS on (to_char(DAYS_,'DD-MON-YYYY')=to_char(SMINTERACTIONS.OPEN_TIME,'DD-MON-YYYY')  and PRIMARY_ASSIGNMENT_GROUP like '%HELP%')
    GROUP BY to_char(DAYS_,'DD-MON-YYYY') ORDER BY to_char(DAYS_,'DD-MON-YYYY')
  ;

    When I run the present and just get the number of SMINCREQ is

    DATEINCIDENTSREQUEST
    JANUARY 12, 20151034
    JANUARY 13, 20155910

    When I run the query for SMINTERACTIONS I get

    DATEINTERACTION
    JANUARY 12, 201555
    JANUARY 13, 201550

    When I try to run the two left joins them together I get:

    DATEINCIDENTSAPPLICATIONSINTERACTIONS
    JANUARY 12, 201556652205885
    JANUARY 13, 201529505003450

    I know that what is happening is a loop where the date is is developed in a relationship 1 to many through the joints and then the GROUP is not the case until the end.

    What I want to achieve is:

    DATEINCIDENTSREQIESTINTERACTION
    JANUARY 12, 2015103455
    JANUARY 13, 2015591050

    Thanks for the tips

    I decided to go this route that will just join the new data (INTERACTIONS) of INCIDENTS already implemented and APPLICATIONS:

    SELECT NULL LINK,DAYS,INCIDENT,"REQUEST",sum(decode(INSTR(SMINTERACTIONS.INCIDENT_ID,'SD'),'1','1',0)) "INTERACTION" from(

SELECT to_char(DAYS_,'DD-MON-YYYY') DAYS,sum(decode(INSTR(SMINCREQ."NUMBER",'IM'),'1','1',0)) "INCIDENT",
      sum(decode(INSTR(SMINCREQ."NUMBER",'RM'),'1','1',0)) "REQUEST"
      FROM
  ( SELECT (TRUNC(to_date(SYSDATE-ROWNUM),'DD')) DAYS_ FROM DUAL
 CONNECT BY LEVEL <= (SELECT 14 FROM DUAL)
  ) THE_TIMELINE
    LEFT OUTER JOIN SMINCREQ ON  (to_char(DAYS_,'DD-MON-YYYY')=to_char(SMINCREQ.OPEN_TIME,'DD-MON-YYYY')  and (OPEN_GROUP like '%HELP CENTER%')
)

    GROUP BY to_char(DAYS_,'DD-MON-YYYY') ORDER BY to_char(DAYS_,'DD-MON-YYYY')
) LEFT JOIN SMINTERACTIONS on (DAYS=to_char(OPEN_TIME,'DD-MON-YYYY') and (PRIMARY_ASSIGNMENT_GROUP like '%HELP CENTER%'))
GROUP BY DAYS,INCIDENT,"REQUEST" order by DAYS ASC;

    Thanks for all the entries...

  • Left join

    Hello world

    Im trying to create the query that displays the values that are not available in the other table.

    Scenario:

    I have two tables, the material and materialfolder. I want to display documents that are not available in materialfolder.

    Here's my query

    SELECT m.material_id

    The result does not show the correct values. Don't know what my error here...

    Hoping that someone could help me.

    Thank you.

    Hello

    If you just want to know the values that are not available in materialfolder, use a NOT EXISTS condition:

    SELECT m.material_id

    m.MATERIAL_TYPE_ID

    $m.name

    m.created

    MATERIAL m

    If NOT EXISTS (select null from materialfolder mf

    where m.material_id = mf.material_id

    )

    AND m.CREATED > = TO_DATE('01/01/2011', 'dd/mm/yyyy') AND m.CREATED< to_date('01/01/2014',="">
