• 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,

• 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;

• 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?

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

  TABLE SMINTERACTIONS:

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

  DATE	INCIDENTS	REQUEST
  JANUARY 12, 2015	103	4
  JANUARY 13, 2015	59	10

  When I run the query for SMINTERACTIONS I get

  DATE	INTERACTION
  JANUARY 12, 2015	55
  JANUARY 13, 2015	50

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

  DATE	INCIDENTS	APPLICATIONS	INTERACTIONS
  JANUARY 12, 2015	5665	220	5885
  JANUARY 13, 2015	2950	500	3450

  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:

  DATE	INCIDENTS	REQIEST	INTERACTION
  JANUARY 12, 2015	103	4	55
  JANUARY 13, 2015	59	10	50

  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 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.

  Table1. Task1	Table1. Price	table2. Task1	table2. Resource	table2. Price
  001	100	001	A	50
  001	100	001	B	250

  How can I make a request to get a result as below.

  Table1. Task1	Table1. Price	table2.Task2	table2. Resource	table2. Price
  001	100	001	A	50
  		001	B	250

  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

• Interesting behavior of left join

  We will create 3 tables as follows:
  

  
  

  CREATE TABLE "A1" ()"A1_ID" NUMBER ENABLE NON NULL,CONSTRAINT "A1_PK" SELECT the PRIMARY KEY ('A1_ID') );

  CREATE TABLE "A2" ()"A2_ID" NUMBER ENABLE NON NULL,CONSTRAINT "A2_PK" SELECT the PRIMARY KEY ('A2_ID'));

  Insert into A1 values (1);

  Insert into A1 values (2);

  Insert into A1 values (3);

  Insert 4 A1;

  Insert into A1 values (5);

  Insert into A1 values (6);

  Insert into A2 values (1);

  insert into values A12 (1,1,1);

  Tables a1 and A2 are just simple tables with primary keys and A12 table contains many-to-many relationship between them.

  When I run the query below,

  SELECT * A1 A1 A12 A12 LEFT JOIN ON a1.a1_id = a12.a1_id A2 LEFT JOIN A2 ON a2.a2_id = a12.a2_id WHERE a2.a2_id IS NULL;

  I get the following results, as I predicted:

  A1_ID A12_ID A1_ID A2_ID A2_ID

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

  6

  5

  4

  3

  2

  However when I run the second query below (where I select only the a1 id column instead of "*")

  SELECT a1.a1_id A1 A1 A12 A12 LEFT JOIN ON a1.a1_id = a12.a1_id A2 LEFT JOIN A2 ON a2.a2_id = a12.a2_id WHERE a2.a2_id IS NULL;

  
  

  I get nothing, no lines have been selected. When I look at the plan of the second query I see a predicate to filter such as "'NULL IS NOT NULL". " I guess that this does not return results. Is this a bug, or y at - it a satisfactory explanation for this behavior?

  Step 1 - check the execution plans.

• Left join of the two tables and multiple values into a single value separated by commas

  Hello

  I have following tables with their structures and their data as below.

  These two tables have left join as

  BETMASTER. CUREPRESS = substr (BETINFO. CURRENTPRESS, 1, 3)

  now I want to have the data in the two tables with fields Curepress, Lastpcirim, typeidcontainer.

  Also something like

  Make a group of typeidcontainer if this value is greater than 1 by press separated the values of semicolon (;)

  So, for example above, we should be given as

  A24 PMC 15; PENSKY-MARTENS

  A25 15 PMC

  A26 15 PMC

  A27 16 (NULL)

  A28 16 (NULL)

  A30 15 (NULL)

  A31 16 (NULL)

  A32 16 BFC2-V; V BFC3

  A33 16 (NULL)

  A34 16 (NULL)

  How could do?

  My current request is as

  Select distinct Curepress, lastpcirim, typeidcontainer

  BETMASTER STD left join INF BETINFO

  on the trim (STD. CUREPRESS) = substr (trim (INF. CURRENTPRESS), 1, 3)

  but I am unable to get the values separated by commas.

  Any help would be appreciated.

  Thank you

  Hi, Mahesh,

  If you want to only 1 row of output for each distinct combination of currentpress and lastpcirim?  This sounds like a job for GROUP BY.

  And you want the row to contain a list of all different typidcontainers-delimited?  This sounds like a job for the aggregate LISTAGG function.

  WITH joined_data AS

  (

  SELECT DISTINCT

  MST.curepress, mst.lastpcirim, inf.typeidcontainer

  OF betmaster STD

  LEFT JOIN betinfo ON TRIM (mst.curepress) inf = SUBSTR (TRIM (inf.currentpress)

  1

  3

  )

  )

  SELECT curepress, lastpcirim

  LISTAGG (typeidcontainer, ',')

  THE Group (ORDER BY typeidcontainer) AS container_list

  OF joined_data

  Curepress GROUP, lastpcirim

  ;

  Unfortunately, you can't say LISTAGG (DISTINCT ...), so you should always get the separate containers how you already are.  (Note that the subquery is just what you posted).

  Thanks for posting the CREATE TABLE and INSERT statements; It is very useful.  Don't forget to tell what version of Oracle you are using.  LISTAGG was new in Oracle 11.2.

  Why not add CHECK constraints (and perhaps triggers) to your tables, so that curepress and currentpress are not stored with the head or trailing spaces?  Then you wouldn't need to use the PAD in queries like this, and your code would be simpler and more effective.

  And for this reason I am come so many duplicates and do not correct results for JUNEBUG, WAVY, DRUMTYPE1, and STARTDATE field.
  
  I need some advice as how can I do so that I get the correct results without duplicates for the PRIMARY KEY.
  
  Thank you
  
  Mahesh

  It would have been easier to answer if you gave us your example query that gives incorrect results - which both show us what you are doing and give us a starting point.
  Insert instructions for data, rather than only the data would have helped too, making it more quick to test this point.
  You do not show what you have done with your two outer join criteria, but I think you need to list TIREMASTERPROCESS_TEMP in your query twice, with alias names. Here's what I did:

  select a.BUILDINGSIZE, a.GTCODE, b.PROCESSNO ,  c1.FIELDNAME, c1.DATACHR, C2.FIELDNAME, C2.DATACHR
  , CASE WHEN c1.FIELDNAME='BTDrumNo1' then c1.DATACHR end drumtype1
  , CASE WHEN (trim(c2.DATACHR) = '1' and trim(c2.FIELDNAME) = 'No-of-Nch') THEN 'YES' ELSE 'NO' END CHAFER
  , case when c1.FIELDNAME='Wavy' AND c1.DATACHR='Use' THEN 'YES'
         when c1.FIELDNAME='Wavy' then 'NO' else null end wavy
  from BUILDINGSCHEDULEMASTER        A
  join materialcode b on a.GTCODE=b.UPPERMATERIALCODE
  left outer join TIREMASTERPROCESS_TEMP c1
     ON trim(b.UPPERMATERIALCODE)||'-'||trim(b.PROCESSNO) = trim(c1.PRODUCTIONCODE)||'-'||trim(c1.REVISIONNO)
  left outer join TIREMASTERPROCESS_TEMP c2
     ON substr(trim(b.UPPERMATERIALCODE),1,2)||'-'||trim(b.PROCESSNO) = trim(c2.PRODUCTIONCODE)||'-'||trim(c2.REVISIONNO)
  

  C1 is an alias for the TIREMASTERPROCESS_TEMP line which is necessary for drumtype1 and wavy, c2 is an alias for the TIREMASTERPROCESS_TEMP line required for JuneBug. There was some minor errors in your calculations of field I tried to correct.

  The results are:

  BUILD GTCO PRO FIELDNAME    DATACHR    FIELDNAME    DATACHR    DRUMTYPE1  CHA WAV
  ----- ---- --- ------------ ---------- ------------ ---------- ---------- --- ---

  When I tried using a General left join she gave much more duplicate rows.
  I have 100 lines in curepress, then I would have only 100 lines in the final result but I get my as 233 lines output, this may be due to CUREPRESSMASTER. CURINGGROUP = NAMINGMASTER. Certificate3 this condition.
  
  Please suggest me some queries.

  This may be due to CUREPRESSMASTER. CURINGGROUP = NAMINGMASTER. Certificate3 this condition.

  Email from Dan is not included, because his "wrk1" email does not stop it school.edu
  E-mail Mary is not included, because his 'wrk1' email is not active.
  However, I need to come back with their numbers of name registration and employee.

  Hello

  WHERE is the filtering actually record the selection.

  In your case, you might want to include in your LEFT OUTER JOIN ON conditions:

  SELECT p.employee, p.recordnum, p.lastname, p.firstname
       , e.emailaddress, e.emailactive, e.emailtype
    FROM    thepeople p
         LEFT JOIN
            theemails e
         ON     p.employee = e.employee
            AND e.emailactive = 1
            AND e.emailtype = 'WRK1'
            AND e.emailaddress LIKE '%school.edu';
  

  If you put them in your JOIN conditions actually join Chronogram of table theemails that adapt to the conditions of membership.
  As you use LEFT [OUTER] JOIN unmatched chronogram thepeople table will be displayed even when the theemail table column appears with a NULL value in the output files

  I hope that I was able to unlock your brain. :-)

  Kind regards.

  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.
