• The join SQL query help

  I'm just having a bit of troubel get a correct join query - I thought it was an Inner Join, but I don't get the results I expect.

  My table structure is:

  Table: lodges

  LodgeID (PK)

  Lodge

  etc.

  Table: implemented application

  NominationID (PK)

  Category

  LodgeID

  Year

  So I try to use this structure to replicate this page:

  http://www.safariawards.com/nominees12/

  That is to say a list of boxes for each category, they are appointed on.

  The query I've tried looks like this:

  SELECT appointments. LodgeID, lodges. Lodge, applications. NominationID, applications. Lodges INNER JOIN applications category IT lodges. LodgeID = nominated. NominationID WHERE category = "Best property of Safari in southern Africa" ORDER BY Lodge

  But this product:

  http://www.safariawards.com/nominees12/southernafrica.php

  Its the right number of results, but not the list on the right of the boxes - for example British Airwways is not LodgeID 786

  If anyone could help with the SQL right for what would be well appreciated.

  That you join on the wrong column. Try this:

  SELECT appointments. LodgeID, lodges. Lodge, applications. NominationID, applications. Lodges INNER JOIN applications category IT lodges. LodgeID = nominated. LodgeID WHERE category = "Best property of Safari in southern Africa" ORDER BY Lodge

  Thank you Frank, Sundar and Sean. I had less than 3 to work. Two questions. My table of DEVICES has 31936 records.
  1. the first one returned 30207, 31936 records 2nd and 3rd a 30348. Since the 2nd result resembles what I expected, the 1st and 3rd one seem to miss some records. For troubleshooting, I tried to limit the query to a few devices, but do not understand why the difference. Any suggestions?

  The 2nd query not check for type_contact = 'ROUT', it is not surprising that it returns more rows.
  The request of 3rd fact actually an inner join. The "WHERE c.rnum = 1" condition is applied after the join, so he rejects all rows that have been added due to the outer join (which is where all the columns of c are NULL). You probably meant to say:

  LEFT OUTER JOIN got_rnum c ON  d.DEVICE_ID     = c.CONTACT_ID
                             AND c.rnum          = 1; 
  

  without a WHERE clause.

  2. are there advantages in terms of efficiency. 2nd one does not seem to run faster, so I think it's the best. Any comments?

  SELECT a.DEVICE_ID, b.LASTNAME,b.FIRSTNAME,b.PRIORITY
  FROM DEVICE a, CONTACT b
  where
  a.DEVICE_ID=b.CONTACT_ID(+) and
  b.CONTACT_TYPE = 'ROUT' and
  b.PRIORITY = (select min(b1.PRIORITY ) from CONTACT b1 where b1.CONTACT_ID = b.CONTACT_ID);
  
  30207 rows selected (10.12 seconds)
  
  SELECT DEVICE_ID, LASTNAME, PRIORITY
  FROM (
  SELECT a.DEVICE_ID, b.LASTNAME, b.PRIORITY, ROW_NUMBER() OVER (PARTITION BY a.DEVICE_ID ORDER BY b.PRIORITY) row_num
  from DEVICE a, CONTACT b
  where a.DEVICE_ID=b.CONTACT_ID(+))
  WHERE row_num = 1;
  
  31936 rows selected (6.68 seconds)
  
  WITH got_rnum AS (
  SELECT LASTNAME, FIRSTNAME, PRIORITY, CONTACT_TYPE, CONTACT_ID,
  ROW_NUMBER () OVER ( PARTITION BY  CONTACT_ID ORDER BY priority) AS rnum
  FROM contact
  where CONTACT_TYPE = 'ROUT'
  )
  
  SELECT d.DEVICE_ID, c.LASTNAME, c.FIRSTNAME, c.PRIORITY
  FROM device d
  JOIN got_rnum c ON d.DEVICE_ID     = c.CONTACT_ID(+)
  WHERE c.rnum = 1; 
  
  30348 rows selected (9.07 seconds)
  

  This calendar is not very accurate. One that you run first is likely to be slower, because the data are less likely to be stored in the memory cache.

  The 2nd query has only 3 columns in the result set. Which probably doesn't change the speed a lot, but you should fix it anyway.

• Need help with joins Oracle

  
  Hi all

  Any new on Oracle Sql and I need expert input to solve a problem I have to join Oracle.

  Have a requirement as below, my reading of request as below.

  SELECT A.GCI, B.LOB_IND, B.CED_ID, C. LOB_DESCR OF CUSTOMER, CUSTOMER b, C from LOB

  WHERE A.PRIMARY_CED = B.CED_ID (+)

  AND B.LOB = C.LOB_DESCR (+)

  Output current:

  339850821 Y 7905108 banking services for businesses

  Null Null null 339492963

  Power required:

  GCI LOB_IND CED_ID LOB_DESCR

  339850821 Y 7905108 banking services for businesses

  339492963 7859659 null null

  In the table B (CLIENT) for a ced_id there will be several entries.

  Select ced_id, LOB_IND from CLIENT b where b.ced_id = '7905108';

  ced_id LOB_IND

  7905108 IS

  Select ced_id, LOB_IND from CLIENT b where b.ced_id = 7859659;

  ced_id LOB_IND

  7859659 null

  7859659 null

  so when writing of the main request, I took B.LOB_IND (+) = 'Y' condition, since I added this condition and catches of outer join.

  the ced_id for "7859659" is not coming in the query below.

  SELECT A.GCI, B.LOB_IND, B.CED_ID, C. LOB_DESCR OF CUSTOMER, CUSTOMER b, C from LOB

  WHERE A.PRIMARY_CED = B.CED_ID (+)

  Is it possible that the query can be modified to get the below output with CED_ID for B.LOB_IND-> case of Null.

  Hi all

  I tried to use Dense_rank as below. But it gives me the top selling books. I need high library in each type...

  This looks like a job for 'PARTITION BY type

  For example:

  WITH got_rnk AS

  (

  SELECT b.bid, b.type

  SUM (o.quantity) AS total_quantity

  DENSE_RANK () OVER ( PARTITION BY b.type

  ORDER OF SUM (o.quantity) / / DESC

  ) AS rnk

  B BOOK

  o order1

  WHERE b.bid = o.bid

  GROUP BY b.bid, b.type

  )

  SELECT total_quantity, type submission

  OF got_rnk

  WHERE rnk = 1

  ;

  . Aggregate functions (such as the SUM, above) are calculated before analytical functions, so an analytic function (such as DENSE_RANK above) may depend on an aggregate function; you don't need a separate subquery for that.

• SQL Query Help (not working not properly)

  Hello everyone,

  I use JDeveloper 12.1.2.0.0. I do a two-way communication using 3 tables, with links between them (and using schema HR).

  In my example, I have something like:

  Departments, employees, and the SalaryByJobs (I created this table where it shows a departmentd id, employee id, salary).

  Whenever I click on one OR more departments, the employees up-to-date table by putting on the table, employees who belong to the selected department and the salaryByjob to put the jobs of the employees selected on the employees table.

  So it's something like this:

  The departments selected-> employees selected-> salarybyjbobs of these employees.

  My query used (in the view) has the following code:

  SELECT Employees.COMMISSION_PCT,

  Employees.DEPARTMENT_ID,

  Employees.EMAIL,

  Employees.EMPLOYEE_ID,

  Employees.FIRST_NAME,

  Employees.HIRE_DATE,

  Employees.JOB_ID,

  Employees.LAST_NAME,

  Employees.MANAGER_ID,

  Employees.PHONE_NUMBER,

  Employees.SALARY

  Employees EMPLOYEES

  WHERE (department_id IN (select * from THE (select cast (in_list(:variavel3) as mytableType) double) a))

  Since I use the links, the employees table does not show anything at the beginning, so I added this to my query used to go: OR nvl(:variavel3,0) = 0

  But now, whenever I try to select multiple lines, it gives me the invalid numbers and I don't understand why...

  It's only one line of code and it is not in the bean.

  Can someone help me?

  PS - The bean will Department by Department, adds the departments with ',' and for each Department, gets employees who belongs to them.

  My best regards,

  Frederico Barracha.

  The expression NVL (: variavel3, 0) = 0 is not correct. The data type of the return value of the NVL function is considered to be equal to the data type of the argument of 1 (that is, the data type of the variable binding: variavel3). You said that this variable contained a list separated by commas to ID, so the data type of the variable is VARCHAR2. As long as you compare the NVL expression of a number, you get 'Invalid number' exception, because Oracle expects a numeric data type on the left side of the comparison operator.

  To avoid the exception "Invalid number", you can modify the expression by using one of the following options:

  : variavel3 IS NULL

  NVL (: variavel3, ' *') = ' *'

  NVL (: variavel3, ' 0') = '0'

  Option 1, so the simplest and clearest.

  Hello

  Another way, which could be more efficient (but less clear):

  WITH   got_grp         AS
  (
       SELECT     CASE WHEN rtype = 'Q' THEN seq_r ELSE doc_r END     AS grp
       ,     CASE WHEN rtype = 'Q' THEN 0     ELSE 1     END     AS r_val
       FROM     yourtable
       WHERE     rtype  IN ('Q', 'R')
  )
  SELECT       COUNT (COUNT (*))     AS grp_cnt
  FROM       got_grp
  GROUP BY  grp
  HAVING       COUNT (*)     = SUM (r_val)
  ;
  

  You have not said if a line where
  rtype = 'R' and doc_r has the value NULL is considered to be a match for a line where
  rtype = 'Q' and seq_r is NULL.

  In the application of Cyn, they are not a match.
  In the above query, they are.
  A query can be changed for a different result.

• SQL monitor help with column of chronology

  

  In the report attached to sql, in the timeline column means the whole last 3 began simultaneously and hash join is the first exploited who started?

  my understanding is 'index range scan' should start first and give the data to "Single Partition range". Only once this step completed, he should 'TABLE ACCESS Full'. Isn't this correct?

  Thanks for your time!

  Your description is correct - and I think that you just have to allow some defects in the rounded, graphic display of errors and inconsistencies in what is "the order of execution.

  If it is still possible, you can watch dbms_sqltune.report_sql_monitor output text () as numbers COULD clarify the sequence - on the other hand, the granularity of the timer is not very fine.

  You may find that the chronology of hash join begins before the access times two table - which highlights the problem of "means to launch an operation."  The subroutine "do a hash join" must begin before the two tablescans, on the other hand the mechanism 'return rowsource to parent' cannot start until after the second table access began to return the hash join lines.

  Another sign of the available seeds, of course, is that the select statement does not seem to have started until a few seconds after the hash join has started!

  If we found the dates duplicate, we need update COL3 value with the previous value of max (date) value COL3.

• Need help with join

  I have a problem with the join, I try to use it to eliminate the mass number of path layers and sublayers I. Everything is already connected by anchor point but they have all of the separate layers and it is heavy for shipping and export.

  Here's what I want to join, lines are in place and, even once, the anchor points are connected. I want to keep this form:

  

  And that's what he keeps to:

  

  Any suggestion is welcome.

  dmuir,

  You can reach only two segments of track at the same time, so that each (no end) Anchor Point has only two adjacent segments.

  You can combine paths and creating paths compound and other things, but you're stuck with a number of roads as building blocks.

• SQL query date with century / year

  We have a database of oracle with about 6 million documents. There is a date field called Date entered from 1985 to the present day.
  Most of these recordings was entered into before January 1, 2000.
  If I run a query like
  Select count (*) (TableName) where entered_date < 1 January 00 ' I get 0
  If I do
  Select count (*) (TableName) where entered_date < 31 December 99 ' I get 0
  BUT IF I DO
  Select count (*) (TableName) where entered_date < 1 January 00 ' get 6 million documents
  or
  Select count (*) in the TREASURY.ctrc where entrydate > 31 December 99 ' get 6 million documents
  
  I tried the same queries using 4 digit years but get the same results. He thinks that 2000 is at least 1999
  How to do this?
  Thank you

  Hello

  There are 6 million documents on the table
  about two-thirds have a date prior to 1 January 2000

  How do you know this? Knowledge of the application, you can find out that two-thirds of them are supposed to have dates from before 2000, but if

  SELECT  COUNT (*)
  FROM      TABLE_NAME
  WHERE      ENTRYDATE < TO_DATE ( '01-JAN-2000'
                         , 'DD-MON-YYYY'
                     )
  ;
  

  Returns the value 0, which has strong enough evidence that none of them actually do.

  When I look at the dates, they appear as December 31, 86

  Another example of why use 2 digit years is a bad idea.

  I can't actually provide these confidential customer data dump

  Seriously; You can provide an output DUMP? You already said that it displays as December 31, 86, so even if the fact that 1 entry in the table of the line 6 million was made on December 31, 1986 was such a big secret, he is already out, and you don't cause any harm more by showing the results of DUMP.

  I ran the query with the same format as the date, that is to say
  SELECT COUNT (*) FROM THE DEPARTMENT OF FINANCE. CRTC WHERE ENTRYDATE< to_date="" (="">
  "DD-MON-YY."
  )

  but same results
  If the column is defined as a DATE type, Oracle made a distinction based on the way the data is displayed, which means that she think that December 31, 86 is different from December 31, 1986?

  No, all the DATE columns have the same format. A DATE can be displayed in one way of the other, but it is stored in the form of or.

  Should I convert all the data from one year to 4 digits?

  A 4-digit year dates should be always displayed.

  Run an update query that said if year > = 80 and<= 99="" add="" 19="" in="" front="" of="" the="" year,="" else="" add="" 20="" in="" front="" of="" the="">

  We will find out exactly what the problem is, first of all.

  Have you seen the Ascheffer message? ^ 1 ^ it was dated just a couple of minutes before your last post, so you might not notice. Run it to see what are the years of 4 real numbers.
  If it shows, for example, there are a lot of entrydates in the years 2080 to 2099, and if you decide that all who should really be 100 years earlier, use ADD_MONTHS to remedy:

  UPDATE     table_name
  SET     entrydate = ADD_MONTHS ( entrydate
                             , -100 * 12
                        )
  WHERE   entrydate >= TO_DATE ( '01-JAN-2080'
                           , 'DD-MON-YYYY'
                      )
  AND     entrydate <  TO_DATE ( '01-JAN-2100'
                           , 'DD-MON-YYYY'
                      )

• SQL query help (we connect by clause level)

  Hi all
  I have this application developed with data with the clause.

   With dat As

  )
  Select regexp_substr( col1 , '[^@][A-Z]+',1,level) Show from dat

  I need some changes on my request and I am not able to see that. So anyone can add to that or can also provide a different solution also.
  
  Thank you!
  Ashutosh

  Thanks for providing the loan to the use of query. :)

  Here's a solution :-(tested on 10 g, do not have 11 g at hand)

  For 11g, just use regexp_count instead of functions of the length.

  With dat As
  (
    select '@AAA @SSS @DDD' col from dual union all
    select '@ZZZ @XXX @TTT @RRR @ZZA' col1 from dual
  )
  Select regexp_substr( col, '[^@][A-Z]+',1,level) Show from dat
  connect by nocycle level  <= length(col) - length(translate(col, 'A@', 'A'))
         and col = prior col
         and prior sys_guid() is not null;
