• Need help for query joining views

  Hi all

  I need to run a query that joins a number of tables with multiple instances of the same view.  For example, a view named MY_VALUES, is an array of key / value resembles the following:

  Application_ID Attirbute_Description value

  1 1 000 basic benefit

  1 multiplier 1 0.5

  1 Multiplier_2 1.2

  1 total profit 1,115

  2 1 025 basic benefit

  2 multiplier 1 0,268

  2 Multiplier_2 1.3

  Total profit 2 1.4500

  Say I want a query that selects basic earnings and a multiplier 1 for Application ID 1, as well as, other information from a table called APPLICATION that has a relationship to display pk - fk. I would do the following:

  Select the application. Name, mv1.value, mv2.value

  from dbo. App APPLICATION, dbo. MY_VALUES mv1, dbo. Mv2 MY_VALUES

  where app.id = mv1.application_id and mv1.attribute_description = "Basic benefits"

  and app.id = mv2.application and mv2.attribute_description = id 'multiplier 1'.

  and app.id = 1

  My actual query is similar to this. However, I have many other attributes of the notice I need to select, which requires that the view be attached to several times. After 16 these joins, the request is fine. After 17, however, the query runs always, never return a result within 45 minutes I have let it run.

  Is there a better way to write such a request or an indicator of optimization that would be useful here?

  Any help is greatly appreciated.

  ....

  For this type of application, it is often best to extract multiple lines in a single request on the view and their pivot in the output.

  For example

  Select the application. Name

  , max (CASE when mv.attribute_description = "Core service" then mv.value any other purpose) BaseBenefit

  , max (CASE when mv.attribute_description = 'Multiplier 1' then mv.value any other purpose) Multiplier1

  , max (CASE when mv.attribute_description = 'Multiplier 2' then mv.value any other purpose) Multiplier2

  , max (CASE when mv.attribute_description = 'Multiplier 3' then mv.value end to another null) Multiplier3

  from dbo. App APPLICATION, dbo. MY_VALUES mv

  where app.id = mv1.application_id

  and mv.attribute_description IN ('benefits of home', 'multiplier 'multiplier 'multiplier 3' 2' 1')

  and app.id = 1

  This runs often much better than several joins to the table for the view or the value of the attribute.

• Help with time operations invloving the SQL query

  I created 2 tables in my SQL. One is the user_info_table table that stores the connection time and time zone of login for each user. The other is the post_table that stores user postid, who makes the post time post and time zone for each message.
  

  CREATE TABLE user_info
  (
  user_id VARCHAR(20), 
  login_date DATE,
  login_time_zone VARCHAR(20),

  );

  CREATE TABLE post_table

  I need to write a SQL query which - is the user whose time difference between the time of the connection and the last time when he or she wrote a post is the smallest. I need to consider the time zones here as well.
  
  I am not sure if time_zone must be of type VARCHAR or TIMESTAMP then have created as a VARCHAR in my paintings.

  You can do this by adding a clause of "HAVING" as shown below. However, with your test defined data it returns ZERO rows because for all users of the MAX (DATEPOST) IS LESS than MAX (LOGIN_DATE)

  SELECT     USER_ID
  FROM
  (
       SELECT     USER_ID
       ,     DENSE_RANK() OVER (ORDER BY POST_LOGIN_DIFF) RNK
       FROM
       (
            SELECT     USER_INFO.USER_ID
            ,     MAX(DATEPOST) - MAX(LOGIN_DATE) AS POST_LOGIN_DIFF
            FROM     USER_INFO
            JOIN     POST_TABLE     ON POST_TABLE.USER_ID = USER_INFO.USER_ID
            GROUP BY USER_INFO.USER_ID
            HAVING      MAX(DATEPOST) > MAX(LOGIN_DATE)

• Query Join help

  Hello:
  
  I need help to write my side of my SQL statement join.
  
  I have four tables with the following fields. The State tables, specialty and Classification are just tables of research.
  1 Organization->
  -ORG_KEY (PK) NOT NULL default (null)
  -STATE_KEY (FK) NOT NULL default (null)
  -SPECIALITY_KEY (FK) NOT NULL default (null)
  -CLASSIFICATION_KEY (FK) default NULL (null)
  
  2 State->
  -STATE_KEY (PK) NOT NULL default (null)
  -NAME NOT NULL default (null)
  -CODE NON default NULL (null)
  
  3 specialty->
  -SPECIALITY_KEY (PK) NOT NULL default (null)
  -NAME NOT NULL default (null)
  -CODE NON default NULL (null)
  
  4 classification-->
  -CLASSIFICATION_KEY (PK) default NULL (null)
  -NAME NOT NULL default (null)
  -CODE NON default NULL (null)
  
  When I run my select (using SQL Developer) and the SPECIAILITY_KEY and CLASSIFICATION_KEY fields are NOT filled (they have a null value appear as their value), I get no results and in the Express Application, I get an error message indicating "no data found".
  
  At the point where I have enter values in these two areas, the query returns records lines.
  
  When I try to insert a record and do not include a value for SPECIALITY_KEY and CLASSIFICATION_KEY, I get the following error message:
  ORA-01400: cannot insert NULL into ('TEST'. "ORGANIZATION '." "" ""CLASSIFICATION_KEY")."
  
  This is my SELECT statement:

  select a.org_key, 
       e.org_key||' - '|| e.name as parent, 
       e.name as name1, 
       a.sponsor, a.subscriber, a.provider,

       a.short_name, a.name, a.status, a.external_id, a.tin, a.region,
       a.address_line_1,a.address_line_2, a.city, 
       b.state_cd||' - '|| b.name as state, a.zip,
       a.zip_plus_four, a.live_date, a.contact_salutation, a.contact_first_name,

    and a.classification_key = c.classification_key
    and a.speciality_key = d.speciality_key
   and a.parent_org_key = e.org_key

  If I do not write the WHERE clause with all joints, I received several entries for the same record. With this WHERE clause, my query returns one record per org_key.
  
  Now, at the time where the user creates an org, the user can ignore the specialty or classification so they would be leave the field blank. It is a legitimate situation.
  How can I write my application so if a null value appears in a field, I always get the results?
  
  I would like to see all of my folders without worrying if the fields have a real value or display a NULL value. Showing records that have a NULL value, the user can see what information is missing and later come back and enter.
  
  Can someone help me?
  Thank you.

  Hello

  The CREATE TABLE instructions work when you run? I get a lot of errors, lack of parentheses and commas. Also, many to INSERT it IN the ORGANIZATION of statements fail because the parent records are missing. To get things to work, I ignored all the constraints.

  To change your original query so that all ranks of orgainaztion appears, if it has a corresponding line in any other tables, maike all the join conditions outer joins. For example:

   where a.state_key = b.state_key                  (+)
    and a.classification_key = c.classification_key (+)
    and a.speciality_key = d.speciality_key         (+)
   and a.parent_org_key = e.org_key            (+)
  

  If a match is not in any of the tables b, c, d or e, all columns of the table without a match will be displayed with a NULL value.

• What is the best way to optimize a SQL query: call a function or doing a join?

  Hi, I want to know what is the best way to optimize a SQL query, call a function inside the SELECT statement, or make a simple join?

  It depends on.  Could be a.  Could be the other.  Could be no difference.  You would need to compare with your tables in your environment with your settings.

  If you put a gun to my head, I was given no other information and required that I answered the question, I would tend to wait that the join would be more effective.  In general, if you can do something in pure SQL, it will be more effective than if you call PL/SQL.

• Case Based Condition of inner join in SQL query

  Hi Experts,
  

  CREATE TABLE PRODUCT_PRICE(PRODUCT_ID INTEGER,PRICE FLOAT);
  INSERT INTO PRODUCT_PRICE VALUES(1,1);
  INSERT INTO PRODUCT_PRICE VALUES(2,2);
  INSERT INTO PRODUCT_PRICE VALUES(3,1);
  INSERT INTO PRODUCT_PRICE VALUES(4,1);
  INSERT INTO PRODUCT_PRICE VALUES(5,3);
  INSERT INTO PRODUCT_PRICE VALUES(0,4);

  CREATE TABLE PRODUCT_TABLE (PRODUCTID INTEGER,OTHERID INTEGER);
  INSERT INTO PRODUCT_TABLE VALUES (1,0);
  INSERT INTO PRODUCT_TABLE VALUES (2,0);
  INSERT INTO PRODUCT_TABLE VALUES (3,1);
  INSERT INTO PRODUCT_TABLE VALUES (4,1);
  INSERT INTO PRODUCT_TABLE VALUES (5,2);

  I need to match the product_id = 0 to get the price of the product when there is othersid in the product table (otherid > 0). For this I created the query below.
  

  SELECT 
      PRODUCT_ID,
      PRICE 
  FROM 
      PRODUCT_TABLE
      INNER JOIN PRODUCT_PRICE ON PRODUCT_ID=PRODUCTID
  WHERE
      OTHERID=0
  UNION ALL
  SELECT 
      PRODUCT_ID,
      PRICE 
  FROM 
      PRODUCT_TABLE
      INNER JOIN PRODUCT_PRICE ON PRODUCT_ID=0
  WHERE
      OTHERID>0;

  My Question is, is that any way the SQLQuery above can be simplified in CASES and INTERNAL CONDITION JOIN in a single SQL QUERY?
  
  I can work around something like that,
  

  SELECT 
      PRODUCT_ID,
      PRICE 
  FROM 
      PRODUCT_TABLE
      INNER JOIN PRODUCT_PRICE ON * CASE WHEN OTHERID>0 THEN PRODUCT_ID=0 ELSE PRODUCT_ID=PRODUCTID END*

  Thank you

  SELECT CASE WHEN PT.OTHERID = 0 THEN PT.PRODUCTID ELSE 0 END AS PRODUCT_ID, PP.PRICE
    FROM PRODUCT_TABLE PT,  PRODUCT_PRICE PP
      WHERE CASE WHEN PT.OTHERID =0 THEN PT.PRODUCTID ELSE 0 END = PP.PRODUCT_ID
  

  Should it?

  I am trying to write a SQL query - for each country of the users, showing the average number of positions
  
  I understand the logic behind all this that we must first consolidate all locations, and then the users in one country and then find the way to their positions.
  But, I'm having a difficulty to this format SQL. Could someone help me please with this request.
  
  Thank you.

  Select
  Country.Country,
  Count (*) Totalpostspercountry,
  Count (distinct post.user_id) Totaldistincuserspercountry,
  count (*) / count (distinct post.user_id) Avgpostsperuserbycountry
  Of
  countries, have, post
  where country.location_id = muser.location_id
  and muser.user_id = post.user_id
  Country.country group

  The output is like this for your sample data - hope that's what you're looking for :)

  COUNTRY, TOTALPOSTSPERCOUNTRY, TOTALDISTINCUSERSPERCOUNTRY, AVGPOSTSPERUSERBYCOUNTRY
  In England, 1, 1, 1.
  Spain, 5, 2, 2.5.
