Help me write a SQL query; urgent

Hi, can somebody please help me write a SQL query.
I have 3 tables each with the same column names (Col1, Col2, Col3). Col1 is PK with Unique Constraint.
I wanted to add values of Col2 and Col3 (from all 3 tables) and put it in a separate table (i.e aggregated) of all values found in Col1.
Does anybody help me please ?
thanks alot.

Please don't mark your question as urgent. You've been around here long enough that you should know that it will not get your question anwered any faster, and may just irritate people into not answering at all.
I'm not sure exactly what you want.
Are you saying you want t1.c2 + t1.c3 + t2.c2 + t2.c3+ t3.c2 + t3.c3 for the rows that have the same c1 in all three tables?
If so, it would be like this, I think: insert into t4
select t1.c1
, t1.c2 + t1.c3 + t2.c2 + t2.c3+ t3.c2 + t3.c3
from t1, t2, t3
where t2.c1 = t1.c1
and t3.c1 = t1.c1If that's not what you want, please clarify.
And next time maybe you should post your SQL question in a SQL forum.

Help to write following SQL query?

Hey, beginner hopes to get some help from pro's.
Please write SQL query to select only green and yellow fruits that are in stock and output results sorted by fruit name in ascending order.

Thanks in advance!

If your database and SQL server use default SQL Server collation which is case insensitive, then drop lower function from the suggested script and use
color in ('green', 'yellow')

Help to write an sql query

Hi everyone!
I need some help in composing a query that would calculate the number of occurrences of '29-Feb' between 2 given dates (i.e. substitution variables).
What I figured so far is a way too complex and don't work all the time. Also I do know, that calculating a leap year is a bit different than just year mod 4 = 0.
I would appreciate very much if you help me to write this query or just give me a guess.
SELECT TO_NUMBER(TO_CHAR(date2, 'YYYY')-TO_CHAR(date1, 'YYYY'))/4

Hi,
Interesting problem!
The query below looks at the 59th day after January 1 in each year.
If that date was in February, then it was a leap year.
If that date was not in February, then it was a common year.
DEFINE     date1     = "TO_DATE ('07-11-1609', 'DD-MM-YYYY')"
DEFINE     date2     = "TO_DATE ('06-11-2009', 'DD-MM-YYYY')"
WITH     all_years AS
     SELECT     ADD_MONTHS ( TRUNC (&date1, 'YYYY')
                  , 12 * (LEVEL - 1)
                  ) + 59       AS dt
     FROM     dual
     CONNECT BY     LEVEL <= 1 + CEIL ( MONTHS_BETWEEN ( &date2
                                                     , &date1
                           / 12
SELECT     COUNT ( CASE
               WHEN TO_CHAR (dt, 'MM') = '02'
               THEN 1
          END
           )          AS leap_year_cnt
FROM     all_years
WHERE     dt     BETWEEN      &date1
          AND      &date2
;A less efficient (for what that's worth) way is to generate all dates between &date1 and &date2, and test each one to see if it is '02-29'.
I'll leave that as an exercise to the reader.
HINT: the coding is simpler than the query above. (In my prolix style, it took 10 lines. No sub-query is needed.)

Help needed in framing SQL query.

Hi,
I have table having following schema:
PRODUCT_ID         INT
DATE                   DATETIME
ITEMS_SOLD         INT
This table contains data for a week (sunday to saturday). I want to write an SQL query to get (filter out) PRODUCT_ID of products which has same no. of ITEMS_SOLD for all 7 days. Also for given PRODUCT_ID I need to find the longest period of successive days where the no. of ITEMS_SOLD is same for all days in this period. Eg.(PRODUCT_ID 23 was sold as following along the week in no. of units sold: 4,6,6,6,6,7,4 .So the longest period is *4 days* from Monday to Thursday.) The first condition is special case of second condition where no. of days is 7.
Any help to get the SQL query will be appreciated.
Thanks,
Akshay.

PRODUCT_ID      DATE           ITEMS_SOLD
1          10/10/2011     3
1          11/10/2011     3
1          12/10/2011     3
1          13/10/2011     3
1           16/10/2011     5
2          10/10/2011     4
2           11/10/2011     4
2          12/10/2011     4
2          13/10/2011     4
2           14/10/2011     4
2          15/10/2011     4
2          16/10/2011     4
Output:
PRODUCT_ID ITEMS_SOLD NO_OF_DAYS
1          3                4
2          4               7
Explanation of results:
The table to be queried contains data for 1 week: from 10/10/2011(Sunday) to 16/10/2011(Saturday). Now, product with PRODUCT_ID '1' was sold on dates 10,11,12,13,16. Out of these 5 days 3 units were sold on 4 successive days (from 10-13). So output should be like :
PRODUCT_ID ITEMS_SOLD NO_OF_DAYS
1          3               4
as longest period of successive days is 4 where same no. of units were sold i.e 3 units (other period is of 1 day on 16th ).
For PRODUCT_ID 2 we have only one period of 7 days where 4 units were sold each day. So we output :
PRODUCT_ID ITEMS_SOLD NO_OF_DAYS
2           4               7
Other case where same PRODUCT_ID have different units sold on each day should be ignored.
I hope that clarifies the problem more. Let me know in case I have missed out anything which should have been mentioned.

Please help me with this SQL query

I am practicing SQL queries and have come across one involving fetching data from 3 different tables.
The three tables are as below
<pre>
Country
location_id          country
loc1          Spain
loc2          England
loc3          Spain
loc4          USA
loc5          Italy
loc6          USA
loc7          USA
</pre>
<pre>

</pre>
<pre>
Post
post_id user_id
p1 u1
p2 u1
p3 u2
p4 u3
p5 u1
p6 u2
</pre>
I am trying to write an SQL query - for each country of users, display the average number of posts
I understand the logic behind this that we first need to group together all the locations and then the users belonging to one country and then find the average of their posts.
But, i'm having a difficulty in putting this in SQL form. Could someone please help me with this query.
Thanks.

select
country.country,
count(*) Totalpostspercountry,
count(distinct post.user_id) Totaldistincuserspercountry,
count(*)/count(distinct post.user_id) Avgpostsperuserbycountry
from
country, muser, post
where country.location_id = muser.location_id
and muser.user_id = post.user_id
group by country.country
The output is like this for your sample data - hope this is what you were looking for :)
COUNTRY,TOTALPOSTSPERCOUNTRY,TOTALDISTINCUSERSPERCOUNTRY,AVGPOSTSPERUSERBYCOUNTRY
England,1,1,1,
Spain,5,2,2.5,

Need help in rewriting a sql query

Can any one please tell me if there is any utility that can help me correcting the sql I have I need to tune the query as its taking lot of time. I want to use some tool that will help me re-formating the query.
Any help in this regard will be highly appreciated.

If you think that Oracle SQL Tuning Tools like SQL Tuning Advisor and SQL Access Advisor are not helping.
You might look into thrid party tools like Quest- SQL Navigator and TOAD.
But I don't advise this based on the following:
Re: Oracle Third Party Tools and Oracle Database
Oracle have enough tools of its own to satisfy the various needs.

How to write a sql query to retrieve data entered in the past 2 weeks

Hi,
I have file names and last accessed date(java.sql.Date format) stored in my database table, I would like to know how I can write a query to get the name of files accessed in the past 2 weeks,I use open sql server at the back end.
Thanks in advance.

This has essentially nothing to do with JDBC. JDBC is just an API to execute the SQL language using Java and thus interact with the databases.
Your problem is related to the SQL language, you don't know how to write the SQL language. I suggest you to go through a SQL tutorial (there is one at w3schools.com) and to read the SQL documentation which come along with the database in question. A decent database manfacturer has a website and probably also a discussion forum / mailinglist as well.
I'll give you a hint: you can just use equality operators in SQL like everywhere. For example: "WHERE date < somedate".

How to write a SQL Query without using group by clause

How To Write A Sql Query to Show 0's

I never can remember this :-/ What do I have to do to get a SQL Query to return 0 if the Count of a condition is 0? For example lets say Joe, Jay, Jim could log on, but only Joe & Jim logged in Jay would not be returned in the query below. What
would I need to set-up so that All 3 users would be returned
Select logonName, Count(Logon)
From logonUserInfo
where logonName is not nullGROUP BY logonName

Currently there is only 1 table involved. I would need a separate table? What would this table need to hold?
You wouldn't need a separate table unless and until you want to store who logged in at what time and so on... then your table structures looks like below..
CREATE TABLE loginnames
loginid INT
name VARCHAR(30),
GO
CREATE TABLE loginTimes
loginid INT,
logintime DATETIME
GO
So, now you can do a left join on both tables on a certain date directly and find out who actually logined and who didn't with a count 0 for the one's who didn't login... and that will abide the principles of normalization as well...
If you don't want to use an another table, you would have to duplicate the loginnames everytime that user logins and also you don't have a track on what date the login happened.. So you will be considering from day 1 to Till date...
Please mark as answer, if this has helped you solve the issue.

Hi All,
I am facing a problem with a report. I need your help.
I am creating a Report From SQL Query (Portal) with some arguments passed at runtime. I am able to view the output, if the query returns few rows ( arount 1000 rows). But for some inputs it needs to generate >15000 records, at this point the page is getting time out (i think!) and showing error page. I am able to execute query from the SQL Plus console ot using TOAD editor. Here the query is not taking more that 2 mins time to show the result.
If i am executing from Portal i observed that, once i give the appropriate input and hit submit button a new oracle process is getting created for the query on UNIX (I am usign "TOP" command to check processes). The browser page will be shown error page after 5 minutes (i am assuming session time out!) , but on the backend the process will be executed for more than 30 mins.
I tried also increase the page time out in httpd.conf, but no use.
The data returned as a result of the query is sized more than 10 MB. Is caching this much data is possible by the browser page? is the returned data is creating any problem here.
Please help me to find appropriate reasone for the failure?

There could be a variety of reasons for the delayed processing of this report. That includes parameter settings for that page, cache settings, network configurations, etc.
- explore best optimization for your query;
- evaluate portal for best performance configuration; you may follow this note (Doc ID: *438794.1* ) for ideas;
- third: for that particular page carrying that report, you can use caching wisely. browser cache is neither decent for large files, nor practical. instead, explore the page cache settings that portal provides.
- also look for various log files (application.log and apache logs) if you are getting any warnings reflecting on some kind of processing halt.
- and last but not the least: if you happen to bring up a portal report with more than 10000 rows for display then think about the usage of the report. Evaluate whether that report is good/useful for anything?

Help needed in executing SQL query...

Hi,
I am very new to JDeveloper. Curently i am tryin to execute an SQL query from the BPEL process, the output of the query is to be mapped to a variable field from a target xsd file. the query is fairly simple, like
SELECT emp
FROM emp_table
WHERE emp_id=123
The target field, namely "employee", is an element from the xsd file. I tried using Java embedding activity to connect to the db and execute the query through a piece of Java code, but couldn't find a way to assign the output of the query to the field. however lately i also discovered the Database Adapter services which helps me create a database connection, but still i am not sure as of how to handle and map the output of the query to the variable field.
Can somebody please help me in resolving the issue either through Java Embed activity or Database Adapter services??
Thanks in advance
Anjan
