How to write sql query for counting pairs from below table??

Below is my SQL table structure.
user_id | Name | join_side | left_leg | right_leg | Parent_id
100001 Tinku Left 100002 100003 0
100002 Harish Left 100004 100005 100001
100003 Gorav Right 100006 100007 100001
100004 Prince Left 100008 NULL 100002
100005 Ajay Right NULL NULL 100002
100006 Simran Left NULL NULL 100003
100007 Raman Right NULL NULL 100003
100008 Vijay Left NULL NULL 100004
It is a binary table structure.. Every user has to add two per id under him, one is left_leg and second is right_leg... Parent_id is under which user current user is added.. Hope you will be understand..
I have to write sql query for counting pairs under id "100001". i know there will be important role of parent_id for counting pairs. * what is pair( suppose if any user contains both left_leg and right_leg id, then it is called pair.)
I know there are three pairs under id "100001" :-
1. 100002 and 100003
2. 100004 and 100005
3. 100006 and 100007
100008 will not be counted as pair because it does not have right leg..
But i dont know how to write sql query for this... Any help will be appreciated... This is my college project... And tommorow is the last date of submission.... Hope anyone will help me...
Suppose i have to count pair for id '100002'. Then there is only one pair under id '100002'. i.e 100004 and 100005

Sounds like this to me
DECLARE @ID int
SET @ID = 100001--your passed value
SELECT left_leg,right_leg
FROM table
WHERE (user_id = @ID
OR parent_id = @ID)
AND left_leg IS NOT NULL
AND right_leg IS NOT NULL

How to create sql query for item master with operator LIKE with variables?

hi all,
How to create sql query for item master with
operator LIKE(Contains,Start With,End With) with variables using query generator in SAP B1 ?
Jeyakanthan

Hi Jeyakanthan,
here is an example (put the like statement into the where field)
SELECT T0.CardCode, T0.CardName FROM OITM T0 WHERE T0.CardName Like '%%test%%'
The %% sign is a wildcard. If you need start with write 'test%%' and otherwise ends with '%%test'. For contains you need '%%test%%'. You also could combinate this statements like 'test%%abc%%'. This means starts with test and contains abc.

How to write a query for AFTER DATE

Hello Experts,
I’m new to SQL and stuck on a query. How would you write SQL Code for the following query:
The HR Department wants to determine the names of all employees who were hired after Davies:
Thanks in advance.

Hello,
You need to change to the table name you have in your schema and in this case its "employees". Don't hard code date in where clause you might have different requirement later ;)
SELECT *
FROM employees
WHERE hire_date > (SELECT hire_date
FROM employees
WHERE name = 'Davies');Regards

Trouble writing Query for Pivoting data from a table

I am having a little trouble writing a query for converting the below table data into a pivot data. I am trying to write a query for which if I give a single valid report_week date as input it should give me the data for that week and also provide two extra columns, one which gives the data of last week for the same countries and the second column which gives the difference of numbers in both the columns(i.e. COUNT - COUNT_LAST_WEEK).
REPORT_WEEK     DIVISION     COUNT
9/26/2009     country1     81
9/26/2009     country2     97
9/26/2009     country3     12
9/26/2009     country4     26
9/26/2009     country5     101
10/3/2009     country1     85
10/3/2009     country2     98
10/3/2009     country3     10
10/3/2009     country4     24
10/3/2009     country5     101
10/10/2009     country1     84
10/10/2009     country2     98
10/10/2009     country3     10
10/10/2009     country4     25
10/10/2009     country5     102
For example, if I give input as 10/10/2009, the output should be as give below.
REPORT_WEEK     DIVISION     COUNT     COUNT_LAST_WEEK     DIFFERENCE
10/10/2009     country1     84     85     -1
10/10/2009     country2     98     98     0
10/10/2009     country3     10     10     0
10/10/2009     country4     25     24     1
10/10/2009     country5     102     101     1
For example, if I give input as 10/3/2009, the output should be as give below.
REPORT_WEEK     DIVISION     COUNT     COUNT_LAST_WEEK     DIFFERENCE
10/3/2009     country1     85     81     4
10/3/2009     country2     98     97     1
10/3/2009     country3     10     12     -2
10/3/2009     country4     24     26     -2
10/3/2009     country5     101     101     0
Can anyone please shed some light on Query building for the above scenarios.
Thank you

How to write SQL hints for this query?

The query is like:
select * from foo, t
where foo.name in
(select name from bar
where id in (
select id from car
where date < sysdate
and foo.a = t.b;
I want the innermostsubquery 'select id from car ...' to be executed first, and the subquery 'select name from bar ...' to be execute second, and the outermost query 'select * from foo,t ...' to be executed the last. How can I write the Oracle sql hints to force the order?
Thanks.

user553560
You might be able to create a large set of hints to force the access path you want - but unless you really know what you are doing with hints, you may find that your solution is very unstable (it might be luck rather than correctness that let's it work to start with).
The difficulty in this query is the double layer of IN subqueries, so if you can rewrite the query, you might try manually unnesting as follows:
select
     t1.*. t.*
from
          select
               distinct t2.name
          from     t2
          where     t2.id in (
                    select     t3.id
                         from     t3
                    where     t3.dated < sysdate
     )     v,
     t1,
     t
where
     t1.name = v.name
and     t1.a = t.bDepending on your indexing and statistics, you may find that a simple /*+ unnest */ hint in the first subquery will be sufficient to do this for your. Again depending on the statistics you may find that you have to put extra hints into the above to make Oracle use the join method and indexes you think appropriate.
N.B. The first step (as others have noted) is to check that your statistics are good before you start manipulating the code or using hints.

How to write select query for this

Hi,
I had a html form and in the for i had drop down box and it needs to select multiple values from the drop down box. When i select multiple values then i have to write the SQL select statement query .
When i try to write the select statement and trying to run i am getting error.
select * from Table
where emo_no = '1,2,3'
this is how i write query please suggest me how to write query for selecting multiple values from the drop down box.
Thanks

select * from Table
where emo_no in ( 1,2,3)
for integer values
select * from Table
where emo_no in ('1','2','3')
for characters
If we talk about large scale applications that may have millions of records, I would suggest this.
declare @t table (v int)
insert into t (v) values (1)
insert into t (v) valves (2)
insert into t (v) values (3)
select *
from table
inner join @t t on table.emo_no = t.v
Using "in" for a where clause is not so bad for filtering on a few values, but if you are filtering a lot of rows and a lot of values (emo_no) the performance degrades quickly for some reasons beyond the scope of this.
This is just one solution, I'll through this out as well, instead of an in memory (@t) table, doing a disk based temp table (#t) and creating an index on the column "v".
create table #t (v int)
insert into #t (v) values (1)
insert into #t (v) valves (2)
insert into #t (v) values (3)
create index ix_t on #t (v)
select *
from table
inner join #t t on table.emo_no = t.v
drop table #t
Pardon any syntax errors and careful using a drop statement.
Sometimes in memory tables work better than disk temp tables, it takes some testing and trial and error depending on your datasets to determine the best solution.
Probably too much info ;-)

In general case, you cannot write this query.
This is one of the limits of relational database concepts. The number of columns must be known up-front. In the SELECT clause, you have to list and name all columns returned by the query. So you have to know number of departments. (There are some workarounds - you can return one column with concatenated values for all departments, separated by space character).
If you know that you have 3 departments then you qurey will return 4 columns:
SELECT
   e.job,
   SUM ( CASE WHEN d.deptid = 10 THEN e.sal ELSE NULL END) d10,
   SUM ( CASE WHEN d.deptid = 20 THEN e.sal ELSE NULL END) d20,
   SUM ( CASE WHEN d.deptid = 30 THEN e.sal ELSE NULL END) d30
FROM dept d, emp e
WHERE d.deptno = e.deptno
GROUP BY e.job
