How would I write this query

[USERNAME]
[GROUP]
User1
New Member
User2
New Member
User1
All Members
User1
Gold Member
How would I write a query so that I could select * from the above table where a user has more than 1 group (user1) and if one of the groups = 'All members' then ignore that row and just return the all the other rows for the user that has > 1 group.
Thanks in advance. I can write the query for counting if a user has more than 1 group, but I stuck on the rest.
Thanks again

Try this
declare @tab table(USERNAME varchar(10), Usergroup varchar(15));
insert into @tab values
('User1','New Member'),
('User2','New Member'),
('User1','All Members'),
('User1','Gold Member');
select * from
(Select *,ROW_NUMBER() OVer(partition by username Order by case when Usergroup ='All members' then 0 else 1 end desc) RN From @tab ) t
where t.usergroup= case when t.rn >1 and t.Usergroup='All members' then 'Do not return' else t.Usergroup end

How would you write this query efficiently?

I am having a problem doing a particular join in the most optimal fashion, and this kind of join I do often, so I'd like to learn the best way to do it so I can re-use the same logic every time and be comfortable that it is the most efficient means.
I am using Oracle 11g, and the situation goes like this -- well actually there is a variation of this particular situation, I'll explain the easier one first):
Table PARENT (
PARENT_ID NUMBER [PK],
(OTHER IRRELEVANT DATA COLUMNS)
Table CHILD (
CHILD_ID NUMBER [PK],
PARENT_ID NUMBER,
CHILD_VALUE VARCHAR2(50),
START_DATE DATE NULL(NO),
END_DATE DATE NULL(YES)
I want to query from PARENT, joining to CHILD when possible (e.g. an outer join) but I only want the MOST RECENT record. MOST RECENT means that it is the record with the latest START_DATE, which is a column that cannot be NULL.
I usually try a query where I make a inner SELECT in the FROM clauses, then do an outer join against it. But this seems ot be a terrible practice that slows the query down drastically, because looks like the DB analyzes that sub query for the entire DB before joining on my particular result set. Like the main query might filter it down very quickly to a small set of records, but that sub query still analyzes the entire table then joins to my subset. So something like this:
SELECT
p.(WHATEVER COLUMNS FROM PARENT),
x.CHILD_VALUE,
x.START_DATE,
x.END_DATE
FROM PARENT p,
(SELECT c1.PARENT_ID, c1.CHILD_VALUE, c1.START_DATE, c1.END_DATE
FROM CHILD c1
WHERE c1.START_DATE = (SELECT MAX(START_DATE) FROM CHILD)
) x
WHERE
p.(FILTERING ON PARENT)
AND x.PARENT_ID(+) = p.PARENT_ID
Then a variation of this is that the CHILD table has one other column:
CHILD_TYPE (NUMBER)
And I need to join on the CHILD getting the MOST RECENT record for each CHILD_TYPE... for this I do two inner queries usually, and again I know its not the right way to do it.

with most_recent_child as (
                           select *
                             from (
                                    select c.*,
                                            row_number() over(partition by parent_id order by start_date desc) rn
                                            from child c
                             where rn = 1
select *
from      parent p
        left join
            most_recent_child c
          on p.parent_id = c.parent_id
/SY.

Hi All,
Please look into the above data, If analytic function LAG(),CASE expression are possible to locate the cursor position in the single query, then any one can help me out about it. I tried but could not.

You can do this with the SUM analytic function. Taking the emp table, for example,
1 select ename, sal, SUM(sal) OVER (order by empno)
2    from emp
3* order by empno

How can I write this query In parameterize form so That I can prevent sql Injection

String strQry = "INSERT INTO tblVoucherType (VhrTypeCode,moduleCode,transCCode,"
+ "voucherType,OrderNumber,active,AccountId) "
+ " values('" + txtVhrCode.Text + "','" + ddlModule.SelectedValue.ToString() + "',"
+ "'" + ddlTrans.SelectedValue.ToString() + "','" + txtVhrName.Text + "','" + btnRadio.SelectedValue + "'"
+ ", '" + status.Checked + "', '" + txtAccount.Text + "')";

Basically it will look like:
String strQry = "INSERT INTO tblVoucherType (VhrTypeCode,moduleCode,transCCode, ...)"
+ " values(@VhrCode, @moduleCode, @transCCode, ....)";
sqlCommand.Parameters.AddWithValue("@VhrCode", txtVhrCode.Text );
sqlCommand.Parameters.AddWithValue("@moduleCode", ddlModule.SelectedValue.ToString() );
sqlCommand.Parameters.AddWithValue("@transCCode", ddlTrans.SelectedValue.ToString() );
.. and so on
sqlCommand.ExecuteNonQuery();

How to write this query to filter combination of few values

Hi,
I have a table CHIMM which is a transaction table and contains information of the vaccines given to a child.
columns are: child_id, vacc_id, vacc_given_dt. I have to query for remaining vaccines.
HEXA is a vaccine_id which is composite vaccine of DPT1,POL1,HBV1 & HIB1 (vaccine ids).
I want to write to query if any of DPT1,POL1,HBV1 & HIB1 given then HEXA should not be displayed in the result.
OR
if HEXA is given then of course any of DPT1,POL1,HBV1 & HIB1 should not be displayed in the result.
How to write this query?

Hi,
I'm still not sure what the output you want from that sample data is. Do you just want the child_ids, like this
CHILD_ID
       3
       4? If so, here's one way to get them:
WITH     all_vacc_ids     AS
     SELECT     c.child_id
     ,     c.vacc_id          AS child_vacc_id
     ,     v.vacc_id
     ,     COUNT ( CASE
                         WHEN c.vacc_id = 'HEXA'
                   THEN 1
                     END
                )       OVER ( PARTITION BY c.child_id
                                   )    AS hexa_itself
     FROM          vacc   v
     LEFT OUTER JOIN     chimm c     PARTITION BY (c.child_id)
                      ON     c.vacc_id     = v.vacc_id
     WHERE   v.vacc_desc       = 'HEXA'     -- See note below
SELECT       child_id
FROM       all_vacc_ids
WHERE       child_vacc_id     IS NULL
AND       vacc_id     != 'HEXA'
AND       hexa_itself     = 0
GROUP BY child_id
rha2 wrote:there are alot of vaccines, i just put 3 for example. this query gives error: invalid relational operatorAre you saying that the vacc table contains other rows, but those other rows are not needed for this problem? It would be good if you included an example in the sample data. The query above considers only the rows in vacc where vacc_desc='HEXA'. You can have other rows in the vacc table, but they won't affect the output of this query. The query above makes no assumptions about the number of rows that have vacc_desc='HEXA'; it will report all child_ids who are missing any of them, regardless of the number (assuming the child does not have the 'HEXA' vacc_id itself, like child_id=1).
You still haven't said which version of Oracle you're using. The query above will work in Oracle 10 (and higher).

How to write this query ?

how to write this query ?
list the emp name who is working for the highest avg sal department.
I can use row_number over to get correct result. If we don't use this row_number function, just plain sql, how to do it ?
the row_number version is like this
select emp.* from emp ,
select deptno, row_number() over (order by avg(sal) desc) r from emp
group by deptno
)e
where e.r = 1
and emp.deptno = e.deptno

ROW_NUMBER (or its close relative, RANK) is the simplest and most efficient way to solve this problem. Why not do this the right way?
the row_number version is like this
select emp.* from emp ,
select deptno, row_number() over (order by avg(sal) desc) r from emp
group by deptno
)e
where e.r = 1
and emp.deptno = e.deptno
If there happens to be a tie (that is, two or more departments have the same average sal, and it is the highest), then the query above will only arbitrarily treat one of them (no telling which one) as the highest. Change ROW_NUMBER to RANK to get all departments with a claim to having the highest average sal.
You could use the ROWNUM pseudo-column instead of ROW_NUMBER, if all you want to do is avoid ROW_NUMBER.
Without using ROW_NUMBER or RANK, there are lots of ways involving other analytic functions, such as AVG and MAX.
If you really, really don't want to use analytic functions at all, you can do this:
SELECT     *
FROM     scott.emp
WHERE     deptno     IN (
                  SELECT       deptno
                  FROM       scott.emp
                  GROUP BY deptno
                  HAVING       AVG (sal) = (
                                                   SELECT    MAX (AVG (sal))
                                           FROM          scott.emp
                                           GROUP BY deptno

How to re-write this big SELECT Query with INNER JOINs?

Hi Experts
I have a performance killer SELECT query with an inner join of 3 tables u2013 VBAP, VBAK and VBEP together, which populates records to an internal table INT_COLL_ORD. Based on these records selected, in another SELECT query, records are fetched from VBUK table to the internal table INT_VBUK.
SELECT A~VBELN A~POSNR A~MATNR A~KWMENG A~KBMENG A~ERDAT A~ERZET A~PSTYV D~AUART E~ETTYP E~EDATU

INNER JOIN VBEP AS E
ON E~VBELN EQ A~VBELN AND E~POSNR EQ A~POSNR AND E~MANDT EQ A~MANDT
WHERE A~VBELN IN s_VBELN AND

SELECT VBELN UVALL CMGST INTO TABLE INT_VBUK
FROM VBUK FOR ALL ENTRIES IN INT_TAB_RES
WHERE VBELN = INT_TAB_RES-VBELN AND UVALL NE 'A'.
Now, the requirement is:
I want to split this query. Like, first join VBAK and VBUK first. With this selection, go to the inner join of VBAP and VBEP (on key VBELN) to get the results. How can I re-write this Query?
Please help.

Please note that declaration for INT_COLL_ORD has a field AUART, which is used in further parts of program (see the statement just above)
But, since neither VBAP nor VBEP contains AUART field, it cannot be fetched through the QUERY#2. So this value is not populated into INT_COLL_ORD through SELECT Query.
Since this field is used in later part of program & that the internal table has no value for this field, it dumps!!
How to include this value into the INT_COLL_ORD?
Plz suggest....

How can i improve this query.

Hi guys i am beginner , just wanted to know some info , how can i improve this query ..
select *
from tableA A, viewB B,
where A.key = B.key
and a.criteria1 = '111'
and a.criteria2 = some_funtion(a.key)
one more thing should function should be on left side of equal sign.
will a join make it better or something else is needed more than that .

will a join make it better or something else is needed more than that .If you are a beginner try to learn the ANSI Syntax. This will help you a lot to write better queries.
Your select would look like this in ANSI.
select *
from tableA A
JOIN viewB B ON A.key = B.key
WHERE a.criteria1 = '111'
and a.criteria2 = some_function(a.key);The good thing here is that this separates the typical joining part of the select from the typical filter criteria.
The other syntax very often let you forget one join. Just because there are so many tables and so many filters, that you just don't notice correctly anymore what was join and what not.
If you notice that the number of column is not what you expect, you can easiely modify the query and compare the results.
example A
Remove View B from the query (temporarily comment it out).
select *
from tableA A
--JOIN viewB B ON A.key = B.key
WHERE a.criteria1 = '111'
and a.criteria2 = some_funtion(a.key)
example B
You notice, that values from A are missing. Maybe because there is no matching key in ViewB? Then change the join to an outer join.
select *
from tableA A
LEFT OUTER JOIN viewB B ON A.key = B.key
WHERE a.criteria1 = '111'
and a.criteria2 = some_funtion(a.key)(The outer keyword is optional, left join would be enough).

                GROUP BY sortest_pidm;


Hi,
That depends on whether spriden_pidm is unique, and on what you want for results.
Whenever you have a problem, post a little sample data (CREATE TABLE and INSERT statements, relevamnt columns only) for all tables, and the results you want from that data.
If you can illustrate your problem using commonly available tables (such as those in the scott or hr schemas) then you don't have to post any sample data; just post the results you want.
Either way, explain how you get those results from that data.
Always say which version of Oracle you're using.
It looks like you're doing something similiar to the following.
Using the emp and dept tables in the scott schema, produce one row of output per department showing the highest salary in each job, for a given set of jobs:
DEPTNO DNAME          LOC           JOB_1   SAL_1 JOB_2   SAL_2 JOB_3   SAL_3
    20 RESEARCH       DALLAS        ANALYST 3000 MANAGER 2975 CLERK    1100
    10 ACCOUNTING     NEW YORK      MANAGER 2450 CLERK    1300
    30 SALES          CHICAGO       MANAGER 2850 CLERK     950On each row, the jobs are listed in order by the highest salary.
This seems to be analagous to what you're doing. The roles played by sortest_pidm, sortest_tesc_code and sortest_test_score in your sortest table are played by deptno, job and sal in the emp table. The roles played by spriden_pidm, id and name in your spriden table are played by deptno, dname and loc in the dept table.
It sounds like you already have something like the query below, that produces the correct output, except that it does not include the dname and loc columns from the dept table.
SELECT    deptno

;Since dept.deptno is unique, there will only be one dname and one loc for each deptno, so we can change the query by replacing "deptno" with "deptno, dname, loc" throughout the query (except in the join condition, of course):

GROUP BY deptno, dname, loc                    -- Changed
;Actually, you can keep using just deptno in the analytic PARTITION BY clause. It might be a little more efficient to just use deptno, like I did above, but it won't change the results if you use all 3, if there is only 1 danme and 1 loc per deptno.
By the way, you don't need so many sub-queries. You're using the inner sub-query to compute the MAX, and the outer sub-query to compute rn. Analytic functions are computed after aggregate fucntions, so you can do both in the same sub-query like this:
SELECT    deptno, dname, loc
,       MAX (DECODE (rn, 1, job))     AS job_1
,       MAX (DECODE (rn, 1, max_sal))     AS sal_1
,       MAX (DECODE (rn, 2, job))     AS job_2
,       MAX (DECODE (rn, 2, max_sal))     AS sal_2
,       MAX (DECODE (rn, 3, job))     AS job_3
,       MAX (DECODE (rn, 3, max_sal))     AS sal_3
FROM       (
               SELECT    e.deptno, d.dname, d.loc
          ,       e.job
          ,       MAX (e.sal)     AS max_sal
          ,       ROW_NUMBER () OVER ( PARTITION BY e.deptno
                                       ORDER BY       MAX (sal)     DESC
                                      )       AS rn
          FROM      scott.emp    e
          ,       scott.dept   d
          WHERE     e.deptno        = d.deptno
          AND       e.job                IN ('ANALYST', 'CLERK', 'MANAGER')
              GROUP BY e.deptno, d.dname, d.loc
          ,       e.job
GROUP BY deptno, dname, loc
;This will work in Oracle 8.1 and up. In Oracle 11, however, it's better to use the SELECT ... PIVOT feature.

Is that something that can be done in Oracle in the same way?
Do you use another approach?
please advice

How can i write this C-Code in G-Code

hallo
how can I write this C-Code in LabVIew ,
for a=0; a=<10; a++
for b=0; b=5 ; b+2
X= 3+b;
Y=1+a;
please see the attachment and tell me where is the problem

Well, at least you tried and got some of it right.
I think this should do what you want, but my C is rusty. Is the increment performed before or after the loop executes? If it's after, then I believe the loop should iterate 11 times, not 10.
In any case, you should note that for a literal translation, you would need to add a sequence structure to guarantee that Y was written to only after the inner loop finished because of the way data-flow works.. Also, note that controls and indicators in LabVIEW are not equivalent to variables. They can be used as such, but they usually should not be.
Another point about this is that you probably want to use the correct data type - the orange terminals are floating point indicators (of double precision, in this case) and you want integers.
To learn more about LabVIEW, I suggest you try looking at some of these tutorials.
Try to take over the world!

I share my iTunes with my family's iPod's. We all buy music seperately on our own iPod and would like to transfer the music to our iTunes library, how would we do this?

Oh jeez, that was simple. Thanks!

My ipod was stolen, can I find out what the serial number of it is, based on looking at a connection history in my itunes? How would I do this? I didn't register it.

My ipod was stolen, can I find out what the serial number of it is, based on looking at a connection history in my itunes? How would I do this? I didn't register it. I think I found the guy selling it, just looking to confirm the serial number and I'll make a phone call to the police.
Thanks

Yes.
Open iTunes on the computer you used to sync the iPod and select Preferences… from the iTunes menu.
Select the Devices pane. Position the cursor over any of its backups. The iPod's serial number will appear in a popup window.
