a simple solution

Hi,

You can try something like this

SELECT count(*),name from TEST group by name having count(test)>3;

Rgds,
Aashish S.

Thanks Nicloei ofr ur help

I have more than 1000 rows like that and many more to come.So that query will not be feasible i think.Thank u once agin
479546
Thanks Aashish

But the test no is not in order in exact case
NicloeiW
so use that query and modify your query for 100, 1000 or 10000 rows,,,,
479546
Thanks

You mean to write the 1000 names like tht
526547

What do you mean?

I think Aashish solution is correct. A slight variation if "names can retake tests"

select name, count (distinct testno)
from   <yourtable>
group  by name
having count( distinct testno) = <no. of tests>

In your example, no. of tests will be 4.

NicloeiW
Thanks

You mean to write the 1000 names like tht

omg ??? this is silly question ??

use table name, in my query instead of t,
and use column name from that table

or i should tell you that also ??

a more generic solution...

with t as  (
  select 1 slno, 'reni' name, 1 testno from dual union all
  select 2, 'arun', 2 from dual union all
  select 3, 'jithu', 3 from dual union all
  select 4, 'rajesh', 4 from dual union all
  select 5, 'shiju', 1 from dual union all
  select 6, 'Thomas', 1 from dual union all
  select 7, 'Thomas', 2 from dual union all
  select 8, 'Thomas', 3 from dual union all
  select 9, 'Thomas', 4 from dual 
)
select *
from (
  select t1.*, sys_connect_by_path(testno,'/') path
  from ( select t.*, lag(slno) over(partition by name order by testno) slno_lag from t ) t1
  start with slno_lag is null connect by slno_lag = prior slno
)
where path like '%/' || to_char(1) || '/' || to_char(2) ||
                '/' || to_char(3) || '/' || to_char(4)

just modify the where clause to match your criteria.
note: not tested for performance.

Many ppl have given you solutions and suggestions. Did you try those?

Anyway, check whether this helps or not?

When you try dont include the WITH clause. Since we dont have ur table and data, we showed an example with subset of data. Also change the "t" with yout table name and try. Solutions should work provided you try the proper query
NicloeiW
well i guess that to much of spoon feeding ;-)

i am not sure if he is trying that or not ?
474126
Nothing wrong in helping. Seems he is desperate for the help.
Does helping going to harm us? :-)
NicloeiW
no..
everyone needs help , it doesnt harm us, but if he cant use the query with as given to him, then i guess he should put an effort, like this he can learn better, 4 solutions are given to him,

that would benefit him in long run

Hi Mohan,

I think these solution won't work if any person has attampted more than once for a single test.

SQL> select * from t;

      SLNO NAME       TESTNO
---------- ------ ----------
         1 reni            1
         2 arun            2
         3 jithu           3
         4 rajesh          1
         5 shiju           1
 6 Thomas 1
7 Thomas 2
8 Thomas 3
9 Thomas 1

9 rows selected.

SQL> ed
Wrote file afiedt.buf

  1  select slno,name,testno
  2  from
  3   (select slno,name,testno,count(1) over(partition by name) cnt from t)
  4* where cnt =4
SQL> /

    SLNO NAME TESTNO
---------- ------ ----------
9 Thomas 1
6 Thomas 1

So the modified version of your query would be:

  2  SELECT slno,name,testno, count(1) OVER (PARTITION BY NAME ORDER BY NAME) cnt

  5  from
  6   (select slno,name,testno,
  7    ROW_NUMBER() OVER(PARTITION BY NAME, TESTNO ORDER BY NAME) RN
  8   from t)
  9  where RN =1
 10* )) WHERE cnt=4

If that was not unique on combining name and testno, then it gets wrong results.
But, you have goot point.

There is an elegant and (of course) mathematical solution... try

select name, sum(testno) from tests_record group by name having sum(testno) >= (1+2+3+4+...+n)

n = whatever the number of tests have been applied
n=2 s=3, n=3 s=6, n=4 s=10, n=5 s=15, n=6 s=21...

hope it helps

OP has requirement of finding whether all the tests have been attempted. Your solution will return result if student attempts any one of 1,2,3,4
587012
Hi,

This will work for you

select name,count(testno) from <table name>
group by name
having count(test)=4
587012
Hi,

Or u can try this for detail

select name,test
from xx
where name in (select name
from xx
group by name
having count(test)=4
)
order by name,test
1 - 23
