How to write a query to get the total as a last row

Hi,
I need to get something like this ....
|TEAM LEADER| TEAM | OCT TRN | EMPS| YTD% |
|_____________|__________|__________|______|_______|
| JOHN | JD Team | 12 | 12 | 100 |
|_____________|__________|__________|______|_______|
| Total | | 12 | 12 | 100 |
|_____________|__________|__________|______|_______|
I have to get the last row as total adding the number columns ...
Thanks in advance ...

Take a look at the GROUP BY ROLLUP feature:
create table t1
(team_name      varchar2(30)
,wins           number
,losses         number
insert into t1 values ('Hornets',3,1);
insert into t1 values ('Panthers',4,0);
insert into t1 values ('Wolves',2,2);
insert into t1 values ('Badgers',0,4);
insert into t1 values ('Hornets',1,3);
commit;
select decode(team_name,
             NULL,'TOTAL',
             team_name) team_name, sum(wins), sum(losses)
from   t1
group by rollup(team_name);
TEAM_NAME                                 SUM(WINS)          SUM(LOSSES)
Badgers                                           0                    4
Hornets                                           4                    4
Panthers                                          4                    0
Wolves                                            2                    2
TOTAL                                            10                   10

How to write a query to get the time difference of two varchar type time columns

Hi,
I want to get the time difference between the two varchar type columns.please see the attached image for more details:
My requirement is like:
timestarted
timeended
timediff
9:00:00
10:00:00
1:00
9:15
9:30:00
0:15

Storing time alone as VARCHAR2 value is a incorrect design. Always store it as DATE or TIMESTAMP.
If you already have a messed up design and cant change it, then you need to convert your VARCHAR2 time into a DATE or TIMESTAMP and find the difference. I have converted it to TIMESTAMP and obtained the difference as INTERVAL.

How to modify this query to get the desired output format

I hv written a Query to display all the parent table names and their primary key columns(relevant to this foreign key of the child table).The query is given below...
SELECT DISTINCT(TABLE_NAME) AS PARENT_TABLE,COLUMN_NAME AS PARENT_COLUMN
FROM ALL_CONS_COLUMNS
WHERE CONSTRAINT_NAME IN (SELECT AC.R_CONSTRAINT_NAME
FROM ALL_CONSTRAINTS AC
WHERE AC.TABLE_NAME=TABLE_NAME
AND AC.TABLE_NAME='&TABLE'
AND AC.R_CONSTRAINT_NAME IS NOT NULL);
This query will display all the parent tables and their primary key columns.Now my problem is that how to modify this query to also display the foreign key column name of the child table.
I want the query result in the following format.The query should display the following columns.1)child table's name,2)child table's foreign key column name,3)the corresponding parent table's name,4)the parent table's primary key column name(which is the foreign key in the child table).
For Example I want the output as follows...
TAKE THE CASE OF SCOTT.EMP(AS INPUT TO YOUR QUERY)
CHILD_TABLE CHILD_COLUMN PARENT_TABLE PARENT_COLUMN
EMP DEPTNO DEPT DEPTNO
In this result I hv used alias name for the columns.The query should display this only for the foreign keys in the child table.In the query which I sent to you earlier will give the parent table and the parent column names,But I also want to append the child table and child column names there.
any help on how to tackle would be appreciated.

Try this query
SELECT c.table_name child_table,
     c.column_name child_column,
     p.table_name parent_table,
     p.column_name parent_column
FROM user_constraints a,user_constraints b,user_cons_columns c,
     user_cons_columns p
WHERE a.r_constraint_name=b.constraint_name and
      a.constraint_name=c.constraint_name and
      b.constraint_name=p.constraint_name and
      c.position=p.position
ORDER BY c.constraint_name,c.position

How to write SQL query to flatten the hierarchy

Hi,
I have person table which has recursive hierarchy and I wish to flatten it upto 5 levels.
I am using Oracle10g and I have written following query to flatten the hierarchy
SELECT
ID,
level lvl,
REGEXP_SUBSTR (SYS_CONNECT_BY_PATH (fname||' '||lname, '/'), '[^/]+', 1, 1) AS level_1,
REGEXP_SUBSTR (SYS_CONNECT_BY_PATH (fname||' '||lname, '/'), '[^/]+', 1, 2) AS level_2,
REGEXP_SUBSTR (SYS_CONNECT_BY_PATH (fname||' '||lname, '/'), '[^/]+', 1, 3) AS level_3,
REGEXP_SUBSTR (SYS_CONNECT_BY_PATH (fname||' '||lname, '/'), '[^/]+', 1, 4) AS level_4,
REGEXP_SUBSTR (SYS_CONNECT_BY_PATH (fname||' '||lname, '/'), '[^/]+', 1, 5) AS level_5
FROM cmt_person
CONNECT BY manager_id = PRIOR id
and level<=5
The person table have more than a million records.
Here I am getting the correct output but this query is taking a lot of time to run.
I am looking at a SQL query without use of connect by to get the required output.
To recreate the issue, you can use this query in HR schema of Oracle and use Employees table.
Any help would be greatly appreciated.
Thanks,
Raghvendra

I tried to rewrite the query without using regular expression and connect by. Here is the code:
SELECT
cmt_person.id ,
cmt_person.fname as mgr1,
case when cmt_person2.manager_id=cmt_person.id then (cmt_person2.fname ) end as mgr2,
case when cmt_person3.manager_id=cmt_person2.id then (cmt_person3.fname ) end as mgr3,
case when cmt_person4.manager_id=cmt_person3.id then cmt_person4.fname end as mgr4,
case when cmt_person5.manager_id=cmt_person4.id then cmt_person5.fname end as mgr5
FROM
cmt_person,
cmt_person cmt_person2,
cmt_person cmt_person3,
cmt_person cmt_person4,
cmt_person cmt_person5
WHERE
cmt_person2.manager_id(+)=cmt_person.id and
cmt_person3.manager_id(+)=cmt_person2.id and
cmt_person4.manager_id(+)=cmt_person3.id and
cmt_person5.manager_id(+)=cmt_person4.id
order by 2,3,4
I got following output:

sorry if i didn't make this clear.
here is the problem. i have three tables. like below. i also give some sample data
USERS, USER_MAX_LOGIN, EXCEPTION_USER
USERS table has all the user information for each user in each database.
USER_MAX_LOGIN has those users who logged in within 1 year (we keep 1 year audit data)
EXCEPTION_USER has user which should be excluded from the report.
My report need to find all users in all databases who has not logged in for more than 90 days.
USERS
username     target_db     profile
u1     d1     user
u2     d1     user
u3     d2     user
u1     d2     user
u2     d2     user

u2     d2     06-Sep-11
EXCEPTION_USER
username     target_db
u2     d1
THIS IS THE REPORT I NEED TO BE LOOK LIKE.
username     target_db     last_login     profile

u2     d2     06-Sep-11     user
u3     d1     UNKNOWN     user <<----- the unknown means we don't know when the user logged in last time. the user_max_login table does not have its information.

How to run this query to get the minutes between two hours?

Hi all,
Hope doing well,
sir i am running one query which is:
v_TotalHrsMin1 := LPAD((extract(minute from TO_TIMESTAMP (v_Temphrs,'HH24:mi:ss')) - extract(minute from TO_TIMESTAMP (v_Outtime1,'HH24:mi:ss'))), 2, '0');--select to_date(v_temphrs,'YYYY-MM-DD HH:mi:ss')-to_date(v_OutPunch,'YYYY-MM-DD HH:mi:ss')*1440;
in this v_TotalHrsMin1 is number datatype and v_Temphrs is varchar2 which is storing this value: 12:00:00
and v_Outtime1 is varchar2 which is storing 06:00:00
now i want the minute difference between both times
and insert into v_Totalmin1.
but getting null value in v_totalmin1.
thanks

Hi Sir,
i used query like this: v_TotalHrsMin1 := extract(hour from time_interval) * 60 + extract(minute from time_interval) from (select to_timestamp(v_temphrs,'HH24:MI:SS')-to_timestamp(v_outtime1,'HH24:MI:SS') time_interval from dual);That is not a query - that is a PL/SQL assignment expression. You should learn the differences between SQL and PL/SQL and how they work together ;-)
When doing it in PL/SQL, you do not need a query at all. Why would you do a select from dual in the PL/SQL assignment.
But you should be able to take the SQL example I gave you and write the equivalent PL/SQL code.
We do not want to do your work for you - we want to teach you how to do it yourself.
You should try and understand the examples we give you - not just cut-and-paste it and cry for help when you are cut-and-pasting a SQL example into PL/SQL code.
Anyway - here's a way to do it in PL/SQL:
declare
   v_outtime1 varchar2(8);
   v_temphrs   varchar2(8);
   v_interval interval day to second;
   v_totalhrsmin1 number;
begin
   v_outtime1 := '06:00:00';
   v_temphrs := '12:00:00';
   v_interval := to_timestamp(v_temphrs,'HH24:MI:SS')-to_timestamp(v_outtime1,'HH24:MI:SS');
   v_totalhrsmin1 := extract(hour from v_interval) * 60 + extract(minute from v_interval);
end;
/What's so difficult about taking my SQL example, understanding what the differenct functions do, and then write that piece of PL/SQL? ;-)

How to write select query for all the user tables in database

Can any one tell me how to select the columns from all the user tables in a database
Here I had 3columns as input...
1.phone no
2.memberid
3.sub no.
I have to select call time,record,agn from all the tables in a database...all database tables have the same column names but some may have additional columns..
Eg: select call time, record,agn from ah_t_table where phone no= 6186759765,memberid=j34563298

Starting in Oracle 10, you can also use Q-notation:
http://download.oracle.com/docs/cd/E11882_01/server.112/e17118/sql_elements003.htm#i42617
...and also can you tell me how to execute the output of this script. What front end are you using? If it's SQL*Plus, then you can SPOOL the query to a file, and then execute that file, like this:
-- Suppress SQL*Plus features that interfere with raw output
SET     FEEDBACK     OFF
SET     PAGESIZE     0
-- Run preliminary query to generate main query
SPOOL     c:\my_sql_dir\all_ah_t.sql
SELECT       'select call time, record, agn from '
||       owner
||       '.'
||       table_name
||       ' where phone_no = ''6186759765'' and memberid = j34563298'
||       CASE
           WHEN ROW_NUMBER () OVER ( ORDER BY owner          DESC
                          ,        table_name      DESC
                          ) = 1
           THEN ';'
           ELSE ' UNION ALL'
       END     AS txt
FROM       all_tables
WHERE       SUBSTR (table_name, 1, 4)     = 'AH_T'
ORDER BY owner
,       table_name
SPOOL     OFF
-- Restore SQL*Plus features that interfere with raw output (if desired)
SET     FEEDBACK     ON
SET     PAGESIZE     50
-- Run main query:
@c:\my_sql_dir\all_ah_t.sql
so that i form a temporary view for this script as a table(or store the result in a temp table) and my problem will be solved..Sorry, I don't understand. What is a "temporary view"?

qrygroup1 is item property 1, qrygroup2 is item property 2 etc.

How to get the total amount of filtered row in a table view

I have created filter tables for each columns of my tableview. Now I want to add a row with some totals. For this I use an iterator and implement the RENDER_ROW_START. It is easy to add a new lines knowing the number of expected rows (add the line at the end). But the hic comes when there is a filter. How can I know how many rows I will have in the filtered table. There is no parameters that I found. Not even in an event handler.
Thanks a lot in advance for your help

i found the solution, thanks

Query to get the data of all the columns in a table except any one column

Can anyone please tell how to write a query to get the data of all the columns in a table except one particular column..
For Example:
Let us consider the EMP table.,
From this table except the column comm all the remaining columns of the table should be listed
For this we can write a query like this..
Select empno, ename, job, mgr, sal, hiredate, deptno from emp;
Just to avoid only one column, I mentioned all the remaining ( 7 ) columns of the table in the query..
As the EMP table consists only 8 columns, it doesn't seem much difficult to mention all the columns in the query,
but if a table have 100 columns in the table, then do we have to mention all the columns in the query..?
Is there any other way of writing the query to get the required result..?
Thanks..

Your best best it to just list all the columns. Any other method will just cause more headaches and complicated code.
If you really need to list all the columns for a table because you don't want to type them, just use something like...
SQL> ed
Wrote file afiedt.buf
1 select trim(',' from sys_connect_by_path(column_name,',')) as columns
2 from (select column_name, row_number() over (order by column_id) as column_id
3        from user_tab_cols
4        where column_name not in ('COMM')
5        and   table_name = 'EMP'
6       )
7 where connect_by_isleaf = 1
8 connect by column_id = prior column_id + 1
9* start with column_id = 1
SQL> /
