Is "01:00" a string format or an elapsed time format?
The number that the above code returns is decimal hours. So a number value of 1.5 means 1h30m or 1:30 or however you need to render that.
And that is the question. Is this a rendering issue? Must the result be rendered in a specific format?
If so, then this is not a SQL or PL/SQL issue. The server returning decimal hours is acceptable. The client (e.g. C#/Java code) needs to decide how to format and render this meaningful value. Keep in mind that if the sever code returns "1.30" or "1:30" for example, these are string/text data and pretty much meaningless. And it does not make sense for server code to return meaningless text strings to the client.
If the client expects a duration and not a numeric data type, then the server code should return a value of the INTERVAL DAY TO SECOND data type.
This data type specifically exists to contain duration values between to dates or times.
In this case, the server code will expect the host (C#/Java) variable to be of data type INTERVAL DAY TO SECOND. The server code will look something as follows:
SQL> declare
2          earlyleavers    interval day to second;
3 begin
4          earlyleavers := NumToDSinterval(
5                                  (to_date('1900/01/01 11:00:00','yyyy/mm/dd hh24:mi:ss') -
6                                  to_date('1900/01/01 10:00:00','yyyy/mm/dd hh24:mi:ss') ) * 24,
7                                  'hour'
8                          );
9
10          dbms_output.put_line( to_char(earlyleavers) );
11 end;
12 /
+00 01:00:00.000000
PL/SQL procedure successfully completed.
SQL>An interval-to-string conversion function is used (with default formatting) to "print" the interval value via DBMS_OUTPUT. The default format includes days and a sign to indicate a positive or negative interval. Look at the SQL Reference manual for the format masks that can be used.
The important thing is to treat data values correctly using the most appropriate type. And intervals should either be a decimal day/hour/minute numeric type, or an actual interval type.

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 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 named query if we want to use IN syntax in our sql statement?

I cannot find a suitable category about named query, so please move to appropriate place if there is any.
When we write named query, below statement is fine.
Query q2 = em.createQuery("SELECT o FROM Table1 as o WHERE field1 = :input1");             q2.setParameter("input1", "value1");
Now, my question is, how can I write this type of query when we want to use the IN sql syntax? As below statement CANNOT return correct results. Even I tried to put a pair of single quote [ ':input2' ], it won't help also.
Query q2 = em.createQuery("SELECT o FROM Table1 as o WHERE field2 IN (:input2)");             q2.setParameter("input1", "3633, 3644");
Can anyone suggest? Thanks.

Can anyone suggest?The above is in your code right? Not in some configuration file?
Then you do it the same way as with regular jdbc/sql.
1. You start with a collection of values - call it collection A.
1. Create a for loop that dynamically creates the string using 'bind' variables (whatever you want to call the 'colon' entity in the above).
2. Call the createQuery method using the string that was created
3. Create a second loop that iterates over A and populates with setParameter.
Pseudo code
        Object[] A = ...
        String sql = "SELECT o FROM Table1 as o WHERE field2 IN (";
        for (int i=1; i <= A.length; i++)
              if (i == 1)
                 sql += ":input" + i;
             else
                 sql += ",:input" + i;
        sql += ")";
        Query q2 = em.createQuery(sql);
        for (int i=1; i <= A.length; i++
              q2.setParameter("input" + i, A[i-1]);
              }By the way there is a jdbc forum.

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

Crystal Report XI: Can you write your query in SQL instead of using the GUI

Hello
In crystal report version XI, can you write your query in sqlplus and then use the crystal report designer to build your report instead of using the GUI . I would like to be able to go database and show sql query and open that query and make changes directly there, is that possible on this version, if yes is there a setting somewhere? Please let me know.
Thank you

Moved to Database forum.
No you can no longer modify the SQL directly. Use a Command Object to enter the SQL directly.

Assuming you're using SQL Server you can ask here:
http://www.sqlteam.com/forums/forum.asp?FORUM_ID=23
Otherwise, please ask in the relevant forum for the type of technology you're using.
Basically it's either:
select *
from [table name]
order by country
If you want to do something with groups do something like:
select (max) income, country
from [table name]
group by country

How to write workflow rules/expressions/SQL

Hi all.
We are recent users of CRM onDemand, we would like to write some workflow rules but cannot seem to find any information on how to do this. The help section is limited in answers, and some of the questions here are also not specific to what we would like to do.
Does anyone have any advice on books, web sites, etc. on where to find the knowledge we need on how to write the workflow rules and use SQL and expressions in CRM on Demand?
Thanks in advance!!

For your first case:
1. You cannot create a workflow in r15 for activity but in R16 you can
Create new to create a workflow
Name: Auto email send
record type: activity
trigger: when new record saved
rules: put your rules by clicking on the fx icon i.e this is where you are entering the rule saying the owner is different from the person who is creating the activity or the delegated field is filled (another way of looking at it)
then save the workflow
In the actions section
choose the action "Create Email Notification"
In the To: Section choose "Relative User on Record" and Choose "Activity Owner"
Save it. Make sure both the workflow and activity are marked active.
2. In your second scenario:
How do you expect to create an account and automatically populate the Sales rep's name - not sure
But you can create an opportunity and auto fill with the Account Owner's name by using this in the field validation (you do not need the workflow), you can use the FieldValueJoin function.
Hope this helps - btb there is no book you can go thro the help and you will find some directions
