How to select a row from duplicate set of records?

I want to select a row from a duplicate set of records.
below is the explanation of my requirement.
select * from test_dup;
COL_BILL     COL_SERV     COL_SYS
b1     s1     c
b1     s1     g
b1     s2     c
b1     s2     g
b2     s2     g
b2     s3     c
b2     s3     g
b3     s3     c
Here what I want is, for a distinct col_sys if col_bill and col_serv is same then I need the row where col_sys='c'
from the above result set I need the following:
b1     s1     c
b1     s2     c
b2     s3     c
I am using the following SQL query which is giving me the correct result set. But it will hamper the performance because there are total 45 columns in the table and total volume is around 50 million.
select * from test_dup where col_bill||col_serv in (
select col_bill||col_serv from (
select col_bill,col_serv,count(*) from test_dup
where col_sys in ('c','g')
group by col_bill,col_serv having count(*) >1)) and
col_sys='c';
Can anyone please provide me the optimize SQL query for the same.

Hi,
Another way,
SQL> with test_dup
as
     select 'b1' col_bill, 's1' col_serv, 'c' col_sys from dual union all
     select 'b1', 's1', 'g' from dual union all
     select 'b1', 's2', 'c' from dual union all
     select 'b1', 's2', 'g' from dual union all
     select 'b2', 's2', 'g' from dual union all
     select 'b2', 's3', 'c' from dual union all
     select 'b2', 's3', 'g' from dual union all
     select 'b3', 's3', 'c' from dual
select col_bill, col_serv, min(col_sys) col_sys
    from test_dup
   where col_sys in ('c', 'g')
group by col_bill, col_serv
having count( * ) > 1
     and count(nullif(col_sys, 'g')) > 0;
CO CO C
b1 s1 c
b2 s3 c
b1 s2 c
3 rows selected.Regards

Selecting all columns from table in a model query

I have written a model query which joins 4 tables, applies some rules and returns updated rows by selecting 4 columns out of this. Currently it works fine because all 4 columns are from MODEL aliases. Now I need to select 16 more columns in the same query but none of these columns is added in MODEL aliases. When I tried selecting these columns I got oracle error ORA - 32614. Can someone please guide me to include these columns in the same model query?
I tried couple of options but no luck. Here are those options for ready reference:
1. I cannot nest existing model query into another select because there are no columns avaiable to join in output of current query to map with other records.
2. I cannot include all 16 columns in MODEL aliases because some of these columns are actually output of user defined functions.
I am using Oracle database version 11g Release 11.2.0.1.0.

Thank you Avijit for your reply. There is a syntax error on the ON in this part of the statement which I don't know how to fix - I tried messing around with another INNER JOIN but am not confident that I'm doing the right thing:
SENAlertType.SENAlertTypeIDONClassMember.ClassMemberStudentID
Thanks for your help! I will need to do some more bedtime reading on joins.

Need help using Select statement to retrieve one record

Hi guys, my first post so be gentle please. The basis of this fucntion is to search my dtabase using the select statement to find the record the user wants, by retrieving the name of theitem from the text box. details are then displayed on a joption message box.
Everytime I run this program it throws an exception 'Exception: null'. Can anyone see where I am going wrong, I have only bn learning java for thepast 6 months so perhaps I am doing something wrong.
Or perhaps there is another way for me to close the st, con, rs?
Your help appreciated
public void searchproducts(){
Connection con = null;
Statement st = null;
ResultSet rs = null;
try{
//creating and loading a database connection
String dbUrl = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=db2.mdb;"; // String dbUrl = "jdbc:odbc:people";
String user = "";
String password = "";
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection c = DriverManager.getConnection(
dbUrl, user, password);
int count;
st = con.createStatement();
rs = st.executeQuery("SELECT ItemName, Country, Yearmade, ValuePrice, Forsale FROM Collectman WHERE ItemName="+" '"+txtsearchproduct.getText()+"'" );
while(rs.next()) {
String ItemName = rs.getString(1);
String Country = rs.getString(2);
String Yearmade = rs.getString(3);
String ValuePrice = rs.getString(4);
String Forsale = rs.getString(5);
JOptionPane.showMessageDialog(null, "product details are: " + ItemName + " " + Country + " " + Yearmade + " " + ValuePrice + " " + Forsale);
//It keeps on throwing this excpetion with null
catch (Exception e) {
System.err.println("Exception: " + e.getMessage());
} finally {
try {
if(rs != null)
rs.close();
if(st != null)
st.close();
if(con != null)
con.close();
} catch (SQLException e) {
}

And while we're waiting on that, I'll just say it's nice to see you almost got the general layout of a db call correct...that's a rare thing around here. The finally should have a try/catch round each of the close statements and not around all three in one go. If the resultset throws an exception in your version then you would fail to close either the statement or the connection.
The second thing is, look up PreparedStatements. They're a better choice for handling SQL requiring variables than using a bog standard Statement.

Select LONG column from Remote table

Hi to all.
I have the following problem: I can't select a LONG column from remote database, when there are Join operation in the query. Example:
SELECT long_column FROM remote_table@DB
-> that's OK, but:
SELECT long_column FROM remote_table@DB INNER JOIN remote_table2@DB ON ...
-> returns: "ORA-00997: Illegal use of LONG datatype"
I cannot even perform (because there a LONG column in the joined table):
SELECT nonlong_column FROM remote_table@DB INNER JOIN remote_table2@DB ON ...
That's very strange to me because:
SELECT long_column FROM local_table INNER JOIN local_table2 ON ...
-> is OK!
Can someone help me to SELECT a long column from remote in SELECT query with JOIN clause!
Thanks a lot!

Hi
"Distributed queries are currently subject to the restriction that all tables locked by a FOR UPDATE clause and all tables with LONG columns selected by the query must be located on the same database. " by otn docs.
I have no idea.

Select sql running very long when made to select many columns from a table

Hi,
I am using an Oracle DB 10g. I have a table with 250 columns and I need to select 200 columns out of them. The table holds around 0.1 million rows. But when I run the select sql it takes 15 mins to return .1 million rows. Where as if I select only 10 or 15 columns the sql runs in less than a minute returning same number of rows. My sql looks like below:
select p.col1,p.col2,.......,p.col200
from table Parent p;
The table also has a Primary key Index but it does not seem to be using it even when I forced an Index hint. Could you pls help?

As Sven points out, it is likely that most of your time is network (and client) time. You are sending 20 times as much data (based on column counts, at any rate) across the network, and concerned that it's taking 15 times as long.
If you're testing from SQL*Plus then setting the arraysize to a value larger than the default might help.
If you have control over the SQL*Net settings then you may get some benefit by adjusting the SDU sizes at both ends of the link.
If you have control over the tcp configuration (transmit and receive buffer sizes) then you may get some benefit by adjusting these.
Simple test, by the way, if you're on SQL*Plus
set autotrace traceonly statistics
select ...This will dump your data in the bit bucket as it arrives giving you
a) the database time plus network time
b) some statistics including the volume of data down the network and the number of network round-trips that Oracle saw.

How to create a LookUp field, selecting a value from another record type ??

Hello all,
I am looking to create a new field in Opportunity in CRM On Demand where we can give the user an option to select one of the records. Data in this search applet should come from another Record Type in CRM On Demand. I am not able to find any similar literature in the Help books.
I would appreciate if somebody could give me real life steps please.
Thanks a lot

Okay. I found the solution to this.
Now, along with this single reference, we also wish to bring the values of some more joined fields from the other record type in the Opportunities screen.
We were hoping that the Default value, and using fx, we should be able to achieve this using "joinedfieldvalue". However, it's not bringing back any value. Our expression is -
JoinFieldValue('<CustomObject3>',[<CustomObject3Id>],'<stState_ITAG>')
Please help if you have done this before.
Thanks & Regards

[10g] Simple question on selecting a column in same record as a min value

I have the following sample data to illustrate my question:
CREATE TABLE     t_1
(     c_a     VARCHAR2(1)
,     c_b     NUMBER(2)
,     c_c     DATE
INSERT INTO     t_1
VALUES('A',1,SYSDATE);
INSERT INTO     t_1
VALUES('A',2,SYSDATE+1);
INSERT INTO     t_1
VALUES('A',3,SYSDATE+2);
INSERT INTO     t_1
VALUES('A',4,SYSDATE+3);
INSERT INTO     t_1
VALUES('B',3,SYSDATE+6);
INSERT INTO     t_1
VALUES('B',4,SYSDATE+7);
INSERT INTO     t_1
VALUES('B',5,SYSDATE+8);I have the following query which allows me to select the value of c_c that corresponds with the minimum value of c_b grouped by c_a. In other words, my goal is: for each value in c_a, I want the value of c_c that corresponds with the minimum value of c_b.
SELECT     t1.c_a
,     t1.c_c
FROM     t_1 t1
     SELECT      c_a
     ,      MIN(c_b)     AS min_c_b
     FROM      t_1
     GROUP BY c_a
     ) t2
WHERE     t1.c_a     = t2.c_a
AND     t1.c_b     = t2.min_c_b
;This query works, but I'm wondering if there is a more efficient way to do this. Something without a subquery? I can't come up with anything else... It just gets a bit ugly with my real data, as there are probably 10 columns of data instead of 3. (Still only 1 minimum value though).

Hi,
Since you're using Oracle 10, you can do this:
SELECT       c_a
,       MIN (c_c) KEEP (DENSE_RANK FIRST ORDER BY c_b)     AS c_of_min_b
FROM       t_1
GROUP BY c_a
;This won't work in earlier versions.
What do you want in case of a tie?
For example, if we add one more row to the sample data:
INSERT INTO     t_1 (c_a, c_b, c_c)
             VALUES ('A', 1,    DATE '2001-01-01');Now there are two rows, one dated today and one dated 2001, that have an equal claim to being the "first" in group 'A', since they have the exact same value of c_b.
The query above would display the row from 2001, that is, the earliest of the contenders. That's what MIN means in the query above. Instead of MIN, you can use any aggregate function, but, of course, that function has to work on your data type.
If you want to show all the contenders in case of a tie, then you can stick with your original query, or you could use the analytic RANK function.
WITH     got_rnk          AS
     SELECT     c_a, c_c
     ,     RANK () OVER ( PARTITION BY c_a
                           ORDER BY          c_b
                    )   AS rnk
     FROM    t_1
SELECT     c_a, c_c
FROM     got_rnk
WHERE     rnk     = 1
;This approach requires a sub-query, because analytic functions (like RANK) are computed after the WHERE clause is applied. If we want to use the results of an anlytic func tion in a WHERE clause, we have to compute the function in a suib-query first.

Selecting a column from a table conditionally

I'm trying this select statement (example):
select np.phone_number from name_phone np, reservation_general_view rgv
where rgv.resort='HVILLA'
In this table there is a column called "phone_type" and I only want my column to display values that are associated to the column when the "phone_type" = 'EMAIL'
I tried this:
select np.phone_number(select np.phone_number from name_phone np where np.phone_type='EMAIL')
from name_phone np, reservation_general_view rgv
where rgv.resort='HVILLA'
This doesn't seem to work...can someone tell me how to do that?

How do I create a Search Help which selects some rows from a table?

Well, I'm trying to be specific.
I have a parameter with a search help that shows columns BUKRS and BUTXT for ALL rows form the table T001. What I need is restrict the search help to show only three Values: BUKRS = 1000 BUKRS = 2000 BUKRS = 3000. This is like a search help with a SELECT sentence. How do I do it?

Hi.,
you can go through thomas sir's suggestion. But my suggestion is If you are working in a custom Report , dont change it at Table level or Domail Level., Instead, use Function Module for Custom F4 help.,
AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_bukrs.
CALL FM F4IF_INT_TABLE_VALUE_REQUEST.

Select a column from an inner select statement

On my oracle 10g running on solaris, I am running this little query that gives me
the right results (I needed one more column and not able to get to it, hence looking for some ideas here)
Select a.othtype, a.date_from, a.date_to,b.process
from bio_plan_other a,
bio b,
Where a.bkey = b.bkey
and a.date_from <
(Select min(f.edate)
from bio_service f
where f.bkey = a.bkey) ;
In the inner select table bio_service, I have an additional column called service_name. Hence for the min(f.edate), there is a corresponding service_name.
How do I get that service_name in my topmost SELECT statement ?
In other words, I wanted to do something like...
Select a.othtype, a.date_from, a.date_to,b.process,f.service_name
from bio_plan_other a,
bio b,
Where a.bkey = b.bkey
and a.date_from <
(Select min(f.edate)
from bio_service f
where f.bkey = a.bkey) ;
But this gives me,
ORA-00904 : f.service_name : invalid identifier
Thanks

Hi
Not knowing your datamodel, but you probably have more service names per date, so did you try this?
WITH t_bio_service AS (SELECT b2.bkey, b2.min_edate, b.service_name
                         FROM bio_service b
                            , (SELECT MIN(edate) min_edate, bkey
                                 FROM bio_service
                                GROUP BY bkey) b2
                        WHERE b2.bkey = b.bkey
                          AND b2.min_edate = b.edate)
SELECT a.othtype, a.date_from, a.date_to,b.process, t.service_name
FROM bio_plan_other a,
       bio b,
       t_bio_service t
WHERE a.bkey = b.bkey
   AND t.BKEY = b.bkey
   AND a.date_from < t.min_edateHope this helps.

Selecting only columns from a table

Could someone help me with a SQL query to select all the columns in a table as an array?

Hello
if you are on 9i upward, you can define a pl/sql table of the rowtype and use bulk collect to populate that table, otherwise, you can create separate array types for each column:
create table dt_test_tab (id number, col1 varchar2(10));
insert into dt_test_tab values(1, 'X');
insert into dt_test_tab values(2, 'X');
insert into dt_test_tab values(3, 'X');
insert into dt_test_tab values(4, 'X');
insert into dt_test_tab values(5, 'X');
commit;
declare
    type tt_TestTab is table of dt_test_tab%rowtype index by binary_integer;
    type tt_TestTabid IS TABLE OF dt_test_tab.id%type index by binary_integer;
    type tt_TestTabcol1 IS TABLE OF dt_test_tab.col1%type index by binary_integer;
    lt_TestTab     tt_TestTab;
    lt_Id          tt_TestTabId;
    lt_col1        tt_TestTabcol1;
begin
    --use the rowtype array
    select
         id,
         col1
    BULK COLLECT INTO

I don't know anything about Hibernate, but the reason why you need to specify the trunc(publish_date) = to_date('09/07/2007','dd/mm/yyyy') is because of the way that Oracle stores date/time internally.
It's labelled as a date field, but the time is automatically stored as well. So, if you're just wanting to compare the date to another date, you need to ignore the time part of the column - the trunc function does this.
As for the "to_date(<date>, <date mask>)", well, you want to compare a date to a date, not a string. You could rely on the implicit conversion, governed by the nls settings, but I really, really, really wouldn't. In fact, I can't stress enough how much of a bad idea that would be! It's best to make things explicit.
