Needs help in writing an sql.

Hi Gurus,
Here is my sql
select c.owner,c.table_name, c.num_rows,(c.num_rows-t.num_rows)"ROW_DIFFERENCE"
from scms_tabs c,eosenv35_tabs@demoeos t where c.num_rows-t.num_rows >0
i have 164 tables in both the tables scms_tabs and eosenv35_tabs@demoeos which has data num_rows>0
but when i run the query it fetches 124762 rows.
any expert suggestion on this is highly apprciated
Thanks in advance

Thanks for the reply .
Both the tables are the same just that they are on two different database.
i just need to find the records which has difference in the row_num from both the tables.
demoeos is a dblink.

Need help to writing a sql

Hi all,
I have a table with 2 fileds, say Patch , Applied_date
Example table is below:
Patch      Applied_date

222     1-Feb-10
333     1-Mar-10
444     2-Jan-10
555     1-Jan-12
666     3-Jan-10
I want a query to display output like below.
say i query for " where patch in (111,222,777,888)"
i expect the output to be
patch Applied_date
================
111 1-Jan-10
222     1-Feb-10
777 Not applied *** since 777 is not in the table , i want the applied date to be displayed a not applied ***
888 Not applied *** 888 column dosent exist in the table, even then i want it in the result and its
corresponding column(Applied_date) to be Not applied.
Can someone write a sql for this.
I can write a PL/SQL . I want an sql.
Thanks,
Prasad

Create patch list as a table and use outer join:
with patch as (
               select 111 patch,to_date('1-Jan-10','dd-mon-rr') applied_date from dual union all
               select 222,to_date('1-Feb-10','dd-mon-rr') from dual union all
               select 333,to_date('1-Mar-10','dd-mon-rr') from dual union all
               select 444,to_date('2-Jan-10','dd-mon-rr') from dual union all
               select 555,to_date('1-Jan-12','dd-mon-rr') from dual union all
               select 666,to_date('3-Jan-10','dd-mon-rr') from dual
     list as (
               select 111 patch from dual union all
               select 222 from dual union all
               select 777 from dual union all
               select 888 from dual
select l.patch,
        nvl(to_char(p.applied_date,'dd-Mon-yy'),'Not applied') applied_date
from      patch p
        right join
            list l
          on l.patch = p.patch
     PATCH APPLIED_DAT
       111 01-Jan-10

Try using format part of the JSTL tag libs.

Need help for writing extract program

hi
i need help for writing extract program to retriew data from legacy system.
i already developed bdc programs for me31k and me21.
my requirement is to write extract program s for those t.codes.
to retriew data from legacy system and stored in flat file.

i need help with a java program. it is a program that allows the user to enter a student's GPA, number of extracurricular activities, and number of service activities. The user can not enter a gpa above 4.0 or below 0. The user can not enter a negative number for the number of both activities. If the student meets the following criteria: 1) GPA of 3.8 or above and at least one extracurricular activity and one service activity, 2) GPA below 3.8 but at least 3.4 and a total of at least three extracurricular and service activities, 3) GPA below 3.4 but at least 3.0 and at least two extracurricular activities and three service activities, the message "Scholarship candidate" should display. If the student does not meet the criteria above, then the message"not a candidate" should display. Can you help me, please?
You haven't posted ANY 'java program' for us to help with.
The forum is NOT a coding service. It is to help you with YOUR code.
Post the code you have written and SHOW us (don't just tell us) how you compile it and execute it and the results you get. Then we can help you with any problems you are are having.
If you need help understanding just what the program should be doing you need to ask your instructor to clarify the assignment.

Need Help in writing a UDF

Hi,
Please help in writing a UDF for these fields in mapping, which I need for the object Iu2019m doing currently.
The fields are like this:
1)         batch_no = "TRUNC((GetMaxObjid('x_txn_sap_parts')-POWER(2,28))/5000)+1",
2)         lot_id = "TRUNC((GetMaxObjid('x_txn_sap_parts')-POWER(2,28))/500)+1",
3)        How to use JDBC connection factory class in the UDF.
Some logic I can provide which I know i.e. Power (2, 28) means 2 to the power of 28 (2 multiplied 28 times), Trunc means truncate, X_TXN_SAP_Parts is a database table.The Target fields are Batch_no, lot_id & Objid.Actually, objid is mapped initially to a source field i.e. Object ID and in this function it is only being used for the calculation of the batch_no.
Thanks in Advance,
Sreedhar.

Hi,
Following with my query I've tried to use this code but still I'm unable to execute the mapping.
import java.util.*;
import com.sap.aii.mapping.lookup.*;
import com.sap.aii.mapping.lookup.*;
DataBaseAccessor accessor = null;
DataBaseResult JDBCOutPayload = null;
String BusinessSystem="clarify_dev_bizsys";
//give your business system having channel name
String CommunicationChannel="JDBC_TO_CDEV";
//give your channel name
String InputPayload= " select X_TXN_PRE_SITE_XFACE.nextval from dual;";
//give your sql query
try {
Channel channel =
LookupService.getChannel(BusinessSystem,CommunicationChannel);
accessor = LookupService.getDataBaseAccessor(channel);
DataBaseResult resultSet = accessor.execute(InputPayload);
     for(Iterator rows = resultSet.getRows();rows.hasNext();){
     Map rowMap = (Map)rows.next();
     Object cValue = rowMap.get("batchno");
//field name of field required , as in database
      catch (Exception e) {}
      finally {
              if (accessor != null)
              accessor.close();
       result.addValue((String)cValue);
--> I don't know what are the parameters to be used and how to be used in the UDF because this is the first time I'm writing a UDF.
--> The problem in using this query is that both OBJID & BatchNo. are on the target side and the value for the OBJID is retrieved by a SELECT query from the database.
Kindly help me how to resolve this query of mine.
Thanks in Advance.
Sreedhar.

Need help in writting the sql

The sql
select 'alter system kill session '||sid||','||serial#||';' from v$session where username= 'EV05';
give the output in the below given form
alter system kill session 69,38769;
But i need the output to be
alter system kill session '69,38769';
Can some one re-writes the sql select statment,
Thanks
Naveen

Naveen,
This isn't the forum for help with writing SQL - rather with using the SQL Developer product. In future, I would suggest that you use the SQL and PL/SQL forum for these sorts of questions.
However, to answer your question this time, you can include a ' in a string by having two together ie 'fred''s' will return the string fred's.
The following SQL will give you the result you want:
select 'alter system kill session '''||sid||','||serial#||''';' from v$session where username= 'EV05';

Need help in rewriting a sql query

Can any one please tell me if there is any utility that can help me correcting the sql I have I need to tune the query as its taking lot of time. I want to use some tool that will help me re-formating the query.
Any help in this regard will be highly appreciated.

If you think that Oracle SQL Tuning Tools like SQL Tuning Advisor and SQL Access Advisor are not helping.
You might look into thrid party tools like Quest- SQL Navigator and TOAD.
But I don't advise this based on the following:
Re: Oracle Third Party Tools and Oracle Database
Oracle have enough tools of its own to satisfy the various needs.

Need help to redesign legacy SQL Script

Hello Experts,
I have the below code which produces a CREATE TRIGGER statement. as of now this does for updating. I need to re-design this code to add for inserting and deleting as well. I just need help in the structuring wise. I can build the logic for inserting and updating inside. I want to know how i can continue to get for "inserting" and "deleting" as well.
you will understand my question better if you go through main code, present output and required output format below.
I know this is a bad design first of all. but the below code is a legacy one. so i cant change the entire structure of the code :-( all i can do is to continue designing it to add new changes. Hence sought help from you all.
please help

Help on writing pl/sql stored procedure to accept input in xml format

Hi All,
I need to write a pl.sql stored procedure which would be getting the input as an xml.
The requirement is that xml data recieved in below fashion needs to be inserted to 3 different tables.
The tags under the root node directly needs to be inserted into Table1
The tags under the first element of the root node needs to be inserted into Table2
Can anybody help me on how to write a stored procedure which could take up the below xml as input and insert the data received into 3 different tables.
Any sample code.pointers to achieve this could be of great help.
The structure of the xml would be as follows:
<AssemblyProduct>
<AssemblyHeader>
<Name></Name>
<AssemblyId></AssemblyId>
<ListOfHCSIFFs><HCSIFFHeader><Id></Id> </HCSIFFHeader> </ListOfHCSIFFs>
<ListOfHCSIFFs><HCSIFFHeader><Id></Id> </HCSIFFHeader> </ListOfHCSIFFs>
<ListOfHCSIFFs><HCSIFFHeader><Id></Id> </HCSIFFHeader> </ListOfHCSIFFs>
</AssemblyHeader>
<AssemblyHeader>
<Name></Name>
<AssemblyId></AssemblyId>
</AssemblyHeader>
<AssemblyHeader></AssemblyHeader>
<ApplicationId></ApplicationId>
<ApplicationName></ApplicationName>
<ApplicationValidFrom></ApplicationValidFrom>
<ApplicationValidTo></ApplicationValidTo>
</AssemblyProduct>

Well you could write your procedure to accept a parameter of XMLTYPE datatype and then use that value in a query inside the procedure to break the data up as required using something like XMLTABLE e.g.
-- Nested repeating groups example:
WITH t as (select XMLTYPE('
<RECSET>
<REC>
    <COUNTRY>1</COUNTRY>
    <POINT>1800</POINT>
    <USER_INFO>
      <USER_ID>1</USER_ID>
      <TARGET>28</TARGET>
      <STATE>6</STATE>
      <TASK>12</TASK>
    </USER_INFO>
    <USER_INFO>
      <USER_ID>5</USER_ID>
      <TARGET>19</TARGET>
      <STATE>1</STATE>
      <TASK>90</TASK>
    </USER_INFO>
</REC>
<REC>
    <COUNTRY>2</COUNTRY>
    <POINT>2400</POINT>
    <USER_INFO>
      <USER_ID>3</USER_ID>
      <TARGET>14</TARGET>
      <STATE>7</STATE>
      <TASK>5</TASK>
    </USER_INFO>
</REC>
</RECSET>') as xml from dual)
-- END OF TEST DATA
select x.country, x.point, y.user_id, y.target, y.state, y.task
from t
    ,XMLTABLE('/RECSET/REC'
              PASSING t.xml
              COLUMNS country NUMBER PATH '/REC/COUNTRY'
                     ,point   NUMBER PATH '/REC/POINT'
                     ,user_info XMLTYPE PATH '/REC/*'
             ) x
    ,XMLTABLE('/USER_INFO'
              PASSING x.user_info
              COLUMNS user_id NUMBER PATH '/USER_INFO/USER_ID'
                     ,target NUMBER PATH '/USER_INFO/TARGET'
                     ,state   NUMBER PATH '/USER_INFO/STATE'
                     ,task    NUMBER PATH '/USER_INFO/TASK'
             ) y

Need help with writing a query with dynamic FROM clause

Hi Folks,
I need help with an query that should generate the "FROM" clause dynamically.
My main query is as follows
select DT_SKEY, count(*)
from *???*
where DT_SKEY between 20110601 and 20110719
group by DT_SKEY
having count(*) = 0
order by 1; The "from" clause of the above query should be generated as below
select 'Schema_Name'||'.'||TABLE_NAME
from dba_tables
where OWNER = 'Schema_Name'Simply sticking the later query in the first query does not work.
Any pointers will be appreciated.
Thanks

Remember that anything inside quotes is case-sensitive. Is the owner really "Schema_Name" with a capital S and a capital N, and 8 lower-case letters?
Simply sticking the later query in the first query does not work.Right; the table name must be given when you compile the query. It's not an expression that you can generate in the query itself.
Any pointers will be appreciated.In SQL*Plus, you can do something like the query bleow.
Say you want to count the rows in scott.emp, but you're not certain that the name is emp; it could be emp_2011 or emp_august, or anything else that starts with e. (And the name could change every day, so you can't just look it up now and hard-code it in a query that you want to run in the future.)
Typically, how dynamic SQL works is that some code (such as a preliminary query) gets some of the information you need to write the query first, and you use that information in a SQL statement that is compiled and run after that. For example:
-- Preliminary Query:
COLUMN     my_table_name_col     NEW_VALUE my_table_name
SELECT     table_name     AS my_table_name_col
FROM     all_tables
WHERE     owner          = 'SCOTT'
AND     table_name     LIKE 'E%';
-- Main Query:
SELECT     COUNT (*)     AS cnt
FROM     scott.&my_table_name
;This assumes that the preliminary query will find exactly one row; that is, it assumes that SCOTT has exactly one table whose name starts with E. Could you have 0 tables in the schema, or more than 1? If so, what results would you want? Give a concrete example, preferably suing commonly available tables (like those in the SCOTT schema) so that the poepl who want to help you can re-create the problem and test their ideas.

Please sugges the link helpful for writing efficient sql queries

Please suggest any good resource that is weblink which can help me in optimizing sql queries. especially while writing select statements improve the execution time of the sql query.
Thanx in advance
prasanth

in general I found books from O'Reilly very helpful (not only for Oracle, but for Unix too).
Moreover there is pretty good Oracle Documentation available.
After all, it's not only about writing good queries, but also about setting up data-models, indexes, primary keys, etc.
Look for a real slow computer, take a lot of data, then try writing your speedy queries. This is the school of hard knocks, on the long run it's the best training.

Need Help with Formula using SQL maybe

I need help! I work with Crystal reports XI and usually manage just fine with the Formula editor but his one I think will require some SQL and I am not good at that.
We are running SQL 2000 I think (Enterprise Manager 8.0) Our sales people schedule activities and enter notes for customer accounts. Each is stored in a separate table. I need to find activities that are scheduled 240 days into the future and show the most recent note that goes with the account for which that activity is scheduled.
The two tables, Activities and History, share the an accountID field in common that links them to the correct customer account.   I want to look at dates in the Startdate.Activities field more than 240 days in the future and show the most recent note from the History table where the accountid's match. I figure my query will contain a join on AccountID.Activities and AccountID.History used with Max(completedate.History) but I do not understand how to word it.
I would like to perform all this in crystal if possible. I humbly request your help.
Membery

You SQL would look something like this...
SELECT
a.AccountID,
a.BlahBlahBlah, -- Any other fields you want from the Activities table
h.LastComment
FROM Activities AS a
LEFT OUTER JOIN History AS h ON a.AccountID = h.AccountID
WHERE (a.ActivityDate BETWEEN GetDate() AND DateAdd(dd, 240, GetDate()))
AND h.HistoryID IN (
     SELECT MAX(HistoryID)
     FROM History
     GROUP BY AccountID)
This method assumes that the History table has a HistoryID that increments up automatically each time a new comment is added... So a comment made today would always have a higher HistoryID that one made yesterday.
If I'm wrong and there is no HistoryID or the HistoryID doesn't increment in a chronological fashion, it can still be done but the code is a bit more complex.
HTH,
Jason

Need help with min max sql

hi all, forgot i had a user name and password and haven't needed help for quite a bit since i didn't do sql for a while but now i'm back at reporting again...
Here is a sample table as i remember it:
Item     Date     Time     Time Frame     Duration     Duration Frame
A     20100926     0     5     500     10
A     20100926     600     10     500     30
A     20100926     1500     12     100     30
B     20100926     1800     28     200     40

B     20100926     2600     15     600     60
B     20100926     3600     30     200     70
Results Set (expected):
Item     Date     Time     Total Duration
A     20100926     0     1600:20     --basically max (time+duration) - min(time+duration)
B     20100926     1800     2000:00
Sorry, but. I didnt put my sql statement as I wasn't planning on posting and left it at work, but, i've been looking on internet and people say to use min/max function and i've attenpted it with it works with just this table (without grouping). But as soon as i group it the values seem to mess up.
Last i remembered it gave me:
Item     Date     Time     Total Duration
A     20100926     0     1600:30     --basically max(time+duration) - min(time+duration)
B     20100926     1800     2000:70
I think it's looking at max duration which is 30&70 and hence it retrurns those values in the result set. Is it because of the max function hence it's returning this value? any help is appreciated. thanks

Need help in writing a vbscript

Hi,
I need help in wring a vbscript. I have serached for the vbscript on the net, but could not find any.
I need to add a file to an msi using vbscript. - That's the requirement.
For this I have done the following with the help of vbscript.
1. With the insert statement I inserted a new copmonent in the FeatureComponent Table.
2. Now the next thing I did is, I inserted a new row in the File table using insert statement again. The file is uncompressed.
3. Since the file is a non-version file I also added a row in the MSIFileHash table.
4. Also, now added the Component in the component table.
After doing this I am able to see the chnages in the mst, however whrn I try to install it I get an error 2725 (Invalid database tables).
Can somebody please post a vbscript which can add a file to an msi?

Hi All,
Thanks for all your responses.
Yes, It is not so easy. I never said it was. Thanks for pointing out Orca. We use Orca on a daily basis.
What exactly I am looking at, is this.
We have some standard applications which needs to be repackaged every month. The repackaging process is same and does not change at least for these packages. So I was actually looking at automating these things.
What I did so far.
First we have created an object for Windows installer. I have then taken a copy of the original msi and then opened the database of this temporary msi database in transact mode. Once the database is opened we can use select, insert, update
and delete statements to update the database.
I could successfully add a registry to the msi. The component was also added successfully to the component table. I also could make changes to the Property table.
The tricky part comes with the addition of file to the file table.
The addition of file requires the following steps.
1. Add a new row to the file table. This can be done with the Insert statement.
2. We then need to associate the file to a new component or any other component already existing in the msi. In my case I am creating a new component.
3. We then have to associate this components to a feature in the FeatureComponents table.
4. Since the file I am adding is a non-versioned file, a new row also has to be added to the MSIFILEHASH table.
I could see the changes that I have done using the mst. But when I try to install the msi with the mst, I get the error 2725. I checked everything. All the other steps except for the file addition works fine.
To check whether I am indeed right, I have did this.
Skipped the file addition part to the msi. Every other change that I make works and I am able to install the msi with the mst successfully.
For obvious security reasons I will not be able to share the vbscript with you. If you guys think, that this is not a right forum for this question, please let me know the right forum. I have been stuck with this issue from the past 6 months. Any help would
really be appreciated.
