My obersvations for poor performance (although you have not defined what is "poor")
1. Why ORDER BY in cursor ?
2. Why CURSOR itself ?
It seems to me that all you are doing is checking whether the SQL (in cursor) returns any data. If yes, yo are updating ORDERS table. You should be able to eliminate cursor entirely. That will save all processing on cursor.
If you can explain (in english) what you are trying to achieve, I may be able to provide better solution.

SQL logic help for pl/sql block

Hi All,
I need your suggestions and comments for the below issue:
I have two tables: table A and table B
Table A has two columns as id and counts:
Id Counts
99 10
999 13
9999 7
Table B has two columns as Id and order:
Id Order
99 1
999 2
9999 3
We need to update Order in Table B such that Id having highest count in table A has Order as 1 in table B and it keep on increasing the order for other Ids based on decreasing counts in table A. This will be like a job which will run daily and look for counts in table A and update Order in table B according to it.
It seems to be simple but i am not getting it. Please help me out of this by writing some PL/SQL block.
I will really appreciate your all comments and responses.
Regards
Dev

Hi All,
I am really greatful to all fo you for all your replies and comments. I change ORDER table to ORDERS. All you replies worked for me but there is some slight change in scenario which i need to discuss with you all.
E.g: Table A has 10 rows like below:
Id Counts Type
99 10 A
999 13 A
9999 7 C
99 4 B
999 2 C
88 2 A
77 1 C
777 3 B
777 5 A
888 2 CIf you'd like help, please post CREATE TABLE and INSERT statements for your sample data (including table b as it is before the UPDATE or MERGE).
I populate data in Orders column Table B based on id, by grouping sum of counts for that id in table A.
Id 999 has highest sum(count) as 15, so it has orders as 1 in Table B and do same for descending counts for each Id.
Table B has 5 rows like below:
Id Orders
99 2
999 1
88 4
777 3
555 5
Assume Table B as static(no new record comes in it) but only its Orders changes for each Id based on counts for that Id in Table A. As you see, Table B has id 555 which is not in Table A, so we need to update its orders to the highest number by taking its Count as 0(zero). Sorry, it's unclear what you want to do.
Post what you'd like table b to look like after the UPDATE or MERGE.
Right now i am doing it like this:
declare
     cursor c1 is
     select Id, SUM (COUNT), RANK () OVER (ORDER BY SUM (COUNT)) rnk
     from TableA      AND Id IN (SELECT Id FROM TableB)
GROUP BY Id
ORDER BY rnk DESC;
i NUMBER := 1;
begin
for curr in c1
loop
     update TableB
set orders = i
     where id = curr.id;
     i := i + 1;
end loop;
end;I'm not sure what you're trying to do, but I'll bet you don't need PL/SQL to do it. Use a single UPDATE or MERGE statement (inside PL/SQL if necessary).
But it is not updating orders for Id 555 in TableB.There is no row for id=555 in table b, and, according to your requirements, there never will be, because "Table B as static(no new record comes in it)". It's behaving exactly as you said you wanted it to. What's the problem?
Please provide your suggesstions on what needs to be done to take care of this scenario. I will really appreciate your all suggesstions and comments. Please let me know if need some more explanation.Whenever you have a problem, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only), and the results you want from that data.
In the case of a DML operation (such as UPDATE) the sample data should show what the tables are like before the DML, and the results will be the contents of the changed table(s) after the DML.
Explain, using specific examples, how you get those results from that data.
Always say what version of Oracle you're using.

Need help for the sql statement !!!!!

hi all,
i need a sql statement for a query, how can i get the result from the rownum between 100 and 150?
plz help

use a scrollable statement:
PreparedStatement stat = Connection.prepareStement("select * from blah", ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_UPDATABLE);
ResultSet rs = stat.executeQuery();
rs.absolute(100);
while (rs.next()) {
String something = rs.get(1);
Look into the JDK API reference for ResultSet to get an expalantion of scrollable statements.

Help for Pl/SQL Logic & Syntax used

Hi, in Ivan Bayross' book, following example is given illustrating use of triggers.
Create trigger audit_trail
After update or delete on customer
for each row
DECLARE
oper VARCHAR(20);
BEGIN
If updating then
oper :='UPDATE';
End if;
If deleting then
oper :='DELETE';
End if;
Insert into audit_cust
Values(*:OLD.CUST_NO* , *:OLD.FNAME* );
END;
Questions :*
1. Why : symbol is used in insert query above? Viz. :OLD.CUST_NO
what does it indicate ?? ALso, what does . ( dot operator) indicates?
OLD is not table name.
2. In the program above what does this line mean??
If deleting then
oper :='DELETE';
End if;
We are just assigning value 'DELETE' to oper variable ?? or something else??

Hi,
So, still struggling on Ivan's book, eh ;-) ?
1. :OLD and :NEW means you can refer to the old and new column values.
They are only usable in triggers.
So, if you're updating column X from 1 to 2, the value of :OLD.X = 1 and :NEW.X = 2 in your trigger only.

http://www.oracle.com/pls/db102/search?word=TRIGGER&partno=
We are just assigning value 'DELETE' to oper variable ?? or something else??I guess the autor meant do do this:

for each row
DECLARE
oper VARCHAR(20);

If updating then
oper :='UPDATE';
End if;
If deleting then
oper :='DELETE';
End if;
Insert into audit_cust
Values( :OLD.CUST_NO, : OLD.FNAME, oper );
END;He probably forgot to insert the oper variable in his audit table,

Help asked for a sql request - thanks

Hello,
I'm not a sql Guru... Who can help for this sql request ?
First I have this:
SELECT ADDINFO_ID, INFO, LANGUAGE_FK, ENGLISH_NAME
FROM V_ADDINFOS
WHERE LANGUAGE_FK = 'EN' (which is very simple...-)
But now complicated... I have to add this in the same request:
select sum(val) as nbrInfo
from(
select count(*) val from eccgis where addinfo1_fk = ADDINFO_ID
union all
select count(*) val from eccgis where addinfo2_fk = ADDINFO_ID
union all
select count(*) val from eccgis where addinfo3_fk = ADDINFO_ID
union all
select count(*) val from thirdgis where addinfo1_fk = ADDINFO_ID
union all
select count(*) val from thirdgis where addinfo2_fk = ADDINFO_ID
In other words, for each row of the first select, I need to know how much it is linked in the tables eccgis and thirdgis...
Hope is is clear... -)
Thank you very very much,
Michel

Hi, Michel,
Almost anywhere that SQL allows an expression (such as a column name, literal or function call) it also allows a scalar sub-query, a SELECT statement based on any table (or tables) that returns one column and (at most) one row. Like other sub-queries, scalar sub-queries can be corellated to the main query.
To get the grand total you want on each row of your output:
SELECT ADDINFO_ID, INFO, LANGUAGE_FK, ENGLISH_NAME
, (select count(*) from eccgis where addinfo1_fk = ADDINFO_ID)
+ (select count(*) from eccgis where addinfo2_fk = ADDINFO_ID)
+ (select count(*) from eccgis where addinfo3_fk = ADDINFO_ID)
+ (select count(*) from thirdgis where addinfo1_fk = ADDINFO_ID)
+ (select count(*) from thirdgis where addinfo2_fk = ADDINFO_ID)
AS nrbInfo
FROM V_ADDINFOS
WHERE LANGUAGE_FK = 'EN';VERY IMPORTANT: Each sub-query must be in parentheses. You'll get a run-time error if any scalar sub-query returns more than one row. (Returning no rows is okay: the value will be NULL).
By the way, this looks like a bad table design. If each row in eccgis or thirdgis can be associated with more than one foreign key, they should be kept in a separate table. That's the standard way to handle many-to-many relationships.

Help for identifing top sql statements

Hi all,
We are doing load testing on oracle 9i with 500 concurent users. At some point of
time the database was hang. I would like to know which query is taking more time/
which resource occuping more. Can any body help in this regard.
Thanks in advance

Some useful information can be found in V$SQLAREA, for example :

2 from v$sqlarea
3* order by CPU_TIME desc;

Need help for sql statement

Hi,
Need help to write sql statement.
create table t_dt ( dt_start date, dt_end date, amount number);
insert into t_dt values('1-Jan-10','10-Feb-10',12);
insert into t_dt values('11-Feb-10','10-Mar-10',10);
insert into t_dt values('11-Mar-10','20-Apr-10',8);
insert into t_dt values('21-Apr-10','28-Jun-10',10);
insert into t_dt values('29-Jun-10','20-Sep-10',10);
insert into t_dt values('21-Sep-10','10-Oct-10',10);
insert into t_dt values('11-Oct-10','31-Dec-10',8);
insert into t_dt values('1-Jan-11','10-Feb-11',8);
insert into t_dt values('11-Feb-11','10-Mar-11',7);
insert into t_dt values('11-Mar-11','20-Apr-11',6);
insert into t_dt values('21-Apr-11','28-Jun-11',6);
insert into t_dt values('29-Jun-11','20-Sep-11',6);
insert into t_dt values('21-Sep-11','10-Oct-11',4);
insert into t_dt values('11-Oct-11','31-Dec-11',8);
Result should be like below..
dt_start     dt_end     Amount
1-Jan-10     10-Feb-10     12
11-Feb-10     10-Mar-10     10
11-Mar-10     20-Apr-10     8
21-Apr-10     10-Oct-10     10
11-Oct-10     10-Feb-11     8
11-Feb-11     10-Mar-11     7
11-Mar-11     20-Sep-11     6
21-Sep-11     10-Oct-11     4
11-Oct-11     31-Dec-11     8
Just to explain the example, take a row with start date as 21-Apr-10 in the above insert statements, since it has the same amount for next two rows (i.e. with start date '29-Jun-10' and '21-Sep-10') these 3 rows should be converted to represent only 1 row in the result and the start date and end date should be changed per the result shown above.
Thanks.

How will sql certification be helpful for a datamining career

Hi,
I have recently started to learn oracle and i am planning to go fro Sql certification in Oracle 9i. I also have a plan of venturing into datamining utilities in oracel 9i. Few advised that sql cert can be a good starting point. Can any one share some word of wisdom on my option or might suggest some other alternatives that might prove to be useful.
Thanks in advance

How can we know how many processors are enough to buy?
I know that each SQL Server edition and version has it's different limitation of the number of processors it can support, for example SQL Server 2012 Standard Edition can support up to 4 sockets or 16 cores per SQL Server Instance, but this does not mean

Need help trouble shooting Database Gateway for MS SQL Server setup, getting ORA-28546 error

Dear All,
I am trying to setup Oracle Database Gateway for MS SQL Server(I don't have admin access to the MS SQL Server). When I try to test the dblink connection, I get the following error.
I issued select * from dual@xyz;
ORA-28546: connection initialization failed, probable Net8 admin error
ORA-28511: lost RPC connection to heterogeneous remote agent using SID=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))(CONNECT_DATA=(SID=dg4msql)))
ORA-02063: preceding 2 lines from xyz
28546. 0000 - "connection initialization failed, probable Net8 admin error"
My setup is the following.
1. Oracle 11gR2 running on Oracle Linux 6, the same version gateway is installed on the same server, but different home directory.
2. Oracle DB home directory is /u01/app/oracle/product/11.2.0/dbhome_1, gateway home directory is /u01/gateway.
3. I use the same listener.ora file for both the db and the gateway.
4. the contents of my listener.ora, tnsnames.ora and the initdg4msql.ora are below.

Obviously, I would like to get this setup to work, but I also have couple other questions regarding this setup.
1. When installing the gateway, it asks to run the root.sh script. the root.sh script as for the following.
Enter the full pathname of the local bin directory: [/usr/local/bin]:
The file "dbhome" already exists in /usr/local/bin. Overwrite it? (y/n)
[n]: n
The file "oraenv" already exists in /usr/local/bin. Overwrite it? (y/n)
[n]: n
The file "coraenv" already exists in /usr/local/bin. Overwrite it? (y/n)
[n]: n
is the above answer correct?
Thanks for reading.

Loading XML parser for PL/SQL

I am working my way thru 'Building Oracle XML Applications' by Steve Muench.
I am getting a problem when I try to install the XML parser for PL/SQL
The following errors occur when I try to do

About 20 classes get loaded correctly. All the rest get ORA-29545 or ORA-04043 errors.
I expect the ORA-04043 errors are a result of the earlier errors.
The documentation seems to indicate that there is no need to do
dbms_java.grant_permission to load into your own schema.
I have NT4 (sp6)
Oracle 8.1.7
xmlparserv2.jar dated 24/8/2001 17:01 size 1,177,259
xmlparserv2_2027.jar gives the same errors.
Any help would be appreciated.

Was it definitely xmlparsev2.jar that you had to load?
I recently started going through some of these examples as well and found that the standard xml parser was there but that I needed to load the xml parser for PL/SQL. I did this using loadjava from a subdirectory within the xdk directory and everything worked fine.

Need help for understanding the behaviour of these 2 queries....

Hi,
I need your help for understanding the behaviour of following two queries.
The requirement is to repeat the values of the column in a table random no of times.
Eg. A table xyz is like -
create table xyz as
select 'A' || rownum my_col
from all_objects
where rownum < 6;
my_col
A1
A2
A3
A4
A5
I want to repeat each of these values (A1, A2,...A5) multiple times - randomly decide. I have written the following query..
with x as (select my_col, trunc(dbms_random.value(1,6)) repeat from xyz),
y as (select level lvl from dual connect by level < 6)
select my_col, lvl
from x, y
where lvl <= repeat
order by my_col, lvl
It gives output like
my_col lvl
A1     1
A1     3
A1     5
A2     1
A2     3
A2     5
A3     1
A3     3
A3     5
A4     1
A4     3
A4     5
A5     1
A5     3
A5     5
Here in the output, I am not getting rows like
A1     2
A1     4
A2     2
A2     4
Also, it has generated the same set of records for all the values (A1, A2,...,A5).
Now, if I store the randomly-decided value in the table like ---
create table xyz as
select 'A' || rownum my_col, trunc(dbms_random.value(1,6)) repeat
from all_objects
where rownum < 6;
my_col repeat
A1     4
A2     1
A3     5
A4     2
A5     2
And then run the query,
with x as (select my_col, repeat from xyz),
y as (select level lvl from dual connect by level < 6)
select my_col, lvl
from x, y
where lvl <= repeat
order by my_col, lvl
I will get the output, exactly what I want ---
my_col ....lvl
A1     1
A1     2
A1     3
A1     4
A2     1
A3     1
A3     2
A3     3
A3     4
A3     5
A4     1
A4     2
A5     1
A5     2
Why the first approach do not generate such output?
How can I get such a result without storing the repeat values?

If I've understood your requirement, the below will achieve it:
SQL> create table test(test varchar2(10));
Table created.
SQL> insert into test values('&test');
Enter value for test: bob
old   1: insert into test values('&test')
new   1: insert into test values('bob')
1 row created.
SQL> insert into test values('&test');
Enter value for test: terry
old   1: insert into test values('&test')
new   1: insert into test values('terry')
1 row created.
SQL> insert into test values('&test');
Enter value for test: steve
old   1: insert into test values('&test')
new   1: insert into test values('steve')
1 row created.
SQL> insert into test values('&test');
Enter value for test: roger
old   1: insert into test values('&test')
new   1: insert into test values('roger')
1 row created.
SQL> commit;
Commit complete.
SQL> select lpad(test,(ceil(dbms_random.value*10))*length(test),test) from test;
LPAD(TEST,(CEIL(DBMS_RANDOM.VALUE*10))*LENGTH(TEST),TEST)

Help me in resolving this.

Hi,
I believe NVARCHAR is an unsupported type...
The following document lists the supported data types for SQL Server stored procedures and functions... NVARCHAR is not in the list... :-(
http://docs.oracle.com/cd/E23943_01/integration.1111/e10231/adptr_db.htm#CHDEBEEE
Hope this helps...
