Query :
SELECT B.*,U.ID, SD, LE, LAE
FROM client.Temp B, client.Master

Cluster bar chart- sql query please help-
Hi,
I am trying to create cluster bar chart and am stumped with this sql query.Any help is appreciated.
Here is my table
city region issue value
c1 north i1 y
c1 north i2 y
c2 north i1 n
c2 north i2 y
c3 south i1 y
c3 south i2 n
c4 east i1 n
c4 east i2 n
The bar chart will have 3 series, north south and east.
And labels will be i1 and i2. value will be number of times this issue was encountered(y) in this region.
How can I get something like this from the above table-
region issue count(yes)
north i1 1
north i2 2
south i1 1
south i2 0
east i1 0
east i2 0

Thanks in advance.
Neethu MohanHi Neethu,
It gives you an overwiew of blocking Oracle sessions.
1. In general, the SQL checks Oracle sessions (SID's) that were requirering a DML lock ('TM') and now holding row locks (TX) to prevent destructive interference of simultaneous conflicting DML or DDL operations. DML statements automatically acquire both table-level locks and row-level locks ('TX') => holders
It joins these with the sessions that are waiting of releasing the lock by the holders => waiters.
2. it retrieves the detail information wich Oracle process , the object (table) , it's row , block and file
are affected by the locks.
3. Normally, the locks are only hold for a short period of time. If you have blocking sessions it may be of a log running task (i.e. mass data update of a table) ; but it could also be a application bug due to improper handling of concurrent updates of the same object.
4. Tuning
V$tables are expensive to query: Why?
v$ tables are generally Oracle memory structures.
v$ tables are not read consistent.
v$ tables require latches to access -- cannot modify and read memory at the same
time.
heavy access to v$ tables like this may cause some serious heavy duty contention.
Especially if you self join V$lock several times.
So the best would be to save the contents of V$LOCK in some table:
Create table mylocks as select * from v$lock;
Use that table for self-joining and joins to the other tables.
You can also CTAS the other v$ tables to bypass the performance bottleneck while retrieving
v$ directly.
You can empty or drop the created tables any time for new data.
Because you want to investigate only lock hold for a longert time to copy the v$ memory structures into
physical tables is not a disadvantage. You certainly will wait longer on finishing your query
instead of copy them into the tables.
Hope this helped

Passing parameter to a SQL query - Please help
Hi All,
I am new to JDBC. I have been trying to pass an external variable to an SQL Query.
The query is
String username1="le";
PreparedStatement pstmt = null;
pstmt = c.prepareStatement("select * from users where USER_NAME like '%?%'");
pstmt.setString(1, username1);
pstmt.executeQuery();
ResultSet rs = pstmt.getResultSet();
I am trying to retrieve values from the users table where the USER_NAME column value that is a String contains the supplied value username1.
I am using the question mark (?) character to pass the value from the variable username1. I am also using the '%' substitution character which matches for any number of characters. So, the above query should retrieve rows where the USER_NAME is something like "charles","leander","Elena" etc.( that contains "le")
I am getting the error:
SQLException: java.sql.SQLException: ORA-01006: bind variable does not exist
I changed the query to
PreparedStatement pstmt = null;
pstmt = c.prepareStatement("select * from users where USER_NAME like '% " + username1 + "%'");
//pstmt.setString(1, username1);
pstmt.executeQuery();
This time , it is not giving the error and retrieving properly.
But I want to use the original query and use the "pstmt.setString(1, username1); " . Is there any way of achieving this?
Please help.
Cheers,
charles_amhi,
try this...
String username1="%le%";
pstmt = c.prepareStatement("select * from users where USER_NAME like ?")
pstmt.setString(1,username1);
cheers,

Hi,
I have a question about the performace of this SQL query. I have to display only 8 rows from this query. How is this query will be executed? What happens if the inside query returns more than 500 rows? Will it slow down?
SELECT * FROM (SELECT prod_date, create_date, prod_name, priority, status FROM CUST_PROD
WHERE cust_id = 100 and Status in(1, 5) order by priority, prod_name ) WHERE ROWNUM < = 8
Thank you..Its hard to tell what effect more data will have on a query until it happens. As BluShadow pointed out you're not talking about huge amounts of data; with luck the numbers you mentioned will not make any difference.
It looks like you're using the inline view to a top N query. You could look into using the RANK() function to do something similar. -

I can`t give you TKPROF, because I got no access to that trace files!
Any thoughts would be appreciated:-)
Edited by: PhoenixBai on Sep 27, 2009 3:13 PMPl post the output of the following
select count(*) from wf_stat_hist;
select count (distinct wrk_itm_id) from wf_stat_hist;
select count (distinct upd_login) from wf_stat_hist;Your code is performing poorly because your WHERE clause is searching on a column on WF_STAT_HIST that is not indexed. Hopefully the output of the above code will determine which column (WRK_ITM_ID or UPD_LOGIN) is a better candidate to be indexed on. If neither of these columns is a good candidate, you may have to change the WHERE clause to be more selective rather than do a full table scan as the plan indicates.

I need to denormalize data in sql query, please help!

I get, eg:

Thanks in Advance for your help.
I'm using Oracle 11g, SQL Dev 3.0select case when x = 1 and y = 0 then 3

How to add pl sql query into help text of an item.
Hi
In my database i have added comments to the colums. I would like to use this comments in the help text of the items of my application. I have the query but when I use it in the help text attribute it does not execute the query, it presents the query.
Any ideas?It is probably too late now, but note that if you create your application using the Create Application Wizard and Application Models, based on User Interface Defaults created in the SQL Workshop, any column comments will automatically become application help text.

Hi,
I have a query which is used in one of ur reports which tries to access 11 tables using oracle reports application. when users are trying to access thsi report its taking aroung 4 min. to compete the report, in a day we need this report to run on more than for nearly 70 times(70 reports in a day).
we provide the registration number, based on this number it generates the details of the owner, address, registration details, permits etc
we have more than 1gb of sga in which shared pool has nearly 750mb.

What's wrong with this sql query? Help
hi
i am having difficulty executing this query
ResultSet s=st.executeQuery("select * from employee where iden = ?"+id);
here in my program st is statement obg
iden is attribute name in table
id i am getting at run time from user
please help...it says wrong number of parameters
thank youThat's correct, get rid of the Question mark. Questions marks are used in PreparedStatements, but they are also used in pattern matching. I am assuming the iden is the table identity. Therefore, I am assuming it is numeric. If so, you can't use the question mark because pattern matching is only done with strings. If you are treating your statement as a PreparedStatement, then you have done it wrong. (See the API) Here is a code snippet from the API:PreparedStatement pstmt =
con.prepareStatement("UPDATE EMPLOYEES SET SALARY = ? WHERE ID = ?");
pstmt.setBigDecimal(1, 153833.00)
pstmt.setInt(2, 110592)It seems you are using a Statement object, so, you need to get rid of that question mark.

If I understood correctly your logic, and if the columns involved are of type varchar2, you can use the like operator:
and a.invoice_num like l.invoice_num || '%'
and c.invoice_num like mgr_apprv_lst.user_key || '%'
and c.invoice_num like pbl_apprv_lst.user_key || '%'In this case, Oracle will be able to use the indexes. If they are numeric, you need to do something like:
and a.invoice_num between l.invoice_num * 1000000
and l.invoice_num * 1000000 + 999999I hope this makes sense...
