SQL & PL/SQL :: Running Queries Of 2 Different SID On 1 Pane
Jun 4, 2013
I have two queries that I need to run and compare the outputs against each other. Each query runs on a different host. I can run each query on a different pane (Window - I am using Toad for running query). What I am trying to do is:
- Run both queries on a single pane
- Compare the output where if a "study" matches on both query output, then display the result.
To being with, is it possible to run the queries on a single pane by defining SID string as a part of query syntax......?
SELECT study,
TO_CHAR (completed_date, 'mm/dd/yyyy') completed_date, status
FROM ...
I am using Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - Production
I have 2 schemas in my application.
1. Application schema 2. EOD(End of day) schema.
End of day schema is populated from Application schema whenever user runs EOD process. The tables are pulled like this.
1. Master tables : Always deleted and reinserted at each EOD process 2. Log tables for each transaction table: Delta between the last EOD and current EOD data is pulled and are used for populating transaction tables 3. Transaction tables: These are populated from log tables pulled from previous step. The logic is like this
Now based on these tables about 30 reports are generated in EOD schema. Please note that each transaction table will have a EOD_ID and any report generated uses the where condition <transaction table>.EOD_ID = <current EOD_ID>
My log table contract_log and transaction table is contract in EOD schema.
(Since the change of rate 11 is visible on 2nd Jan 2010)
This logic is working fine. But we run more than 20-30 EODs the processing time increased to 10-15 hours.
It took some time to figure out the issue as a single query when run from toad or pl sql developer runs in few seconds but as a part of the whole package it takes 2-3 hours(each query).
The problem found was that oracle execution plan gets corrupted when the process starts. So what we did was to analyze the tables after they are pulled. This perfectly solved our problem. Currently the whole process is taking only about 12-13 minutes where about 3 minutes is lost on analyze tables and indexes. I know this is a temporary solution as I need to get out of online analyze of tables and indexes.
My code for table and index regeneration is as below
PROCEDURE sp_gather_table_index_stats(pc_table_name VARCHAR2) IS CURSOR cur_ind IS SELECT index_name FROM user_indexes WHERE table_name = pc_table_name; BEGIN EXECUTE IMMEDIATE ' begin DBMS_STATS.gather_table_stats(user,' || '''' || pc_table_name || '''' || '); end;'; FOR cur_ind_rows IN cur_ind LOOP EXECUTE IMMEDIATE ' begin DBMS_STATS.gather_index_stats(user,' || '''' || cur_ind_rows.index_name || '''' || '); end;'; END LOOP; END;
An user is running some queries and that's making database hang. I want to view what queries this user is running. Can this be done by session auditing turning on?
I am using 10.2.0.4 oracle database on Solaris 10. We are running some Peoplesoft upgrade on one of the database from last 6-7 hours. The status of the session is INACTIVE from couple of hours. And the sql_id is null for these sessions.
select sid,serial#,STATUS,to_char(logon_time,'DD-MON_YY HH24:MI:SS') from v$session where username like '%&usern%' ORDER BY 4 DESC; 533 2234 INACTIVE 04-MAR_10 01:59:02 525 5919 ACTIVE 04-MAR_10 01:54:50 534 4186 INACTIVE 04-MAR_10 01:05:15 520 2320 INACTIVE 04-MAR_10 00:29:44
[code].....
While when i see the current sql from the v$active_session_history, it keep on changing after every 10-15 minutes. Using below query to find the sql_text for the session from v$active_session_history.
select sql_id, sql_text from v$sql where sql_id in ( select sql_id from v$active_session_history where session_id=511
[code].....
We have not faced issue like this during Peoplesoft upgrade. what could be the reason that the status is not changing while the base sqls keep on changing after every 10 minutes.
There is a requirement in my database that I want to restrict the user from directly running queries on database from third party tools such as pl/sql developer and toad.
There is a utility in SQL product_user_profile through which this can be done but it is only restricted if you run the query through sql plus. If I want to restrict and (give suppose select,insert) to a user for directly running queries through PL/SQL.
our system has always been running on mysql database and recently we have switched to oracle. As the current system is coded using mysql query syntax, when i run this program using oracle database, i got a error. The language that I'm using is JSP.
this is the error message:
The following query could not run on oracle. To convert these mysql queries to oracle compatible queries.
SELECT productID,productName FROM products order by productName;
select newsID,newsDate,newsHeadLine1 from news order by newsDate Desc limit 3
SELECT fuji_products.productID, productName_Display FROM products,products_availability where products_availability.productID=products.productID and (product_status='enabled' or product_status='all') AND category='12'
SELECT catID, catSub1 from category where catSub = '"+ prodCat +"' AND catSub1 is not null group by catSub1 order by catSub1
- returning from the procedure 2 ref cursors containing result set of 2 queries - returning from the procedure 1 ref cursor containing result set of that 2 queries as one (with UNION ALL)?
which contains multiple contact details for users of different types; type 1 is home, type 2 work etc. The following query returns the user's number and the latest home number for that user.
select user, details as latest_home_number from nc_test t where type = 1 and updated = (select max(updated) from nc_test t2 where t2.user = t.user and t2.type = t.type) order by t.user
However I am not very experienced with sql and I am not sure how to create a view which would contain the fields:
I have to change some queries from SQL to Oracle but I couldn't convert these queries because they use some system tables in SQL that I don't know the equivalent Oracle tables. Following are SQL Queries
1. SELECT name, xtype FROM sysobjects WHERE xtype IN('U', 'V') AND name <> 'dtProperties' AND objectproperty(id, 'IsMSShipped') = 0 ORDER BY name
2. SELECT tS.name FROM sysobjects AS tS WHERE (tS.name IN (SELECT name FROM sysobjects WHERE xtype = 'U') AND xtype ='U') OR (tS.name IN (SELECT name FROM sysobjects WHERE xtype = 'V') AND xtype ='V')
3. SELECT o.name as TableName, c.name as FieldName, c.colid as Field_Ordinal, t.name as FieldType, c.length as FieldLength, c.prec as FieldPrecision, c.scale as FieldScale, c.isnullable, c.iscomputed, CASE WHEN c.status & 0x80 > 0 THEN 1 ELSE 0 END AS isidentity, columnproperty(o.id, c.name, 'IsRowGuidCol') as isrowguidcol FROM (sysobjects o JOIN syscolumns c ON o.id = c.id) JOIN systypes t On c.xtype = t.xtype WHERE o.xtype IN ('U', 'V') AND (t.xtype = t.xusertype)
On a tab page should be displayed the result of four indifferent queries, each based on a stored procedure.At the moment, the queries are processed serially, by the statements:
We have the following case: an application modifies a table in an Oracle db (10.2.0.3.0).
Unfortunately the update SQL statements from the application always use the condition "where Column1 = 'some given value'" which is wrong (never mind why).
It should be instead "where Column1 = 'some value' and Column2 = 'val for Column2'. The 'val for Column2 will be taken from the very SQL query being issued (we can make the application do an update for Column2 even if the value in it never changes).
So all the update queries from the application look at the moment like that:
"update my_table set Column2 = 'val for Column2', Column3 = 'some other values', Column4 = 'some other value' where Column1 = 'some given value'".
We would like to capture them and somehow on the fly modify them to look like that:
"update my_table set Column2 = 'val for Column2', Column3 = 'some other values', Column4 = 'some other value' where Column1 = 'some given value' and Column2 = 'val for Column2'".
Can a trigger "before update" do it? For some reason we cannot at the moment ask the vendor to change the hard code of the application so we are looking for a temporary workaround.
I have some troubles when I try to retrieve last executed queries in a database.
For example;
I run the script below:
select distinct t.first_load_time, t.sql_text, t.last_load_time, s.username from v_$sql t, v$session s where s.username='SYS'
And as a result, I retrieve the queries executed by SYS user. But the problem is that, if SYS user executed the same query more than once, only the very first record is shown.
It is like this,
SYS user executes "select * from table_abc" at 10:54:35, and after that SYS executes the same query at 13:45:55. and after running the query above, I can only see the record which was executed at 10:54:35. I need to see the both results.
How I can get the union result of 2 queries and put them in xml result, but I want each query to be in seperate xml element. I don t want to put 1 single xmlelement and do a From then construct a virtual table uniting the 2 subqueries
I mean I don t want something like the following:
(Select XMLAGG( XMLELEMENT("credit",

Except the 2nd alternative is not working I get error message: "SQL command not properly ended"
I am trying to validate a monthly report so was trying to write queries to get different criteria into one table. So my first query returns all the product,second query returns all the enrolled customers, 3rd query returns all the cancelled customers and 4th query returns all the newly enrolled for a month. Is there a way I can pass the first query results into 1st column, 2 query results into 2nd column, 3 query results into 3rd column and so on.
I tired writing the SQL several different ways and have spent a day on it and still cannot figure it out. I am using SQL Developer.
I am trying to trace the SQL statements executed against a particular database user. I don't have AUDITING enabled and I am using Oracle 11g.I have the following query :
SELECT S.MODULE, SQL_TEXT , S.EXECUTIONS FROM [code].....
But if multiple users running the 'APP.EXE' are connected to the same db user, I am not able to understand which OS user executed which query. So I tried to join with V$SESSION view to get the user details.
SELECT S.MODULE,SQL_TEXT ,SN.OSUSER, SN.MACHINE, S.EXECUTIONS FROM SYS.V_$SQL S, SYS.ALL_USERS U, V$SESSION SN WHERE S.PARSING_USER_ID=U.USER_ID AND UPPER(U.USERNAME) IN ('USERNAME') AND (UPPER(S.MODULE)='APP.EXE') AND S.SQL_ID=SN.SQL_ID ORDER BY S.LAST_LOAD_TIME
But this doesn't seems to be working(In my case it didn't return any rows) I have also tried the following
select S.SQL_TEXT,S.MODULE,S.EXECUTIONS,SN.OSUSER,SN.MACHINE,SN.SID, U.username,U.user_id from SYS.V_$SQL S, v$open_cursor oc,SYS.ALL_USERS U,V$SESSION SN where S.PARSING_USER_ID=U.USER_ID AND UPPER(U.USERNAME) IN ('USERNAME') AND (UPPER(S.MODULE)='APP.EXE') and oc.SQL_ID=s.SQL_ID AND SN.SID=OC.SID AND SN.SADDR=OC.SADDR;
but I am not sure whether this is giving the right results. So, I have the following questions
1) How do I get the queries executed by each session?
2) The EXECUTIONS column of V_$SQL seems to the executions from all the sessions. How do I know the number of times a particular query is executed by a session?
3) How long a record about a query will be stored in V_$SQL? When do Oracle delete it from the view?
I'd like to audit a table for any SELECT queries that are executed against it with no WHERE clause. I've read the documentation on DBMS_FGA carefully, and as close as I can tell, creating a policy with a NULL audit_condition causes all queries against the table to be audited, which isn't what I'm looking for.
I wonder how I can limit the queries in a table? This limitation would be that from a certain time, it allows queries. Before the opening hours, permitting no select.
Example: Allow SELECTs in table only after 16 p.m.
I am trying to display the results from 2 queries, one is supposed to display the count of the employees, per department, who win over the average of the entire company and the other one is supposed to display the count of the employees, per department, who win under the average of the entire company.
I used a UNION ALL, but all it does is merge the results from the ones that win over and under the average into one row, is there a way to separate them? I tried assigning names to each salary using AS but it only displays the first I put in.

I am having 7 tables consider A,B,C,D,E,F,G. whereas A is master table and others are dependent on table A. columnA is referential key for all tables. Table A is having one DateRange column.I have successfully created range partitioning with partitioning key is DateRange. and Refeernce partitioning on other tables with column referring to ColumnA with foreign key. Also created local indexes on partitioned key DateRange.
Problem is that, while fetching complex queries for reports, it is taking more time as compared to non partitioning structure. Is ref partitioning affecting on complex queries, queries returning more rows?
I have a few questions about querying using ranges and comma separated lists. The basic situation is a request comes in with part numbers that can be formatted in a range, comma separated lists or both. For an example, the request contains the following part numbers:
<pnum> 1-10, 14, 17, 11, 21-24 </pnum>
I can muster a basic SQL statement to query for this by hand (more then one way to do this)-
SELECT * FROM part_table WHERE pnum BETWEEN '1' AND '10' OR pnum BETWEEN '21' AND '24' OR pnum IN (14, 17, 11);
is there a way to create the BETWEEN statement so that the dash doesnt need to be parsed out of the request? (like BETWEEN '1-10') or something that functions to that extent? Is it also possible to nest the BETWEEN statements (or the functionality of the BETWEEN) in the IN statement?
create table test_a (id number, b varchar2 (20)); create table test_b (id number, a number, b number, c number, d number, e number, f number); insert into test_a values (1,'Manu'); insert into test_a values (2,'Tanu'); insert into test_a values (3,'Anu');

convert the query above using joins instead of scalar queries, as scalar queries decreasing the performance.
