Oracle sql query works

Can any body tell , how the sql select statement will works ? how it will come across the 3 phases 1.pharse 2.execute and 3. fetch
what is the parameter in oracle 9i and 10g for compress the dumpfile in export and import?

Hi,
Welcome to forums.. !!
Can any body tell , how the sql select statement will works ? how it will come across the 3 phases 1.pharse 2.execute and 3. fetch Try to refer to : How the select Query Works
Oracle documentation explains every thing, just spend some time.
what is the parameter in oracle 9i and 10g for compress the dumpfile in export and import?You must check the Oracle documentation. From high level the compress parameter works different for both versions while allocations the extents.

Oracle Sql Query issue Running on Different DB Version

Hello All,
I have come into situation where we are pruning sql queries on different DB version of Oracle and have performance issue. Let me tell you in brief and i really appreciate for your prompt response as its very imperative stuff.
I have a query which is running on a DB of version 7.3.4 and it takes around 30 mins where as the same query when run on 8i it takes 15sec., its a huge difference. I have run the statistics to analyze on 7.3 and its comparatively very high. Question here is, the sql query trys to select data from same schema table and 2 tables from another DB using DB link and 2 other tables from another DB using DB link.So,how can we optimize this stuff and achieve this run as same time as 8i DB in 7.3. Hope i am clear about my question, Eagerly waiting for your replies.
Thanks in Advance.

Difficult to be sure without any more detailed information, but I suspect that O7 is in effect copying the remote tables to local temp space, then joining; 8i is factoring out a better query to send to the remote DBs, which does as much work as possible on the remote DB before shipping remaining rows back to local.
You should be able to use EXPLAIN PLAN to identify what SQL is being shipped to the remote DB, If you can't (and it's been quite a while since I tried DB links or O7) then get the remote DBs to yourself, and set SQL_TRACE on for the remote instances. Execute the query and then examine the remote trace files, And don't forget to turn off the tracing when you're done.
Of course it could just be that the CBO got better,,,
HTH - if not, post your query and plans for the local db, and the remote queries.

Oracle SQL Query from EXCEL 2007 with prompt

Hello,
I have many excel reports where I am pulling information from our Oracle 9 db through Excel using the following method:
http://blog.mclaughlinsoftware.com/microsoft-excel/how-to-query-oracle-from-excel-2007/
http://blog.mclaughlinsoftware.com/2009/11/30/sql-query-in-excel-2007/
However, I am having trouble when I try the following query due to the prompt:
SELECT
IM.ITEM_GROUP,
IM.ITEM,
IM.DESCRIPTION
FROM
LAWSON.ITEMMAST IM
WHERE
IM.ITEM = '&ITEM';
Does any one know how I can connect a prompt to an excel cell and then pass the query on to Oracle, or have a PL SQL prompt work from Excel?
Thanks,
Ben

The 'prompt' as you call it is a sqlplus feature, so does not belong to the SQL language
You would need to write a stored procedure returning a resultset.
create or replace procedure foo(rc in out sys_refcursor, p_item) as
begin
open rc for
'SELECT
IM.ITEM_GROUP,
IM.ITEM,
IM.DESCRIPTION
FROM
LAWSON.ITEMMAST IM
WHERE
IM.ITEM = '||p_item;
end;
and call that using ODBC or asp.net
Obviously this is profusely documented.

Reg how an sql query works?

I am new to Oracle and sql/plsql. What is the background processes happening when an sql query is fired to the database?
In short how an sql query is actually working?
what are the steps involved in it?
pls provide me the links if it is tedious to reply
Thanks

Every SQL-Select Statement meets three stages parse, execute, and fetch. To know completely how SQL and PL/SQL work with Oracle, you must have to read the below Oracle Link seriously.

How does a SQL query work

Hi all...
How does a SQL query basically work? Is there any pseudocode for it?
How ro calculate the cost of query?
Can we find out what would be the execution time for a query before it is executed?
Thanks in advance.
Ameya

Hi Avinash,
Look closely mate!!!
You have done set autotrace on... meaning you are executing the statement while i am doing set autotrace traceonly explain meaning the statement would never get executed actually.. oracle optimizer will just select the desired plan and will show the output..
You can even ESTIMATE how many rows the qeury will return before even executing the statement using the same above tech.. i will show you how:
The explain plan gives this -- as long as you are using the CBO (cost based
optimizer). Doesn't matter if you have 1 or 50 tables. The last part of the
plan is the estimate output.
consider:
SQL> set autotrace traceonly explain
SQL> select e1.*, e2.* from emp e1, emp e2;
Execution Plan
0 SELECT STATEMENT Optimizer=CHOOSE (Cost=15 Card=196 Bytes=12544)
1 0 MERGE JOIN (CARTESIAN) (Cost=15 Card=196 Bytes=12544)
2 1 TABLE ACCESS (FULL) OF 'EMP' (Cost=1 Card=14 Bytes=448)
3 1 SORT (JOIN) (Cost=14 Card=14 Bytes=448)
4 3 TABLE ACCESS (FULL) OF 'EMP' (Cost=1 Card=14 Bytes=448)
196 = 14 * 14 -- thats right....
SQL> select emp.ename, mgr.ename from
2 emp, emp mgr
3 where emp.mgr = mgr.empno;
Execution Plan
0 SELECT STATEMENT Optimizer=CHOOSE (Cost=5 Card=13 Bytes=208)
1 0 MERGE JOIN (Cost=5 Card=13 Bytes=208)
2 1 SORT (JOIN) (Cost=3 Card=14 Bytes=112)
3 2 TABLE ACCESS (FULL) OF 'EMP' (Cost=1 Card=14 Bytes=112)
4 1 SORT (JOIN) (Cost=3 Card=14 Bytes=112)
5 4 TABLE ACCESS (FULL) OF 'EMP' (Cost=1 Card=14 Bytes=112)
Here is estimated that about 13 rows would be returned...
SQL> select count(*) from emp;
Execution Plan
0 SELECT STATEMENT Optimizer=CHOOSE (Cost=1 Card=1)
1 0 SORT (AGGREGATE)
2 1 INDEX (FULL SCAN) OF 'EMP_PK' (UNIQUE) (Cost=1 Card=14)
one row...
SQL> select ename, dname
2 from emp, dept where emp.deptno = dept.deptno;
Execution Plan
0 SELECT STATEMENT Optimizer=CHOOSE (Cost=5 Card=14 Bytes=252)
1 0 NESTED LOOPS (Cost=5 Card=14 Bytes=252)
2 1 TABLE ACCESS (FULL) OF 'DEPT' (Cost=1 Card=4 Bytes=44)
3 1 TABLE ACCESS (FULL) OF 'EMP' (Cost=1 Card=14 Bytes=98)
14 rows...
1 select ename, dname
2* from emp, dept where emp.deptno = dept.deptno and emp.ename like '%A%'
SQL> /
Execution Plan
0 SELECT STATEMENT Optimizer=CHOOSE (Cost=2 Card=1 Bytes=18)
1 0 NESTED LOOPS (Cost=2 Card=1 Bytes=18)
2 1 TABLE ACCESS (FULL) OF 'EMP' (Cost=1 Card=1 Bytes=7)
3 1 TABLE ACCESS (BY INDEX ROWID) OF 'DEPT' (Cost=1 Card=4 Bytes=44)
4 3 INDEX (RANGE SCAN) OF 'DEPT_IDX' (NON-UNIQUE)
1 rows.....
and this was all done without executing the query. See EXPLAIN plan and the
PLAN_TABLE.

SQL query works in access 2000 but not through JDBC

Hello to all as my first posted message, I have a bit of a pickle on my hands. I have a query which is critical to for my application to function.
In Access 2000
SELECT sb.SeatName
FROM SeatBooking sb, Movie m, MovieSession ms, Booking b
WHERE m.MovieId = ms.MovieId
AND ms.MovieSessionId = b.MovieSessionId
AND b.BookingId = sb.BookingId
AND ms.DateOfSession = #2003/04/16 07:15:00 PM#;
This query works fine. When I insert it into my code
String query = "SELECT sb.SeatName \n" +
"FROM SeatBooking sb, Movie m, MovieSession ms, Booking b \n" +
"WHERE m.MovieId = ms.MovieId \n" +
"AND ms.MovieSessionId = b.MovieSessionId \n" +
"AND b.BookingId = sb.BookingId \n" +
"AND ms.DateOfSession = #" +
cp.getMovieSessionAt(i).getTrueTimeOfSession() + "#;";
The last line of code returns #2003/04/16 07:15:00 PM#; Which is the exact same as in Access.
To rule out some possibilities
- there are other less complicated queries which access the same database but work fine. so my code seems to be ok
- I have tried to use Format() on ms.DateOfSession to match the return value of the java statement (Which is a general date in Access in the format of 16/04/2003 7:15:00 PM)
Any suggestions would be appreciated!

Hi Simon,

Clarification on using function in where clause of oracle sql query

I have an issue in regarding function using where clause of sql query..
We are facing performance issue while executing query, so in what ways to improve the performance of the query which i have posted below.
select col ,case when my_function(parameter)
from tab1 a ,tab2 b,tabl3 c
where a.column1=b.column2
and b.column3 =c.column6
and my_function(parameter)>0
Regards
Dinesh
Edited by: wild fire on May 18, 2012 4:15 PM

Dinesh,
remind that when you use a function in the where clause it normally will get started for each record in the table.
So your answer is two-fold:
1. make the function only start when needed by adding a function based index on the table (this will make inserts and updates slower)
2. make the function faster by adding the DETERMINISTIC clause if possible. this will make Oracle "cache" the result of the function.

Richard

Oracle SQL query for getting specific special characters from a table

Hi all,
This is my table
Table Name- Table1
S.no    Name
1          aaaaaaaa
2          a1234sgjghb
3          a@3$%jkhkjn

7          sdsaf$([]:'
8          <-fdsjgbdfsg
9           dfgfdgfd"uodf
10         aaaa bbbbz#$
11         cccc dddd-/mnm
The output has to be
S.no    Name
3          a@3$%jkhkjn
5          bbvxzckvbzxcv&^%#
7          sdsaf$([]:'
8          <-fdsjgbdfsg
10         aaaa bbbbz#$
It has to return "Name" column which is having special characters,whereas some special chars like -, / ," and space are acceptable.
The Oracle query has to print columns having special characters excluding -,/," and space
Can anyone help me to get a SQL query for the above.
Thanks in advance.

SQL query works in the SQLPlus, but fires parse error after being cut and pasted into

One of our client has a SQL query like this:
SQL> SELECT LNAME,
2 QUOTA/12,
3 (SELECT SUM(CAMT) FROM CONSULTING WHERE CONSULTANT = P.EMPLOYEE
4 AND ACTIVITYCODE = 'C'AND
5 CDATE BETWEEN '01-JAN-2001' AND '31-JAN-2001') AS SUM,
6 (SELECT SUM(CAMT) FROM CONSULTING WHERE CONSULTANT = P.EMPLOYEE
7 AND ACTIVITYCODE = 'C'AND
8 CDATE BETWEEN '01-JAN-2001' AND '31-JAN-2001') -
QUOTA/12 AS PL
9 FROM PERSONNEL P
10 ORDER BY LNAME;
Running the above query in the SQLPlus returns appropriate resultsets to the
user. After the same SQL being cut and pasted into a portal report
component, running the report component fires the following error:
Failed to parse query
Error:ORA-00911: invalid character (WWV-11230)
Failed to parse as XXX - SELECT LNAME, QUOTA/12, (SELECT SUM(CAMT) FROM
CONSULTING WHERE CONSULTANT = P.EMPLOYEE AND ACTIVITYCODE = 'C'AND CDATE

BETWEEN '01-JAN-2001' AND '31-JAN-2001') - QUOTA/12 AS PL FROM PERSONNEL P
ORDER BY LNAME; (WWV-08300)
Cursor is not open
Is this because of the multi-table queries, or something else? Is there any
way around this? Any information regarding this will be highly appreciated.
Thanks.

Sunny,
From the error message that you posted it seems that you are putting a semicolon ";" at the end of your query. I checked the query that you have posted. It is working fine for me. (I am using 3.0.8) but I feel it will work in your version also. I tried the query without a ";" at the end --It worked.
I tried with ";" at the end -- It gave the error that you have posted. So remove the ";" at the end and it should work. If you are still getting the same error then pls write down the version you are using. I will check in that version.
Thanx,
Chetan.

SQL Query works in SQL Developer, but not always in MII

Hi all,
I encountered a strange behaviour with a query in MII 12.0.2. Maybe someone has a guess what happens.
I have created a SQL query which runs against Oracle 10g tables. I have tested the query using SQL Developer, and it throws a couple of lines, depending on the contents of the where clause.
Next I have copied the query to a MII SQL Query (FixedQuery). However, the output is empty most of the time, without showing any errors. After some testing I got the impression that older data are not displayed, but there is no time or date setting in MII.
As the SQL Developer always returns rows, I am unsure where to search for the error.
Regards
Michael

Michael,
I would imagine that you have sub-select statements in your FixedQuery, all which will fall subject to the RowCount property of the query template (SQL defaults to 100), which is issued through the driver and typically honored by the database when returning the data from your request.
Most of the native database query tools allow you to make unbound query requests with no limit on rows, which would probably account for the difference between SQL Developer and the query template.
For SQLServer it's ROWCOUNT: http://msdn.microsoft.com/en-us/library/ms188774.aspx
For Oracle it's ROWNUM: http://www.oracle.com/technology/oramag/oracle/06-sep/o56asktom.html
So the answer would be not to make the query template row count some rediculous number, but more appropriately refine the way that the database request is issued.
Regards,
Jeremy

SQL Query Works in MS SQL Server 2008 but not when using Database Toolkit

I have this SQL query:
DECLARE @DataTypeTable TABLE (
Name varchar(128),
TypeID INT)
--Add comma delimeted data type names to temp table
INSERT INTO @DataTypeTable (Name)
SELECT * FROM WhatWeShouldDoRead.func_Split(@DataTypeTrimmed,',')
SELECT Name FROM @DataTypeTable
Which takes a comma delimited string and returns the string as a table. It works correctly in Microsoft SQL Server Management Studio. When I run this as a stored procedure I get back nothing. There are no errors, SQL or otherwise. I've verified that I am connected to the correct database and that the stored procedure is loaded by changing the no error string that is reported from this stored procedure (that code is not shown in the above example). Has anyone seen this problem before, or have any experiance with SQL/Labview interfaces to tell me what I'm doing wrong?
Thanks in advance.
Solved!
Go to Solution.

After doing some more research it appears that the database toolkit cannot interface with any table results from any type of temp table. It may have to do with the fact that MS SQL 2008 stores temp tables in a seperate database (tempdb) and not the database you are currently connected to. See this link for a good artical on temp tables:
http://databases.aspfaq.com/database/should-i-use-a-temp-table-or-a-table-variable.html
If possible, I'd like a someone to prove me wrong, but for now will have to settle for exporting the contents of a temp table through a string.

Why does Oracle SQL query returning a date field without the time component

Hi,
I'm a novice SQL user & hv just installed Oracle SQL developer (Version 3.0.04, Build MAIN-04.34).
I made the same SQL query using "Oracle SQL developer" & "TOAD for Oracle 9.0.1" but I got 2 different format on the same date field:
On TOAD, I get the date field extracted as *04/26/2011 23:12:58*
On Oracle, I get the date field extracted as *26/APR/11*
Why is the Oracle result in a different format & missing the time component?
Is there any option/preference that I need to set in Oracle SQL developer to get the full date/time format displayed?
I've tried to set my the date format to DD/MON/RR HH12:MI:SSXFF AM under the preference -> database NLS but I still get the same format!
Plse help!

Does the database have the object [MyTable]? What is the default schema for the user? Is the table (assuming it exists) in the default schema for the user?
Russel Loski, MCT, MCSE Data Platform/Business Intelligence. Twitter: @sqlmovers; blog: www.sqlmovers.com
Yes, the DB has the object [MyTable]. The default schema is dbo, as given by SELECT SCHEMA_NAME()
The table is in the default schema for the user as per -

Not sure as we don't have any tables and data to work with, but firstly...
a) format your code to make it easier to see what's going on
b) don't mix ansi joins with regular joins
c) treat DATEs as DATEs
d) Table alias names don't use the "AS" keyword
First guess (obviously unteseted)...

SQL query works for Access but not mySQL

*I'm using the Database Connectivity VIs* Can anyone give me a clue as to why the following query works with an MS Access File DSN but not a mySQL File DSN:
SELECT * FROM (SELECT * FROM WP100598 WHERE SerialNum LIKE '311022-05%' OR SerialNum LIKE '311022-07%') WHERE UTCTime > 1090882800 AND UTCTime < 1092870000 ORDER BY SerialNum desc
Thank you, your help is much appreciated

Hi,
I don't think MySQL supports nested queries.
