eBooks on SQL query optimization

Hello.

can someone assign me all the technical links for ebooks on tuning SQL query to 10g or 11g.

Tuning SQL queries, it's something I want to build my expertise...

There may be many consultants as the query SQL, Access Advisor Advisor and so on... but nothing of such adjustment your queries manually for maximum optimization.

Kindly help me in this!

Check Oracle docs http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/toc.htm

But really, you should also check:

http://www.asktom.Oracle.com

http://tkyte.blogspot.com

AND all the other blogs he does (like Jonathan Lewis site and blog) you will find many interesting articles there, the 'real world', regarding performance and optimization.

What is the best way to optimize a SQL query: call a function or doing a join?

Hi, I want to know what is the best way to optimize a SQL query, call a function inside the SELECT statement, or make a simple join?

It depends on. Could be a. Could be the other. Could be no difference. You would need to compare with your tables in your environment with your settings.

If you put a gun to my head, I was given no other information and required that I answered the question, I would tend to wait that the join would be more effective. In general, if you can do something in pure SQL, it will be more effective than if you call PL/SQL.

SQL Query - store the result for optimization?

Good day experts,
I'm looking for advice on a report. I did a lot of analytical functions to get the basic data that I have to do my report and its takes about 50 min for SQL finish. Now, with these data, I need to create 3 different reports and I can't use the SQL even since there are a lot of aggregation (example would be product group in one case and by customer in 2nd). For each of these different group garages I need another report.
So how to create 3 reports of 1 SQL query without running the query 3 times?
First thing that comes to mind is to store the result set in a fictitious table, and then query the table since I get the basic data are about 300 lines and then perform different garages group.
Best regards
Igor

So how to create 3 reports of 1 SQL query without running the query 3 times?

You already know the obvious answer - store data 'somewhere '.

If any 'somewhere' depends on your needs and you have not provided ALL the.

MV - if the query is always the same, you might use a MV and make a complete refresh when you want that new data. The data are permanent and can be queried by other sessions, but the query that accesses the data is frozen in the definition of MV.

GTT (global temporary table) - If a NEW charge of data AND three reports will be ALWAYS executed by a single session and then data are no longer necessary so a TWG may work. The application that loads the TWG can be different for each race, but the data won't be available for a single session and ONLY for the duration of this session. So if something goes wrong and the session ends the data are missing.

First thing that comes to mind is to store the result set in a fictitious table, and then query the table since I get the basic data are about 300 lines and then perform different garages group.

Which is commonly called a "table of REPORT-READY." Those that are useful when data must be permanent and available for multiple sessions/users. Generally, there is a batch (for example the package procedure) that periodically refreshes / updates the data during a window of failure. Or the table can have a column (for example AS_OF) that allows it to contain multiple data sets and the update process let alone the existing data and creates a new set of data.

If your database is about 300 lines you can consider a table report and even use it to contain multiple data sets. Then, the reports can be written to query the data by using a value AS_OF that wraps and returns the appropriate data. You don't need a window of failure since the oldest data are still available (but can be removed when you no longer need.

If you need a set of data, you can use a partitioned table work (with only one partition) to collect the new set of data, then a SWAP PARTITION to 'swap' in the new data. Only, this "Exchange" takes a fraction of a second and avoids a window of failure. Once the swap done no matter what user query will get new data.

Need help to reduce the cost of my sql Query below 100 to optimize.
Can you please suggest how to reduce the COST of my SQL query? Is it possible to get the < 100 COST?

String separated by commas to 'IN' operator in SQL query

Hello
The issue is that the "In" operator in the report query accepts values contained in the element of page Apex... 221,332,542.
Is there a common solution for this problem?
Thank you
Patrick

It's the common "variable list" model [anti-]. In
```
select * from table where columnvalue in (7788, 7839, 7876)
```
(7788, 7839, 7876)is a list of expressions and the predicate is evaluated as a membership condition.

In
```
select * from table where columnvalue in :P1_X
```
:P1_Xis a scalar string, unable to contain multiple values.

In a report of type APEX, a source report of the body of the PL/SQL function returning a SQL query with lexical substitution can be used to produce a "variable list:
```
return 'select * from table where columnvalue in (' || :P1_X || ')';
```
where P1_X contains less than 1000 values, has been disinfected to code SQL injectionand string values are properly cited.

Some people suggest the following approach, that will work also in interactive APEX reports:
```
select * from table where instr(':' || :P1_X || ':', ':' || columnvalue || ':') > 0
```
However, it is underperforming because it eliminates the possibility of using the index optimizer or the size of the partition in the execution plan.

See various elements in the list to ask Tom and imitating the channel to the table using sql features for effective solutions.

Hello

It is not necessary to display the trace file - everything is clear from the plans that you have posted. The optimizer is the selectivity calculation assuming the absence of correlation between the columns. You can do these calculations that yourself and you see that if the entries are correct and if the hypothesis of lack of correlation is also correct, then the results should be correct, too. Since they are not, it's one of two things: optimizer stats are wrong, or the columns are in fact related.

First of all check the optimizer statistics: i.e. take NUM_ROWS and NUM_NULLS of DBA_TAB_COL_STATISTICS and compare them with the actual rowcounts. If they are correct (in a reasonable error margin), then it means that the columns are correlated, and the optimizer will need additional assistance to obtain right of cardinalities.

Œuvres SQL query to MS SQL Server 2008, but not when you use the database kit

I have this SQL query:

DECLARE TABLE (@DataTypeTable)
Name varchar (128).
TypeID INT)

-Add comma delimeted type data in the temporary table names
INSERT INTO @DataTypeTable (name)
SELECT * from WhatWeShouldDoRead.func_Split (@DataTypeTrimmed, ',')

SELECT the name OF @DataTypeTable

That takes a comma delimited by the 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 return nothing. There are no errors, SQL or otherwise. I checked that I am connected to the correct database and the stored procedure is responsible without changing any error chain which is reported of this stored procedure (that code is not shown in the example above). Has anyone seen this problem before, or have experience with SQL/Labview interfaces to tell me what I am doing wrong?

Thanks in advance.

LabVIEW sql query

HI HI... I'm a student doing a project related to labview. My task is to create a vi, type a user name and password to continue the whole VI.

As I am a newbie to SQL query language, can anyone help me this?... This isn't like the VI with password lock

There is a connection of the user called button in my main façade... u by clicking on it, a pop-up window will come out asking you a user name and a password. If the user name and the password is correct, then you can proceed. The problem is that I'm stuck with database...
Help me pls!

with respect,

Ray

Hello

You have two cases:

(1) connect to the database with string (link a string of connection information), and then type something like this:
Driver is SQL Native Client;. Server = IP. Add.re.SS; UID = username; PW = *** ; Database = MyDatabase (depends on your database)

(2) use a UDL file (you can configure it to connect to your database, with specific format). Remember that the connection is successful with test button.

There is a UDL file that you can edit here: C:\Program NIUninstaller Instruments\LabVIEW 2010\examples\database\Labview.udl

Edit: The connection dropped, you can set the path to an mdb file, and I think you can give the path of your accdb file.

Kind regards

SQL query for empty string

I am trying to execute the following SQl query, SELECT * failure WHERE ID = '123 ' AND RepairAction =' '; using the DB tools run Query.vi. This query never find record in my database. My database contains a record where the registered ID contains the value '123' and the RepairAction field is an empty string. If I remove the declaration 'AND RepairAction' ';' my query text, the record is found. I think my problem is that I do not use the correct syntax to describe and an empty string. I tried the following: "," ",""," "and NULL as empty and none of these work string arguments.

I was hoping someone might be able to tell me what the correct syntax is an empty string or if there is another approach that I take.

Thanks in advance for your help,

Jim

Jim,

Just to be sure, have you used 'is' instead of '=' in this command?

This makes all the difference in this command.

Support of SQL query: what tasks are Sunday from 07:00 - 12:00

Hello tide Admins.

I need to do a SQL query that can give me a list of jobs that are running on a given (Sunday) day from 07:00 - 12:00. Our environment is not a maintenance window. Therefore, whenever there is application of patches or upgrades, it causes more work and risk of failure of the tide tasks. By moving jobs over the period from 07:00 - 12:00 Sunday, patch can be completed without disrupting the calendar.

Im not the best at the SQL script and can not get my script to work. any help would be great. Here's what I have so far. I get the error ' could not find identifier multi-player jobmst.jobmst_name. IM using Tidal 6.0.3 with SQL for DB Admeral table.

SELECT dbo.jobdtl.jobdtl_id, dbo.jobmst.jobmst_prntname, dbo.jobmst.jobmst_name

FROM dbo.jobdtl INNER JOIN

dbo.jobmst ON dbo.jobdtl.jobdtl_id = dbo.jobmst.jobdtl_id

WHERE (dbo.jobdtl.jobdtl_fromdt > 14 September 2016 06:00 ') AND (dbo.jobdtl.jobdtl_fromdt< '09/11/2016="" 012:00:00="">

GROUP OF dbo.jobdtl.jobdtl_id, dbo.jobmst.jobmst_prntname, dbo.jobmst.jobmst_name

Hi Jeff

The time window from the jobdtl returns only jobs that have an early start time and windows of time from beginning to the end, so there may be some tasks which are not time bound but have dependencies on other jobs, variables, etc.

Here are the 2 SQL queries against the table jobrun and jobmst:

-The list of jobs that took place last Sunday between 07:00 and 12:00

SELECT jobmst.jobmst_prntname, jobmst.jobmst_name, jobrun.jobrun_time FROM jobrun
JOIN jobmst on jobrun.jobmst_id = jobmst.jobmst_id
WHERE jobrun.jobrun_time > = 9/11/2016 07:00 ' and jobrun.jobrun_time<= '9/11/2016="" 12:00="">
ORDER BY jobrun.jobrun_time

-For a list of jobs that are scheduled to run on Sunday to come between 07:00 and 12:00

SELECT jobmst.jobmst_prntname, jobmst.jobmst_name, jobrun.jobrun_esttime FROM jobrun
JOIN jobmst on jobrun.jobmst_id = jobmst.jobmst_id
WHERE jobrun.jobrun_esttime > = 9/18/2016 07:00 ' and jobrun.jobrun_esttime<= '9/18/2016="" 12:00="">
ORDER BY jobrun.jobrun_esttime

How to get the value of a column in sql query?

Hi, anyone knows how to get the value of a column in sql query?

Here is my code, the value must be 1350079224397 in my PB, but I get 0

QString query ("SELECT version FROM db_version");

QVariant result = sda.execute (query);
QVariantMap versionMap = result.toList () such () .toMap ();
If (! versionMap.IsEmpty ())
{
qDebug()<"Version: "=""><>
}

OK, I have the solution

QString query ("SELECT version as version FROM db_version");

Looking for a SQL query to retrieve callvariables + ECC to a RESULTS of SCRIPT EXECUTE (translation VRUS)

Hi team,

I'm looking for a SQL query check data (ECC + CallVariable) due to a RESULT of SCRIPT EXECUTE when you ask an external VRU with a translation route to VRU with a 'run external Script '.

In my view, that the data are analyzed between the termination call detail + termination call Variable.

If you have already such a SQL query I would be very grateful to have.

Thanks and greetings

Nick

Omar,

respectfully, shorten the interval of a day might not be an option for a history report ;-)

I recommend to take a look at the following SQL query:

DECLARE @dateFrom DATETIME, @dateTo DATETIME

SET @dateFrom = ' 2014-01-24 00:00:00 '

SET @dateTo = ' 2014-01-25 00:00:00 '

SELECT

TCV. DateTime,

TCD. RecoveryKey,

TCD. RouterCallKeyDay,

TCD. RouterCallKey,

VME. EnterpriseName AS [ECVEnterpriseName],

TCV. ArrayIndex,

TCV. ECCValue

OF Termination_Call_Variable tcv

JOIN THE

(SELECT RouterCallKeyDay, RouterCallKey, RecoveryKey IN Termination_Call_Detail WHERE DateTime > @dateFrom AND DateTime)< @dateto)="">

THE tcv. TCDRecoveryKey = tcd. RecoveryKey

LEFT OUTER JOIN Expanded_Call_Variable VME ON tcv. ExpandedCallVariableID = VME. ExpandedCallVariableID

WHERE the tcv. DateTime > @dateFrom AND tcv. DateTime<>

With variables, you can set up your code (for example, you could write SET @dateFrom =? and let the calling application to fill in the DateTime for you).

In addition, join two large tables with all the lines, as you did (TCD - TCV) is never a good option.

Another aspect to consider: all the ECC is actually arrays (always), is not good to leave aside the index value (tcv. ArrayIndex).

DA on updatable report items Sql query using the class

Request Express 4.2.5.00.08
10-11 g Oracle
I have a page, so it has a link/button when he clicks then modal region will appear. Modal region has a as a table (Type SQL Query (updateable report)). All work very well so far.

However, I've now added some complex things.
for example. My region is based on the query of SQL Type (editable report).
SELECT id, name of family, Traghetti, area, d_date, start_time, End_time, displacement, role of table where id =: P10_ID;
I can also add a new line of course.
My problem is, (point) Shift display based on the value of Start_Time point) and so I made sure the class for two items.
for example, Start_Time (' class = "st_tm" ') and Maj ('class to = "Shift_time" '). Start_Time is based on (LOV) and shift is off the point in the sql query, but change the Start_Time.
And now, I created the DA.
1. event: change
Selection type: jQuery Selector
jQuery Selector: .st_tm
Condition: No.
1. action: set value
Set type: Expression Javascript
The JavaScript Expression: $(this.triggeringElement) .val ();
The element affected: P10_X1 (it is a hidden item)
2. action: Plsql Code
Code: start to null; end;
Page items to submit: P10_X1
3. action: Plsql Code
Code: start
If: P10_X1 between '03' AND '11' then
: P10_X1: = 'EARLIES ';
elsif: P10_X1 then '12' and '18'
: P10_X1: = 'LATES ';
on the other
: P10_X1: = 'NIGHTS';
end if;
end;
Page items to submit: P10_X1
NOW another DA
Event: change
Article (s) P10_X1
Condition (in list)
value (HASTY, LATES, NIGHTS)
Action:
Set type: Expression Javascript
The JavaScript Expression: $(this.triggeringElement) .val ();
Affected item:
Selection type: jQuery Selector
jQuery Selector:. Shift_time
Well, I look forward all the above work well, but I'm having a problem.
If I have more than 1 lines on a modal region and if I change the Start_Time value for a row then MAJ (point) is changing but he effect on all lines.
I want, if I make the changes on the line line # 2 while only 2 # MAJ (point) must be not performed any other lines?
Help, please!
Kind regards
RI

I found the solution me thank you.

I removed all the DA mentioned above and created a new.

1. event: change

Selection type: jQuery Selector

jQuery Selector: .st_tm

Condition: No.

Scope of the event: dynamic and light on page load.

Action (Javascript code)

ROW_ID = $(this.triggeringElement).attr('id').substr (4);

If ($(this.triggeringElement). val() > = 03 &. val() $(this.triggeringElement))<= 11)="">

.Val ('EARLIES') $(«#f11_» + row_id);

}

ElseIf ($(this.triggeringElement). > 11 val() & $(this.triggeringElement). val())<= 18)="">

.Val ('LATES') $(«#f11_» + row_id);

}

ElseIf (. val() > $19 (this.triggeringElement)) {}

.Val ('NIGHTS') $(«#f11_» + row_id);

}

also created another DA because I have a disabled report items.

Event: before the page is sent.

$('_:_disabled').removeAttr ("disabled");

and finally created manual process of DML for tabular and everything works fine. (Insert, Update, and delete).

Kind regards.
