Min and Max values from entire table

Hi,
i have requirement in which i need to find the min and max values from the entire table.
See the sample data
create table test
Sal1 int,
Sal2 int,
Sal3 int
insert into test values (100,700,5700)
insert into test values (200,3300,5300)
insert into test values (4400,1200,3500)
insert into test values (5400,5600,3100)
i want the output as 100 and 5700.. how can i achieve this in a single query. Please through some light on this topic..!
Thanking you in advance

Below is an example with a subquery for each of the queries Mohammad posted in order to return both min and max in a single result set.
SELECT ( SELECT MAX(Maxx) AS Maxx
FROM test UNPIVOT
( Maxx FOR E IN ( Sal1, Sal2, Sal3 ) ) AS unpvt
) AS Maxx
, ( SELECT MIN(Minn) Minn
FROM test UNPIVOT
( Minn FOR E IN ( Sal1, Sal2, Sal3 ) ) AS unpvt
) AS Minxx;

hi there,
public class MinMax {

     int min, max;
     public MinMax() {
// it's very bad way to do it.
//          min=99999;
//          max=-99999;

Highlighting Min and Max Values on each line

Hello,
Is it possible to highlight the Min and Max values on each row of a Query. For example I have sales below by product line for the last seven quarters. The user
would like the Max value (150) for Product Line ABC Highlighted as Green and the Min value (1055) color coded as Red. Like wise for each line - DEF 200 as green and 100 as red and GHI - 400 as green and 100 as red.
FYQ Q207 Q307 Q407 Q108 Q208 Q308 Q408
ABC     1500     1200     1400     1050     1100     1100     1100
DEF     1550     1000     1560     1220     1340     1640     2000

Is this possible using Exceptions? or may be any other means? We are on Bex 7.0

Quality parameter -min and max values should be maintained w.r.to contract?

Hi all,
Min and max values in quantity contract should be maintained with respect to contract. till now we were maintaing min and max values with respect to inspection plans, but here since it differs for customer/vendor contracts - it need to be with respect to that. kindly suggest me on this
regards,
Soumya

In the Material Assignment TAB of the Inspection Plan Header, you can maintain or assign Vendor/Customer. These specifications will be assigned automatically for the Purchase Orders/Sales Orders for the Material/Vendor or Material /Customer Combination at Plant Level.
Check this and revert back.

Read the min and max occurrence from XSD

Hi,
I have a scenario where I have an XML, but not its XSD so my question is of two fold
1. Is it possible to create an XSD from that XML, if possible how?
2. Assume I get the XSD how do I read the min and max occurrence from that XSD?
PS: I am coding in java and pretty new to it, so it would be really helpful if I get the code snippets for the same :)

Medium, min, and max values on ALV

Hi friends ! How are are you ? Fine ?
How can i calc medium, min, and max values on ALV ?
Thanks !

Hi Fabrício
I think you set fieldcatalog at runtime dynamically to arrange dynamic columns. So, while you are setting it just set proper values to the attribute "do_sum" for relevant fields.
For more information how to set fieldcatalog dynamically, you can refer to the tutorial "An Easy Reference for ALV Grid Control".

OBIEE- Calculating Min and Max Values

Hi Friends,
I have an Issue with regards to calculating Min/Max Values.
In my Data base we dont have Message Count. So we created a Logical column in BMM Layer called "Message Count" based on the column "Out/In No" i.e by creating count of it i.e (Count(out/in no)) in BMM
To calculate Inbound Messages we writing -- filter(Message count using messagetype ='i') at report level
To calculate Outbound Messages we writing -- filter(Message count using messagetype ='o') at report Level
To calculate Total Messages we writing----- "Message Count".
But Now we had an issue to calculate "Min Inbound/Max Inbound/Min Outbound/Max Outbound/Avg In/Avg Out" types of Messages.
To make it clear definition for MIN and MAx is Like This.
Say Ravi received(Inbound) messages      2
Say Roy received(Inbound) messages      5
Say Kiran received(Inbound) messages   11 on a particular date.
So for that particular date Min Inbound is 2
So for that particular date Max Inbound is 11
and Avg Inbound will be (2+5+11)/3
On this basis we have to implement it in OBIEE. For any more clarifications please reply to my thread.
Please reply to my Issue ASAP as it is critical and I am out of time.
Thanks in Advance.

Hi,
Do you mean to ask minimum stock in a plant and maximum stock in a plant over a period of time?
Due to receipts stocks flows in to the storage location of a plant. May be in one period there will be less stock or in one period there will be maximum stock.
May be history tables like MBEWH or MARDH or the report MC.9 ( you need to provide the period as input) etc for your case.If this is not your requirement please reply back.

How to make validation in Bean and select value from another table

i want to know how to make this in a bean
i use jdeveloper 11g
and my project is ADF Fusion project

You might want to write this code in a validator on the entity object if it should apply from every screen.
If you want to access view objects from a backing bean the basics are here: http://download.oracle.com/docs/cd/E15523_01/web.1111/b31974/bcservices.htm#sthref918

How to show Min and Max values when another value "changes to a new value"

Hi
If I have this data (generated with this query: SELECT 1 A, 1 B UNION ALL SELECT 2, 1 UNION ALL SELECT 3, 2 UNION ALL SELECT 4, 2 UNION ALL SELECT 5, 1)
A B
1 1
2 1
3 2
4 2
5 1
How can I generate this data (created with this query SELECT 1 Amin, 2 Amax, 1 B UNION ALL SELECT 3, 4, 2 UNION ALL SELECT 5, 5, 1)
Amin Amax B
1 2 1
3 4 2
5 5 1
Thanks.

Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules. Temporal data should
use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
This is minimal polite behavior on SQL forums. You also do not know the ANSI/ISO syntax for insertion and you did the old Sybase insertion kludge wrong, that we need keys, etc.

This makes no sense; you have the wrong syntax and mixed data types. My guess is:
SELECT MIN(foo_seg), MAX(foo_seq), MAX(glop_score)
FROM Foobar
GROUP BY glop_score
HAVING MIN(glop_score) = MAX(glop_score);

Selecting a MAX value from a table & displaying it on a form using OCI PHP

WinXP Pro SP3- 32bit
Apache/2.2.22 (Win32) mod_fcgid/2.3.6 PHP/5.4.0
PHP Version 5.4.0
Oracle epxress 11g
problem: output on form displaying Resource id #4 instead of the number from the table.
(maybe it's number to string conversion issue?)
$conn = oci_connect('system', 'mypassword', 'localhost/xe');
$query = "SELECT MAX(CustNo)+1 AS MAXNUM FROM customer";
$stmt = OCIParse($conn, $query);
OCIExecute($stmt);
OCIFetch($stmt);
echo OCIResult($stmt, "MAXNUM")." will be next number.";
//OCIFreeStatement($stmt); //frees the resources- use a the end!
$daNextNo = $stmt;
echo $daNextNo;
//$daNextNo = OCIBindByName($stmt, ":text", &$form_text, -1); //not sure how this works if it'll fix the issue
?>
<form name="Addcust" action="process_cust.php" method="post">
<input type="text" name="CustNo" value="<?php echo $daNextNo;?>" /></br>
output of complete code:
45 will be next number.Resource id #4
And inside the textbox it says: 45 will be next number.Resource id #4
how can I put the 45 into $php variable so i can use it in a textbox or on a label?
Thank you in advance .

THanks. i couldn;t find the PHP section.
I figured it out
i used nextval() to convert the object to a string.
<?php
$conn = oci_connect('system', '1234', 'localhost/xe');
if (!$conn) {
$m = oci_error();
trigger_error('Could not connect to database: '. $m['message'], E_USER_ERROR);

//$daNextNo = $query;
$stmt = OCIParse($conn, $query);
OCIExecute($stmt);
OCIFetch($stmt);
echo OCIResult($stmt, "MAXNUM")." will be next number.";
//OCIFreeStatement($stmt); //frees the resources- use a the end!
$daNextNo = strval(OCIResult($stmt, "MAXNUM")." .");
$daNextNo = strval(OCIResult($stmt, "MAXNUM"));
echo "danextNo: ";
echo $daNextNo;

Export Waveform Chart Plots data to spreadsheet file based on X scale (Time Stamp) min and Max Value

Hi All,
Query 1:I am trying to export the Chart data(Total plots 6 ) only between the X scale Min Time and Max time limit .
But couldnt able to achieve that progammtically.
is their anyway to achieve this.
Query 2:Also ,In chart their is an right click option to export data to excel,but when using this option the data get exported in its own temporary name(iv*****.tmp),i dont want this to happen.Instead the data expored using that option should be written in a file specified by me(everyting should happen in backend)
pls suggest the best solution for above 2 queries.
Thanks,
Selvan.

Hi selvan,
1) read the chart history (or better keep a history in your own shift register) and limit the data to the XMin and XMax values (read all those chart settings from its properties). Then save the data using WriteToSpreadsheetFile…
2) The right-click option is as it is. When you need different behaviour you need to program your own routine. Once you finished query 1 it will be no problem anymore to also solve query 2…

Get old and new values from DBTABLOG table

Hi,
I am developing a report to display all changes to some fields of PKHD table over a date range. CDHDR & CDPOS do not capture the changes while DBTABLOG does. But the variable key field (LOGDATA) in DBTABLOG does hold encrypted values which need to be decrypted. Is there any FM or a way out to get them ?

Single result recording valuation based on min and max values

hi,
Our client requirement is as follows:
While entering the single results recording the system should not calculate the average , we need the system should valuate based on the Minimum and Maximum values in result entry. Is it possible?. can anyone explain in details.
Regards,
Ramu.

Hi
This is a standard SAP functionality available in SAP
As
Variable Inspection by S-Method
If you set this indicator, you define the valuation mode for the variable inspection according to the s-method (ISO 3951).
For a sampling procedure with this valuation mode, valuation occurs using a sampling plan consisting of sample size and k-factor. A quality score is calculated from the measured values of a sample and compared with the k-factor.
Now you want Both limits should come into picture while valuating then Check valuation Rule :31 -Variable insp. s-Method (two limits)
so select the Valuation mode : 310- Variable insp. s-Method (two limits) in sampling procedure.
I hope this will add some value.

Selecting Max Value from Huge Table

Dear Proffessionals
I have a huge table (20,000,000+ records) with the following columns:
[Time], [User], [Value]
The values in [Value] column can recur for a single User at a Time e.g.
2015-01-01, Me, X
2015-01-01, Me, Y
2015-01-01, Me, X
2015-01-02, Me, Z
2015-01-02, Me, X
2015-01-02, Me, Z
For each day, and for every user I want to have the maximum recurring value :
2015-01-01, Me, X
2015-01-02, Me, Z
to be inserted into another table.
PS: I want the MOST optimized way of achieving this functionality, bcause I am expecting a growth on the raw table over time, so PERFORMANCE is of great consideration.
I would really appreciate it, if somebody can help me.

I can think of two techniques based on the data selecticity
1) using row number function
2) using cross apply operator
USE Northwind;
-- Solution 1
SELECT S.SupplierID, S.CompanyName, CA.ProductID, CA.UnitPrice
FROM dbo.Suppliers AS S
CROSS APPLY
(SELECT TOP (10) *

ORDER BY UnitPrice DESC, ProductID DESC) AS CA
ORDER BY S.SupplierID, CA.UnitPrice DESC, CA.ProductID DESC;
