Min and max functions

Hi,
I need to perform a calculation:
(max(min(C,2.375),0)+max(min(Y,2.375),0))/6
if the value of c is less than 2.375 then it has to accept the value of C else 2.375.
on it i need to perform the max operation.
How can i do this?

Hi,
MIN and MAX, like all the aggrgate functions, take only one argument.
Perhaps you're thinking of the row functions LEAST and GREATEST, which can take one or more arguments.
For example:
GREATEST ( LEAST ( c
                 , 2.375
         , 0
         )will return
2.375 if c is greater than 2.375,
0 if c is less than 0, or
c otherwise.
CAUTION: Unlike the aggregate functions, that ignore NULLs, GREATEST and LEAST will return NULL if any of their arguments are NULL.

Using Min and MAX function on Bit Field

Hi All,
I am trying to write a SQL Query where i want to aggregate a bit field along with some other numerical fields
I have a Field of type Bit and it can contain data like
Scenario 1: MyBit Field
Row1 Null
Row2 Null
Row3 Null
Scenario 2: MyBit Field
Row1 1
Row2 1
Row3 Null
Scenario 3: MyBit Field
Row1 0
Row2 0
Row3 Null
Scenario 4: MyBit Field
Row1 1
Row2 0
Row3 Null
Scenario 5: MyBit Field
Row1 1
Row2 1
Row3 0
Scenario 6: MyBit Field
Row1 1
Row2 1
Row3 1
Scenario 7: MyBit Field
Row1 0
Row2 0
Row3 0
These are all scenario i can think of, i want to have sql statement which should return me
null if all values are null,
if there is mix of 1, 0 then return NA,
if there is mix of 1,0,null return NA
if there is mix of 1's with Null then return 1 ,
if there is mix of 0's with null return 0 ,
if there is all 0's return 0
if there is all 1's return 1
IS there an elegant way in SQL to handle this
Note : I have other fields in query which are simply getting SUM.

Try:
DECLARE @T table (

Avg, Min and Max with a serious twist.....ASO

Hi,
I need to calc the Avg, Min and Max on Revenue. That's simple. However Every row of data the revenue falls into a bucket/range. For example revenue is in buckets '0 to 50' or '51 to 100' or '101 to 150' lets say. As I load data I load a '1' into a 'Count' measure depending on which bucket that row of data falls into. So I can get a total count for each bucket. So '0 to 50' might have a Count of 3. '51 to 100' might also have 3 and '101 to 150' has a 2. So my range count looks like:
0 to 50 - 3
51 to 100 - 3
101 to 150 -2
The trick is they only want the Avg, Min and Max on the rows that makeup the highest 'Count'. In this case that's 3. Problem is there are two ranges that meet this criteria. When that happens they want the Min, Max and Avg of the rows that make up the '51 to 100' bucket since it's the highest range.
I can easily get the '3' by using the Max formula. So I know what the highest bucket is. Problem is I can't figure out for the life of me, how to pass only those rows that make up the '51 to 100' bucket into the Avg, Min and Max function.....
I'm stumped and in dire need of something here. I have a spreadsheet that explains the problem better. If somehow I can get a flag on those rows I can easily Avg, Min and Max it. I just can't seem to figure out how to get a flag on only those rows of data.
I'm willing to share my mocked up example and spreadsheet and .otl and sample data etc....
Please help :)

Why does this verify with Min?

Find more than one min and max in 2D array contain 0 rows

Hi
I have a 2D array and I would like to find the max and min elements between series of 0s. As you can see in the picture If I remove all 0s from the array and use the max and min function then I will have just one min and one max but I need to find min and max after every 0 rows so you can see from the picture ( just as an example) I will have 3 min and 3 max numbers. Would you please help me with this code. Do you now any algorithm that can find min and max between 0s?
I have also attached my code to remove 0s and then search for max and min numbers but as I mentioned I need min and max for every part
Many thanks

Thanks altenbach
I have attached the vi to this post. I would really apperciate if you help me with this example. The min values should be 100, 1500 and 4000 and the max values should be 1200,2600,5400 so as u mentioned the output should be this 2D array
100,1200
1500,2600
4000,5400

Min and max constraints

In my database design and implementation module I'm at the implementation stage. I've set up all of my tables with PK and FK constraints and I'm wondering if you can enforce min and max column constraints. One of the rules of my DB is for my staff table there has to be a minimum of 10 and a maximum of 50, how would I enforce this rule as a constraint on the staff table or isn't this possible?
We have only been learning database design and SQL fundamentals so I don't think I'd be allowed to use triggers or procedures.
Many thanks
Mike

thanks guys these commands were accepted

Thing is my staff_id's are in the format 'S110001' will these constraints only check for integers 10 - 50? maybe I need to use a count function on the column or something?
thanks again for your help!
MikeCheck constraint can also be used to check a list of values.
example:
ALTER TABLE <table_name>
ADD CONSTRAINT <constraint_name>
CHECK (<column_name> LIKE <condition>);
ALTER TABLE <table_name>
ADD CONSTRAINT <constraint_name>
CHECK (<column_name> NOT LIKE <condition>);
ALTER TABLE <table_name>
ADD CONSTRAINT <constraint_name>
CHECK (<column_name>
IN (<comma delimited list of values>);
ALTER TABLE <table_name>
ADD CONSTRAINT <constraint_name>
CHECK (<column_name>
NOT IN (<comma delimited list of values>);
ALTER TABLE <table_name>
ADD CONSTRAINT <constraint_name>
CHECK (<column_name> BETWEEN <lower_value>
AND <higher_value>);
ALTER TABLE <table_name>
ADD CONSTRAINT <constraint_name>
CHECK (<column_name>
NOT BETWEEN <lower_value> AND <higher_value>);
ALTER TABLE <table_name>
ADD CONSTRAINT <constraint_name>
CHECK (<column_name>) > (<condition>);

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.

Capturing min and max of a func. generated sine wave

I need to identify (in real time) the min and max values of a continuous sine wave (whose amplitude may vary). I need to capture the value of each min and max and the time of each such occurrence.

If the sine wave is in the form of a waveform data type, then all you have to use is the Waveform Min Max function. This does all that you want including returning the time values. There's even an example under Help>Fundamentals>Waveforms>Waveform Operations.

Difference of value of a dimension based on min and max

Database: Oracle 10g
BO-BOXIr3
Let me explain the exact problem again.
As per the below code, I have the data in this format in my table:
Code:
Date              Site ID     KWH
1/2/2009 00:00     IN-1     22
1/2/2009 01:00     IN-1     28
1/3/2009 03:00     IN-2     25
1/3/2009 04:00     IN-2     46
1/4/2009 00:00     IN-3     28
1/4/2009 10:00     IN-3     34
1/5/2009 08:00     IN-4     31
1/5/2009 09:00     IN-4     55
1/5/2009 11:00     IN-4     77
1/6/2009 00:00     IN-5     34
Now want to build a report with following columns:
Site     Count     KWH
IN-1     2     6 (ex.-28-22)
IN-2     2     21
IN-3     2     6
IN-4     3     46 (ex.-77-31)
IN-5     2     34
SITE- distinct site name.
COUNT-count is number of repetitions of site id between min and max date.
KWH -(Delta between the min and max date)
To get the above result I have created 3 report from different queries since not able to get these al in a single report viz Count, Max Value and Min value. Well I have all these 3 reports or table on a single page.
Count-this report will give the count between the dates
Max Value-this report will give me the values of kwh for max dates for each site id
Min Value-this report will give me the values of kwh for min dates for each site id
Now want to create a single report based on these 3 reports which contains the column
Site|Count|KWH
IS IT POSSIBLE?
Or
Is it possible to build such report in a single one with all the required column which I mentioned?
The variables which I created to get the max & min dates,
Mx_dt= =Max([Query 2].[Hourly]) In ([Query 2].[SITE_ID])
Mn_dt= =Min([Query 3 (12)].[Hourly]) In ([Query 3 (12)].[SITE_ID])
For filtering on report used following variables:
if_st_mn=If([mn_dt])=[Hourly] Then "ok" Else "no"
if_st_mx =If([mx_dt])=[Hourly] Then "ok" Else "no"
will filter on "ok" to get the max and min date values.
rest of the variable in the snap are not usable.

Yes, you can do it in one report.
I created a sample report from efashion:
Year | Lines | Sales Revenue
2001 | Accessories | $250
2003 | Accessories | $550
2001 | City Skirts | $1050
2003 | City Skirts | $1150...........
Create 2 variables 1) Count and 2) Difference:
1) Count as formula - =Count([Lines]) In Report
2) Difference as formula - =Sum([Sales revenue]) Where (Max([Year]) In Report = [Year]) - Sum([Sales revenue]) Where (Min([Year]) In Report = [Year])
You can replace the formula with your report variables. Then just drag Site ID, Count and Difference variables to your report.
Thanks

After installing Version 5 I get an error message about incompatibility and min and max versions.

I shutdown Zone Alarm, and deleted the contents of the file, which contained the "exe" file, then reinstalled Firefox version 5.0. I still get the XUL Runner error message about incompatibility of Version 5.0 with min and max 5.0.1. What next?

The updater wasn't able to update all the files and some were left as older versions.<br />
You need to do a clean reinstall.
Download a fresh Firefox copy and save the file to the desktop.
* Firefox 5.0.x: http://www.mozilla.com/en-US/firefox/all.html
* Uninstall your current Firefox version.
* Do not remove personal data when you uninstall the current version.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

Performance Issue using min() and max() in one SQL statement

I have a simple query that selects min() and max() from one column in a table in one sql statment.
The table has about 9 Million rows and the selected column has a non unique index. The query takes 10 secs. When i select min() and max() in separate statements, each takes only 10 msecs:
This statement takes 10 secs:
select min(date_key) , max(date_key)
from CAPS_KPIC_BG_Fact_0_A
where date_key != TO_DATE(('1900-1-1' ),( 'YYYY-MM-DD'))
This statement takes 10 msecs:
select min(date_key)
from MYTABLE
where date_key != TO_DATE(('1900-1-1' ),( 'YYYY-MM-DD'))
union all
select max(date_key) from MYTABLE
Because the first statement is part of an autmatic generated SQL of an application, i can't change it and i have to optimize the data model. How can i speed up the first statement?

I've ran similar query on a table that has 10 milliion rows, with an index on the date column
This is what I have found:

Formula for MIN and MAX per range required in BW

Good day
Please assist with the following? I need to create a formula (CKF) in BW Query which will give me the same result as the following formula in Excel.
What I have is one Key Figure and want to calculate a Score on that key figure.
Score =Key figure/(MAX(range of ie. column B1 to B50 which contains data for the same KF)-MIN(range of ie. column B50 which contains data for the same KF).
In excel it's easy, ie" Score =TD completed/(MAX(B28:B130)-MIN(B28:B130)
If more information is required to assist, please let me know?
Always appreciated.
Cornelius

Thank U so much for responding so fast.
I did the MIN and MAX formula, but it is only taking the MIN or MAX from the single cell of the applicable key figure and not from a 'range' of cells. This is a further example of what I want to do:
Cell: B1 = 10
        B2 = 12
        B3 = 15
        B4 = 0
I want to display the MIN as '0' and the MAX as '15' and then do the calculation per row.
We are in 3.2x. I want to stay away from structures as I have not done that before.
Any other assistance will be highly appreciated.

Global Change or filter based on Min and Max dates

Hi Guys,
Hopefully there is a genius out there that is an expert with filters and or global changes, I am after a solution and can’t work out if it is possible to do in P6.
Based on a filter (using codes to select a group of activities) I want to write a value into two date UDF Fields can I:
Run a global change to give the earliest and latest date in the group and write the result to all tasks in the group? or
Is there a mindate maxdate option in Global change or filter? Or
If these tasks were grouped in the activity view can a global change be written to fill down the dates that the summary level is displaying, which are essentially the min and max dates of the groups.
I could do this pretty easily in excel but I have over a 100 projects and doing the import one at a time is not feasible.
I could create LOE’s but as my variables are constantly changing and due to the volume also not an option.
Summary bars are not an option eithers as I am writing the UDF’s to get all the bars I want on one line,
An option for me might be to do it using Legare but I would prefer to see if I can get it done in P6 first.
Cheers
Rob

Yes, you can do it in one report.
I created a sample report from efashion:
Year | Lines | Sales Revenue
2001 | Accessories | $250
2003 | Accessories | $550
2001 | City Skirts | $1050
2003 | City Skirts | $1150...........
Create 2 variables 1) Count and 2) Difference:
1) Count as formula - =Count([Lines]) In Report
2) Difference as formula - =Sum([Sales revenue]) Where (Max([Year]) In Report = [Year]) - Sum([Sales revenue]) Where (Min([Year]) In Report = [Year])
You can replace the formula with your report variables. Then just drag Site ID, Count and Difference variables to your report.
Thanks
Jai

MIN and MAX datetimes ti find range

I am using Oracle 11g version
create table re(Name char(20),Datetime char(45),val1 number);
insert into re values('abc','10/29/2012 13:00','1.5')
insert into re values('abc','10/29/2012 13:05','1.5')
insert into re values('abc','10/29/2012 13:10','1.5')
insert into re values('abc','10/29/2012 13:15','1.5')
insert into re values('abc','10/29/2012 13:20','0.00')
insert into re values('abc','10/29/2012 13:25','0.00')
insert into re values('abc','10/29/2012 13:30','0.00')
insert into re values('abc','10/29/2012 13:35','0.00')
insert into re values('abc','10/29/2012 13:40','2.1')
insert into re values('abc','10/29/2012 13:45','2.3')
insert into re values('abc','10/29/2012 13:50','2.1')
insert into re values('abc','10/29/2012 13:55','2.1')
insert into re values('abc','10/29/2012 14:00','2.2')
O/P:
In this way data is stored in database.Needed output is, I want the datetime column data range with min and max values where val1>0 only.
Expected result while we consider the above data is::
Name mintime maxtime
abc 10/19/2012 13:00 10/19/2012 13:15
abc 10/29/2012 13:40 10/29/2012 14:00
For this I tried something like this,
select name, min(to_date(Datetime ,'mm/dd/yyyy hh24:mi')) start, max(to_date(Datetime ,'mm/dd/yyyy hh24:mi')) end from (
select name, Datetime ,to_date(Datetime ,'mm/dd/yyyy hh24:mi') - rank() over (partition by loc_name order by t1 asc) Val_col from re where val1 > 0
) group by lname, Val_col
but I am getting the output like this for above query.
name start end
abc 10/29/2012 13:00 10/29/2012 13:00
abc 10/29/2012 13:05 10/29/2012 13:05
so.on.

so.on.Firstly and most importantly do NOT store dates as char columns: that's what the DATE type is for.
Secondly, i'm not sure how you get your output from the input, particularly as your SQL contains 'partition by loc_name' which
doesn't even exist in your example table.
Why has the same name got two rows with those min/max times. Are you partitioning by val1?
