Description string based on a formula

I am stumpped,
I am trying to write a formula so that I can return a description string from a database. My database is structured poorly so I will try to explain it as best I can. The collumns that are of intrest are my CA1 collumns which has all of my project numbers like 10230000.1 the next collumn is the WP which has an extention of the number or is blank the number looks like 10230000.100 or it is blank the next collumn is the description. I want the description to be printed when the WP is blank. I have my report grouped by the project number then by what we call the cost account (CA1) the next logical level is the work package (WP) but it is not in the report and is not needed when the WP data is blank the description collumn has the cost account description in it. Here is the formula that i have been playing with.
WhilePrintingRecords;
if{CAWP.WP}="" then {CAWP.DESCRIP} else "No Cost Account"
but i get a no cost account all of the time
any thoughts?

Hi,
IsNull(Fld) mayn't work because some database dosen't support null values;This function will not work if the active database(s) do not support null values
Note: Zero and blank (empty or " ") are not null values
Try with keyword HasValue(fld)
Please check the use and apply to your function.also what are the data types you are using for these fields ?
Hope it works
Thanks

Item based on a formula in a custom folder

Hi, actually I'm using Discoverer 4i and I have a problem when I create (with the administrator) an item based on a formula inside a custom folder.
The item is based on the following formula :
GET_THRESHOLD(Name,'XXI_SZF_SLA_Thresholds_Kormos') -- (1)
where:
GET_THRESHOLD is a function that returns a number
Name is the first parameter (and at the same time another item of the custom folder)
'XXI_SZF_SLA_Thresholds_Kormos' is an hardcoded value.
So..when I wrote the formula into the Item Properties, this is written correctly and when I connect with Desktop or Viewer my report works correctly.
But when I close and I re-open the administrator, I see the following formula
GET_THRESHOLD(Name,'XXI') -- (2)
.....how it was saved in a wrong way....or truncated....
I tried to check also the flag "Automatically save changes after each edit"....but I see always, after I reopened the administrator, the formula (2) and not the formula (1)
Is seems that my changes are not saved !!
Is this a bug ? Can I fix it in some way ?
Thanks in advance
Alex

hi,
1. Try to execute the function manually by passing the same value.
2. Discoverer formats the names of Items/folders/parameters etc by replacing underscores ("_") with a space, so this might be the reason, why it converts the value to : 'XXI SZF SLA Thresholds Kormos' and takes only the first string "XXI".
3. Try passing a value without "_".
Hope this helps!

How do I create a dynamic parameter based on a formula?

Hi,
I've developed a report, in CR 11, that is parameterized based on the field "ticket_date". I've created a Min and a Max formula so that I can select a date range. This works wonderfully. However, my date list is growing longer by the day and each day I have to run the report I need to scroll through an even longer list of date values. This will become increasingly impractical with each passing month and year. I would like create a "Year" paramater and a "Month" parameter so that I can first select the Year, then the month(s), then the dates.
When I attempted to create a parameter based on the formula, "Year (), the formula wasn't in the list of available values to create a parameter on.
How can I address this requirement?
thanks in advance!
Mark

Hi Abhilash,
Looks like I was able to create a Year field in the Command - thanks for the tip!
Before I close this off as answered can you take a look at two sets of SQL I wrote in the Command that I'm getting errors on and offer advice on where the error is occurring.
Example 1
The SQL I attempted to write must be close though:
Select ft.sequence, ft.ticket_date, coff.office_name, comp.subscriptions_id from
field_tickets as ft, company_offices as coff, companies as comp
INNER JOIN jobs ON comp.companies_id=jobs.companies_id
INNER JOIN field_tickets ON jobs.jobs_id=field_tickets.jobs_id
LEFT JOIN company_offices ON jobs.company_offices_id=company_offices.company_offices_id
Where comp.subscriptions_id=7.00
When I attempt to save this I get an error:
"Failed to retrieve data from the database. Details: Exception: Error Message: Java Heap Space"
Example 2
I get the error, "Not unique table/alias: 'custom_jobs_values'" for the following SQL Command
SELECT companies., jobs., field_tickets., regions., customers., custom_jobs_values. FROM
companies, jobs, field_tickets, regions, customers, custom_jobs_values
LEFT JOIN custom_jobs_values ON jobs.jobs_id=custom_jobs_values.jobs_id
INNER JOIN regions ON companies.regions_id=regions.regions_id
INNER JOIN jobs ON companies.companies_id=jobs.companies_id
INNER JOIN field_tickets ON jobs.jobs_id=field_tickets.jobs_id
INNER JOIN customers ON jobs.customers_id=customers.customers_id and
companies.subscriptions_id=4.00
thanks!

How to do a TopN Sort based on a formula

Hi all,
My report has two groups, Store and Department. In the details section are multiple jobs per store with costs. These are subtotalled by Store and Department. I want to compare total spend for each store with the store budget and produce a list of the Top 10 stores based on the percentage actual spend/budget.
My problem is I can only do a Top 10 sort on a summary field and I cannot summarise the percentage field as this is a formula which doesn't seem to allow summaries.
Any help much appreciated.
Cheers,
JD

Jan,
Here are a couple of options.
1) Do the calcuations on the database (thru either a stored proc or command object).
2) Insert a crosstab where the rows are based on the Store and the summarized field is based on the formula that outputs the percentage of the actual vs budget as a Maximum. You can then do a TopN sort on the crosstab

How to extract substring from a string based on the condition ??

Hi,
I'm having a very large string which as below
EQD+CN+SAMPLE18767+2200+++5'

FTX+AAA+++IS FAIR'
similarly FTX+AAA as above and it goes on
i tokenized each segment with delimiter as ' and able to read each segment.
Now i want to concatenate the FTX+AAA in a single segment if more than one FTX+AAA with IMMEDIATE below
The output is as follows
EQD+CN+SAMPLE18767+2200+++5'
NAD+CA+FIR:172:20'
DGS+IMD+3.2+2346+55:CEL'

FTX+AAA+++SECOND,IS FAIR'
similarly FTX+AAA should be concatenated if it has similar FTX+AAA IMMEDIATE below.
The FTX+AAA segments can come any number of times immediate below
Please help me how we can do this??? Can anyone help me with the code snippet to do this?
Thanks,

Spliting a string based on Non Printable character

Hi,
i have a requirement where i have to split a String based in non printable character " MYU(ascii: 230);
es: ""This is to test æ raaaaaaaaaaaaaaaaa æ AAA010224544 æ 7118288888 æ
æ is a not printable character and its ascci is 230..
iam getting that string from form how to split it in Java..
Any suggestions...?

One of many ways
    String initString = "This is to test æ raaaaaaaaaaaaaaaaa æ AAA010224544 æ 7118288888 æ";
    String[] tokens = initString.split(String.valueOf((char)230));
    for (String string : tokens)
      System.out.println(string.trim());
    }

Can a release strategy be based on a formula?

Hi,
A retail client i'm working on wants the release strategy PO to be based on a formula, i.e. the release strategy should have OTB check.
Is this possible?
Thanks in advance for your help

Hi,
Thanks, I didn't know what OTB means.
I do not know how this OTB is maintained in the system (is it development?) but I assume it should be stored in a data table (data tables). If it is so, I think you should be able to extract it (this data) via the ABAP code in the mentioned user exit - but this is just my opinion, it's better you ask your ABAPer to check it in a sandbox system.

Determining the actual length of a string based on pixels?

How would you determine the actual length of a string based on pixels? Reason for is because a length of a string containing all " l " chars would be a lot smaller then the length of a string containing all "H" chars based on pixel width.
thanks,
newbie

Yes, look at the FontMetrics class which has methods to do just that. To get a relevant FontMetrics object, try "x.getFontMetrics(f)" where x is a Component and f is the Font your string is represented in.

I need to sort an array of strings based on the number in each string.

Basically, I have a directory of files that all have the same name but each with a different number on the end.
example: image 1.jpg, image 2.jpg, etc.
When I use the List Directory function that returns an array of strings containing the file names in the directory, they don't come out in a 1, 2, 3, order like they appear in the directory. It sorts them character by character so that they come out like: 1, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 2, 20, 21, 22 etc.
Is there a simple way of sorting this array of strings with the file names (as above) so that they are in numerical order?

It's a while since this thread was started, but I am sure others will have use for this so here goes:
The in-built array sort function sorts the strings the same way DOS and Windows do. Microsoft has fixed this in the Explorer that comes with XP, however the rest of the OS(s) still sorts the old way.
The attached "AlphaLogical String Array Sort" VIs will sort strings arrays the same way as the new XP Explorer. There are three different implementations of the sorting, one based on the Insertion sort algorithm, a Quick Sort based on recursive calls (the most elegant way, but unfortunately LabVIEW has too much overhead when doing recursive calls so this is actually a very slow alternative) and finally the fastest; a stack based Quick Sort. There is also a test VI that will show you how the different implementations perform.
I had not used recursive calls in LV much until I made the attached quick sort and was a bit disappointed by the fact that it is so slow, but it's a good learning example...The ability to do recursive calls this way was introduced in LV7 I believe...There is an example here on the zone that shows how you can calulate a factorial by using recursive calls, however - unlike for the quick sort (normally) - recursive calls are actually not the optimal solution for that calculation.

Selecting records based on user formula

Post Author: Josh@RTA
CA Forum: Formula
I'm writing reports for a company that stores all of their dates as 8 digit numerical fields rather than a date or datetime datatype. I want to convert this field to a date type, then compare it to a parameter that stores user input as a date type.
However, due to the way that Crystal does it's passes over the data, I can't use a selection formula based off of another formula. So I'm wondering , has anyone ever used a selection formula that references another formula and how have you been able to do it? Maybe use group selection instead of record selection? Just not sure.
I'm including the formula I'm using to convert the date, as well as the selection formula so you get an Idea of what I'm doing.
//This converts the numeric 'date' field to a dateshared stringvar DateString := totext({wotrans.ROP_TRAN_DATE}, 0, '');shared datevar ConvertedDate :=If {wotrans.ROP_TRAN_DATE} < 19590101 then Date (1959, 01, 01) else Date ( Val (DateString [1 to 4]), Val (DateString [5 to 6]), Val (DateString [7 to 8]) );
//This is the select statement I'm using to compare the above formula to my parameter using record selection{@ConvertedTransDate} = {?TransDateRange}

Post Author: SKodidine
CA Forum: Formula
Replace your formula with this and then equate it to your parameter value in your selection criteria and see if it will work.
If {wotrans.ROP_TRAN_DATE} <= 19590101 then Date (1959, 01, 01)
else
date(
tonumber(totext({wotrans.ROP_TRAN_DATE},0,'','')[1 to 4]),
tonumber(totext({wotrans.ROP_TRAN_DATE},0,'','')[5 to 6]),
tonumber(totext({wotrans.ROP_TRAN_DATE},0,'','')[7 to 8]));
The process might be faster if you convert or change the data type of your parameter to numeric and then compare to the numeric date.

How to group rows based on a formula value

Hi experts,
I have a query that returns a a char row (country) and a couple of columns, "Duration of Process in days" and "Counter of nº process done", each a calculated formula KF .
What I would like is to group the results based on formula KF1 results ""Duration of Process in days".
For example: from this query result
Country -   Duration of Process in Days -   Counter of nº process done

Is this possible??
Thanks in advance for your help,
Best regards,

Hi Vikram,
my problem is that the "Duration in days" cannot be a characteristic derived in the loading process, as its value depends (is calculated) based on several user's selections done in the variable pop-up screen when executing the report.
Thanks again for your reply.

Oracle Spatial function to find nearest line string based on lat/long

Hi,
Here is my scenario. I have a table that contains geometries of type line strings (the roadway network). The line geomteries are of type Ohio state plane south (SRID 41104).
I have a requirement - given a lat/long, find the line string that snaps to that lat/long or the nearest set of line strings within a distance of 0.02 miles.
This is a typical example of trying to identify a crash location on our roadway network. The crashes being reported to us in lat/long thru the GPS system.
How can i acheive this through any spatial functions?
Thanks for the help in advance.
thanx,
L.

Hi L,
That is not the way I would do it. I would convert my road segments to LRS data, then you can do all queries on the same data.
Or, if you do not want to modify your original data, create a copy of your road segments with the same ID's and convert the copy into LRS data. If you keep the ID's identical, you can easily use geometry from one and LRS data from the other - as long as you are sure the ID is the same.
Which will make the workflow a bit easier:
1. Use SDO_NN to get the closest segments
2. Use SDO_LRS.PROJECT_PT to get the projected point
3. Use SDO_LRS.GET_MEASURE to get the measure
And most of these you can incorporate into one single query. Now I am writing this of the top of my head (It's been a while since I played with LRS). so this has not been tested, but something like this should work (but could probably be greatly improved - it's getting late for me :-) ):
SELECT
SDO_LRS.FIND_MEASURE --//find_measure needs an LRS segment and a point
    SELECT            --//here we select the LRS segment
      r.geometry
    FROM
      roadsegments r
    WHERE SDO_NN(r.geometry,    --//based on the given GPS point
                 sdo_geometry(2001, 41104, sdo_point_type(lat,lon,NULL), NULL, NULL),
                 'sdo_num_res=2 distance=0.02 unit=mile') = 'TRUE'
SDO_LRS.PROJECT_PT --//We project the point on the LRS segment
      SELECT         --//here we select the LRS segment (again, which could probably be improved!!)
        r.geometry
      FROM
        roadsegments r
      WHERE SDO_NN(r.geometry,
                   sdo_geometry(2001, 41104, sdo_point_type(lat,lon,NULL), NULL, NULL),
                   'sdo_num_res=2 distance=0.02 unit=mile') = 'TRUE'
    sdo_geometry(2001, 41104, sdo_point_type(lat,lon,NULL), NULL, NULL) --//The GPS point again
AS milemarker from dual;So it is not as complicated as you think, it can easily be done with just one query (SQL can do a lot more than you think ;-) ).
Good luck,
Stefan

Parse string based on pattern

I'm trying to make a small prog that extracts a song's artist from its filename based on a specified pattern.
Something like this:
public String getArtist(String filename, string pattern) {
String artist = getArtist("The artist - the title.mp3", "artist - title");
artist = getArtist("01 - Another title - Another artist.mp3", "track - title - artist");Any good ideas on how to implement getArtist would be appreciated... :)

heres my idea of how to solve it...
this solution is not complete, but you may perfect it any way you like... it's just a quick and dirty hack ;)
import java.util.regex.*;
public class ArtistProblem {
public static void main(String[] args) {
if (args.length == 2) {
   System.out.println(getArtist(args[0], args[1]));
} else {
   System.out.println(getArtist("The artist - the title.mp3", "artist - title"));
   System.out.println(getArtist("01 - Another title - Another artist.mp3", "track - title - artist"));
public static String getArtist(String filename, String pattern) {
// change track to regex that matces any spaces nad word characters
pattern = pattern.replaceAll("track", "[\\\\w ]*");
// change title to regex that matces any spaces nad word characters
pattern = pattern.replaceAll("title", "[\\\\w ]*");
// remove extention from the end of filename
filename = filename.replaceAll("\\.mp3$", "");
// change artist to regex that groups matched pattern
pattern = pattern.replaceAll("artist", "([\\\\w ]*)");
Pattern patt = Pattern.compile(pattern);
Matcher matcher = patt.matcher(filename);
if (matcher.find()) {
   return matcher.group(1);
} else {
   // no match was found, so we return empty string
   return "";
}try running it so:
java ArtistProblem "the artist - the track - the title.mp3" "artist - track - title"
and you'll get:
the artist
i hope that gives you a jumpstart to some direction.

Conditional formating based on excel formula

Hi experts!
I have a problem with BPC formatting. Under my EVDRE expansion, I inserted a column to validate some data before sending it. The value of this formula can be TRUE or FALSE and it validates each row of the expansion.
Now, if the value is false, the row or at least some fields of it must turn red so the user knows were are the mistakes.
I have defined under the format range an entry for the heading to evaluate in rows and in format I create the next conditional formatting:: =$I38 = FALSE ---> background red.
When I push the refresh button, the format applies to al heading under the expansion, but the conditional format formula changes to =$I1064034 = FALSE
If I lock the row number, it won't iterate for each row and the format will be based just on one cell instead of one cell per row.
¿Any ideas? ¿Other ways to achieve this? I've also tried to format the cell inside the expand and eliminate the entry on the format range but it doesn't expand to the rest of the cells...
Thanks in advance

Hi Nilanjan!
Thanks for the answer, the individual conditional formatting is working fine!
The reason why it wasn't working the first time was because it's incompatible to do individual conditional formatting with conditional formatting on format range.
I gues I'll have to do all the formatting on individual cells...
Thanks agains!

How to split string based on either space or tab delimitation?

I'm trying to split a string into 4 fields. The strings sometimes have space delimitation and sometimes have tab delimitation. Is there any way to do this in a SELECT, or do I need a couple staging tables, or what?
I'm trying to work with this.
Select PARSENAME(replace(replace(replace(replace([Column 0],' ','<>'),'><',''),'char(9)',' '),' ','.'),4) Date,
PARSENAME(replace(replace(replace(replace([Column 0],' ','<>'),'><',''),'char(9)',' '),' ','.'),3) ID,
PARSENAME(replace(replace(replace(replace([Column 0],' ','<>'),'><',''),'char(9)',' '),' ','.'),2) Rank1,
PARSENAME(replace(replace(replace(replace([Column 0],' ','<>'),'><',''),'char(9)',' '),' ','.'),1) Rank2
Knowledge is the only thing that I can give you, and still retain, and we are both better off for it.

This is similar thread that someone posted a week ago
Split delimited string into separate columns
based on space
My solution was, using a user defined function to split the text:
Use Master
Go
CREATE FUNCTION dbo.udf_SplitString(@InputVal VARCHAR(200), @Delimiter CHAR(1))
RETURNS @Items TABLE (RowNo TINYINT, ITEM VARCHAR(100))
As
BEGIN
DECLARE @FieldLen TINYINT = 0, @FieldEnum TINYINT = 0, @TempItem VARCHAR(100) = '', @ItemLoop TINYINT = 1
SET @FieldLen = LEN(@InputVal)
WHILE @FieldEnum <= @FieldLen
BEGIN
IF (SUBSTRING(@InputVal, @FieldEnum + 1, 1) = @Delimiter OR @FieldEnum = @FieldLen) AND @TempItem <> ''
BEGIN
INSERT @Items (RowNo, Item)
VALUES (@ItemLoop, LTRIM(RTRIM(@TempItem)))
SET @TempItem = ''
SET @ItemLoop += 1
END
ELSE
BEGIN
IF SUBSTRING(@InputVal, @FieldEnum + 1, 1) <> @Delimiter
BEGIN
SET @TempItem = @TempItem + SUBSTRING(@InputVal, @FieldEnum + 1, 1)
END
END
SET @FieldEnum += 1
END
RETURN
END
Next, use the splited data to group based on requirements
DECLARE @AllData TABLE
[Column 0] VARCHAR(50)
INSERT INTO @AllData
VALUES('20150101 04559690 45 33')

INSERT INTO @AllData
VALUES('20150101 554567450 40 51')
;WITH CTE
AS
SELECT
,Row_Number() OVER(PARTITION BY MainQry.[Column 0] ORDER BY MainQry.[Column 0]) As RowNo
FROM
@AllData As mainQry
CROSS APPLY (SELECT Item FROM Master.dbo.udf_SplitString(REPLACE(MainQry.[Column 0], CHAR(9), ' '), ' ')) As SubQry
SELECT
[Column 0]
,MAX(CASE WHEN RowNo = 1 THEN Item ELSE '' END) AS [DATE]
