Character comparison.

Hi Friends,
We have a scenario in which a database table field is of type CHAR10.
Selection screen parameter is as well defined using the same field.
Actually this represents a number but is defined as character.
Now, due to character comparison we get false results when user enters a number on that selection screen.
For ex: 133.33 is evaluated greater then 1000 and the like. This is because of character comparison.
Could someone help me how can i get correct result here?
Is there some way that i dont have to change the field type in DDIC to number, and still i can get number comparison instead of character comparison?
Thanks,
Rohit.

Hi,
The character comparison indeed gives the wrong result.
check this code:
data : x1 type char10, x2 type char10.
x1 = '133.35'.
x2 = '1000'.
if ( x2 > x1 ).
   write ' successful'.
   write x1.
endif.
if ( x1 > x2 ).
   write 'unsuccessful'.
endif.
Also it wont be possible to assing char to num as you have mentioned, because comparison is done with database table field, which is character and not a number!
Thanks,
Rohit.

Most of the awt drawing methods are the same; you just need to provide a panel that calls them in its paint() method.
You also need to add text fields for any inputs, and buttons or a combo box for choosing the skill level.
You need to store high scores on the server as there is no way for an applet to access a local file.
The code int highscore1 = file1.read ();
if (highscore1 == 48)
...would better read in a string then use Integer.parseInt() rather than all those character comparisons, or one of the Character.digit() conversions.
The code that is many versions of if (score == 0)
c.println ("Wow... That was horrible: " + score + " out of 10!");
...can either be replaced with switch/case or an array of strings.
You'd be better off reducing all the code you don't need before you convert it to an applet, just so there's only half the amount to convert.

ABAP/4 Keywords for all SAP R/3 Versions

Hello Experts,
      Is there any DB Table available in Data Dictionary where all these ABAP/4 Keywords available; if yes do please let me know if not available then do please provide me with all ABAP/4 Keywords of all versions of SAP R/3 if possible
points will be awarded if helpful.
Thanks in Advance

Hello Arif,
There no particular table to check all the key words in ABAP.
To check system fields Go for
Se11-- SYST.
TO get the key words go to ABAPDOCU- type ur required key word in the search given in the last section.
The best option would be to debug ABAPDOCU, when you do a click on Keywords
Or Check the Pooled table : TSE05
As you must be knowing ABAPDOCU is in SABAPDOCU Package.....!!
There are a number of tables used; like ABTREE,etc !
Explore and find whether you can get some clue!

JVM Crash on Unix (Solaris)

Hi,
I have an application which works fine on Windows environment. If the ear prepared on Windows is deployed on Unix it works fine. But when the application is build in Unix, the application gets deployed but when accessing the application it crashes.
I have pasted the crash details below

I think I have localised the crash to a section of the code where there is character comparison done. If I comment out this section, it works fine. I ahve pasted below the section:
else if (getChar() == '\'' && getOffset() < getBuffer().length())
{ // Start of a Literal - so just copy until the end of the literal
do
sb.append(getChar());
setChar(getNextChar());
while (getChar() != '\'' && getOffset() < getBuffer().length());
sb.append(getChar()); // Append the final single quote
setChar(getNextChar());
After substituting " ' "for it integer value, I started getting a JVM crash with a different error id.; pasted it below

Could you please help me to find out the cause? Also how do you make sense of the details(which I have pasted above) in the logs written at time of crash. Is there anyway to look at the core files other than dbx or gdb?
Thanks,
Ragesh

i wrote a simple statement :
select * from tb where mdate > sysdate;
it takes long time to return resultset.
when i use to_char() function,
select * from tb where to_char(mdate,'yyyy-mm-dd') >
to_char(sysdate,'yyyy-mm-dd');
it runs faster.
who can tell me why?
thanks.

Are you running each statement multiple times and averaging the results? If you run the date comparison once, then run the character comparison, it's likely that the data you want is already cached, so the secod statement may well return more quickly. If you average multiple runs, you can avoid this.

File Merging --- Need Help

Greetings,
I am pretty new at this program, and I am trying to understand how to do my homework assignment. So I do not need the full code, just some help on how to get started.
I am trying to write a program that merges all files together whose names match a certain pattern, and writes the result to an output file. The input-file pattern will consist of a combination of "normal" filename characters and question marks (?). A question mark in the input-file pattern denotes a single-character "wild card". Thus, the pattern ab?c?.txt would denote all file names that consist of 9 characters such that:
the first two characters are ab
the fourth character is c
the last four characters are .txt
For example, this would include filenames such as abxc7.txt and abqcc.txt.
So if there are files in a folder, for example, called abc.txt, adc.txt, cat.txt, and the contents of each has two similar lines of "This is File ZZZ" Where ZZZ represents the name of the file. Then running the program with the pattern a??.txt and the output file finished.txt will result in the file finished.txt having the contents
This is file abc.txt.
This is file abc.txt.
This is file abd.txt.
This is file abd.txt.
I don't really know where to begin here. Could you help me out? Thanks

Check out the API docs for java.io.File. It has methods to list all the files in a particular directory.
For the name matching, you can create a class that implements FileFilter or FileNameFilter that you then pass to these methods.
The filter's accept method would test the file name against your criteria.
(You wouldn't have to use the filter. You could just iterate over the files and compare each one yourself.)
To do the actual comparison, you could use the String.matches() method or you could just do the character by character comparison yourself.
If you google for java io tutorial you should find something that will help you with the File class, and java regex tutorial for String.match()
Break the problem into small pieces, and get each one working before moving onto the next.
First write a method that takes in a pattern "a?bc?.txt" and a String (that represents a filename) and returns true or false depending on whether it mathes.
Then write a method that takes the patten and an array or List of Strings or Files and uses the first method to return an array or List of Strings or Files that represents the subset of the original list that matched.
Post again if you have specific questions about specific parts that you don't understand or cant' get to work.

Download csv file with strange file name.

hi, guys:
We installed Oracle APEX 4.2, and APEX listener 2.0 and Oracle 11g standard edition for our application. But sometimes when user tried to download csv file from an interactive report, the file name was a very strange one, sometimes even no .csv extension. could anyone give me a hint to find documentation about it?
Thanks.

a little more information about it:
I found the file name is "&P16_DIP_START_DATE NOA", which we expect to generate a file named as " some date NOA.csv", but APEX does not recognize the value of variable. For example, if teh value of P16_DIP_START_DATE is 11/15/2012, we expect the file name as "11/15/2012 NOA.csv", but APEX will give us very strange file name replaceing every "/" with / I appreciate anyone who could help me on this issue. But We did not encounter this [roblem on APEX 4.1, OC4J and Oracle 11g R2 enterprise.
Thanks.
I just used to_char to output date without "/" and soleved it. The other way is to set application property-->security-->browser security with basic level. This only applies to APEX 4.2. I am lucky for that I am using Apex 4.2.

I can has editing?Suspect you are trying to explain that "/"s are being rendered as <tt>&#x2F</tt>? If you want to include character entities in forum posts then you have to type the ampersand ("&") as an entity itself, thus: <tt>&amp;#x2F</tt>.Windows or *NIX filenames can't contain "/"s anyway, so you can't use them regardless of how APEX is rendering them. Using a <tt>YYYYMMDD</tt> format is also recommended as it follows date order when using character comparison semantics.

URGENT - ORA-01722 Causing Chaos!

A few days ago, our test server suddenly took a dislike to numeric-to-character comparisons e.g.
SELECT whatever
FROM my_table
WHERE my_char_column = 1;
This type of code is commonplace as we have a lookup table for decoding codes which, by its nature is entirely VARCHAR2 to encompass all data types that may be stored therein.
Somewhere on Google it suggested...
"Oracle will automatically convert a string to a number when a number-to-character comparison is made UNLESS there is an index on the string's column."
Indeed, an index was missing. This was restored and code like that above started to work again (as it had for years previously!).
However, today on our live server the same ORA-01722 errors suddenly started to occur (affecting most transactions). The software (Oracle Forms) has not changed and all indexes are intact. The longstanding code is similar to that above with the additional use of a TO_NUMBER function.
In SQL*Plus the following code logic works on our copy of the database as it was yesterday:
SELECT whatever
FROM my_table
WHERE TO_NUMBER(my_char_column) = 1
AND my_other_char_column = 'SOMETHING';
It doesn't work against today's database. The numerous parts of the system reporting the error are unchanged as far as the actual code is concerned.
The DBA people are confused (understandably) as they cannot recall doing anything of note to the database or the affected table.
Any suggestions would be greatly appreciated on what could have caused this behavioural cnange in Oracle.
Professor Yaffle

Many thanks - an interesting read.
Our DB is 8.1.7.4. It does all seem to point towards Oracle's optimisation - does this change its behaviour on the fly? I'll ask DBA explicitly whether CBO/RBO has been toggled (but surely they'd have mentioned that already). I know they tinkered with it a couple of years back with detrimental effect...
There are non-numeric values in my lookup table, due to its nature, but the conditions of the SQL statements have thus far suppressed the error.
I'd love to change all our code to live happily with the optimisation rules (i.e. compare like with like) but that will take time (months probably!) & all I'd like to acheive is to get the database behaving as it did yesterday.
NEWSFLASH: DBA suggests "someone analysed the table". Hmmm. Methinks the problem will soon strangely go away once affected table's optimisation method is restored to that of yesterday!
Grrr...

TextEdit Applescript help counter of certain words

I have tried to modify a script that finds and replaces text. My goal is to count the instances the script finds a word, say "love", and spit out the number of instances that the word "love" appears in the document so I can use it for another subroutine. Any help is appreciated.
I have this as guideline but it seems it does not work.
tell application "TextEdit"
set myCountSign to text of document 1
set myCount to count myCountSign
repeat with this_word in myCountSign
if (this_word as string) is "love" then
set myCount to myCount + 1
end if
end repeat
myCount
end tell

The most obvious problem with your script is the line:
repeat with this_word in myCountSign
This looks at myCountSign (a block of text) and iterates through it assigning each text object to this_word.
The problem is that by default each 'text object' is each character therefore you're comparing each character in the text to the string 'love' which will never, ever match. Even if the word exists you'd be performing a character-by-character comparison.
The simplest fix is to tell AppleScript to look at the words in the text, which is done simply by:
repeat with this_word in (words of myCountSign)
(note you might also need to do this for 'set myCount to count myCountSign' since this will return the character count, not the word count)
There are other, more efficient ways (such as via text item delimiters):
tell application "TextEdit"
  set myCountSign to text of document 1
  set wordCount to (count words of myCountSign)
  set {oldtids, my text item delimiters} to {my text item delimiters, "love"}
  log set keywordCount to (count text items of myCountSign) -1
  set my text item delimiters to oldtids
  display dialog "The document has " & wordCount & " words and " & keywordCount & " occurrences of the word 'love'"
end tell
The text item delimiters approach works by breaking the text into chunks at each occurrence of the delimiter (in this case, the string 'love'). Then all you have to do is count the number of chunks (minus 1) which is a lot quicker than counting all the words, especially for large documents.

Parsing data with java is killing me

i created some data in notepad
which contains :: embedded in the data
my loop gets to the :: and does not see the ::
while
(Strpos < (line.length() ) ) {
index = Strpos +2;
colons = (line.substring(Strpos, index)) ;
System.out.println(colons);// i can see the value i'm looking at here
if (colons != "::")
displayline.append(line.substring(Strpos, Strpos + 1));
Strpos++;
the pgm always executes the displayline.append.
is this because i created the data in notepad
i'm really getting discouraged with java.

Essentiallly what you're trying to do here is compare Strings. By using the == operator (or != in your case), what you are actually comparing is the address location, which is always going to return true for you, since the address are going to be different (not equal for your code example). Try changing your if statment to the following:String colonMatch = "::"
if(!colons.equals(colonMatch)) // if you current search is not equal to a pair of colonsUsing the equals() method does a character by character comparison, which is what you are needing. I've made this mistake myself a few times, so no worries.

Problem
We have a vendor system that constructs the SQL to be sent to the database. These queries have the following generic structure for a WHERE clause condition:
CASE WHEN <condition> THEN <table>.<column> END = '<value>'We've noticed significantly different execution plans when the optimizer compares numbers instead of varchar2. The examples below demonstrate that. In our case this difference is impacting the execution plans of a larger query effectively doubling buffer gets and resulting in execution times that are 2-4 times as worse.

Centinul wrote:

Validate email address pre-Oracle 10g

I want the result to be like the following, but for Oracle 9:
SELECT email_address
FROM    mytable
WHERE   REGEXP_LIKE (email_address, '[A-Z0-9._%-]+@[A-Z0-9._%-]+\.[A-Z]{2,4}');I found a website that said the following...
In pre-Oracle10g versions of Oracle, in order to get this type of equality of characters you needed to use a combination of the NLS_UPPER and NLS_LOWER functions or use the NLS_SORT setting of GENERIC_BASELETTER. While these approaches worked they do have the flaw of having to programmatically code the NLS_UPPER or NLS_LOWER functions into every select statement. Or when using the GENERIC_BASELETTER you had a solution that was not a true linguistic solution for character comparison.
http://www.databasejournal.com/features/oracle/article.php/3494646
...but I don't exactly know how to use those commands. Could anyone lend me a helping hand?

Thank you Justin for your reply. So in the query I would call a wrapper function which I would write to go on the server that would feed the owa_pattern_match package, my string and pattern to match. In the wrapper function I would get the boolean value, and convert it to a number or varchar2 (since the database does not support boolean data types?), like 'Y' for TRUE, and that would be the return value of the wrapper function. Do I have this right?
Why can't I just directly reference the built in package?

Is there any SQL function to compare 2 strings?

If you are looking for a character by character comparison then you would have to do something like...

Cavaj

Hi,
I have the source code which I am not sure is the latest. So I plan to take the class file, use a converter tool like cavaj and then compare the file with the source using Eclipse.
But I want to know how will the output of cavaj be.Will it give me the exact replica of the original source(which as compiled). This is important because eclipse does a character to character comparison.
Is there a better way of doing this??

I have the source code which I am not sure is the
latest. So I plan to take the class file, use a
converter tool like cavaj and then compare the file
with the source using Eclipse.As you've heard that's not possible, but you could try the other way:
Compile your source and do a byte-for-byte comparison of the resulting class file. You have to be carefull to have the same compilation environment, 'though. Different compiler versions, different flags (-g, -O) and so on can result in slight changes in your class file.
And if you are very desperate. Compile your source and then decompile both class files and do a visual diff on those two.
But the real solution is to only roll out clearly identifyable binaries where each binary can be directly mappe to a single version of your source code (for example some Version-Information in the jar files Manifest). You'd also want to tag the coresponding version in your version control system (like CVS, you do use one, don't you?).

Cannot read unicode

hi,
I want to perform a SELECT command and inside it i use a "unicode persian character" comparison like :[ SELECT * from products where Category = 'نام' ]
but sql server returns no data and just displays an empty result . i tested it with some other data which are not unicode and they worked fine . but whenever unicode characters are used , no result would be displayed . could anyone help please? tnx.

Here is the explanation for the N prefix.
BOL: "Unicode strings
Unicode strings have a format similar to character strings but are preceded by an N identifier (N stands for National Language in the SQL-92 standard).
The N prefix must be uppercase. For example, 'Michél' is a character constant while N'Michél' is a Unicode constant. Unicode constants are interpreted as Unicode data, and are not evaluated by using a code page. Unicode constants do have a collation.
This collation primarily controls comparisons and case sensitivity. Unicode constants are assigned the default collation of the current database, unless the COLLATE clause is used to specify a collation. Unicode data is stored by using 2 bytes per character
instead of 1 byte per character for character data. For more information, see
Collation and Unicode Support."
