InStr question

When i use the InStr function, it return the first finding in the string.
How can i find the last time it apper?
wodi :=abc@cdf@fre@ytr;
instr (wodi,'@')
give me the first time.
i use:
instr(wodi,1,(length(wodi)-length(replace(wodi,'@','')))
to find the last one.
can i do it in more nice way??

You can use 4 parameters for INSTR.
instr(string, search_string, -1, 1)will give you last occurance because it starts searching from end.
For an insight, see this.

Dbms_lob.instr question

Hello,
I have a field that holds CLOBs in the database. I have a textfield in which the user can enter a target string, then I hope to use dbms_lob.instr to search for the target string in CLOB. The code looks like: dbms_lob.instr(upper(I.COMMENTS),upper(nvl(:P26_SEARCH_NAME,I.COMMENTS))). If I replace the textfield value :P26_SEARCH_NAME with a string, the line works fine, but the current line returns the error
ORA-22835: Buffer too small for CLOB to CHAR or BLOB to RAW conversion (actual: 6250, maximum: 4000) Can someone offer some help with a fix?

Steven - Try v('P26_SEARCH_NAME') as a test to see if it makes any difference. If not, I can look at your test case if you put it on apex.oracle.com.

Basic instr question (unclear orcale docs/fundamentals guide)

Hi,
i'm obviously quite new to this, but do understand the instr function more generally, its just the 'position' variable that's confusing me a bit, and both the oracle documentation and the fundamentals exam guide are quite vague on it.
The INSTR(source string, search item, [start position],[nth occurrence of search
item) function returns a number that represents the position in the source string,
beginning from the given start position, where the nth occurrence of the search item
begins
ExamplesExample 7-127 Using Character Position to Search Forward to Find the Position of a Substring
The following example searches the string "Corporate Floor", beginning with the third character, for the string "or". It returns the position in "Corporate Floor" at which the second occurrence of "or" begins.
SHOW INSTR('Corporate Floor','or', 3, 2)
14
surely these two things are just untrue?
if the search began from the given start position in the example taken from oracle docs, the answer would be 12, not 14? from character 3 ('r') to the second instance of 'or' is 12 characters inclusive, isn't it?
or have i completely misunderstood?
thanks,
Nick

Hi, Nick,

... btw, why do the tags not work?What are they supposed to do?
If you want to post formatted text on this site in a fixed-width font, without compressing whitespace, then type these 6 characters:
\(small letters only, inside curly brackets) before and after each section of formatted text. This is great for query output as well as code samples.

Loop & Instr question

Dear all,
I have a string that will spool to a file from sql*plus, and the string maybe more than 255 characters, e.g.:
v_sql := 'select surname, firstname, sex, birth,
address1, address2,
address3, ..., .... from employee;'
dbms_output.put_line(v_sql);
Now, I want to chop the string in several lines when 'meet' the comma ',' , the output I want become to, e.g.:
dbms_output.put_line('select surname,');
dbms_output.put_line('firstname,');
dbms_output.put_line('sex,');
dbms_output.put_line('... from employee;');
So, I use the loop and instr in a procedure:
procedure xxx (p_sql in varchar2) is
v_len number := length(p_sql);
v_comma number := 0;
v_next_comma number := 0;
v_string varchar2(1000);
begin
for v_cnt in 1..v_len loop
if v_comma = 0 then
v_comma := instr(p_sql, ',');
v_string := substr(p_sql, 1, v_comma-1);
dbms_output.put_line(v_string);
else
v_comma := instr(p_sql, ',');
v_next_comma := instr(substr(p_sql, v_comma+1, v_len-v_comma), ',');
v_string := substr(p_sql, v_comma+1, v_next_comma-1);
dbms_output.put_line(v_string);
end if;
if v_comma > 0 and v_next_comma = 0 then
v_cnt := v_comma +1; <--- v_cnt will not change
elsif v_next_comma > 0 then
v_cnt := v_next_comma +1;
end if;
end loop;
end xxx;
From the above coding, however, I found a problem that v_cnt will not skip to the 'comma' position. And I feel that it is not efficient if the length of the string is very long...
So, is there another way to do? Please help. Thank you!

yes, it would see that you aren't running 10r2. here is the code you need
http://www.oraclecommunity.net/group/sqlplus/forum/topic/show?id=1988559%3ATopic%3A9386
the file - vsql.sql - is attached at the end. instead of using a cursor loop (curr_sql in my code) to get a statement, you'll just use your sql statement already in a variable. it's a simple procedure - breaks on certain keywords, or delimiters (like commas) before the linessize (132) is reached, and dbms_outputs the text.
changing the end of script to use a static sql statement:
begin
my_stmt := 'MERGE /*+ dynamic_sampling(ST 4) dynamic_sampling_est_cdn(ST) */ INTO STATS_TARG'||
'ET$ ST USING (SELECT STALENESS, OSIZE, OBJ#, TYPE#, CASE WHEN STALENESS > .5 THE'||

sql_frmt ( my_stmt, save_line, prefix );
         if (save_line is not null) then
            dbms_output.put_line( prefix || save_line );
            save_line := null;

I have many questions about this program, but let me ask this one first:
In the TrueFalseQeustion class, why are there so many constructors? What is the purpose of setting some of the variables to default values?
Thank you very much!!!

} I don't understand why the assignment wants me to build a method in the MultpleChoiceQuestion class to store the potential answer choices, I can make the program display the potential answer choices by including them in the questionText as following in the QuizDriver class
Question x;
x = new MultipleChoiceQuestion("What is the color of the car\na.Red\nb.Green", "a. Red", 3);
t.addQuestion(x); I don't know how to allow the client to construct the list of answer choices one at a time(add one potential answer choice by calling the addAsnwerChoices() method once)
Here are a few original sentences of my assignment which describe what I should do with the MultipleChoiceQuestion class
Using TrueFalseQuestion as a model, develop a new MultipleChoiceQuestion class that can be used to represent a problem where the user must select one of several answer choices (e.g., "Select answer (a), (b), (c), or (d)."). This new question type should have all of the same externally-visible functionality as TrueFalseQuestion, except that it must:
maintain a list of potential answer choices
provide a method that allows the client to construct the list of answer choices one at a time (i.e., the client should be able to call an addAnswerChoice() method to pass a new answer option to the MultipleChoiceQuestion.)
display (as part of the question text) the list of answer choices with appropriate letters ("abcd" instead of "0123") I don't understand what these sentences mean.
1. "Maintain a list of potential answer choices"-- this reminds me of the getPossibleAnswerChoice() method in the TrueFalseQuestion class
public String[] getPossibleAnswerChoice ()
        String[] possibleAnswerChoice = {"true", "false"};
        return possibleAnswerChoice;
    }I wonder that if the potential answer choices I have to store in the MultipleChoiceQuestion class are only letters "a", "b", "c", "d", etc, or include the answer text coming after the letters(eg. a.Red, b.Green)
2. "provide a method that allows the client to construct the list of answer choices one at a time". How do I achieve the functionality "one at a time"? Do I need to pass the input of the client (a potential answer choice) to the variable of the method which stores the list of potential answers?
3. "display (as part of the question text) the list of answer choices with appropriate letters". My question here is that: When the client type in one possible answer, should I append it to the variable questionText? (So I use the questionText variable in the methods of the first and second steps)
Thank you very much for your nice help!

How to store the data of a file into an ArrayList?

Hi! everyone.
I want to know
if I have a File, and the data in the file are type int, type String...
And I have a ArrayList which is of type Question
How do I store the data of that file into the ArrayList
I tried to use the while loop(use the hasNextLine() to read the data line by line)
But I cannot add data which are not of type Question to the ArrayList.
Can you tell me what I should do, please?
I also wonder that
The data of the file are of many types, but when I try to read it with the nextLine(), the data all turn out to be of type String. Why?
Thank you.
Edited by: Terry001 on Apr 30, 2008 1:13 PM

No, a line in the file is just part of a question
The format of the file is like this:
*<question type code>                    :     String*
*<question point value>                    :     int*
*<question category>                         :     String*
*<question difficulty level>               :     int*
*<question text>                              :     String*
*<question correct answer>               :     String*
*<optional question-specific data>     :     String*
*<question terminator>                    :     String*
And here is an example
TF //TrueFalseQuestion
5 //points value
None //category
3 //difficulty level
The capital of the United States is Washington, D.C. //question text
True // answer
*** //quetion terminator
I created an ArrayList in the Test class:
private ArrayList<Question> questions; // Create inside constructor
    public Test (String name, String instr)
        testName = name;
        scoreEarned = 0;
        scorePossible = 0;
        instructions = instr;
        questions = new ArrayList<Question>(); //[MAX_NUMBER_OF_QUESTIONS];
    }And I tried to use the following method to store the data of the file to the ArrayList
// This method loads a set of questions from a plain text file
    public void loadQuestionsFromFile(String fileName) throws FileNotFoundException
        try
            File fileReader = new File("input.txt");
            Scanner sc = new Scanner(fileReader);
            while (sc.hasNextLine())
                // I don't know how to pass the data I got from the nextLine() method to the ArrayList because they are of different type
        catch (FileNotFoundException a)
            System.out.println(a);
    }    As all you said, I should create an Question object in the while loop
Question temp = new Question ();But I have no idea how to pass the int and String to the Question object.
Thank you

Multi-column chart issues

Hi,
I'm trying to make a 2d column chart of quiz entry results with multiple series (one per possible answer) but it's not working as intended. I have 5 series all with code like:
select null link, substr(question, 1, INSTR(question,' - ',1,1)), count(answer) from quizdata
where answer ='Strongly Disagree'
and :P13_DEP = emp_dep
and to_char(sysdate, 'YYYY') = to_char(ins_date, 'YYYY')
group by substr(question, 1, INSTR(question,' - ',1,1))Except with the answer being different (Agree, Strongly Agree~). However, when I load the page it only shows the results of the first series (Strongly Disagree, or if I delete that then Disagree)...anyone see what I'm doing wrong?
x-axis = question
y-axis = count (number of people to select that option this year)
There should be 5 columns per question.
Mike

For anyone who has a similar issue with multiple series being displayed the reason for my error was that I didn't specify a name for the value...since all of them were count(c) they clashed; making it count(c) "Disagree" etc made it display as intended.
Mike

Text Style question re INSTR Global text source - Logic Pro X

I write arrangments for an 18 piece big band. The line up is 5 saxes, 4 trumpets, 4 trombones, piano, bass, drums, male vocalist & female vocalist.
I only have one GM sound module (Kentron SD2). I use a Midisport 2x4 Midi Interface between the Mac Mini and the Sound Module.
The set up in Logic Pro X is that in the midi envronmemnt I have 1 multi instrument with the complete band linked up to that
The set up is as follows:
Channel 1 1st and 2nd Altos
Channel 2 1st and 2nd Tenors
Channel 3 Baritone
Channel 4 1st and 2nd Trumpets
Channel 5 3rd and 4th Trumpets
Channel 6 1st and 2nd Trombones
Channel 7 3rd and 4th Trombones
Channel 8 Piano
Channel 9 Bass
Channel 10 Drums
Channel 11 Male Vocal
Channel 12 Female Vocal
All the above instrments are on individual tracks even where they share a midi channel- these parts are printed out for use by the band
Channel 13-16 are spare channels that I use during the development of the arrangement - the track contents for these are not printed out
Here is the problem. When I print out the parts for the various insturments and use the INSTR global text to identify the specific instrument on the part header, what is displayed is the patch identity for the various instruments as indicateid in the Library. Logic is not reading the track name for this.
It follows that 1st and 2nd Altos will show on the part header Alto Sax - similarly for the other wind instruments sharing a midi channel.
I am a recent convert from Logic Audio for Windows v 5.5.1 where I used the same set up. In that case Logic read the track information and therefore the instrument identification was correctly displayed on the printed parts.
Any ideas how I can overcome this problem without having to go into each part and manually change the instrument description.
thanks

Hi everyone, Sorry for my earlier long post, I just found the answer. All I needed to do is select REGION instead of INSTR

Substr/Instr/analytics question

I have a table like this on 9i (soon to be 10g)
CREATE TABLE BASELINE_TESTRUN
RUNID VARCHAR2(42 BYTE) NOT NULL
with data like this:
insert into BASELINE_TESTRUN values ('DEV1-XXX-01');
insert into BASELINE_TESTRUN values ('DEV1-XXX-03');
insert into BASELINE_TESTRUN values ('DEV2-XXX-01');
insert into BASELINE_TESTRUN values ('DEV2-XXX-02');
insert into BASELINE_TESTRUN values ('DEV2-XXX-03');
insert into BASELINE_TESTRUN values ('DEV2-XXX-05');
insert into BASELINE_TESTRUN values ('DEV2-XXX-06');
insert into BASELINE_TESTRUN values ('DEV2-XXX-06');
The output should be the next higher number of the last substring in runid
DEV1-XXX 04
DEV2-XXX 07
There may be missing no, and/or duplicates.
This was my Query for this - It works but seems rather clumsy. I would like to have done it in 1 SQL (avoiding the select from (select)):
select runid , max (next_runno) next_runno
from
select substr(runid,1,instr(runid,'-',1,2)-1) runid,
max(substr(runid,instr(runid,'-',1,2)+1))
over(partition by substr(runid,1,instr(runid,'-',1,2)-1)) + 1 next_runno
from baseline_testrun
where instr(runid,'-',1,2) > 0
---where runid like 'whatever%'
group by runid;
Alternate solutions would be appreciated ... and NO I did not define that table like this.
I would have preferred a sequence and a keys that was not composit (Codd/Date, pls. forgive the creators of the table)
best regards
Mette

You are grouping you data. In this case an aggregate function could be more helpful than an analytic function.
In 9i already you are be able to use the KEEP syntax for aggregates.
Look at this example
SQL> select substr(runid,1,instr(runid,'-',1,2)-1) group_run,
2 to_number(
3 max(substr(runid, instr(runid,'-',1,2)+1))
4 keep (dense_rank last order by substr(runid, instr(runid,'-',1,2)))
5 )+1 max_run
6 from BASELINE_TESTRUN
7 group by substr(runid,1,instr(runid,'-',1,2)-1);
GROUP_RUN                                     MAX_RUN
DEV1-XXX                                            4
DEV2-XXX                                            7
SQL> Dimas Version is better, since it avoids the keep syntax, that is not really needed for this special case.

NOT INSTR not working

Hi All,
I have a form page which is having multi select list. I am passing the multiselect list value from page 1 to page 2. In page 2 i want to use that value in my code to exclude it from report. But my not instr is not working. Please check my code. My last AND is for not instr.
Edited by: User_Apex on May 25, 2011 8:21 AM

Bingo...its working.... Thanks a million...i was using some other P2 instead of P3.
Well my question is still unsolved. Please check this thread of mine. It is related to my query
passing the value of multi select list from one page to another
You know when i am selecting two values from multi select list from page 1 and passing it to page 2 then only 1 value is coming in page 2. But when i am clicking on edit for page 2 and then running the page two then both selected values are displayin...i dont know where it is failing. Any suggestion.?

A CSS question I think

If you would take a look at this page http://www.gcfa.org/add_data.asp you will see that between the header and the navigation bar a white line is there. I don't won't it there, how can I get rid of it?

How to package instrument driver in the user.lib or instr.lib directory

Hey guys,
I currently am using bunch of instrument drivers in my project.
In the VI form it works fine, but I noticed that once converted to an executable,
there are errors regarding the DLL that the drivers are calling.
Apparently the driver VI check if its being called in an VI or executable based on the current directory.
I dont think this is good/correct programming to begin with... but anyways since this driver is
saved in the instr.lib directory of LabVIEW, when I call it from the executable the default path becomes
XXX.exe/1abvi3w/instr.lib/.../.../VI above.vi
I saw this post which talks about how vi's in instr.lib and user.lib will get the path 1abvi3w in an executable but never talked about how to deal with it.
so my question is can i solve this problem smoothly without copying the entire driver.lvlib into my project and
editing the VI above? i am fine with creating wrappers for driver vi's but would to like to avoid editing the driver vi's themselves.

I don't disagree, but there is a reason this code was written like that (you might note that it doesn't actually work) - before 2009, EXEs were built as flat directory, so stripping twice would bring you to the folder. Because of the addition of libraries, where different files have different names, this was no longer possible, so 2009 builds the EXE as a zipped hierarchy of folders, which is why the check for a folder succeeds even inside the EXE.
There are a couple of things you can do:
Replace the VI path with the Application Directory primitive. This is designed to function differently in an EXE. Understandably, you don't want to do that.
Check the 8.x checkbox in the advanced page of the build settings. This will make the code work correctly, but if there's LVOOP code with VIs of the same name anywhere, it will create extra folders that you need to move around with the EXE.
Add the driver to the project (just the lvproj, don't actually copy the files) and then set an explicit destination in the build for its VIs as an LLB in the data folder. This will place the driver VIs in an wLLB, which is external to the EXE and should then strip correctly. I can't say I have much experience with this, but I'm assuming it should also work with code that was originally in user.lib. This is probably the cleanest solution in terms of number of files because you only have one extra file.

Urgent - INSTR() Functions in OBIEE?

Hi All,
I just got some very good help from the DB experts on these forums about solving a problem with a table join that I had.
But now I have this SQL query and I'm trying to figure out how to implement this in OBIEE:
select *
from TABLE1,TABLE2
where instr(TABLE2.USER_ID,TABLE1.USER_ID) > 0
My question is how do I implement this instr() function on OBIEE? I checked physical and business model mapping layers in the repository and it does not allow me to configure this type of join. Is it possible to configure this type of join function to be invoked automatically everytime a user runs a certain query in OBIEE (as if it was a natural join)?
Any help would be greatly appreciated.
Alan

DBMS_LOB.INSTR - Searching for a pattern

Hi
I have a program supporting several databases. F.ex SQL2000 and Oracle 8/9.
The field in question, text, might contain a lot of characters. In Oracle, it's a CLOB,
on SQL2000 it's a varchar. It is not possible for me to alter the database-structure in
any ways at this moment. The database-schema is locked.
My question is pretty simple, you have probably seen it before.
In SQL2000 I can use this query:
select count(*) from crm5.text where text like 'n%'.
The result returned = 8.
The same on Oracle will be somewhat like:
select count(*) from crm5.text where dbms_lob.instr( text, 'n') > 0
The result returned = 29.
The databases has the same data.
It seems to me that the dbms_lob.instr
does a (case-sensitive) query like this:
select count(*) from crm5.text where text like '%n%
Is this the right assumption? How can I get the correct number
of rows and do the search case-insensitive at the same time not
killing the performance of the database? We use a pretty smart
little thing on "normal" LIKE. But how can we do this with the
CLOB?
Regards,
Ivar

Found the solution.
On Oracle 9, use LIKE as you want.
On Oracle 8, use
select count(*) from crm5.text
where dbms_lob.instr( text, 'N') = 1
or dbms_lob.instr( text, 'n') = 1.

Question marks in instrumentation library

I'm running labview 5.1. All of a sudden, when I pop up my functions palette, the instrument drivers show up as a question mark. I've got all the files in the proper directory: \labview\instr.lib
I know it's a dumb questions, but I can't figure how to set it back.

Be sure the palette set you have selected is the default one, and that dir.mnu is in your instr.llb directory, if not, you can create a new palette set and link the new menu to that directory, once you do that, the icons should appear again...
Good luck
