Comparing 2 comma separated value strings
Hi
I've the following requirement where i need to comapre 2 strings having comma separated values.
declare
v_Str1 varchar2(100) ;
v_str2 varchar2(100);
begin
v_str1 := '123,234,456' ;
v_str2 := '123,234';
/* *I need to write a logic to compare the above 2 strings
Could you please give me hint to achieve this* */Thanks

Try this
declare
v_Str1 varchar2(100) ;
v_str2 varchar2(100);
begin
v_str1 := '123,234,456,4364' ;
v_str2 := '123,234';
For cur_rec in (
select REGEXP_SUBSTR (v_str1, '[^,]+', 1, level) output

select REGEXP_SUBSTR (v_str2, '[^,]+', 1, level) output
from t
connect by level <= regexp_count(v_str2,',')+1) loop
DBMS_OUTPUT.PUT_LINE(cur_rec.output);

Comma Separated Value Taking too Much Time to Execute
Hi,
select ES_DIAGNOSIS_CODE DC from ecg_study WHERE PS_PROTOCOL_ID LIKE 'H6L-MC-LFAN'
The above query returns comma separated value from the above query.
I am using the query below to split the comma separated value but the below query is taking lot of time to return the data.
SELECT
select DC from (
with t as ( select ES_DIAGNOSIS_CODE DC from ecg_study WHERE PS_PROTOCOL_ID LIKE 'H6L-MC-LFAN' )
select REGEXP_SUBSTR (DC, '[^,]+', 1, level) DC from t
connect by level <= length(regexp_replace(DC,'[^,]*'))+1 )
Please suggest me is there any alternative way to do this comma separated value.
Thanks

Hi BluShadow,
I know that this function is fast with varchar2 strings from several years of using it. With CLOBs one may need something faster, but the OP didn't menion CLOBs.
Best regards,
NikolayJust because you perceive it to be fast doesn't mean it's faster than doing it in SQL alone.
For starters you are context switching from the SQL engine to PL/SQL to call it.
Then in your code you are doing this...
select substr(v_str,v_last_break+1, decode(v_nxt_break,0,v_length, v_nxt_break-v_last_break-1)) into v_result from dual;which is context switching back from the PL/SQL engine to the SQL engine for each entry in the string.
Why people do that I don't know... when PL/SQL alone could do it without a context switch e.g.
v_result := substr(v_str,v_last_break+1, case when v_nxt_break = 0 then v_length else v_nxt_break-v_last_break-1 end);So, if you still think it's faster than pure SQL (which is what the OP is using), please go ahead and prove it to us. -
How to seach for a particular text in comma separated values
Hi,
I have one table for eg. TB_Fruits.
In that i have one column FruitsName(Varchar)
In that column i am storing string in comma separated values.
Select FruitsName from tb_fruits;
Result: orange,banana,apple
Now the issue is suppose if i try to insert any of these fruits name again then it should not allow me to insert.
Suppose now if i try to insert ('grapes,banana')
or
('apple,grapes')
the orange,banana,apple can be in any position.
How to check if any of these names already exist or not in the column fruitsname?
I cannot use like or INstr function here. because the position is not fixed not even string.
Appreciate any help.After doing search.
Got to know <= 3 length in word is in stoplist.
That's why the value ALL it was not searching in index.
After modifying the index this problem is solved.
CREATE INDEX
Fruitsname_idx ON tb_fruits (FruitsName)
indextype is ctxsys.context
PARAMETERS('SYNC ( ON COMMIT)
stoplist ctxsys.empty_stoplist');
But now the issue is suppose i have value with space..
i inserted one more row with value 'FRUITS YELLOW'
So in the index it is storing two rows....one is for FRUITS and second is for YELLOW.
select * from tb_fruits t where contains(t.FruitsName,'FRUITS')>0
I will get record..but actually there should be no record.
And it should allow me to insert. So i can insert the value FRUITS in more row.
Any help on how to store the value with space in one row in index?? -
Here is my dilemma. I am an archivist at an arts organization and we are in the process of digitizing many of our materials to post them on the web and make them available to internet users. One of the principle components of our collection is a large trove of photographs. We have been in the process of digitizing these images and embedding metadata (in the Caption/Description, Author/Photographer and Copyright fields) via PhotoShops File Info command.
Now I am at a crossroads. We need to extract this metadata and transfer it into a comma separated value form, like an Excel spreadsheet or a FileMakerPro database. I have been told that it is not possible to do this through PhotoShop, that I must run a script through Acrobat or Bridge. I have no clue how to do this. I have been directed to a couple of links.
First I was directed to this (now dead) link: http://www.barredrocksoftware.com/products.html
The BSExportMetadata script allegedly exports the metadata from files selected in Adobe's Bridge into a comma separated value (CSV) file suitable for import into Excel, Access and most database programs. It installs as a Bridge menu item making it simple to use. The the Export Metadata script provides you with an easy to use wizard allowing you to select associated information about a set of images that you can then export. This script requires Creative Suite 2 (CS2). This script sounds like it does exactly what I want to do, but unfortunately, it no longer exists.
Then I found this:
Arnold Dubin, "Script to Export and Import Keywords and Metadata" #13, 8 Aug 2005 7:23 am
I tried this procedure, but nothing seemed to happen. I also tried to copy the script into the JAVASCRIPT action option in Acrobat, but I received a message that the script had an error. It also seems to me that this script does not set up a dumping point, that is, a file into which this information will be exported to.
I am a novice, not a code writer or a programmer/developer. I need a step-by-step explanation of how to implement this filtering of information. We have about 2000 jpeg and tiff files, so I would rather not go through each file and copy and paste this information elsewhere. I need to find out how to create a batch process that will do this procedure for me. Can anyone help?Hello -
Is anyone aware of a tool that will do the above that is available for mac? Everything I've found so far seems to be PC only.

Enable comma separated values (CSV) output
I am trying to figure out how to (Enable comma separated values (CSV) output ) for a report. Do you have an example or info on how to do that?

The selected file does not appear to be a valid comma separated values (csv) file or a valid tab delimited file. Choose a different file.
I guess your question is, "what's wrong with the file?"
You're going to have to figure that out yourself, as we cannot see the file.
Importing into Address book requires either a tab-delimited or a comma-delimited file. You can export out of most spreadsheets into a csv file. However, you need to make sure you clean up the file first. If you have a field that has commas in the field, they will create new fields at the comma. So, some lines will have more fields than the others, causing issues like the error you saw. -

Comma Separated Values files ?!!
Is there special classes for dealing with CSV (comma separated values) to use a text file just like a database ??
thanks in advancesorry, it just sounds like a strange thing to do. Normally, you would not use CSV for persistent data storage with a High Level Language. In your design, if you wanted to refer to a particular record, you get into all sorts of problems. You could keep a note of where each record is, like what line number its on, but then you would need some way of modifying this note when you add records. Also, you would have to be sure that no-one is accessing the file outside of the program as then things will not be where the program expects them to be. You could refer to each record using some identifier, but then if you are going to start using all of this, then you may as well go the database route. If you are new to java, it will probably help you learn. I just don't envisage you ever having to use the type of design you are talking of in practice. The closest thing that you ever might use it for is if you had a plain text configuration or parameter file for a program.

Custom Document for Comma Separated Values in a JTextField
Hi,
I tried to create a custom structured Document implementation for comma separated values (on one line) in a JTextField:
I want to have one LeafElement for each value (to store as an attribute the Object associated with this value). So, if I plug a DocumentListener to the JTextField, I can easily see which value(s) have been added/removed (see ElementChange).
I used the PlainDocument implementation as a starting point and replaced the logic related to the '\n' character by the ',' (see #insertUpdate).
Then I realized that the View must be customized too. So I created a View with a custom #paint method to draw each LeafElement on the same line.
But, now, I try to fix the ElementChange returned by the #insertUpdate and #removeUpdate methods.
Indeed, I played with a JTextArea with two lines "Bart\nisa" and plugged a debugging DocumentListener.
And the event I get when I type 'L' before "isa" is really strange:
- Two elements removed,
- Two elements added.
In the PlainDocument#insertUpdate, the code updates the 'offset' but I don't understand the logic behind.
Could you explain me why I got this result?
Could you give me an hint?
Best Regards,
El Barto.When you say the offset gets updated, I assume you're talking about this bit:
int offset = chng.getOffset();
int length = chng.getLength();
if (offset > 0) {
offset -= 1;
length += 1;
} The result is that, if a character is added at the very beginning or end of a line, the edit gets treated as a multi-line edit, which means the LeafElements on either side of the edit get removed and reconstructed. I discovered this behavior a few years ago, and I never have figured out what purpose it serves. I think you'll just have to try overriding the method to eliminate that behavior, and see what happens. -

Query on column with comma separated values
I have a proposed table with unnormalized data like the following:
ID COLA COLB REFLIST
21 xxx zzz 24,25,78,412
22 xxx xxx 21
24 yyy xxx 912,22
25 zzz fff 433,555,22
.. ... ... ...There are 200 million rows. There is maximum of about 10 IDs in the REFLIST, though typically two or three. How could I efficiently query this data on the REFLIST column? e.g. something like:
SELECT id FROM mytable WHERE :myval in reflistLogically there is a many to many relationship between rows in this table. The REFLIST column contains pointers to ID values elsewhere in the table. The data could be normalized so that the relationship keys are in a separate table (in fact this is the current solution that we want to change).
ID REF
21 24
21 25
21 78
21 412
22 21
24 912
... ...The comma separated list seems instinctively like a bad idea, however there are various reasons for proposing it. The main reason is because the source for this data has it structured like the REFLIST example. It is an OLTP-like system rather than a data warehouse. The source code (and edit performance) would benefit greatly from not having to maintain the relationship table as the data changes.
Going back to querying the REFLIST column, the problem seems to be building an approriate index for the data. The ideas proposed so far are:
<li>Make a materialized view that presents the relationships as normalized (e.g. as in the example with ID, REF columns above), then index the plain column - the various methods of writing the view SQL have been widely posted.
<li>Use a Oracle Text Index (not something I have ever had call to use before).
Any other ideas? Its Oracle 10.2, though 11g could be possible.
Thanks

Hi,
I have one existing view(with around 15 fields), in which I have to add few more fields from table called PI.
Now these fields have values like (55C4444F-D83B-4F96-A011-367A3755BA6C , F52388E2-485B-49DF-8534-FDF46D23F59E , 722432E1-F063-4CBD-B83D-1B97836E82953) 3 values comma separated.(Sometimes only one value and sometimes 4 or 5 or 7-8 depend on user has entered
on web page)
Also I have another table called PHA and this tables has 2 fields Values and Name so I have to map this two tables based on VALUES fields and get Name from this PHA table and show in view and that also Comma separated.
So basically I have to Parse the PI table's Values field 1st, map it with PHA table to get Name and then Make it comma separated in that existing view.
To make fields comma separate I used below query,
(SELECT DISTINCT SUBSTRING
SELECT ','+ PI.[Name] AS [text()]
FROM [DB].[dbo].[Table] PHA1
Inner Join [DB].[dbo].[Table] PI
ON PHA.[Value] = PI.[VALUE]
WHERE PHA1.PId =PHA2.PId and PHA1.CId = PHA2.CId
ORDER BY PHA1.PId
For XML PATH ('')
), 2, 1000)
FROM [DB].[dbo].[Table] PHA2
Inner Join [cSharpSite_profiles].[dbo].[PetAllergies] PA
Inner Join [DB].[dbo].[Table] PI
ON PHA.[Value] = PI.[VALUE]
) [Name]
VickyWait, this sounds wrong. You have a view where you group values into a comma-separated list. While that surely will make some purists cringe, I can see that it makes sense from a presentation perspective.
But if you want to use these concatenated values as atomic values again, you should go back to the base tables and them from there. Building views on views may sometimes be a good idea, but if you are too keen on reuse you can cause a performance disaster.
So do it right from the beginning.
