Decode a blob field with a C script in a select query

HI
I have a coded field in a table which has been populated using 3rd party software. I need to decode this field so that i could rub a few reports. I have a C script that can decode this field but do not know how to call it up from a select statement.
Is there any way of decoding this by calling up the C script in a select query.
Thanks.

can you duplicate this code into a PL/SQL function?
Or else, you might try configuring your external procedures setup and call this routine (if it was available as a shared library or a DLL).

Import Text Data to text fields with folder level script

I am using Adobe 9 professional and have a folder level javascript to import text into existing fields of a pdf.
There are multiple fields with multiple rows of data to be imported.
The folder level script is not working (but there are no errors in the console showing when run)
I have manually tested opening the text file with the following code in the console and the text file opens and populates the text fields, so the text file must be correct:
this.importTextData();
The following code is the folder level script which is not working:
function mailmergeFunction()
// Import the first row of data from "Mailmerge.txt"
this.importTextData("/h/mail merge/Jo Smith's Things/Mailmerge.txt", 0)
if (typeof cnt == "undefined") cnt = 0;
this.importTextData("/h/mail merge/Jo Smith's Things/Mailmerge.txt", cnt++ % 4)
app.trustedFunction(mailmergeFunction);
app.addToolButton({cName: "Mail merge",cExec: "mailmergeFunction()",cTooltext: "Mail Merge",cEnable: true,nPos: 14});
If anyone can please provide some assistance, it will be most appreciated thanks.

Working fine now, changed the location of the file path - could have been something to do with having an apostrophe.
function mailmergeFunction()
app.beginPriv()
// Import the first row of data from "Mailmerge.txt"
this.importTextData("/h/mail merge/Mailmerge.txt", 0)
if (typeof cnt == "undefined") cnt = 0;
this.importTextData("/h/mail merge/Mailmerge.txt", cnt++ % 4)
app.endPriv()
app.trustedFunction(mailmergeFunction);
app.addToolButton({cName: "Mail merge",cExec: "mailmergeFunction()",cTooltext: "Mail Merge",cEnable: true,nPos: 14});
Thank you for your assistance George, much appreciate your help.

Update text fields with xml data based on DDL selection of an ID number

Hi guys,
this one should be straight forward, but I cant seem to find a straight forward answer. In a nutshell:
XML file contains ID, Name, Location (so far 3 records in sample xml file)
Form contains a Dynamic Drop down list to allow selection of ID and text fields to display the associated name and location of that ID. The binding of the Drop down works fine, however I need the other fields to update to the associated name and location when different ID's are selected. I assume I'll need some sort of exit event on the drop down list to update the other fields with the Name and location of the ID selected, but I dont know enough to have a stab at it.
please, please, please help, Im starting to pull my hair out.
James.

Hi James,
This would depend on the structure of your XML but assuming you have something like;
<Data>
            <Item>
                        <Id>1</Id>
                        <Name>Name1</Name>
                        <Location>Location1</Location>
            </Item>
            <Item>
                        <Id>2</Id>
                        <Name>Name2</Name>
                        <Location>Location2</Location>
            </Item>
            <Item>
                        <Id>3</Id>
                        <Name>Name3</Name>
                        <Location>Location3</Location>
            </Item>
</Data>
Then in the change event of your dropdown (your could use the exit event but then value might not have changed so would be performing unnecessary processing) add the following code.
var itemGroup = $data.Data.resolveNode("Item.(Id.value === '"+xfa.event.change+"')");
Name.rawValue = itemGroup.Name.value;
Location.rawValue = itemGroup.Location.value;
The xfa.event.change will be the value selected, the resolveNode will return the Item with the matching Id, and then it is just a matter of assigning it to your form fields.
Hope this gets you started.
Regards
Bruce

Problem w/ image item using 9i BLOB field and InterMedia ORDImage Object

Hi,dear all,
I have a problem with image item in Form 6i. Oracle 9i is used as backend DB, and a table contains image data is created for testing:
create table image_test(
id number,
image blob
In Form 6i, there is no problem to create a block for inserting/updating the image record into the database. However, it can not be used to retrieve image (blob field), the image item remains empty after 'execute query', while the id field can be retrieved. When the same table is created in Oracle 8.1.7, and the exact same form can be used without any problem both in inserting and retrieval. It seems that the Oracle 9i does not use the same way to store BLOB column. Has anybody ever encountered this problem? How to retrieve image (BLOB) in Form 6i from Oracle 9i?
I tried to use interMedia ORDImage as the data type in Oracle 9i, that is,
create table image_test(
id number,
image ORDSYS.ORDImage
Same problem, the form can insert record with image, but when retrieving, nothing displayed. Anybody could help! Thanks in advance!

hi!
well working with oracle8i and form6i.
same problem..but i used (instead of blob or clob as datatype..) Long raw..
it can be saved as usual..i mean Commit..
and can be retrieved..using Execute_Query..its working fine..
well if anybody get any other solution..do inform..

Slow Select Query - Where clause contains Seconday index field +other flds

Hi friends,
The below query is taking about an Hour to execute in production server when there are about 6 Million records in PLAF table. I have verified the trace in ST05 and the correct secondary index (Material Matnr + Plant Plwrk) is being selected.
SELECT plnum
             matnr
             plwrk
             pedtr
             dispo
             rsnum FROM plaf
            INTO TABLE it_orders
            WHERE ( ( matnr IN r_mat1 ) OR
                             matnr IN r_mat2 AND dispo IN s_mrp1 ) AND
             pedtr IN s_date AND
             obart = '1'.
Will it be a good idea to have only MATNR (secondary index field) in the where condition of the select query and delete the internal table entries for the other where conditions ?
Edited by: Shruthi Seth on Feb 1, 2009 10:10 AM

Hello.
Creating a range r_mat = r_mat1 + r_mat2, I would do something like:
READ TABLE s_mrp1 TRANSPORTING NO FIELDS INDEX 1.
IF sy-subrc EQ 0.
SELECT plnum matnr plwrk pedtr dispo rsnum
    FROM plaf
    INTO wa_orders
   WHERE matnr IN r_mat
     AND pedtr IN s_date
     AND obart = '1'.
    IF wa_orders-matnr IN r_mat2.
      CHECK wa_orders-dispo IN s_mrp1.
    ENDIF.
    APPEND wa_orders TO it_orders.
ENDSELECT.
ELSE.
SELECT plnum matnr plwrk pedtr dispo rsnum
    FROM plaf
    INTO TABLE it_orders
   WHERE matnr IN r_mat1
     AND pedtr IN s_date
     AND obart = '1'.
ENDIF.

Strange results with Insert statement having select query

Hi all,
I am facing a strange issue with Insert statement based on a select query having multiple joins.
DB- Oracle 10g
Following is the layout of my query -
Insert into Table X
Select distinct Col1, Col2, Col3, Col4, Function(Col 5) from Table A, B
where trunc(updated_date) > = trunc(sysdate-3)
and join conditions for A, B
Union
Select Col1, Col2, Col3, Col4, Function(Col 5) from Table C, D
trunc(updated_date) > = trunc(sysdate-3)
and join conditions for C, D
Union
.... till 4 unions. all tables are residing in the local Database and not having records more than 50,000.
If I execute above insert in a DBMS job, it results into suppose 50 records where as if I execute the select query it gives 56 records.
We observed following things-
a) no issue with size of tablespace
b) no error while inserting
c) since query takes lot of time so we have not used Cursor and PLSQL block for inserting.
d) this discrepancy in number of records happens frequently but not everytime.
e) examined the records left out from the insert, there we couldn't find any specific pattern.
f) there is no constraint on the table X in which we are trying to insert. Also tables A, B, C....
I went through this thread -SQL insert with select statement having strange results but mainly users are having either DB Links or comparison of literal dates, in my case there is none.
Can somebody explain why is the discrepancy and what is the solution for it.
Or atleast some pointers how to proceed with the analysis.

Updated query and added more details

Since I am using Trunc() in the where clause so timing should not matter much. Also I manually ruled out records which were updated after the job run.

The first rule of troubleshooting is to not let your personal opinion get in the way of finding out what is wrong.
Actually this code, and the process it represents, is the most likely CAUSE of the problem.
>
where trunc(updated_date) > = trunc(sysdate-3)
>
You CANNOT reliably use columns like UPDATED_DATE to select records for processing. Your process is flawed.
The value of that column is NOT the date/time that the data was actually committed; it is the date/time that the row was populated.
If you insert a row into a table right now, using SYSDATE (8am on 3/5/2013) and don't commit that row until April your process will NEVER see that 3/5/2013 date until April.
Here is the more typical scenario that I see all the time.
1. Data is inserted/updated all day long on 3/4/2013.
2. A column, for example UPDATED_DATE is given a value of SYSDATE (3/4/2013) in a query or by a trigger on the table.
3. The insert/update query takes place at 11:55 PM - so the SYSDATE values are for THE DAY THE QUERY BEGAN
4. The data pull begins at 12:05 am (on 3/5/2013 - just after midnight)
5. The transaction is COMMITTED at 12:10 AM (on 3/5/2013); 5 minutes after the data pull began.
That data extract in step 4 will NEVER see those records! They DO NOT EXIST when the data pull query is executed since they haven't been committed.
Even worse, the next nights data pull will not see them either! That is because the next pull will pull data for 3/5/2013 but those records have a date of 3/4/2013. They will never get processed.
>
Job timing is 4am and 10pm EST
>
Another wrinkle is when data is inserted/updated from different timezones and the UPDATED_DATE value is from the CLIENT pc or server. Then you can get even more data missed since the client dates may be hours different than the server date used for the data pull process.
DO NOT try to use UPDATED_DATE type columns to do delta extraction or you can have this issue.

Problem inserting a gif into a blob field in a table with sqldev / forms6i

Problem solved - For those that might be interested, the errors don't make much sense - the problem was with the gif. Seems that these 28 gifs plus the new scans were saved from the scanner with
GIF - LZW, Transparent color: 255
Converting them to Black and white allowed them to be loaded.
If anyone understands why, I'd like to know
glenn
I was previously having a problem deleting a row with a blob and it was suggested that I create the table using rowdependencies - which I did as follows.
CREATE TABLE "MDD"."MDD_FIGURE2"
(     "FG_FIGURENAME" VARCHAR2(18 BYTE),
     "FG_FIGURE" BLOB,
     CONSTRAINT "FG_FIGURENAME_NN" CHECK ("FG_FIGURENAME" IS NOT NULL) ENABLE
) ROWDEPENDENCIES;
Then I copied my data from my previous table with the following - and everything came across
INSERT INTO MDD_FIGURE2 (fg_figurename, fg_figure)
SELECT FIG_FIGNAME, FIG_FIGURE FROM MDD_FIGURE;
mdd_figure2 was then renamed to mdd_figure
The table, Mdd_Figure, already contains some 2000+ .gifs that were successfully loaded with Forms 6i (yes, I know it is old, but I am stuck with having to use it). All the .gifs I am loading are from scans and all are less than 64k. However, 28 .gifs would not load. When I insert the .gif into the field and committed the form, the status message tells me a record was written but when I check it, the blob is empty.
So, when I try to insert one of these problem .gifs in SqlDeveloper, I open the new mdd_figure table, select the blob field, open the edit dialog, set it to figure, select the .gif that I want to load and then save it. The blob field changes from NULL to BLOB, but it is empty. When I try to commit, I get the following error from SqlDev.
UPDATE "MDD"."MDD_FIGURE" SET WHERE ROWID = 'AAAOeWAAEAAABAlAAz' AND ORA_ROWSCN = '358136842'
One error saving changes to table "MDD"."MDD_FIGURE":
Row 14: ORA-01410: invalid ROWID
I use rollback to restore the record to it's previous state.
If I load one of the successfully loaded .gifs into the same field, it loads perfectly as follows.
UPDATE "MDD"."MDD_FIGURE" SET WHERE ROWID = 'AAAOeWAAEAAABAoAAp' AND ORA_ROWSCN = '358136522'
Commit Successful
It appears the 28 gifs have a problem. I've re-scanned them, with the same results. They are just small scanned line map images from our earlier publications. They view properly in several different graphics programs and I can't find anything wrong with them.
I notice that the ROWID's are different while the ORA_ROWSCN's are the same - but what is the significance of that?
Any suggestions as to what is happening and what I can do about it?
Thanks for any help you can give me.

Error displaying a jpg file loaded into a table with blob field

This may not be the correct forum for this question, but if it isn't could someone direct me to the correct one.
I have created a table with a blob field in which I have loaded a jpg image. This appeared to work correctly, but when I try to display the image in internet explorer it comes back and tells me that it doesn't recognize the file type. Enclosed is the table create, load, and display pl/sql code. Can anyone tell me what I am doing wrong. Thanks. For the mime/header I used owa_util.mime_header('images/jpg') because my image is a jpg file.
The database is 10g
-- Create table
create table PHOTOS

IMAGE BLOB,

v_amt := 4096;
END LOOP;
dbms_lob.CLOSE(Photo);
EXCEPTION
WHEN NO_DATA_FOUND THEN
NULL;
END;
END;
The url I enter is: http://webdev:7777/tisinfo/tis.tiss0011.Display_Image?p_id=1

Just a little more information. When I enter owa_util.mime_header('image/jpeg') I can't display the file. It just shows up with a red x for the file.
When I enter owa_util.mime_header('image/jpg') it displays the file, but in the format
¿¿¿¿JFIF¿¿-Intel(R) JPEG Library, version [2.0.16.48]¿¿C
This is the way I would expect it to look if I opened it with Notepad, or an application that doesn't recognize jpg files. Can anyone tell me what I am doing wrong?? Thanks.

Problem with update of BLOB field in a table with compound primary key

Hi,
I've been developing an application in Application Express 3.1.2.00.02 that includes processing of BLOB data in one of the tables (ZPRAVA). Unfortunately, I've come across a strange behaviour when I tried to update value in a BLOB field for an existing record via a DML form process. Insert of a new record including the BLOB value is OK (the binary file uploads upon submiting the form without any problems). I haven't changed the DML process in any way. The form update process used to work perfectly before I'd included the BLOB field. Since than, I keep on getting this error when trying to update the BLOB field:
ORA-20505: Error in DML: p_rowid=3, p_alt_rowid=ID, p_rowid2=CZ000001, p_alt_rowid2=PR_ID. ORA-01008: not all variables bound
Unable to process row of table ZPRAVA.
OK
Some time ago, I've already created another application where I used similar form that operated on a BLOB field without problems. The only, but maybe very important, difference between both the cases is that the first sucessfull one is based on a table with a standard one-column primary key whereas the second (problematic one) uses a table with compound (composite) two-column PK (two varchar2 fields: ID, PR_ID).
In both cases, I've followed this tutorial: [http://www.oracle.com/technology/obe/apex/apex31nf/apex31blob.htm]).
Can anybody confirm my suspicion that Automatic Row Processing (DML) can be used for updating BLOB fields within tables with only single-column primary keys?
Thanks in advance.
Zdenek

Is there a chance that the bug will be included in the next patch?No, this fix will be in the next full version, 3.2.
