Blob datatype as arguement to PL/SQL procedure

Hi,
Iam trying to pass Blob data from application program to PL/SQL as one of its arguement. The PL/SQL procedure will inturn insert the given Blob data into appropriate table in its corresponding Blob column.
Ex:-
PL/SQL Procedure:
CREATE OR REPLACE PACKAGE TestPkg as
PROCEDURE logData
data IN Blob
END TestPkg;
Application Program:
1. string sqlStmt="BEGIN TestPkg.logData(:1); END;";
2. Connection * pConnection = getConnection();
3. Statement * pStatement = pConnection->createStatement(sqlStmt);
4. Blob blob(pConnection);
5. blob.setEmpty();
6. blob.write(100, pBuffer, 100, 1); <=== This results in (ORA-22275: invalid LOB locator specified)
7. pStatement->setBlob(blob);
8. pStatement->executeUpdate();
9. pConnection->terminateStatement(pStatement);
10. releaseConnection(pConnection);
I used to get similar error while directly inserting from application program to a table with Blob column.
We fixed it by using the "FOR UPDATE" clause in a select statement and obtaining the locator
for LOB. Iam looking for a similar syntax for PL/SQL procedure inputs.

Gaurav,
Just a guess, but try the following:
ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor( "SCOTT.HEADER_UPLOAD_TAB", oracleconnection );In other words, prefix the data-type name, HEADER_UPLOAD_TAB, with its schema owner name.
Good Luck,
Avi.

Assigning server file to Blob variable in pl/sql procedure

I have a file on the Unix box say 'test.txt' at '/temp/..'(path) which might be of a any size(which is not known), Now I wanted to read & open that file into a Blob variable in my pl/sql procedure. How can I do that ?
Can any one please help me....
Thanks

How can i make a pl/sql function for BLOB datatype

hi..anyone here who is very familiar about BLOB datatype. i have a COLUMN_ID, COLUMN_A in a certain TABLE_1. COLUMN_A is blob datatype that contains almost 250,000rows
SQL>select column_A from table_1 where column_id=1234567
column_A
00000001000000010000000606D4E833074B69EC06D4E91F074CO18406D50C58074C031E
how can i make a user-defined function to compute and convert this blob datatype into decimal length value. this hex value are points in the map.. the function must contain
1.get the length of a blob then
2.convert blob to variable hexadecimal characters by parsing it into 8
3.to_number function or other function used to convert haxadecimal characters to decimal numbers
4.phythagorean formula to compute length between two points. this is the formula i think LENGTH =
SQRT(power((coordinate_x-prev_coordinate_x),2)+power((coordinate_y-prev_y),2));
after this when i type this
SQL>select user_function(column_A) from table_1 where column_id=1234567
user_functions(column_A)
--output length will be in decimal value already
the function will goes like this
step1 is to get the blob length
00000001000000010000000606D4E833074B69EC06D4E91F074CO18406D50C58074C031E
step2 is parsing of data by eights
00000001 =>1
00000001 =>1
00000006 =>6 (number of coordinates)
06D4E833 => X1
074B69EC => Y1
06D4E91F => X2
074CO184 => Y2
06D50C58 => X3
074C031E => Y3
step3 to_number function used to convert hex char to decimal
step4 compute by phytagorean (NOTE ! when computing length the third parsed eight will tell how many coordinates are there..the number of coordinates is ranging from 2 up to E..above example shows 6 coordinates so it means
LENGTH1 =
SQRT(power((X2-X1),2)+power((Y2-Y1),2));
LENGTH2=
SQRT(power((X3-X2),2)+power((Y3-Y2),2));
TOTAL LENGTH=LENGTH1 + LENGTH2
thanks

its my first time to use that.There's got to be a first tiem for anything. Be brave.
btw if theres more easy suggestion pls feel free..Well of course the easiest solution would be if the calling program passed in the parameters as separate arguments instead of glomming them together in a string that has to be parsed. This sort of kluj really ought not to have survived into C21.

Passing variable of size greater than 32767 from Pro*C to PL/SQL procedure

Hi,
I am trying to pass a variable os size greater than 32767 from Pro*C to an SQL procedure.I tried assigning the host variable directly to a CLOB in the SQL section but nothing happens.In the below code the size of l_var1 is 33000.PROC_DATA is a procedure that takes CLOB as input and gives the other three(Data,Err_Code,Err_Msg) as output.These variables are declared globally.
Process_Data(char* l_var1)
EXEC SQL EXECUTE
DECLARE
l_clob clob;
BEGIN
l_clob := :l_var1
PROC_DATA(l_clob,:Data,:Err_Code,:Err_Msg) ;
COMMIT;
END;
END-EXEC;
I also tried using DBMS_LOB.This was the code that i used.
Process_Data(char* l_var1)
EXEC SQL EXECUTE
DECLARE
l_clob clob;
BEGIN
DBMS_LOB.CREATETEMPORARY(l_clob,TRUE);
DBMS_LOB.OPEN(l_clob,dbms_lob.lob_readwrite);
DBMS_LOB.WRITE (l_clob, LENGTH (:l_var1), 1,:l_var1);
PROC_DATA(l_clob,:Data,:Err_Code,:Err_Msg) ;
COMMIT;
END;
END-EXEC;
Here since DBMS_LOB packages allow a maximum of 32767,the value of l_var1 is not being assigned to l_clob.
I am able to do the above process provided i split l_var1 into two variables and then append to l_clob using WRITEAPPEND.i.e l_var1 is 32000 in length and l_var2 contains the rest.
Process_Data(char* l_var1,char* l_var2)
EXEC SQL EXECUTE
DECLARE
l_clob clob;
BEGIN
dbms_lob.createtemporary(l_clob,TRUE);
dbms_lob.OPEN(l_clob,dbms_lob.lob_readwrite);
DBMS_LOB.WRITE (l_clob, LENGTH (:l_var1), 1,:l_var1);
DBMS_LOB.WRITEAPPEND (l_clob, LENGTH(:l_var2), :l_var2);
PROC_DATA(l_clob,:Data,:Err_Code,:Err_Msg) ;
COMMIT;
END;
END-EXEC;
But the above code requires dynamic memory allocation in Pro*C which i would like to avoid.Could you let me know if there is any other way to perform the above?

Hi,
The Long Datatype has been deprecated use Clob or Blob. This will solve lot of problems inherent with the datatype.

Reading contents of a BLOB datatype having more than 4000 characters.

Hi,
I am unable to read contents of a column having BLOB datatype.I tried using ult_raw.cast_varchar2(Col_name) procedure,but since varchar2 has a size limit of 4000 bytes,complete contents are not visible.
Pl. suggest some way to view the contents.
Regards,
Saket Bansal

In the link that you mentioned a procedure is used that gets the length first then loops through if length is greater than 32760.
I mean to say can user get the output in a single SQL query e.g.
select utl_raw.cast_to_varchar2(column_name) from table_name;something like this for bytes greater than 4000 bytes.
----- Read your reply a bit late thanks.

Generating an xml from a pl/sql procedure

Hi Friends,
I have come up with a requirement to generate an xml from a pl/sql procedure.
I did some R & D and also got some sample procedures but could not understand the datatypes being used.
The procedure declares variables like this:
doc xmldom.DOMDocument;
mainNode xmldom.DOMNode;
headerElem xmldom.DOMElement; Pls could anyone tell what do these xmldom.DOMDocument, xmldom.DOMNode and xmldom.DOMElement mean?
Later in the procedure, these variables are assigned values like
doc := xmldom.newDOMDocument;
mainNode := xmldom.makenode(doc); This went a bouncer on me.
Pls help.
Thanks in advance ...!

Passing Queries to PL/SQL procedures

Hi,
Is there any way in PL/SQL procedure that i can pass two Queries Texts as parameters and return the result set by taking MINUS of the rwo Query results.
Thanx in Advace

Here is the principle...

Cannot view BLOB datatypes in Oracle10g

After a successful upgrade from Oracle8i to Oracle10g, I cannot view tables with BLOB datatypes. I'm getting the following error in SQL*PLUS upon quering the table:
SP2-0678: Column or attribute type can not be displayed by SQL*Plus
When i try to do the same thing from TOAD, I'm getting this error instead:
A Query with LOB's requires OC18 mode, but OC17 mode is used.
I have also tried to create a new table with BLOB datatype (since i thought the culprit was a broken migrated data) but I got the same error. What am I missing here????

Hy,
you never could view blobs via sqlplus
you only could use utl_raw.cast_to_varchar2 if there ist text inside your blobs.

ORA-01458 error while using Pro*C to invoke PL/SQL procedure, pls help

I am using Pro*C (Oracle 10g on Itanium platform) to invoke PL/SQL procedure to read RAW data from database, but always encoutered ORA-01458 error message.
Here is the snippet of Pro*C code:

When I test the PL/SQL code seperately, everything is ok, but if I use the Pro*C code to read, the ORA-01458 always happen, unless I change the SIZE_DATA_SEG value to 4000, then it passes, and the result read out also seems ok, either the bigger or smaller value will encounter ORA-01458.
I think the problem should happen between the mapping from internal datatype to external VARRAW type, but cannot understand why 4000 bytes buffer will be ok, is it related to some NLS_LANG settings, anyone can help me to resolve this problme, thanks a lot!

It seems that I found the way to avoid this error. Now each time before I read RAW(2000) data from database, i initialize the VARRAW.len first, set its value to SIZE_DATA_SEG, i.e., the outside buffer size, then the error disappear.
Oracle seems to need this information to handle its data mapping, but why output variable also needs this initialization, cannot precompiler get this from the definition of VARRAW structure?
Anyone have some suggestion?

the above code executes till the message :---IBEUtil.log("oracle.apps.ibe.shoppingcart.util.OrderUploadCSVReader", s, "before new array");
after that it gives error as :---Exception=java.sql.SQLException: Fail to convert to internal representation
Kindly Help....
Thanks in advance
Gaurav

Gaurav,
Just a guess, but try the following:
ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor( "SCOTT.HEADER_UPLOAD_TAB", oracleconnection );In other words, prefix the data-type name, HEADER_UPLOAD_TAB, with its schema owner name.
Good Luck,
Avi.

Problem with special chars in BLOB datatype using contains keyword

Facing problem, when part searching with special chars in BLOB datatype. It is considering the non alpha-numeric chars as a separtor in a provided string
EX:
SELECT *
FROM RESUME_TEST P,grst_candidate d
WHERE d.candidate_id = p.candidate_id
AND CONTAINS(P.CAND_RESUME,'%VB.NET%',1) > 0
Strings: , VB.NET , PL/SQL AS/400 , C etc..
Followed the below approaches
1) created a table:
Syntax: create table resume_Test(cand_id number(10),cand_resume blob);
2) inserted the values into this table upto 60,000
3) created a context index
3.1 created preferences
Syntax:
BEGIN
ctx_ddl.create_preference('try_lexer3','BASIC_LEXER');
ctx_ddl.set_attribute('try_lexer3','printjoins','-_~!@#$%^&*(){}[],=?\;|><.+');
END;
3.2 created context index
Syntax:
CREATE INDEX CANDRESUME_CTX_IDX ON resume_test (cand_resume)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS ('LEXER try_lexer3 memory 500M');
4) while executing this index, it is taking much time approx 6 hrs(plz explain why it is taking time)
5) Problems:
5.1 when searching with string(VB.NET , PL/SQL AS/400 , C etc..) it is considering the special char as a separator
5.2 used escape char (\) also, but no effect
5.3 when searching with single char, it is giving error (ORA-29902,ORA-20000,DRG-51030)
5.4 getting the above error with wild card chars (& ,_, (),{},[])
So, please explain the clear scenarios, why am getting this error , and how to get the proper results.

Have you tried adding the / char to the printjoin characters?
Indexing can take a lot of time, depending on the amount of data and your machine's power. You could try to parallelize the index creation and / or assign more memory
CREATE INDEX CANDRESUME_CTX_IDX ON resume_test (cand_resume)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS ('LEXER try_lexer3 memory 2000M') PARALLEL 8;

How we handle CLOB and BLOB Datatypes in HANA DB

Dear HANA Gurus,
We have would like to build EDW using HANA base on our source system Oracle and it's supports CLOB and BLOB datatypes
Would you please suggest how do we handle in HANA DB.
Let not say it's oracle specific.
Regards,
Manoj

Hello,
check SAP HANA SQL Reference Guide for list of data types:
(page 14 - Classification of Data Types)
https://service.sap.com/~sapidb/011000358700000604922011
For this purpose might be useful following data types:
Large Object (LOB) Types
LOB (large objects) data types, CLOB, NCLOB and BLOB, are used to store a large amount of data such as text documents and images. The maximum size of an LOB is 2 GB.
BLOB
The BLOB data type is used to store large binary data.
CLOB
The CLOB data type is used to store large ASCII character data.
NCLOB
The NCLOB data type is used to store a large Unicode character object.

Redirect From PL/SQL Procedure

Hi
I hope this is a relatively straightforward question, but I am having trouble getting a page redirect to work from a PL/SQL procedure.
I call the following procedure:-
CREATE OR REPLACE PROCEDURE DOWNLOAD_FILE(p_id NUMBER) AS
v_mime VARCHAR2(200);
v_length NUMBER;
v_file_name VARCHAR2(2000);
lob_loc BLOB;
v_session VARCHAR2(100);
BEGIN
v_session := v('SESSION');
SELECT MIME_TYPE,
FILE_CONTENT,
FILE_NAME,
DBMS_LOB.GETLENGTH(FILE_CONTENT)
INTO v_mime,
lob_loc,
v_file_name,
v_length
FROM SRGSUP_UPLOADED_FILES
WHERE ID = p_id;
owa_util.mime_header(nvl(v_mime,'application/octet'),FALSE);
htp.p('Content-length: ' || v_length);
htp.p('Content-Disposition: attachment; filename="' || v_file_name || '"');
owa_util.http_header_close;
wpg_docload.download_file(lob_loc);
EXCEPTION
WHEN NO_DATA_FOUND THEN
htp.p('Location: f?p=107:30');
END DOWNLOAD_FILE;
From the following HTML Expression in column formatting of a report:-
#FILE_NAME#: [ <a href="#OWNER#.DOWNLOAD_FILE?p_id=#FILE_ID#">Download</a> ]
When the table SRGSUP_UPLOADED_FILES contains the relevant document the file download works perfectly. However, if there is no file present I wanted the page to redirect back to itself. Instead it goes to the login page.
Initially I thought it was losing the session details so I tried "htp.p('Location: f?p=107:30:'||v('SESSION'));" but this made no difference.
Any help would be appreciated.
Thanks
Chris
