Stored Procedure or function to extract Blob

How can I extract Blob from Oracle to the way it was inserted in the db ? I tried using utl_raw but it gave me "Buffer too small"
ERROR at line 1:
ORA-22835: Buffer too small for CLOB to CHAR or BLOB to RAW conversion (actual:
236143, maximum: 2000)

I am trying this but it's not working for some reason:
create or replace function F(B BLOB)
return clob is
c clob;
n number;
begin
if (b is null) then
return null;
end if;
if (length(b)=0) then
return empty_clob();
end if;
dbms_lob.createtemporary(c,true);
n:=1;
while (n+32767<=length(b)) loop
dbms_lob.writeappend(c,32767,utl_raw.cast_to_varchar2(dbms_lob.substr(b,32767,n)));
n:=n+32767;
end loop;
dbms_lob.writeappend(c,length(b)-n+1,utl_raw.cast_to_varchar2(dbms_lob.substr(b,length(b)-n+1,n)));
return c;
end;
I get ORA-22921: length of input buffer is smaller than amount requested
ORA-06512: at "SYS.DBMS_LOB", line 833
ORA-06512: at "SYS.F", line 15

Java Stored Procedure via Function Give 0RA 600 from SQL Workshop and App

Hi,
Anyone experienced stored procedures or functions failing when called from APEX app or SQL Workshop ( ora 600 ) yet they work fine when called from SQLPlus?
Sqlplus connected as my apex workspace schema owner:
select net_services.test_db_connection_via_ldap(
'APEXPRD1', 'test1', 'test1', null ) as result from dual;
RESULT
The database connection attempt was SUCCESSFUL

You could be right in your guess that the error is related to MTS. Search Metalink for '16371'. Why not switch your APEX app to use OHS and test whether the error persists. ?

Diif between Stored procedure and function

HI
I want all the differences between Stored procedure and function.
Even the basic diff is Procedure does not return any value and Function must be...
Thansk In advance...

1) Functions are used for computations where as procedures can be used for performing business logic That's an opinion on usage not an actual difference.
3) You can have DML(insert,update, delete) statements in a function. But, you can not call such a function in a SQL query.Not true. As User defind functons limitations we can use a function that issues DML in a SELECT statement, if it uses the PRAGMA AUTONOMOUS_TRANSACTION.
4) Function parameters are always IN, no OUT is possibleEasily refutable...
SQL> CREATE OR REPLACE FUNCTION my_f (p OUT NUMBER) RETURN DATE
2 AS
3 BEGIN
4     p := to_number(to_char(sysdate, 'DD'));
5     RETURN sysdate;
6 END;
7 /
Function created.
SQL> var x number
SQL> var d varchar2(18)
SQL> exec :d := my_f(:x)
PL/SQL procedure successfully completed.
SQL> print d

18-NOV-05
SQL> print x
         X
        18

Stored Procedure :supports deffered name resoultion Example while writing a stored procedure that uses table named tabl1 and tabl2
etc..but actually not exists in database is allowed only in during creationNot sure what this one is about...
SQL> CREATE PROCEDURE my_p AS

7) A procedure may modifiy an object where a function can only return a value.An ounce of test is worth sixteen tons of assertion...
SQL> CREATE OR REPLACE FUNCTION my_f2 RETURN VARCHAR2
2 AS
3 BEGIN
4       EXECUTE IMMEDIATE 'CREATE TABLE what_ever (col1 number)';
5      RETURN 'OK!';
6 END;

SQL> I think there are only two differences between a procedure and a function.
(1) A function must return a value
(2) because of (1) we can use functions in SQL statements.
There are some minor difference in allowable syntax but they are to do withj RETURN values.

Stored procedure and function - return table type

Hello again :)
I have one simple question :) Maybe on this forum the question was asked, but I found only similar question and they didn't help me.
It's possible return in Stored Function (with StoredProcedureFunction) as result return TABLE type? Or return table type with output parametr with Stored Procedure? Or instead of the table return the db object, but it is similar problem:)
Now, I can using db types TABLES or DB OBJECTS as INPUT parameters with call stored functions or procedures, for example:
I have this simple db object:
create or replace type BUFFER_DATA_R as object( detail VARCHAR2(4000 ))
And this simple table:
CREATE OR REPLACE TYPE BUFFER_DATA_T IS TABLE OF BUFFER_DATA_R
I create simple domain class object:
*public class DMBufferDataStruct {*
public String bufferData;
And I mapped in java with ObjectRelationalDataTypeDescriptor:
ObjectRelationalDataTypeDescriptor descriptor = new ObjectRelationalDataTypeDescriptor();
descriptor.setJavaClass(DMBufferDataStruct.class);
descriptor.setTableName("BUFFER_DATA_T");
descriptor.setStructureName("BUFFER_DATA_R");
descriptor.setPrimaryKeyFieldName("DETAIL");
descriptor.addFieldOrdering("DETAIL");
descriptor.addDirectMapping("bufferData", "DETAIL");
and join to server session ...
Well, i using this doimain class object as input parametr wih stored procedure call:
ObjectRelationalDatabaseField ordf = new ObjectRelationalDatabaseField("");
ordf.setSqlType(Types.STRUCT);
spCall.addNamedArgument(key, key,
Types.ARRAY,
"BUFFER_DATA_T",
ordf);
query.addArgument(key);
args.add(paramsInputs.get(key));
in paramsInputs is Vector of DMBufferDataStruct...
Well, this work fine!
But I can not figure, how to return this table from output parameters of stored procedure or as a return value from stored function?
Example of exceptions:
The number of arguments provided to the query for execution does not match the number of arguments in the query definition. - return as output parameter
PLS-00382: expression is of wrong type - used as result from stored function
So, my question is: Is possible return this table type from stored procedure or function? And if YES, how can I set output argument for call?
Thx advance!
Sorry for my English! :)
Best regards, KLD

Your question is: what is faster PL/SQL or PL/SQL? And the answer is: it is PL/SQL of course!
As a general rule, you use a function when you return exactly one result: a number or a string or (more complex) instance of an object type or REF CURSOR or PL/SQL collection.
You use a procedure when:
a) you just do the job and return no result
b) you return multiple results - you can use multiple IN/OUT or OUT parameters
Imagine you have to write a program unit that performs a partitioned table maintenance by adding a partition.
You can implement this unit:
a) if you want return a "status code" (0 on successful completion or non-zero in case of error) then you should use a function
b) if you want no "status code" (in case of error an exception is raised that is handled outside of the program unit) then you should use a procedure
c) if you want "status code", name of tablespace where a partition was created (assume you program is so complex that it can choose different tablespaces based on metadata and free space available) and free space in that tablespace after the creation of a new partition then you should use a procedure with 3 OUT parameters.
But these are good programming practices that can be applied to (almost) any 3rd generation programming language, not only PL/SQL.

How to get a list of values used in the WHERE filter of stored procedures and functions in SQL Server

How can I get a list of values (one or more) used in the WHERE filter of stored procedures and functions in SQL Server?
How can get a list of values as shown (highlighted) in the sample stored procedure below?

Lenfinkel

Hi LenFinkel,
May I know what is purpose of this requirement, as olaf said,you may parse the T-SQL code (or the execution plan), which is not that easy.
I have noticed that the condition values in your Stored Procedure(SP) are hard coded and among them there is a date values, I believe some day you may have to alter the SP when the date expires. So why not declare 3 parameters of the SP instead hard coding?
For multiple values paramter you can use a
table-valued parameter. Then there's no problem getting the values.
If you could elaborate your purpose, we may help to find better workaround.

Sender JDBC with Stored Procedure or Function

Hi.
I have a problem to update a row that I obtain from sender JDBC (using SELECT or calling to a FUNCTION).
As the consultation is so complex and the table has fed up transactions, often it takes the registry A and updates register B.
Try to use the level of transaction Serializable (/people/yining.mao/blog/2006/09/13/tips-and-tutorial-for-sender-jdbc-adapter) but it throws the following error to me:
"The JDBC driver returned the following error message: 'java.sql.SQLException: ORA-08177: can't serialize access for this transaction '. For details, contact your database server vendor."
Try to invoke to a function (/people/jegathees.waran/blog/2007/03/02/oracle-table-functions-and-jdbc-sender-adapter) but when placing a sentence of UPDATE within the function throws an error, I reviewed to me and calling to a function from a SELECT, Oracle it does not allow to modify registries of the database.
Some other suggestion?

Hi,
See this link,
Here is an example of mapping for synch JDBC.

UCCX 8 - Custom Stored Procedure Not Functioning

Hello,
We're trying to modify one of the agent summary reports in UCCX 8. We want the outbound report to only show numbers that were external calls. (Longer than 4 digits.) We copied and modified the existing stored procedure and it seems to run ok until we try to use it in the historical reporter. HR reports that the stored procedure cannot be found. We've followed what documentation we could find about adding one but can't get it working. We've been using ASG Server Studio to access the database. We opened a TAC case but haven't gotten anywhere. Here's the detail we gave them.

I have created a stored procedure on the informix DB for UCCX 8. i have
been following the Historical reporting admin guide. the SP runs fine when i use ASG
server studio. when i try to use crystal reports to access the SP i get "Failed to
retrieve data from the database. Details: ADO Error code 0x80004005 Source: Microsoft OLE
DB Provider for ODBC Drivers Description: [Informix][Informix ODBC Driver][Informix]
Routine (sp_agent_call_summar_nointernal) can not be resolved. SQL State:S1000"
if i use a standard procedure Crystal Reports works fine.
i have the uccxHrUserRole assigned to the procedure so i do not understand why i cannot
run the SP.
Any ideas, we really need to get this working.
Thanks!

Hi
1) There are an impressive number of bugs in early 8.0 versions; on the initial release permissions were incorrect for the existing SPs so the uccxHrUser couldn't run them. You could copy them, so had to copy them and run the copies.. tedious.
If you are on a working version, the other gotcha is that you need to specify them fully-qualified - so sp-test would be db_cra.dbo.sp_test
Also note that the SPs are randomly split between 'functions' and 'procedures' (there may be a pattern, but I can't work it). Both are similar, but there is a field in the DB that marks a proc as a fucntion or a procedure - the informix Squirrel SQL plugin doesn't work well with this and just shows the ones marked as 'procedures'. I've had better luck with RazorSQL and have recently played with the free IBM Data Studio which I think also displayed them all.
2) You can't edit the permissions of existing ones, but you can add new ones and since you (well, uccxHrUser) is the owner you can set permissions on those. Try using RazorSQL or AGS Server Studio (which is better, but $$$) to add new procs.

SQL query statement for stored procedure / function listing ...

Hi everyone,
Is there a SQL query to list all the stored procedures and functions of an user in an Oracle 8 database?
I have this idea:
select * from USER_SOURCE where TYPE = 'PROCEDURE' or TYPE = 'FUNCTION'
but I am not too sure whether this is correct.
Thanks in advance,
Eric

Yeah
I agree with you Garcia , my above posting was a correction to the query mentioned in the question only.
you are correct
If you only want the name of the object,
SELECT Object_Name from User_Objects where object_type in ( 'PROCEDURE' ,'FUNCTION');
is much faster than Selecting (distinct) from User_Source.

Establishing database connection in stored procedures/functions

It's not the same how you implement the programs in java or .Net to create DB connection. It's different over here. You have use the DataBase Links in order to make to connection with another DB and use that Link in the stored procedure or function where ever its necessary as per your requirement.

Is it possible to make stored procedure which results with only one row?

Greetings community,
I’m making the app in .NET, and I don’t really have the problem to get the result, but through watching videos I’ve realized that using LINQ isn’t always the best way of doing things, because it requires pulling too much data through the
network to do some LINQ over it. There’s also the issue of security, so I was advised to use stored procedures and functions on SQL server to accomplish what I need without disturbing client machines too much.
I’m absolute beginner in TSQL, so I need your help. I need to extract last order of particular customer and I wonder if that could be accomplished. To make things simple, let’s imagine that my orders table has only these three columns:
OrderID (int, primary key, identity incremented), CustomerID (int), and DateOfOrder(datetime). I need a procedure that would take CustomerID as parameter, and return one single row which represent the last order of that customer.
I would also be very grateful to see the extended procedure that would take LastCount additional parameter and return several rows which would represent last several orders of that customer.
Last thing, if it’s not too much already, I would very appreciate some link to educational videos about SQL server for beginners. There were great videos on msdev.com, but this web address doesn’t exist anymore.

There are many tutorials on MSDN with Linq including SQL Server Express. A good start is this here:
