Throwing exceptions in PL/SQL

Hi friends

I have the following code:

declare

var1...
var2...
cursor c1

Start

Insert stmt;

Update stmt;

Update stmt;

to r1 c1 loop
end loop;

end;

Each month I will be having about 6 million lines in the process. In order to throw exceptions, I think of one of the following options:

Option 1_
declare

var1...
var2...
var3 exception;
var4 exception;
VAR5 exception;

cursor c1

Start

Insert stmt;

Update stmt;
IF SQL % NOTFOUND then
var3;
end if;

Update stmt;

IF SQL % NOTFOUND then
var4;
end if;

to r1 c1 loop
end loop;

IF SQL % NOTFOUND then
VAR5;
end if;

Exception
When var3 then blah blah
When var4 then blah blah
When var5 then blah blah

end;

Option 2_

declare

var1...
var2...

cursor c1

Start

Insert stmt;

Update stmt;

Update stmt;

to r1 c1 loop
end loop;

Exception
While some other then blah blah
end;

In terms of performance, which is better? And is there a better option?

Thank you...

Ways to handle exceptions known or predictable management of exceptions.

The use of OTHERS WHEN in most cases implies that you don't know what exceptions will occur and so it's a bad habit.

It is always better to define known exceptions and capture those explicitly and manage them properly. Then, if any exception occurs, she really is and the exception and should cause the program to fail and certainly should not be ignored, because it was not intended.

I have a public method in my AM I want to expose as a client method to call from a managed bean.

I have a method like signature

public Long myMethod (String val);

If I go to AM and click the Edit then I see this method on the left side of the shuttle to expose it.

But as soon as I add bird Exception this method is no longer available.

So why does this happen?

EXECUTE IMMEDIATE throws exception NO_DATA_FOUND when it should not

Hi all

I wrote an anonymous PL/SQL block that, on paper, should be OK, but one of its commands EXECUTE IMMEDIATE is runnning slowing prematurely and throw an exception NO_DATA_FOUND, when it should not because I know that there is data in the table.

Here is the line that I suspect is out of steam after 8 attempts:

---
immediately execute "INSERT INTO ple101.circular35 (ID, SLAVETABLEID, SLAVEITEMID, MASTERTABLEID, MASTERITEMID, PRO) (SELECT * FROM SLAVETASKS where mastertableid =' |)" subTableID | "and masteritemid =' |" subitemID |' and subtableid =' | mastTableID | "and SLAVEITEMID =' |" mastItemId |') ' ;
------

It is supposed to search the entire SLAVETASKS table for documents that match the WHERE clause, but gives up after 8 cycles.
Table SLAVETASKS got 10228 records.

The above statement (and the whole of the PLSQL block) is good in that it gets records if they are wthin the first 8 records in the SLAVETASKS table, but like I said after 8 records, to throw an exception NO_DATA_FOUND.

Hi Goofy,

The above script is for PLSQL and if you want to display the data in circular 35 follow like that

# Save the code below in the sqlscript for example. circular_process_display. SQL and run as

sqlplus /@ @circular_process_display.sql

-- CREATE TABLE circular 35
CREATE TABLE circular35
....
..
/

-- Execute PLSQL Block as given in my earlier post
DECLARE
...
BEGIN
...
EXCEPTION
...
END;
/

-- Run SQL to display output on screen.
SET SERVEROUTPUT ON SIZE 100000 FEEDBACK ON LINESIZE 200;

SELECT *
FROM circular35
/

setARRAYatName throws exception-> discussion of named parameter by default/now

Hi, I'm pretty new with the help of JDBC and
I have a question about using the following method of an OracleCallableStatement setARRAYatName, so I don't have to fill in default values (I guess this is corect?)
the signing of sqlmethod I call

PROCEDURE create_timecard_bb)
p_start_time IN hxc_time_building_blocks.start_time%TYPE,
p_stop_time IN hxc_time_building_blocks.stop_time%TYPE,
-p_approval_status IN hxc_time_building_blocks.approval_status%TYPE,
p_resource_id IN hxc_time_building_blocks.resource_id%TYPE,
-default to anyone because there is no other type of resource at the present time.
p_resource_type IN hxc_time_building_blocks.resource_type%TYPE
DEFAULT hxc_timecard.c_person_resource
-We can't use approval_style_name because it is not unique.
p_approval_style_id IN hxc_time_building_blocks.approval_style_id%TYPE
DEFAULT NULL,
p_comment_text IN hxc_time_building_blocks.comment_text%TYPE
DEFAULT NULL,
p_app_blocks hxc_block_table_type IN OUT NOCOPY,
p_time_building_block_id OUT NOCOPY hxc_time_building_blocks.time_building_block_id%TYPE
);

The following code works.

String stmtString = "start HXC_TIMESTORE_DEPOSIT.create_timecard_bb(?,?,?,?,?,?,?,?); end; « ;
cstmt = conn.prepareCall (stmtString) (OracleCallableStatement);
System.out.println (cstmt.getParameterMetaData (). GetParameterCount());
/ * FOLLOWIG CODE WORKS BUT IT IS WITH INDEX
*/
GregorianCalendar calendar = new GregorianCalendar();
Calendar.Set (2009, Calendar.JUNE, 1);
cstmt.setDate (1, java.sql.Date (calendar.getTime () .getTime ())) of new;
Calendar.Set (2009, Calendar.JUNE, 7);
cstmt.setDate (2, new java.sql.Date (calendar.getTime () .getTime ()));
cstmt.setInt (3, 4760);
cstmt.setString(4,"PERSON"); default value
cstmt.setInt (5,267); set, a value can also be null by default
cstmt.setNull VARCHAR (6); default value is normally zero
cstmt.setARRAY (table 7);
cstmt.registerOutParameter(8,INTEGER);
cstmt.registerOutParameter (TABLE 7, "HXC_BLOCK_TABLE_TYPE");

... during the extraction of results

the following does NOT work code and throws an exception that er is een parameternaam geprobeerd in you stellen die niet voorkomt in SQL code of. : p_app_blocks (translated: you have tried to assign a parametername which does not excist in sql code)

String stmtString = "start HXC_TIMESTORE_DEPOSIT.create_timecard_bb(?,?,?,?,?,?,?,?); end; « ;
cstmt = conn.prepareCall (stmtString) (OracleCallableStatement);
System.out.println (cstmt.getParameterMetaData (). GetParameterCount());
/ * the following code does not work, for arrayatname, difference which is parametesr with the default are not assigned by name, otherwise they are now affected by his name,

cstmt.setDate ("p_start_time", new java.sql.Date (calendar.getTime () .getTime ()));
Calendar.Set (2009, Calendar.JUNE, 7);
cstmt.setDate ("p_stop_time", new java.sql.Date (calendar.getTime () .getTime ()));
cstmt.setInt ("p_resource_id", 4760);
cstmt.setARRAYAtName ("p_app_blocks", array); <-DURATION says this line throws an exception
cstmt.registerOutParameter ("p_time_building_block_id", INTEGER);
cstmt.registerOutParameter ("p_app_blocks", ARRAY "HXC_BLOCK_TABLE_TYPE");

*/

So I make a false assumption that if you assign one with the name of those you do not assign a default value?
Or something is wrong with setARRAYAtName?

DeviceInfo.getDeviceName throws exceptions?

Hello

In my application I want to know what mobile, the application runs. Then I use the DeviceInfo functions.

But DeviceInfo.getDeviceName () sometimes throws an exception!

DeviceInfo.getDeviceId () a front line still works well.

InputStream in device throws exception SaxParser

Hi all, I am working on OS 5.0.

In my application, I have connected to the network using HttpConnection. I've added the necessary parameters to test the device. The connection sets up in the device, but it is throwing

'& #x1f' SaxParser invalid character exception

I don't know that that's the problem with InputStream, but not with the Httpconnection.

a strange beviour, I've observed while debugging in the Simulator is... When I pass a URL with parameters make me same thing '& #x1f' bad character SaxParser exception, but if I pass the direct URL without setting the XML file is the analysis and works very well.

any1 has faced previously this kind of problem? How to solve this problem?

If the data from the server is compressed, then you will need to decompress before feeding it to the parser. If the data are encoded with gzip (uncompressed), try something like this:
```
HttpConnectionFactory connFactory = new HttpConnectionFactory(_XMLUrl);connection = (HttpConnection)connFactory.getNextConnection();if (connection.getResponseCode() == HttpConnection.HTTP_OK) {    inputstream = new GZIPInputStream(connection.openInputStream());    parser.parse(new InputSource(inputstream));} else {    // error}
```
If the server really uses zip compression, then you will need to use a ZlibInputStream. It is less likely, because the zip compression is oriented file, while gzip is aligned flow and more commonly used for responses from the server.

A few other notes about your code:
1. you don't need to create an InputStreamReader; the Analyzer can understand the encoding of the data of the (inflated) input stream itself.
2. You must use connection.openInputStream () instead of connection.openDataInputStream (). Expect UTF-8 text, not Java data types, in the input stream.
3. Definition of the Content-Type request property is not make sense unless you publish data to _XMLUrl (which, from your code, you do not).
4. If the server powers up properly the response headers, you can check if the answer is gzip-ed using "gzip".equals (connection.getEncoding ()) after the call to connection.openInputStream (). " (My suggested code blindly guess gzip). Don't forget to check, however, that the process server is actually defining the header of the correct answer. many authors of server scripts don't know or are lazy about it. (If you control both sides, of course, you can safely be lazy.)
5. In your second example in code, you should probably be defining the request text/xml HEADER_ACCEPT, instead of HEADER_ACCEPT_ENCODING property. Typical values for Accept-Encoding are 'gzip', 'compress' and 'identity', not ' text/xml '.

Plugins and Java methods that throw exceptions

I am trying to determine how to deal with my plugin with expose an object method java which could raise and exception. For the example below, I've added a mapping object for the exception class and the getErrno and getReason methods
I have in my java script
try {}
Method.Invoke ();
}
{} catch (e)
errno = e.getErrno ();
}
the e I catch is going to be my java exception object, or is it something else?
When I run it (whose value invoke throws the exception) I get "TypeError: function getErrno is not found.

Basically, all exceptions are string message, not the exception objects. What you can do is to serialize the error and the message that the Exception string is the excpeptions object.

Help with «throw exception error native function»

Can someone help me find a soultion error with dreamweaver mx2004. I use the software successfully for several years and everything has started to develop a new site with .htm files.
When connecting to a css file, I get the following error when I swith from design mode, the system displays the error code, then crashes, but only on a single page, another page using the same css file works fine! I'm totally baffled...
The error is:
When executing command DW_DesignView in toolbars.xml, the following JavaScript error occurred: exception throw in native function

I hope that its not me, but it just may be, please help.

If this is the case with a single file, there is something wrong with this file. Or to be more precise, there is something in this file that gives indigestion to Dreamweaver. You must check the file with the validator W3C CSS (http://jigsaw.w3.org/css-validator/).

There is a known issue with Dreamweaver CS3, for which a file that is exactly 8 KB or multiples of it causes Dreamweaver to crash. I've never heard of him with Dreamweaver MX 2004, but if the file is valid, try to open it in a text editor and add something, as a CSS comment. This increases the size of the file and get rid of the problem.

If these ideas do not resolve the problem, I'm afraid, I'm out of ideas. Adobe will not help you because your version of Dreamweaver is no longer supported.

Help with the exception of Pl/SQL 'ora-3150 end of file on the communication channel.

Hello.
The code attached to this post opens a slider that load of 99 dblinks from different remote databases of different version.
He captures the information from these databases and stores them locally on a central database (11.2.0.4.0 version) on different tables.
The problem I have is that when a database is deleted, the dblink to this database show me the error 'ora-3150 end of file on communication channel' and that's right.
But he's not going trough the exception that I created, the cursor is closed and does not continue with the cycle.
The exception I created insert data on DBMONITOR error. DBMONITOR_LOG_ERROR_TABLE in order to catch the error (you'll be able to see all the code on the attachment)
It's the exception:

while others then
INSERT IN DBMONITOR. DBMONITOR_LOG_ERROR_TABLE (NOMBRE_DBLINK, message, info, FECHA_ERROR, TIPO_PROCEDURE) VALUES (var, SUBSTR (DBMS_UTILITY. (FORMAT_ERROR_STACK, 1, 200), "CONNECTION ERROR", SYSDATE, 'CAPACITY');
commit;
end;
Could help me please on how could intercept this exception?
Thank you.
Juan.

You might have a problem with your connection or mishandling. The end of the file ora-3150, on channel of communication error means that there is a connection, but this link was broken somehow.

If a database is not reachable, you should get other types of errors.

For example judgment of the Kingdom or tns - memory could not resolve alias or simliar things.

Here is a list of typical mistakes I have check and manage when accessing remote databases.
```
  e_db_link_broken EXCEPTION;  --ORA-02019 connection description for remote database not found
  PRAGMA EXCEPTION_INIT (e_db_link_broken, -02019);
  e_oracle_not_available EXCEPTION;  --ORA-01034 ORACLE not available
  PRAGMA EXCEPTION_INIT (e_oracle_not_available, -01034);
  e_oracle_down EXCEPTION;  --ORA-27101: shared memory realm does not exist
  PRAGMA EXCEPTION_INIT (e_oracle_down, -27101);
  e_no_listener EXCEPTION;  --ORA-12541: TNS:no listener
  PRAGMA EXCEPTION_INIT (e_no_listener, -12541);
  e_no_service EXCEPTION;  --ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
  PRAGMA EXCEPTION_INIT (e_no_service, -12514);
  e_timeout EXCEPTION;  --ORA-12170: TNS:Connect timeout occurred
  PRAGMA EXCEPTION_INIT (e_timeout, -12170);
```
If you have a long open session and fail to close the db links after recovered information from the remote site?

In addition, I propose to change your dynamic insertion in a normal insert.

First extract the data of the DB link dynamically, but just with a select statement. Then do the insertion with the result data.

Improve your logging table to store messages up to 4000 char CHARACTER. 200 is really small for error messages.

In addition to the DBMS_UTILITY. FORMAT_ERROR_STACK you must also connect DBMS_UTILITY. FORMAT_ERROR_BACKTRACE. Just to see if you get a better message there.
```
WHEN e_db_link_broken or e_oracle_not_available or e_oracle_down or e_no_listener or e_no_service or e_timeout THEN
   INSERT INTO DBMONITOR.DBMONITOR_LOG_ERROR_TABLE (NOMBRE_DBLINK, message, info,FECHA_ERROR,TIPO_PROCEDURE) VALUES(var, 'Remote DB not accessible','ERROR DE CONEXION',SYSDATE,'CAPACITY');
               -- commit;
WHEN OTHERS THEN

                INSERT INTO DBMONITOR.DBMONITOR_LOG_ERROR_TABLE (NOMBRE_DBLINK, message, info,FECHA_ERROR,TIPO_PROCEDURE) VALUES(var, SUBSTR(DBMS_UTILITY.FORMAT_ERROR_STACK||DBMS_UTILITY.FORMAT_ERROR_BACKTRACE, 1, 4000),'ERROR DE CONEXION',SYSDATE,'CAPACITY');
                --commit;
                end;

  values (:P1_USER_ID, v_errmsg);  

END;

When I set the exception inside the loop, as above, the procedure seems never to end, and I end up getting a 'NOWAIT' error when I try to remove the table or something like that.

The code works fine if I remove the 'START' just after the loop and also out of the exception within the loop, but I want to be able to specify what's wrong with each record rather than deal with the correct records and then stop after that it is a record that has, for example, 9 values in a column that accepts only 6.

Can anyone help with this?

Thank you

Play with my code I found what was wrong.

I needed to add in the following line in my code block of exception:

v_line := NULL; v_sr_no := v_sr_no + 1;

Final code:

  v_char      CHAR(1);
  c_chunk_len   number       := 1;
  v_line        VARCHAR2 (32767)        := NULL;
  v_data_array      wwv_flow_global.vc_arr2;
  v_rows number;
  v_sr_no number := 1;
  v_first_line_done boolean := false;
  v_error_cd number :=0;
  v_quote_pos1 NUMBER;
  v_quote_pos2 NUMBER;
  v_enclosed_str VARCHAR(200);
  v_errmsg VARCHAR2(4000);
