SQL & PL/SQL :: How To Handle The Exception
May 19, 2011
The following code is working fine,But the thing is if column already exists in the table,then also the other statements should be executed instead of coming out of procedure.SO how can I handle that exception??
SQL> CREATE OR REPLACE PROCEDURE sp_execparameters(tname IN VARCHAR2,
colname IN VARCHAR2,datatype IN VARCHAR2)
2 AS
3 v_sqlstr1 VARCHAR2(1000);
4 BEGIN
5 v_sqlstr1 := 'alter table '||tname||' add '||colname ||' '|| datatype ;
[code].........

APEX 4.2Oracle 11g Database We are using the standard exception handler that was introduced in APEX 4.1, and we have code in packages & procedures in the database (following proper processes of keeping code in the database where possible). When an exception is found in the procedures/ packages/functions, should the APEX application level exception handler catch any errors that occur or should they be handled in the package/procedure/function they occurred in? Why I ask if, we right now have exception handling code in the pl/code bodies BUT they write their errors to the same table that Apex's Exception handler does, but the errors are NOT presented to the user using the APEX exception handling mechanism.

I have to implement exception handling in the exception block of a trigger, Quote:exception
when ora_java.java_error then
message( 'Unable to call out to java, ' || ora_java.last_error );
ORA_JAVA.CLEAR_EXCEPTION;
when ORA_JAVA.EXCEPTION_THROWN then
ex := ORA_JAVA.LAST_EXCEPTION;
message( Exception_.toString(ex));
-- lv_exception := Exception_.getMessage(ex);
I get an error for the line: 'message( Exception_.toString(ex));'I have imported the java classes FException et IObject with their methods.
I have to create a Web Service Client, so I wonder if the paragraph Quote:when ORA_JAVA.EXCEPTION_THROWN then ex := ORA_ JAVA. LAST_ EXCEPTION; is mandatory.

I have a stored procedure that does a "select name into v_name" SQL statement, which works fine. The only problem is when the query finds no data (the procedure will error because there is no value to put into the variable). Now i have a work around to this by running the query first with a count statement (which will always have results) and then if it is not equal to 0, then i will run the select into.
My question is, is there a better way to handle this kind of issue?

we are using oracle database. We hold the company records in the database. The records of the company should be available at anytime but over years the database keeps growing. Now how to handle the old data. All the data is important but if this goes for few more years then we need more and more disk space to handle. Is there any efficient methodologies to handle the old data? For us old mean the data that is 10 year old.

I'm working on a plsql program and i'm using collections. I loop the collection and delete rows of it depending on the edits of my program. Here is the question.
if my collection holds
rows
[1]value
[2]value
[3]value
i can simply do something like FOR indx in invoice.first..invoice.lasthowever if i delete row 2 of my collection i get an error. no data found.
ive been researching this site
[URL].......
rows
[1]value
[3]value
[4]value
is there a way to tell plsql i just want it to loop the collection from top to bottom regardless of the index values?

I've set up Oracle Streams replication between multiple N-way zones like this:
CODE------------------------------
Nway1 |Intersect| Nway2
DB1 --|-- DB3 --|-- DB5 DB1, DB2, DB3, DB4 - N-way1
| | | | | DB3, DB4, DB5, DB6 - N-way2
DB2 --|-- DB4 --|-- DB6 DB3, DB4 - intersection zone
| |
-------------------------------
Physically DB1 .... DBN connected sequentially, so I want to prevent segmentation if some DB is unaccessible, but at the same time fight unneeded redundancy which uses too much link bandwidth to send N-1 LCR-s to all members of a single N-way group (so I want to split one big N-way zone into smaller ones and sequentially connect them into chain - it significantly reduces load on link if N is big enough (>10)). Also I want to have 2 DB in intersection zone to prevent single point of failure.
This scheme has one drawback - if change originated on DB3 or DB4, then it will be propagated (more correctly - applied and captured again) to DB5 and DB6 by both DB1 and DB2 (and, as far as I know, I have no means in capture rules to detect state of DB2 from DB1 and vise versa), so on DB5 and DB6 I get:
CODEORA-00001: unique constraint (DUMMYUSR.UNIQUE_RECORDS) violated error
I've set up standard conflict handler for apply process:
CODE
declare
cols DBMS_UTILITY.NAME_ARRAY;
begin
cols(1) := 'no';
cols(2) := 'name';
cols(3) := 'ddate';
dbms_apply_adm.set_update_conflict_handler(
object_name => 'DUMMYUSR.DUMMYTBL',
method_name => 'DISCARD',
resolution_column => 'no',
column_list => cols
);
end;
but it seems that it does not handle uniqueness conflicts. What is the best way to handle uniqueness conflict (is there a better way than to write custom error handler) and how serious is the impact on insert performance of having unique constraint and corresponding error handler. (In real world I will have to deal with tables with metainformation and without any keys).
Also, how to proceed with no error or raise exception from apply error handler with error that caused this handler to run? In oracle docs I can find only example that modifies LCR and runs lcr.EXECUTE(TRUE), but what to do if I don't want to reexecute LCR, but merely check error code and propagate error if it is not ORA-00001?

I created a custom type what it has a clob member variable:
CREATE TYPE custom_type AS OBJECT(
c_type INTEGER,
c_number NUMBER(38, 8),
c_varchar2 VARCHAR2(4000 CHAR),
c_clob CLOB,
[code]........
The inserting and updating works with constructor: ... custom_type (to_clob('foo')) . But if the data is longest than 4000 characters then the PHP isn't access to it.
So:
The normal case:
$sql = ("INSERT INTO table ( clob_field ) VALUES ( EMPTY_CLOB() ) RETURNING clob_field INTO :clob");
$stid = oci_parse($conn, $sql);
$clobdescr = oci_new_descriptor($conn, OCI_DTYPE_LOB);
oci_bind_by_name($stid, ':clob', $clobdescr, -1, OCI_B_CLOB);
oci_execute($stid);
$clobdescr->save('more than 4000 chars');
...
This case:
I tried:
$sql = ("INSERT INTO table ( ctype ) VALUES ( custom_type(EMPTY_CLOB()) ) RETURNING ctype.c_clob INTO :clob");
$stid = oci_parse($conn, $sql);
$clobdescr = oci_new_descriptor($conn, OCI_DTYPE_LOB);
oci_bind_by_name($stid, ':clob', $clobdescr, -1, OCI_B_CLOB);
oci_execute($stid);
$clobdescr->save('more than 4000 chars');
ORA says: "ORA-00904: CTYPE.C_CLOB: invalid identifier";
How to?Or how to access with any solution?

How do I handle spaces in the path name of a file with PL/SQL? This is what I am trying to do.
start f:folder namefolder name with spacesfoldernamescript.sql
I keep getting an error:
"The file 'f:folder.sql' does not exist."
Is there a special character I need to put in there for the spaces? How can I get this to work?

I am trying to handle PK violation error on a certain table, on INSERT, my best guess is I should use a trigger. The basic idea is this:
The table consists of 7 columns, and 6 of them are PK, and the seventh one is "amount". I want to handle PK violation in such way that, if it occurs during INSERT, then instead of inserting a new row, it should just update the "amount".

the more customers we have for our software solution the more individual oracle objects (Tables, Packages, Functions, etc.) we have in our scheme. Right now we separate these by giving them identifying names like "X_CUSTOMER1_TABLENAME" e.g. (I know ..... )
This is not very practical when keeping our reference clean and when deploying/syncing our reference with a customer db: One customer would receive the objects of other customers on a deploy.
Is there a common solution to this problem? We were thinking about having a separate scheme for each customer. That way we would have our standard, untouched scheme with the basic functionality and the customer schemes with the individual content.
To make it a bit more concrete: We have around 100 basic tables that make the most of the content/functionality of the software. Each customer might have between 1 -5 additional tables with "custom" data that is used in conjunction with the standard objects in individual packages, functions etc. The installations will be made on our customers systems. So I have in mind to have schemes 0001, 0002, etc for each customer IN OUR REFERENCE. But we would then deploy only the scheme for that certain user when installing on their system. So for example for customer 0001 I would deploy the STANDARD and 0001 scheme
