SQL & PL/SQL :: How To Handle Exception And Continue Process
Aug 24, 2012
I am trying to execute the below package. While executing i face a problem where when NO DATA FOUND the excpetion is handled and coming out of the loop.but i want to to continue the loop after handling the exception.
Is there anyway i can modify the code
CREATE OR replace PACKAGE BODY pkg_purge_archive_check
AS
PROCEDURE Purge_archive_tables_check (purgerows IN NUMBER)
IS
v_num_1 NUMBER(10);
v_num_2 NUMBER(10);
v_multiplier NUMBER(10);
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].........
I trying to Assign XML content to the clob variable inside the pl/sql block, But i am getting the Below Error:
declare t clob; begin t := 'xml content exceeds 32000 characters'
update test clob_cloumn = t; where id =2;
exception when others then null; End;
ORA-06550: line 5, column 4: PLS-00172: string literal too long
I need to handle this exception, i know it length exceeds 32000 characters, but even though i need to handle the exception and to perform other operation after handling the exception.
In my application, we are getting the following exception on calling the Java procedure.
java.sql.SQLException: ORA-29532: Java call terminated by uncaught Java exception: java.lang.OutOfMemoryError ORA-04030: out of process memory when trying to allocate 10804020 bytes (joxp heap,f:OldSpace)
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 BEGIN Block of the code where a loop is running .I also have a CONTINUE statement in the EXCEPTION Block of the code where I return the control to the BEGIN Block in case of any exception.Now as per ORACLE Company, CONTINUE has a old issue which is already registered by Oracle Company Bug 7306422.
The issue is where CONTINUE statement does not run properly when your code Optimization level is 2. However it will work properly if we have the Optimization Level as 0 and 1.are facing the same issue here and have a workaround.
Is there any code which I can permanently use instead of CONTINUE but have the same logic incorporated.i.e returning to the next iteration whenever I say to pass the control.
function test_1 begin if....then ...end SELECT... BULK COLLECT INTO.. FROM .... [code]...
obviously this is not the whole code, but lets say the first if...then..end is true , does this mean it will exit the block? like it won't continue to the other stuff like select, if ...then statements?
i've a problem regarding my code at line: 76. URL....
If i put a RAISE_APPLICATION_ERROR just before: SELECT ID_GIOCATORE INTO CONTR_GIOCATORE2 FROM COMP_CONTR_GIOCATORE_PARTITA GC JOIN CONTRATTO C ON GC.ID_CONTRATTO = C.ID_CONTRATTO WHERE GC.ID_PARTITA = :NEW.ID_PARTITA AND (C.ID_CASELLA = 28 OR C.ID_CASELLA = 12) AND C.ID_CASELLA <> :NEW.ID_CASELLA AND [code]....
But if i put the RAISE_APPLICATION_ERROR just after this statement and before IF(CONTR_GIOCATORE2 IS NOT NULL AND CONTR_GIOCATORE2 = CONTR_GIOCATORE) THEN, nothing happens after the insert(that goes well) and the trigger doesn't do his job(insert,update etc). if i do that select, i got the no data found, so i put the exception to set the variable CONTR_GIOCATORE2 to NULL.
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.
1.Header(Contains the File Name,Branch Name,MIS date) 2.Body(Customer Details) 3.Footer (File Name,Contians Total Number of Records and Number of Customers)
from the above code I want to execute both the inner block exception and outer block exception and is there any way to pl/sql engine that execute the outer exception first and inner next
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?
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:
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";
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".
declare type osd_refone is ref cursor; osd_ref osd_refone; l_status number; [code]......
abc_reports in this pack "ab_report" it is the function it having the ref cursor as out parameter . when am executing the above anonymous block am getting the below error,so how can i print the out ref cursor data in my block.
ERROR at line 8: ORA-06550: line 8, column 12: PLS-00221: 'OSD_REF' is not a procedure or is undefined ORA-06550: line 8, column 3: PL/SQL: Statement ignored
