SQL & PL/SQL :: Handling Exceptions Without Halting Execution
Sep 14, 2010
I have a set of 500 insert queries which i need to execute. I have included exception handler to catch any errors encountered. I don't want the execution to halt when an exception is encountered, i want the next insert statement to be executed
For the following procedure if I send the existed employee number of emp table as input. The procedure is executing successfully. But if I send the employee number as input which does not exist in the emp table . The execution block does not handling the exception.
I am getting the following error.
ORA-06502: PL/SQL: numeric or value error ORA-06512: at "RAKULA.SP_TEST_EXCEPTION_BULK", line 8 ORA-06512: at line 7
If I use WHEN OTHERS exception then I am able to handle that exception. Why it's happening like this.
CREATE OR REPLACE PROCEDURE RAKULA.sp_test_exception_bulk(i_empno NUMBER) IS t type_test1; BEGIN SELECT deptno BULK COLLECT INTO t FROM emp WHERE empno=i_empno; [code].......
how to handle that exception.
If I create the procedure without using
BULK COLLECT then I am able to handle that exception using WHEN NO_DATA_FOUND
In the following procedure I am able to handle the exception.
CREATE OR REPLACE PROCEDURE RAKULA.sp_test_exception(i_empno NUMBER,v_dept_no OUT NUMBER) IS BEGIN SELECT deptno INTO v_dept_no FROM emp WHERE empno=i_empno; EXCEPTION WHEN NO_DATA_FOUND THEN dbms_output.put_line('employee number' ||i_empno|| 'does not exist'); END sp_test_exception; /
------------------------------------------------------------------------------------------------------- While Condition LOOP BEGIN Insert into table1 values(......);
[Code]...
EXCEPTION When OTHERS THEN <capture the error while inserting into an Error table> END; END LOOP; -------------------------------------------------------------------------------------------------------
Now I want that If one of the insert statement within the loop fails (say table2) the exception should be captured and next insert statement (table3) should be executed.
How can I do this ? I guess I wont even need a loop
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
java.sql.SQLException: Unexpected exception while enlisting XAConnection java.sql.SQLException: XA error: XAResource.XAER_RMERR start() failed on resource 'weblogic.jdbc.jta.DataSource': XAER_RMERR : A resource manager error has occured in the transaction branch javax.transaction.xa.XAException: Unexpected error during start for XAResource 'EOD': null at weblogic.jdbc.wrapper.XA.createException(XA.java:103) at weblogic.jdbc.jta.DataSource.start(DataSource.java:765) at weblogic.transaction.internal.XAServerResourceInfo.start(XAServerResourceInfo.java:1182) at weblogic.transaction.internal.XAServerResourceInfo.xaStart(XAServerResourceInfo.java:1115)
Is it possible to insert a table in case of exceptions. For example, i have a function like this:
Create or replace Function test_function(p_Parameter_ID number) Return number is
l_Variable number; Begin Select output into l_Variable from test_table where id=p_Parameter_ID; Exception when others then Insert into exception_Table values('No Data Found', p_Parameter_ID); return l_Variable; End test_function;
In this function, if you notice, i wanted to populate an exception table for further analysis in case data is not found. The function gets compiled without any error in this case.However when i execute this and the Select query does not return any output for a particular parameter_ID, then the exception part fails. It gives me an error "cannot perform a DML operation inside a query".
Can't i write insert statements inside the exception section?
Why exceptions does not raise in cursors declared by user like in the following program
create or replace function sal (p_id employees.department_id%Type) return number is ----sal1 employees.salary%type:=0; cursor cx is select * from employees where department_id=p_id; begin for i in cx
how to put exceptions while defining the summary item ? In one of my datablock there are certain lines whose "inactive_flag" gets a "Y" value on certain events. I want my summary item to exclude such amounts from summing up.
create or replace procedure except_handle is v_errorcode VARCHAR2(10); v_errormsg varchar2(200); constr_violation Exception; PRAGMA Exception_Init(constr_violation,-2292); [code]..........
Here, I have assigned values to the variables 'v_errorcode' and 'v_errormsg' directly inside the exception block so that I can use them in both exception types 'constr_violation' and 'others'. I am getting an error message like,
Error(22,1): PLS-00103: Encountered the symbol "V_ERRORCODE" when expecting one of the following: pragma when
how to define user defined exceptions for cases like, ==> when anyone tries to insert string values without using single quotation marks " '...' "? ==> update the column which is not present in table.
how can I define user defined exceptions for such cases?
I have 2 tables, AFF_TEMP and COUNTY AFF_TEMP has the following columns FNAME, LNAME, EMAIL and COUNTY COUNTY has 2 columns COUNTY_ID and CNAME
Both tables have the following test data AFF_TEMP Joe, Bloggs, joe@gmail.com, '' Ann, Bloggs, anne@gmail.com,Donegal
and COUNTY column in AFF_TEMP can contain a NULL value
County table has the following Test data, 1, Dublin 2, Donegal 3, Tipperary, 4, Galway
I am trying to select the following from both tables FNAME, LNAME, EMAIL, COUNTY_ID.Tried the following queries select a.FNAME, a.LNAME,a.EMAIL, C.COUNTY_ID FROM temp_aff A LEFT OUTER JOIN COUNTY C ON A.COUNTY=C.CNAME OR (A.COUNTY IS NULL) select a.FNAME, a.LNAME,a.EMAIL, C.COUNTY_ID FROM temp_aff A, COUNTY C WHERE C.CNAME IN (SELECT UPPER(A.COUNTY) FROM TEMP_AFF A)
I am using for writing text files data to database. The problem here is let us assume there are 6 records in text file and if there is a problem at 2nd record, the later records are not getting inserted.
CREATE OR REPLACE PROCEDURE PROC1 IS temp varchar2(500); tmp_name varchar2(5); tmp_no varchar2(4); . BEGIN WHILE NOT end_of_file LOOP
IF i = 18 THEN tmp_no := temp; END IF;
IF i = 21 THEN tmp_name := temp; END IF;
END LOOP; END; /If i=18 and temp = '12345' here, then tmp_no := temp; won't work (tmp_no varchar2(4);) Similarly, If i=21 and temp = 'ABCDEFG' here, then tmp_name := temp; won't work (tmp_name varchar2(5));
how to handle this through EXCEPTIONS so that even if there is a problem with 1 record, while loop remain working for further records..
I'd like to achieve the following (and YES, I do know that this is not multi-user safe, but that's not the point here):
Before inserting a record, the trigger shall check if there's already a duplicate one. Duplicate means in this case when there is an intersection of the time frame, defined by two numeric timestamps. That's also the cause why I cannot use a simple UNIQUE constraint here (in my opinion).
Okay, that already works (see code below). But now I need colliding records to be written to a temporary table so that those records can be returned and presented to the user for selection.

Basically I've created a function, when I run it there is a user input. Mine is a customer number between 1-10.
I was wondering is there a way to add in error check so if I typed in an invalid number it would give me a message saying "Wrong customer_number" or something along the lines of that?
I was told I wasn't able to use "DBMS_OUTPUT.PUT_LINE" in the function I need to tamper with the function header?
Here is my header -
CREATE OR REPLACE FUNCTION hours (custid customer.cust_id%TYPE)
I am writing a after trigger for one of my tables on every insert update and delete for my dataware house staging area. The process here is when ever there is a change in the production database we need to capture this change in our changing area through triggers.
I am able to create the triggers but i am stuck with the exception handling portion of the trigger. I want to write an exception in the trigger where when the staging area is locked or for any other matter the data needs to be able to go to a error table when the staging area is not able to accept the data for some reason.
how i can write this excepyion in the trigger or anyother method i can follow to be able to handle this scenerio.
I am writing a cursor and inside that cursor I am checking record exists or not and based on that I am doing my operation.But I am getting error that i can not use exception inside cursor see the below sample code (syntax may not be correct)
sample code------------------ cur c1 is select * from T1; open c1 loop fetch c1 into cur_id;
select name into var_name from t2 where id = cur_id;
exception when no_data_found then continue with next cursor value end
update t3 set name = var_name where t3.id = cur_id; commit; end loop; end;
I'm attempting to write a plsql for finding missing archived logs for streams.
requirement is to run a select statement and print 1. 'NOT FOUND' if name column is null 2. '<name of the files>' if rows are returned 3. 'NOT FOUND' if no rows are selected. (here is were i'm having trouble)
code i developed so for: for cr in (select decode(name, NULL, 'NOT FOUND', name) from v$archived_log where deleted='YES' and status!='A') loop if (cr.name = 'NOT FOUND')
I am trying to convert this into a relational DB view.

How to handle special charater '&' in stored procedure.
Following is a test code I want to Implement
CREATE OR REPLACE PROCEDURE SP_Test(QueryID NUMBER,DateFirst DATE,DateLast DATE) IS BEGIN INSERT INTO TempTable(QueryID,LineID,data,Datetime) SELECT 1,6,Emp,startdate FROM salary
[code]....
The code above resuts into INVALID state of stored procedure and cannot be executed.
We have database with multiple fields containing NULL values and in many queries we have NVL function which in turn is suppressing the index usage when in fact it is really essential (selectying very few rows from massive data) instead of creating lot of Function based indexes (NVL) or composite indexes with (nullable_column, constant) I am thinking of settting a default value for most of the fields In that regard I have some queries :
Which approach is better - setting default value for the fields or updating the fields with default value and modyfing inserts to take care of future data? Though altering table and modifing column to set default value looks better considering it will take care of data inserted in the future, it will invalidate the subroutines.I understand in 10g both statement will generate lot of undo (though in 11g, I heard things changed for setting default value of a column) How to take care of all the queries which are using the criteria 'where column1 IS NULL' or 'where column1 IS NOT NULL'. It will be really difficult task to manually change each and every occurrence of such condition even using user_source.
Finally for numeric values say for ID field which starts from 1 onwards 2,3,4 etc, we can set 0 as sensible default so that the performance is not affected.
Is there such precaution for varchar2 field purely from performance point of view?
i get flat file and i have set up a control M job so that it runs at a particular time.
initially my control file was as below:
LOAD DATA INFILE 'DFILEabcd.dat' BADFILE 'BDabcd.bad' REPLACE INTO TABLE abcd_table (A position(01:09) CHAR, B position(11:12) CHAR, C position(14:33) CHAR, D position(37:50) char)
this was working fine. control M did not send FAIL message.but later i had to change the ctl file due to requirement. i had to add a when clause.
my code after modification is:
INFILE 'DFILEabcd.dat' BADFILE 'BDabcd.bad' REPLACE INTO TABLE abcd_table when A<>'10' (A position(01:09) CHAR, B position(11:12) CHAR, C position(14:33) CHAR, D position(37:50)
now the control M is sending an erro message after it runs the job. error is Return 5. thats all it gives.
i think it is due to errorlevel 1. in log file it says zero records inserted due to data error. then what is causing control M to send fail message??
sqlloader is loading all the required records correctly.
