View 2 Replies View RelatedWe are on oracle 10.2.0.4 on solaris 10. My question is on a sql query. Is it possible to rewrite a query to avoid the connect by and prior constructs and use joins? For example i have the following query:
SELECT empno,
ename,
job,
mgr,
hiredate
FROM emp
START WITH empno in (7566,7698)
CONNECT BY PRIOR empno = mgr
How can it be rewritten using a two table join (self join)? I am not sure if it can be done and whether it is possible.
I have a dynamic query that is ending up getting larger than 32k and this query is the base of a ref cursor that would in turn return the results to the application. How can I solve this problem since the largest content of a pl sql variable or literal is 32k ( said by oracle ) ?
PROCEDURE sp_large_query (c1 OUT sys_refcursor)
IS
BEGIN
OPEN c1 FOR ' SELECT STATEMENT WITH MORE THAN 32K ';
END;
high number of executions of specific types of queries which is using only rownum clause. For exam.
select ani, rowid from tbl_smschat_upuor where rownum<=:"SYS_B_0";
DB is having high number of executions of these type of queries and these when I m checking the execution plan for the same type of queries it is accessing the full table scan.
======================execution plan for above query
1000 rows selected.

Im going to create a trigger(insert or update) for a table A, when it fires inserted or updated columns are should be insert or update into another table say table B, one column(Processed_time) in table B where its value will be by subtracting two columns in table A(response_time,Submission_time) all are timestamp type.
How to update(Processed_time) in table B by subtracting above two columns in table A.
I need to print out all the triggers/procedures from an Oracle 9iForms. When I open an Oracle 9iform in the Oracle form builder, I click on FILE/CONVERT but cannot see the triggers/procedures.
View 2 Replies View RelatedTriggers for oracle database. What I am trying to do is copy original data from one table to another table prior to an update, insert, or delete occurring. Basically we are trying to keep a transactional history, with out having to restore the data. Here is what I have created to date, however it is not executing consistently.
CREATE OR REPLACE TRIGGER DATA_COPY BEFORE

We have three unix servers with four databases (10gR2) containing "HP Operation Management Unix" (OMU) server messages for monitoring purpose, and we now want to transfer these data to one new database on a new server for reporting purpose.
The message table in each OMU database keeps the message row until it is "Acknowledged" or for maximum fourteen days, then it is moved to an historic table where it stays for another three days. Keeping data for only seventeen days are a performance issue.The new "Reporting database" is intended to hold messages data for the last 90 days.
I wonder which method to use to move/replicate data against the databases? Materialized view using database link, with view on top of the MVs. How to keep rows longer than the master (source) table, avoiding deletion when master row is deleted
Oracle Streams, with local capture and remote apply. How will this influence on the master database performance. There are about 10000 new messages in each OMU database every day. Is it possible having four streams connections against the reporting database ?
Or should I simply use database triggers which fires after insert and update and applies changes to the reporting database using database links ?
For triggers, is it possible to do separate actions on insert , update and delete. For example, if insert is the case, do select; if update is the case, do select from another table and so on?
View 1 Replies View RelatedI am new to Oracle Workspace Manager. I have a trigger that fills my IDs every time i insert a record. I created the trigger before I enable the version of my table. After version was enabled in my table, I can no longer find my trigger but have these triggers instead:
OVM_DELETE_7 OVM_INSERT_7 OVM_UPDATE_7
What I wanted to do is Query the triggers that I created on my tables. Is there a way to do that without disabling the version on my table? I have too many version-enabled tables and that would be a hassle disabling the version in every table just for that query.
I need to do a PL/SQL program that prints the same that this WITH clause query, without using WITH or CONNECT BY, i was thinking about a solution with cursors?

I have the following table structure...............
Main_Head table name
main_head_id ,pk
head_desc,
head_id ,

the table is recursive table self join

now i want to write the query which return all head_desc which have same head_id
I have this SQL select to give me all the nodes of a tree starting at a particular node:
SELECT tree.node_id, LEVEL depth_level
FROM tree_of_nodes nodes
START WITH nodes.node_id = 1000
CONNECT BY PRIOR nodes.node_id = nodes.parent_id
I need to update a column called dept_level, which is essentially the same as Oracle's LEVEL. Something like this statement is what I need, but obviously this statement doesn't work:
update tree_of_nodes
set depth_level = LEVEL
START WITH nodes.node_id = 1000
CONNECT BY PRIOR nodes.node_id = nodes.parent_id
I've tried inline views and other approaches and have not found a method that works.
We have an requirement to create xml data for entire database (selected tables) which are in hierarchy.Procedure should read node_mapping table having parent and child tables relationship info and build XML Select statement.
Currently it is building SQL statement whenthere are one parent having multiple childrens i.e Dept having emp, emp_act, emp_rsch..but when child node are having childrens then it is not working - it has to repeatedly call this procedure (recursive) and build below given SQL statement.
1. To change procedure to build xml sql statement when there are multiple childrens to child nodes (hierarchy)
2. To format the output in xml data
We are using ORACLE 11G and WINDOWS 7
CREATE TABLE node_mapping
(
NODE_ID NUMBER(5) PRIMARY KEY,
PARENT_NODE VARCHAR2(100),
CHILD_NODE VARCHAR2(100),
PARENT_NODEID VARCHAR2(50),
CHILD_NODEID VARCHAR2(50)

I need to use Recursive Subquery Factoring for a project of mine, specifically I need to use some code I have found in a function.
[URL]
The code I have so far is this:
create or replace
function recursive
(
pattern in raw
, solution in raw
) return number as
[code]....
But when trying to compile it in Oracle SQL Developer, I get the following two errors:
Error(9,1): PL/SQL: SQL Statement ignored
Error(10,30): PL/SQL: ORA-00907: missing right parenthesis
The errors refer to these two lines:
with x( s, ind ) as
( select sud, instr( sud, '' '' )
I have looked over and over the code again, and I do not see any missing parenthesis. Furthermore I tried using with in a smaller test function:
create or replace function test
(
p in number
)
return number as
v number;
begin
with t(a) as
[code]....
Which compiles just fine, so I'm not sure why that line is being ignored in this function. The whole idea here is to replace the sudoku string in the function with a variable that I built from the two parameters.
I am using Oracle 10g Database as back end and Developer 6i as front end.I have a procedure which is called upon SAVE. Means before COMMIT;This procedure holds few updates and delete statments.
This prcedure is throughing sql error as follows: ORA-00604: error occurred at recursive SQL level
The error occur when an delete statment is issued which as follows: DELETE FROM DUMMY_TAB001;
I issue the same statement from SQL it is running fine. But when my from runs on this delete statment encounter it through the above oracle error ORA-00604.

In MS Windows, if I copy a file and paste it into the same folder, I get a copy with the text 'Copy of' in front of the file name. If I paste it again, I get another copy with a different version number.
E.g.
sqlnet.log
Copy of sqlnet.log
Copy (1) of sqlnet.log
Copy (2) of sqlnet.log
I was wondering if I could copy existing rows into a table and do the same thing?
So, for example if I had this table:
create table tst_srch (srch_is varchar(100), user_name varchar(100), srch_name varchar(100));
insert into tst_srch values (1,'USER1','SRCHA');
insert into tst_srch values (2,'USER1','SRCHB');
insert into tst_srch values (3,'USER1','SRCHC');
insert into tst_srch values (4,'USER1','SRCHD');
insert into tst_srch values (5,'USER2','SRCHC');
insert into tst_srch values (6,'USER2','SRCHD');
insert into tst_srch values (7,'USER2','SRCHD_1');
Could I write a procedure like copy_searches('USER1','USER2') that would copy all USER1's searches to USER2 - including renaming any duplicates.
So it would create these new rows:
8,USER2,SRCHA
9,USER2,SRCHB
10,USER2,SRCHC_1
11,USER2,SRCHD_2
I've looked at various insert statements, merge and match statements and exception handling in procedures .
I have a table:
create table FIELDS
(
FIELD_NAME VARCHAR2(30) not null,
PRG_FIELD NUMBER not null,
LENGTH NUMBER
);
with
INSERT INTO FIELDS VALUES('FIELD1', 1, 3);
INSERT INTO FIELDS VALUES('FIELD2', 2, 3);
INSERT INTO FIELDS VALUES('FIELD3', 3, 4);
INSERT INTO FIELDS VALUES('FIELD4', 4, 2);
INSERT INTO FIELDS VALUES('FIELD5', 5, 1);
I need to insert in a table:
create table STUFF
(
FIELD_NAME VARCHAR2(30) not null,
FSTART NUMBER not null,
LENGTH NUMBER
);
And the output I want is:
INSERT INTO STUFF VALUES('FIELD1',0,3);
INSERT INTO STUFF VALUES('FIELD2',3,3);
INSERT INTO STUFF VALUES('FIELD3',6,4);
INSERT INTO STUFF VALUES('FIELD4',10,2);
INSERT INTO STUFF VALUES('FIELD5',12,1);
So each field starts where the previous (ordered by PRG_FIELD asc) ends.
I think the query should use both lag and connect by but I haven't had any luck writing it. The problem is that all the examples I've seen around, using connect by prior, utilize 2 fields with different names, es connect by prior emp_id = mgr_id. Instead I should do something like connect by prior prg_field = prg_field-1 but that doesn't seem to work.
PS: I don't necessarily need to do this, I have a guy manually writing the inserts, this is just an exercise I would like to figure out
Ive just tried running a simple
update BASIC set 'column name' = NULL
Which works fine if i specify a where clause that returns a low amount of values, but im trying to run this update for the whole column (1000's or records).
Ive had no experience of this error before and am unsure of where to start, ive had a quick read around but see something of removing triggers?
The full error is :
ORA-00036: maximum number of recursive SQL levels (50) exceeded
ORA-06512: at "new.su_Table", line 61
I'm trying to drop a user but it gives me below error message-

However when i check from dba_queue_tables or user_queue_tables it doest show any queue tables.
Oracle Version :- 11.2.0.2 I found a error in a trigger(Statement Level) ORA-00604:error occurred at recursive SQL level string. Before Finding this issue,Once the DB Response was slow . Will this be the issue Of DB Slow response. The Above trigger fires for each entry in an transaction table. The code is Patched and was executed . The above issue was found during another issue and not the DB Slow response. My Doubt is Whether DB response slow issue would be because of this. Now after fixing this Slow response was not reported.

i have a trigger as below
create or replace trigger INS_ERRORS
before insert on MIG_STG_ERRORS
for each ROW
declare
V VARCHAR2(22);
[code]........
when i insert into MIG_STG_ERRORS getting error message like 00036. 00000 - "maximum number of recursive SQL levels (%s) exceeded"
*Cause: An attempt was made to go more than the specified number of recursive SQL levels.
*Action: Remove the recursive SQL, possibly a recursive trigger.
I am working on the quality center oracle database to write a query that fetches all steps of a test case including the ones having calls to tests. Structure of table is explained below. I've made up an example and attached it as an image to this post. This image also has the expected result of the query I want to write.
Table Name: STEPS (This table contains steps belonging to tests. Some steps are simply calls/links to other tests)
Columns:
STEP_ID (primary key - integer)
STEP_NAME (char)
STEP_DESC (char)
ORDER (integer)
TEST_ID (reference to table TEST.test_id)
[code].......
Referring to the example (see attached image), I'm looking to write a query that gives me all steps (including steps from called tests) of the test - "Empty trash from mailbox" in the correct order.
To start with I can write the following query to get steps of the test - "Empty trash from mailbox".
SELECT * FROM steps WHERE test_id = (SELECT test_id FROM test WHERE test_name = 'Empty trash from mailbox')
When trying deploy an mapping, the database link get this error:
ORA-06550: PACKAGE BODY, line 0, column 0:
ORA-04052: error occurred when looking up remote object db1.someC@db1@LOC_db
ORA-00604: error occurred at recursive SQL level 1
ORA-12170: TNS:Connect timeout occurred
I can use tnsping towards the db. I can use
elect * from v$instance@db1@loc_db

What is the purpose and use of 'Instead of Triggers'
View 20 Replies View RelatedI have to write two triggers on same table for auditing different columns of different users(may be different modules).
I will have an audit table in which i will insert data such as (user_id,module_id,column_name,old_col_val,new_col_val,timestamp)
Now different users from different modules will update the data on same table may be same columns from different front end forms!
If we write directly, we will not be able to know which column is updated by which user.
My question is in this case how can we control the triggers to raise differently?
I have rather large compound triggers that I discovered were not firing this morning, so I created a simpler compound trigger to test:
CODECREATE OR REPLACE TRIGGER "test"
FOR INSERT OR DELETE OR UPDATE OF KI_NM ON CHEMAXON.CB1ASSAYS
REFERENCING OLD AS OLD NEW AS NEW
FOR EACH ROW
ENABLE
[code]...
It's just not firing. The tables are all in the owner's schema (who has DBA rights). My Google-fu is failing me, and I'm not sure how to start troubleshooting general trigger failure.
