ID, DECRIPTION and HOX, are nullable columns.When inserted ID on table, description will automatically updated by the trigger as 'NOT VALID', now I need modification on the trigger that if the IDchanges from 1000, (the HOX-value stays at it was) to some other value like 1001 description willupdated to 'VALID'. But if the ID is not 1000, like 999,description will stay as NOT VALID.
I have 2 questions, because they can be inter-related I am posting it in a single post. These queries are related to Oracle(PLSQL).
1. I am trying to increase the size of a field in a table which has almost 2 million records and the query for alteration runs for almost and hour and rollsback, wondering is there a better way of doing it.
2. I have modified the size of a field in a table from Varchar2(10) to Varchar2(20), now when I tried to rollback the modification it is not letting me to change the size from Varchar2(20) to Varchar2(10). No data has been inserted after the modification.
How can I modify the check constraint without dropping the already existing check constraint.
Example: alter table table_1 add constraint const_chk check (ATTRIBUTE7 in ('READ','UNREAD');
Want to add some TENTATIVE value for the already existing one. I could do that by dropping the constraint
ALTER TABLE table_1 DROP CONSTRAINT const_chk and modifying it later as alter table table_1 add constraint const_chk check (ATTRIBUTE7 in ('READ','UNREAD','TENTATIVE');
Is it possible to do that with out dropping the constraint?
Need to change the precision of a column in a existing table. Statistics about the table
* has over 130 columns * More than 300 million records * Column to modify is #121 which has data * No primary key defined
Since the column has data, it is not possible to modify with a simple Alter.
Second option - create temp column in same table, update from original, put null in original, alter, update back from temp, drop the temp column. This approach is very expensive and time consuming.
I want to replicate single table data/modification from source db to destination DB.procedure or steps how to create replication between source and dest db for single table.
CREATE TABLE TEST ( EMPNO NUMBER, SAL NUMBER ) / CREATE TABLE SUMSAL (
[code].....
Say I have emp table. Now what I want is that whenever I enter new records in EMP table, I want to sum up the value inserted for SAL column and I want to do some task based on that value.
I'm inserting the EMPNO and SAL in test table whenever a row is inserted in EMP table. Now from there I want the SUM(SAL) column. As you can see I took the sum and inserted it into another table (or I can update a packaged variable with this value). It is inserting as many rows in SUMSAL table as many I insert in emp table through Oracle Forms. I want it to insert only one row in SUMSAL table because after user enters all the data for EMP table, I want to capture the sum of Salary inserted and then I want to perform some tasks based on that value.
SQL> select * from test 2 / EMPNO SAL ---------- ---------- 1111 100 2222 200 SQL> select * from sumsal
[code].....
-- Here it should be only one value. i.e: Sum(SAL) column. That is 300. But whatever task I want to perform it performs it for each row inserted. But I want to perform it after trigger inserts all the rows in TEST table.
I wrote an after insert trigger at table level but still I'm getting the same result.
We have created instead of triggers on view.When ever we drop the view and recreate .It drop the triggers as well.Is there a way to preserver the trigger.. so that we can drop the view and trigger will not get dropped.
I am trying to use execute immediate in a trigger. See the below example
create table test_tbl(col1 number,col2 varchar2(10), col3 date); create table test_tbl_log as select * from test_tbl where 1 = 2;
create or replace trigger test_trig after insert or update or delete on test_tbl for each row declare v_str varchar2(4000); [code].......
insert into test_tbl values(3,'test',sysdate);
I got the Error : -1008->ORA-01008: not all variables bound
In the execute immediate statement if I change the v_using_str variable to :new.col1,:new.col2,:new.col3 trigger is running fine. But here I have to create trigger on all the tables in my schema and I dont want to list all the column names for each table manually and I am using a for loop to build the v_using_str string in my original code.
There is a Table, on that table there are 2 triggers are written 1) row level trigger 2) statement level trigger. Now i am inserting one row into that table, so which trigger will be fired first and why?
I have created a trigger for after insert which updates a table when there is a row inserted in that table. The update is on a column which stores the application description along with the sequence number. Now my requirement is that sequence number should be unique only with in an application but not with in the table.Say the row entry can be as follows:
App_Desc Request_ID ----------------------- DEV 100 1 DEV 101 2 STG 100 3 STG 101 4
Here Request_ID is unique But the sequqnce thats created for DEV (100,101) should take an entry of 102 for the next entry for DEV and same applies for STG. So I have to use the same sequqnce for all the application.
CREATE OR REPLACE TRIGGER PPMAPP.PPMCR_HH_CHR_TRG AFTER UPDATE ON PPMCR_STEN.PPMCR_HH_CHARACTERISTICS
[code].....
The cursor HH_ATTR_CSR returns a set of values and I'm iterating each values using a loop, but when comparing the post and pre values, I have to use the variable(HH_ATT_VAR) instead of column names.Usually we give it as (re.XXXX_YYYY) but the cloumn names has to be given in the form of a variable got from the cursor like (re.HH_ATT_VAR).In doing so, I'm getting an error as "bad bind variable" So,Is there any to view the old and the new value in the local?

I have created a link of *.mdb (Microsoft Access File) with oracle 9i database with ODBC connectivity.
Problem is i can not track any changes made in *.mdb file table. Is their any option to track any changes like insertion, updation or deletion made in *.mdb file table.
the index_id and time_vertex_id will be unique and when the date is 17th i.e the first date will be inserted the current rate will be 4.7 and the previous rate will be blank and when another date is inserted i.e 16th the previous rate of 17th will be the current rate of 16th i.e 6.4.
when 14th is being inserted, the previous rate of 16th will be the current rate of 14th i.e 7.4 and if after 14th is being inserted, 15th is being inserted, then the previous rate of 16th should be updated as per the current rate of 15 say 8.5.
I have one table with one row with some coefficients. If I update a coefficient from my table I want to be updated all the rows from another table. I've made a trigger but in the second table I have a column for example TOTAL and I want that column to be multiplied with my new coefficient, and I want this for every row in the second table. How I can select that total column in the trigger for every single row and update it?
how to create the trigger that count the last 7 day about from sale table if the last 7 day amount is greater then 10000 then update the commission 2% other wise do nothing
I have a trigger "before update" that change some values, including a timestamp column. My sql code does an update using the "returning clause" to get the values changed by the trigger. The problem is:
When I do an "update [...] returning timestamp_field", this timestamp_field has the old value equals to null (in the trigger). And, this field in the table is not null. This problem not occurs with the others fields of type number, varchar... only with the timestamp field.
Here are the code to simulate this problem:
--Table create table TB_TEST ( ID NUMBER(10) not null, FLAG NUMBER(10) not null, TAG VARCHAR2(16) not null, TS_ATU_DTR TIMESTAMP(9) not null );
"old.TS_ATU_DTR=, " Isn't it right????? Why the other fields aren't null? I need the "old.TS_ATU_DTR" to use in my other trigger to compare timestamps, how can I get it?
The below trigger is running fine without any error ,but i wasn't able to perform the exact logic by the below trigger.IF, inserting multiple row then the SIVNUM field gets the same sequence number for each row , without incrementing the value for the next row.
Only the sequence value increases on the next set of row ow's inserted
Example (inserting 2 rows ) based on the below trigger:

I used two tables in my procedure..TBLEMP and TBLORG..
STEP I :-> I try to insert record in both table TBLEMP and TBLORG...I written seperate BEGIN and END block for TBLEMP and TBLORG Insert operation...When some exception is occured then I rollback all the data..if not then insert statements are commited..
STEP II :-> On table TBLORG one trigger is written..that will execute on each new insert...In this trigger I get the current record(Current employee) data from TBLEMP
Now my question is for executing trigger is it necessary to commit the TBLEMP operation, before getting data from TBLEMP.
