PL/SQL :: Trigger To Insert In One Table From Other And Truncate 2nd Table
Aug 2, 2012
I have table t1 and t1 , I want a procedure that will insert all records from t1 into table t2 and after successfull insert table t1 should be truncated .
If their is any problem in insert in to table t2 , the truncate command should not work .
Truncate command should work only after successfully insert command .
writing a trigger body. My requirement is i need to insert a new record in a task table when ever a new record is inserted into employee table.Here in the trigger i need to select the name of the employee in the last inserted row in employee table and insert the name in task table.I tried to write the code as below
insert into task(name, date, type) values ((select name from employee where emp_id=(select max(emp_id) from employee), sysdate, 'document'));
When i am trying to insert record using trigger, it is taking last but one record from the employee table.
In the trigger I am calling a procedure that returns an error if there is any error returned from procedure. I have to update the table table1's column error_desc (for the same new inserted record for which the trigger was called) with the error received by OUT parameter of procedure called in trigger. I have to update the same record on whose insert this trigger was called.
I have three tables. One for projects, one for volunteers, and a bridge entity for the many to many relationship between the Project and Volunteer.
In Project table, I have a field called, Volunteers_currently_signed_up, which means the number of volunteers currently signed up to participate in a project.
When I add an entry to my bridge entity which is composed of Volunteer_ID and Project_ID, I want the Volunteers_currently_signed_up to increment by 1, where the Project_ID in the bridge entity corresponds to that in Project.
I have very very little PL/SQL, and this is my amateur attempt so far:
CREATE OR REPLACE trigger "BI_Volunteers_currently_signed_up" BEFORE INSERT OR UPDATE ON Volunteers_in_project for each row WHERE Volunteers_in_project.Project_ID=Project.Project_ID; begin Project.Volunteers_currently_signed_up += 1; end; /
We would like to create functions to insert and update our tables and would like to make it not possible to update and insert the table directly outside of the function. Is there a way to do that in the trigger?
In a trigger(on update of a table t1) I am trying to write, I am doing an insert on t2 accessing ':new' values of the update on t1.
But in my Insert statement, I am having get one of the column values from another table. How can I write my insert statement in such a way as to insert values contained in ':new' pseudo columns and a select from another table. Below is my insert statement in the trigger : -------
IF (:old.GROUP_YELLOW <> :new.GROUP_YELLOW) THEN INSERT INTO TEST.W_THRESHOLD_LOG (THRESHOLD_LOG_WID, CHANGE_DATE, MEASURE_TYPE_WID, MEASURE_NAME, CUSTOMER_WID, CUSTOMER_NAME, USER_ID, CHANGED_ITEM, PREV_VALUE, NEW_VALUE) VALUES(TEST.W_THRESHOLD_LOG_SEQ.NEXTVAL, SYSDATE, :new.MEASURE_TYPE_WID, 'Rolling Stabilty' , :new.CUSTOMER_WID, 'Customer1', 'User1', 'GROUP_YELLOW', :old.GROUP_YELLOW , :new.GROUP_YELLOW); END IF; -------
In the above code if the hardcoded value 'Customer1' need to be picked from another table, i.e .
SELECT NAME FROM W_CUSTOMER_DIM WHERE CUSTOMER_WID = THRESHOLD.CUSTOMER_WID
how can I rewrite my query to the above value from the select into my insert statement..?
I have a table that has 2 columns of type nested table. Now in the purge process, when I try to truncate or drop a partition from this table, I get error that I can't do this (because table has nested tables). how I will be able to truncate/drop partition from this table? IF I change column types from nested table to varray type, will it work?
Also, is there any short method of moving existing data from a nested table column to a varray column (having same fields as nested table)?
I know this is an old thread and I just started working with triggers. I want to check if the data being inserted is already in the table and if not insert it:
create or replace trigger t_triggername before insert on tbl_tablename for each row begin if(:new.user_id <> :old.user_id) then insert into tbl_tablename(user_id, location) values (:new.user_id, :new.location); end if; end;
what if I wanted to keep the user but only update location if the user is already in the table. I've tried doing it this way:
create or replace trigger t_triggername before insert on tbl_tablename for each row begin if(:new.user_id <> :old.user_id) then insert into tbl_tablename(user_id, location)
I have a base table (Table A) block with multiple records displayed. I need to track audits to this underlying table in the following way:
If user updates a field in the block I want the pre-changed record's audit fields to be set and I need to create a copy of the record with the changed values. Basically any changes will result in the record being logically deleted, and a copy record created with the newly changed values.
Tried to implement in the block's pre-update trigger which will call a package to directly update Table A then Insert into Table A, then requery the block. Is there a clean and efficient way to do this?
The Scenario is that we have Master and detail table (With Foreign key enabled), we want to TRUNCATE Master table.
1) Is there any option which can Truncate the table without disabling the constraints for child tables...we want to Truncate the table forcefully.. 2) What will be best method to truncate a Table having Master detail relation (Foreign key enabled) and we need to truncate the table without disabling the constraint ( if there are records in child table) 3) What will be best method to truncate a Table having Master detail relation (Foreign key enabled) and we need to truncate the table without disabling the constraint ( if there are NO records in child table
i want to create a trigger that will update a table when there is an insert or update.i can't across this error that i don't even know what it means "table %s.%s is mutating, trigger/function may not see it".
*Cause: A trigger (or a user defined plsql function that is referenced in this statement) attempted to look at (or modify) a table that was in the middle of being modified by the statement which fired it.
*Action: Rewrite the trigger (or function) so it does not read that table.
CREATE OR REPLACE TRIGGER set_date_end BEFORE INSERT OR UPDATE OF issued ON shares_amount FOR EACH ROW DECLARE BEGIN INSERT INTO shares_amount(date_end) VALUES(SYSDATE); END set_date_end; /
I am trying to Truncate the table but it doesnt get truncated. When I issue the command it even doesnt throw the error. I also tried to drop the table but cant even able to drop the table. I thought table might be locked. But it allows me delete a row from the table.
I couldn't either DROP or TRUNCATE the table partitions that were created. Here are the DDLs and DMLs I'm using.
Create table student(no number(2),name varchar(2)) partition by range(no) (partition p1 values less than(10), partition p2 values less than(20), partition p3 values less than(30),partition p4 values less than(40)); Insert into student values(1,'a'); Insert into student values(11,'b'); Insert into student values(21,'c'); Insert into student values(31,'d');
When I do the following query, it returns data.
SELECT * FROM STUDENT PARTITION(p1);
But, when I try to perform any of the following queries, it says invalid partition name.
ALTER TABLE STUDENT DROP PARTITION p4; ALTER TABLE STUDENT TRUNCATE PARTITION p3;
I am using Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit
Our client has this scenario:May 23th 4:00 PM a user truncate a critical table. The customer need to recover the data before truncate.
The recover materials list like this: 1. A cold backup of this database at May 1th. 2. The archive log except May 1th ~ May 15th. 3. Every day exp at 00:30 and 12:00.
Is there any way to recover the data before truncate table with these material?
Are there redo generate during truncate operation even my primary database is in FORCE LOGGGING mode? How this will effect on physical standby database.
My requirement is to to truncate the table and load it with the data present in file. In the control file, I used the "TRUNCATE" command as well.In case, if the file has some invalid data and sqlldr fails, my existing data will be lost. Is there any option in which the sqlldr does not TRUNCATE the table in case of a failure.
I ran into an issue in a project where a function is recreating an index-organized table by doing:Table Structure:
CREATE TABLE table_iot( ...) ORGANIZATION INDEX OVERFLOW ...;
Recreate Steps:
1) Populate global temporary staging table (gtt) with data -- where gtt is staging for target index-organized table (iot) 2) Lock the target index-organized table (iot) 3) Copy old iot data to gtt -- gtt now contains old and new data 4) Create new index-organized table (iot2) from gtt -- iot2 now contains old and new data
[code]...
Because index-organized tables are primarily stored in a B-tree index, you can encounter fragmentation as a consequence of incremental updates. However, you can use the ALTER TABLE...MOVE statement to rebuild the index and reduce this fragmentation.The following statement rebuilds the index-organized table admin_docindex:
primary key constraint on transaction_dtl_bk is affecting the insertion of next correct rows.
CREATE OR REPLACE PROCEDURE NP_DB.san_po_nt_wnpg_1 ( dt DATE ) IS v_sql_error VARCHAR2 (100); -- added by sanjiv v_sqlcode VARCHAR2 (100); ---- added by sanjiv added by sanjiv
Oracle 11gI have a large table of 125 million records - t3_universe. This table never gets updated or altered once loaded, but holds data that we receive from a lead company. I need to select records from this large table that fit certain demographic criteria and insert those into a smaller table - T3_Leads - that will be updated with regard to when the lead is mailed and for other relevant information. select records from this 125 million record table to insert into the smaller table.
I have tried a variety of things - views, materialized views, direct insert into smaller table...I think I am probably missing other approaches. My current attempt has been to create a View using the query that selects the records as shown below. Then use a second query that inserts into T3_Leads from this View V_Market. This is very slow. Can I just use an Insert Into T3_Leads with this query - it did not seem to work with the WITH clause? My Index on the large table is t3_universe_composite and includes zip_code, address_key, household_key.
CREATE VIEW V_Market asWITH got_pairs AS ( SELECT /*+ INDEX_FFS(t3_universe t3_universe_composite) */ l.zip_code, l.zip_plus_4, l.p1_givenname, l.surname, l.address, l.city, l.state, l.household_key, l.hh_type as l_hh_type, l.address_key, l.narrowband_income, l.p1_ms, l.p1_gender, l.p1_exact_age, l.p1_personkey, e.hh_type as filler_data, 1.p1_seq_no, l.p2_seq_no , ROW_NUMBER () OVER ( PARTITION BY l.address_key ORDER BY l.hh_verification_date DESC ) AS r_num FROM t3_universe e JOIN t3_universe l ON l.address_key = e.address_key AND l.zip_code = e.zip_code AND l.p1_gender != e.p1_gender
My scenario is I need to insert into History table when a record is been updated into a tabular form(insert the updated record along with the additional columns Action_by,Action_type(Like Update or delete) and Action Date Into History table i.e History table contains all the records as the main table which is been visible in tabular form along with these additional columns ...Action_by,action_type and action_date.
So now i dont want to create a befor/after update trigger on base table rather i would like to create a generic procedure which will insert the updated record into history table taking the page alias and pade ID as the parameters(GENERIC procedure is nothing but whcih applies to all the tabular forms(Tables) contained int he application ).
I need to take a snapshot of a table before insert or update happens to that table.... in oracle 10g. I am reading the MV docs from oracle and below link..
[URL].......
how MV should be written for this and how to schedule it in dbms_jobs for auto refresh?
assuming that t1 is the table where DML operation are goin to happen so before any insert or update, snapshot has to be taken, and I am assuming that to do this it would look something like this?
create materialized view my_view refresh fast as select * from t1;
Step 1.Insert all records from the external table into the export table. Truncate the export table first
Step 2.Read in a record from the export map table
Step 3.Search through export table records looking for the key words BRANCH =. Compare the branch code with the branch code form the map table
Step 4.If a match is found mark all records in the export table for the worksheet with the global ID from the export map table as follows..The first line of a worksheet is marked by the words WKSHTS..The last line of the work sheet is marked by the words COMPANY CONFIDENTIAL..We will need to capture the line break so also mark the next line after the COMPANY CONFIDENTIAL line
Step 5.Continue with Steps 2 - 4 until all records have been processed from the export map table.
first I have to create a procedure ti insert data from external table to export table.Global id will be blank.it will be updated by the mapping table's Global Id when The EB COLUMN's data(i.e 8p,2Betc ) will match with the BRANC=NA,2Betc of the datasheet loaded from the external table.. FOLLOWING IS THE SAMPLE DATASHEET
WKSHTS AAAAA BBBBBBBBBBB ELECTRONICS INC. TIME REPORT-DATE PAGE SORT - BR, SLSREP AEC FIELD SALES REPRESENTATIVE 16:14 09/21/12 1 BRANCH = 2B EMPLOYEE NAME SALVAAG, GREGG Days in the Month 28 [code]....
THERE ARE 2 pages..I have to split this LONG REPORT STORED IN WKSHT_LINE COLUMN OF EXPORT TABLE to 2 records..like wise 500 pages are there means 500 records.. AND THEN FIND BRANCH= after that which two words will come i.e NA,2B etc if it will MATCH WITH MAPPING TABLE"S EB COLUMN"S DATA,THEN MAPPING TABLE's GLOBAL ID WILL BE UPDATED TO EXPORT TABLE's GLOBAL ID WHICH IS BLANK
