Oracle 10g - Take Snapshot Of Table Before Insert Or Update Happens To That Table
Dec 28, 2010
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;
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 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?
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.

how to adjust a total (counter) after a record is inserted into a table.
the dilemma i am facing is we are using third party software for our fundraising operations so I have no control over what gets done in the background as users process their daily batches into the system. below is the scenario:
during batch posting records are inserted into the paytable, on some pledge donations donors will send overpayments when fulfilling a PLEDGE(as is the case with donor 16084) therefore the system will split the payment during the process and will assign a trantype of 'PP' to the exact pledge amount and a 'PPO'(pledge payment overage) towards the balance. additionally as records get inserted into paytable there is counter of those paytable records going into the appealtable for that particular appealcode so in the case above when batchno 20120808 is completed appealtable.total# will show 103 and total$ will show $2532($10,$12,$10,,,I did not include payment$ since that is not the focus of this issue and will not change).
mgt wants the counter into the appealtable to be 2 instead of 3 records since the two records that were split(same split_transnum) should be recorded as one response not two.
I have tried writing an after insert trigger(dreaded mutating table error) and can't seem to figure out how to update the counter to the appealtable after records are inserted into paytable. below is some code I've been working with but it's not working.
CREATE OR REPLACE TRIGGER PPO_Payment AFTER INSERT ON paytable FOR EACH ROW
I want to update a row in a table say Table A and the updated row should be inserted into another table say Table B. I need to do it in a single SQL query and i don't want to do it in PL/SQL with triggers. And i tried with MERGE statement but its working with this scenario.
(Note: I'm using Oracle Database 10g Enterprise Edition Release 10.2.0.1.0).
i have 2 identical tables....the trick is with regards to one column say column A,the first table TableA is constantly having data inserted and data updated, what im trying to do is create a before insert or update trigger that looks at column A and if column A=20 it changes this to 5 and inserts this into the tableB, everything else with the exception of Column A will be the same:-
this trigger i have done works but doesnt change the value of column A (INPUT_NADI) as i dont know how to do this:-
CREATE OR REPLACE TRIGGER UPDATE_TRG_NP_NE1_T0 BEFORE INSERT ON TESTNSS.NP_NE1_T1 REFERENCING NEW AS NEW OLD AS OLD FOR EACH ROW DECLARE BEGIN INSERT INTO NP_NE1_T0 VALUES [code]....
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've a one history table in which I'm putting approval history data.
For any transaction id you may have more than one record with approval status APPROVED,REJECTED,ERRORED,OVERLIMIT etc
Another program selects records from this table by passing transaction_id. For transaction id, it needs to check the most recent approved record exist or not ? If it's there then updating the record by adding comments to comments field of the same record and then delete all other records for the same transaction id.
If it does not exist then delete all other records and create one with approved status?
What's the simple and best approach to do this (sql or pl/sql)?
I am trying to insert rec into target table if those rec are not existing and trying to update those rec if they already exists from three source tables.I had seen in posts that merge cannot be used with cursor.

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?

I would like to UPDATE the columns p1 and p2 of my table student (studentid:pk,name,p1,p2,...) for a given studentid.and I have a when-button-pressed trigger with this
UPDATE student SET student.p1=:validation.proj1, student.p2=:validation.proj2 where UPPER(student.studentid)=UPPER(:validation.studentid);commit_form;
when I run my form with a correct studentid, I got this error: FRM-40508: ORACLE error: UNABLE to INSERT record
but it is cworking correctly in sqlplus; and I have all priveligies.
I am trying to develop a form consisting of a key block and a single data block. The problem is that the driving table is not the table that needs to be updated.
user wants the following layout:student Advisor ID# name degree major Concentration ID# name The driving table (TABLE A) will supply the first 5 fields. The advisor ID comes from (TABLE B).
The user needs to update the adviser ID# field associated with the student ID# field. The form is to be tabular listing all students. I've seen some info on using procedures to insert, delete, update, query and lock tables, but i'm just not sure if that's what is needed.
I have two table and trying to update tableA with data from tableB but gives an error. My TableA has columns - colA,colB,colC,colX and table B has columns - colA,colB,colX. Sample data looks like this:
this is the query I wrote update tableA a set (a.colX)=(select (b.colX) from tableB b where a.colA=b.colA and a.colB=b.colB);
When i run it gives this error:single row subquery returns more than one row.
tableB has only 1 value for colX for each colA,colB record but tableA has mutiple colA and colB repeated but for all of thsoe in table A i want to update the tableB.colX value for matching colA and colB.
I have a Clob file as a in parameter in my PROC. . File is comma separated.need procedure that would parse this CLOB variable and populate in oracle table .
primary key constraint on transaction_dtl_bk is affecting the insertion of next correct rows.

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
creating an sql script that can update info from one table in dbase1 to another table in dbase2 that has the same columns and if possible insert date and time in one column when the synchronized is done?
What would cause Oracle to insert duplicate rows into a table? Could a join of two tables in the initial query assigned to an application page cause ORacle to insert an extra row into a table when an update to data value occurs? I have no insert triggers and no foreign keys assigned to the table. I am not sure what would cause Oracle to assume that an insert of a row must occur. I want to prevent that insert.
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
