PL/SQL :: Lock Row In 1 Table While Update Other Tables
Oct 15, 2012I want to read 1 table. If the date is less than today, I want to update 4 other tables. I only want to do this update once a day.
While the 4 other tables are being updated, I want the other web users to pause for the update while this procedure runs.
Is there a better way to do this?
Here is what I have:
CREATE OR REPLACE PROCEDURE TEST_TODAY2 AS
-- to create the table
-- create table test_today(updated_date date);
-- insert into test_today(updated_date) values (sysdate-1);
-- select * from test_today;
cursor daily_update_cur is
select updated_date from test_today
for update of updated_date;

View 2 Replies View RelatedLock Child Table By FOR Update Clause?
May 7, 2013I am using the Oracle 10g and I have question related to "for Update" clause.We have the data warehouse db, so no foreign key constraint between parent and child.We process the data files every hour, the condition is If we find the row in parent table then we go and look into child tables and perform insertion (if no corresponding record is present) or updation (if one corresponding record is present) in the child table.
The problem is If I run the two process simultaneously for the same kind of data, and if no record is present in the child table then it create the duplicate in child table.My question is if I use FOR Update clause while selecting the data in parent table will it lock the child table for any insertion or updation?
Ex- We have employee table for employee 1
In my data files I have the row for employee 1, so when I run the select query on employee table I found 1 row.The I look the child table "Salary" as there is no record for emp_id =1 in this table I insert the record for this
Emp_id Salary
1 500
The problem is if both the process run at same time then I get duplicate rows in child table
Emp_id Salary
1 500
1 500
we do not want the duplicate row insertion. Can I lock the child table during first process run

PL/SQL :: Index-Organized Table Truncate Vs Lock / Stage / Drop / Recreate?
Apr 24, 2013I 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:
ALTER TABLE admin_docindex MOVE;

Manually Fire A Trigger
Sep 10, 2010I disable the triggers when I program. what the program is doing behind the scenes. So if I insert into a table, the trigger would fire and insert into another table. Disabling the triggers shows me that I need to insert into both tables. This also allows me to have the primary key in my conversion tables match the database.
With that being said, can I tell the trigger to fire after the fact?

View 13 Replies View RelatedReports & Discoverer :: How To Add Aggregate Functions Manually
Oct 30, 2010i want to create a blood donor report, which consists of his profile, donations_n_tests details, donor_to_patient tracking. each is a different table which i have imported to the layout.
now the problem is that for the 1st ever layout that i make via the report builder wizard, it offers me to choose aggregate functions (like sum, cout, avg, etc). but for the rest of the tables that i import into this layout via ADDITIONAL LAYOUT OPTION (report block. it does not offer me these summary functions.
actually i can only configure aggrigate functions via the report layout wizard, perhaps report builder is not that friendly like form developer where we can put a display item set calculation mode to summary and specify the column for the aggregate function.

View 1 Replies View RelatedManually Find Difference In Days And Multiply By 24
Apr 25, 20111) First Problem:
Difference in hours is supposed to be 35 but it comes as 34.When i manually find the difference in days and multiply by 24 it comes as 34.999999999 and floor converts it as 34.. But when i execute the difference between dates alone and convert to 24 it shows as 35. So when i apply floor to this, it should be 35 instead of 34 right?
