When I try to update only the missing data the non-matched data is also updated but to NULL. The reason some of your rows are getting NULLs updated is due to the subquery.When the subquery fails to find a matching row in tbl B, the subquery returns NULL.In place of 3 separate unwieldy INSERT, UPDATE and DELETE statements with conditional sub-queries, the all-in-one MERGE does the job in one shot.Consider another table STUDENT_N, which holds updates for the target table STUDENT.

works fine when I try to update all the records in tbl A, however, in this case I only have missing data which I have identified and populated in tbl B. I spend an inordinate proportion of design time of an ETL system worrying about the relative proportion of rows inserted vs updated.I want to test on a level playing field and remove special factors that unfairly favour one method, so there are some rules: TEST (Update Source) - 100K rows TEST (Update target) - 10M rows Name Type Name Type ------------------------------ ------------ ------------------------------ ------------ PK NUMBER PK NUMBER FK NUMBER FK NUMBER FILL VARCHAR2(40) FILL VARCHAR2(40) Not many people code this way, but there are some Pro*C programmers out there who are used to Explicit Cursor Loops (OPEN, FETCH and CLOSE commands) and translate these techniques directly to PL/SQL. If you omit the WHERE clause, all records in the table will be updated! The WHERE clause specifies which record(s) that should be updated.I include it here because it allows us to compare the cost of context-switches to the cost of updates.DECLARE CURSOR c1 IS SELECT * FROM test6; rec_cur c1%rowtype; BEGIN OPEN c1; LOOP FETCH c1 INTO rec_cur; EXIT WHEN c1%notfound; UPDATE test SET fk = rec_, fill = rec_WHERE pk = rec_cur.pk; END LOOP; CLOSE C1; END; / This is the simplest PL/SQL method and very common in hand-coded PL/SQL applications.Answer: The landmark book "Advanced Oracle SQL Tuning The Definitive Reference" is filled with valuable information on Oracle SQL Tuning.This book includes scripts and tools to hypercharge Oracle 11g performance and you can buy it for 30% off directly from the publisher. ), how I might cluster rows together that are subject to updates, and what I might do if I just get too many updates to handle. The fastest way to update every row in the table is to rebuild the table from scratch. Case 2 is common in Data Warehouses and overnight batch jobs. I worry about how ETL tools apply updates (did you know Data Stage applys updates singly, but batches inserts in arrays? The two most common forms of Bulk Updates are: Case 1 is uninteresting.update existing rows in a table or insert new rows depending on a match condition.This is typically the case when you have to synchronize a table periodically with data from another source (table/view/query).SQL select * from employee; ID FIRST_NAME LAST_NAME START_DAT END_DATE SALARY CITY DESCRIPTION ---- ---------- ---------- --------- --------- ---------- ---------- --------------- 01 Jason Martin 25-JUL-96 25-JUL-06 1234.56 Toronto Programmer 02 Alison Mathews 21-MAR-76 21-FEB-86 6661.78 Vancouver Tester 03 James Smith 12-DEC-78 15-MAR-90 6544.78 Vancouver Tester 04 Celia Rice 24-OCT-82 21-APR-99 2344.78 Vancouver Manager 05 Robert Black 15-JAN-84 08-AUG-98 2334.78 Vancouver Tester 06 Linda Green 30-JUL-87 04-JAN-96 4322.78 L.

Pew is saying roughly one in every eight Baby Boomers (born from 1946 to 1964) is online and searching for loving. Experts - and Boomers who are online and dating - are quick with opinions. "I met my sweetheart online," said Gretchen Asher, a 56-year-old Portland, Ore. "We just celebrated our two year anniversary.” They met on a free site called Plenty of Fish and, said Asher, “It’s funny, I had a perception that the free online sites served a lower quality single and I was just on Match.com," she said.
