sql updating multiple columns from another table-29sql updating multiple columns from another table-1

I use this statement: update table1 set col1 = col2 col3 where col4 = 'OK' and exists (select distinct 1 from table2 where table1.col_x = table2.col_x2 and table2.col_y2 = 'super OK') This update works, but is too slow... September 26, 2008 - pm UTC you can use merge merge into t1 using t2 on (t1.x = t2.a) when matched then update set y = t2.b; if there exist duplicated by t2.a (more than one row with t2.a having the same value), the merge will fail at runtime when it encounters you trying to modify Y in a non-deterministic fashion. Can we use the WHERE clause in the merge statement?

Here you want to set a qty to a constant for some records - and you 'anti-join' to the other table, not join. create table types 2 (type varchar2(1), 3 description varchar2(50), 4 factor number(4)); ************************************************************************ Insert table: insert into types values ('A','Monthly','12') / insert into types values ('B','HOURLY','1796') / insert into types values ('G','Daily','224') / insert into types values ('H','Per Visit','') / insert into types values ('I','Per session','') / ******************************************************************** insert into class_test values ('0001','3,281.18','4,177.64') / insert into class_test values ('0002','3,779.27','4,820.00') / insert into class_test values ('0003','4,779.27','5,820.00') / insert into class_test values ('0004','5,779.27','6,820.00') / insert into class_test values ('0005','7,311.45,'10,402.64') / insert into class_test values ('0005','','20.83') / insert into class_test values ('0006','','14,528.60') / insert into class_test values ('0007','5,001.82','5,727.91') / ****************************************************************** insert into jobs values ('0001','CSI','A','','50131.68') / insert into jobs values ('0002','TTI','A','','200') / insert into jobs values ('0003','SSP','A','','') / insert into jobs values ('0004','CCC','A','','') / insert into jobs values ('0006','CIO','A','','') / insert into jobs values ('0007','CIO','A','','') / It should be update rows in JOBS table where rate_type = 'A', and ITEM_NO of JOBS table should be match with ITEM_NO of class_test table. Name Marital Status Mobile Phone Email I want to update table A (Name and Marital Status) using table B data, considering that ID matches in both tables, and using a designated ID (the use of Id may be optional, but for sake of simplicity lets assume we only want to update 1 row, but multiple columns at same time) Update table A set table A. Interestingly the Update that is suggested by you takes 12 hours and Update using the PL/SQL cursor style takes 8 hrs consistently on the live environment! thanks in advance June 04, 2008 - pm UTC create table has to be followed by indexing, grants, constraints and everything else - have you accounted for THAT. Unfortunately i cant get the tkprof as i dont have access to. if you were asked to pilot a plane with a blindfold on - how well do you think you would do. I cannot tell you how to make something more efficient if I do not know what is impeding the efficiency in the first place.

( Client number is consist of branch, Number, Sub Number Currency Code ) We have one big transaction table around 1 million records, having many columns, and at many places client numbers are stored from account master under various columns 1. You told me to use update ( select old.old_account_number, new.new_account_number from old_table old, mapping_table new where old.old_account_number = new.old_account_number ) set old_account_number = new_account_number; But I think my questions still reamin unanswered 1. In your answer only one number say client number will get updated.

I have to update a transaction table where mapping is existing with old account no and new account number.

Update data in table A based on two or more common columns in table B.The differences in syntax are quite dramatic compared to other database systems like MS SQL Server or My SQL. Updates based on two or more common columns are normally used for tables where multiple columns work together as a primary key (known as composite primary key).Secondly you have shown me to update table with "KEY PRESERVED" method. IT NEEDS THIS LOGICALLY regardless of the method used, so just add it (for if a row in OLD joins to more than one row in NEW -- you are hosed, you cannot update this data, therefore NEW has a unique/primary key, add it to facilitate the update) I had a similiar query and i tried applying to my tables.
