Sql updating multiple rows

OR is it that, sql allows only UPDATEs with one set of values to n rows. e.g insert into TABLE1 select column1, column2, column3 from TABLE2 This is perfectly valid, assumes TABLE1 has only three columns, column1, column2, column3. Hi, Does SQL support update to multiple rows where values coming from a sub-query?

Hi, Does SQL support update to multiple rows where values coming from a sub-query?

e.g insert into TABLE1 select column1, column2, column3 from TABLE2 This is perfectly valid, assumes TABLE1 has only three columns, column1, column2, column3.

For example, if update statement modified 10 rows, create table dbo.

Data ( ID int not null, Value varchar(32) ) go create trigger trg Data_AI on dbo.

You can do this two ways: MERGE INTO T USING S ON = WHEN MATCHED THEN UPDATE SET c1 = S.c1, c2 = S.c2 This is newly added and AFAIK supported only by Oracle 9i ( ) and DB2 V8.1 for LUW ( ) In SQL92 (should work in MS SQL Server and any other SQL based RDBMS): UPDATE T SET (c1, c2) = (SELECT c1, c2 FROM S WHERE pk = T.pk) WHERE EXISTS(SELECT 1 FROM S WHERE pk = T.pk) or use an IN predicate: UPDATE ...

First, indicate the table that you want to update in the UPDATE clause.For example, the following C code fragment prompts for a country name and a percentage change in population, then updates all cities in that country with the new population: Use cursors to select rows for update when prompting users for changes on a row-by-row basis, and displaying pre- or post-modification values between row updates. I want to update the name, address and age sequentially. like ("y J","ht43",34) ("rt","fd43",36) ("hg","hgd4",40) ("ui","udg6",28) How to update the rows sequentially with these values with update query? Age FROM Your Table Ranked AS t INNER JOIN New Values AS v ON v. Row Num; CREATE TABLE #T (ID INT, Name VARCHAR(2), Address VARCHAR(5), Age INT); INSERT #T (id, name, address, age) VALUES (1, 'as', 're3', 20), (2, 'dg', 'ht5', 21), (3, 'hf', 'ujy6', 23), (4, 'ku', 'tr5', 25); WITH Your Table Ranked AS ( SELECT t.*, Row Num = ROW_NUMBER() OVER(ORDER BY ID) FROM #t AS t ), New Values AS ( SELECT t.*, Row Num = ROW_NUMBER() OVER(ORDER BY Name) FROM (VALUES ('y J','ht43',34), ('rt','fd43',36), ('hg','hgd4',40), ('ui','udg6',28) ) AS t (Name, Address, Age) ) UPDATE T SET Name = v. My question: Is there any way to UPDATE values to TABLE1 similarly? My question: Is there any way to UPDATE values to TABLE1 similarly? We will use the employees and dependents table to demonstrate the UPDATE statement.
