YOu coud chask on your phpmyadmins ar here piliapp.com/mysql-syntax-check/Nice explanation and i found some error message as Multipart identifier table1.column1 when i executed sample query using your example. Col1 IN (21, 31) GOMy Query which executed:: UPDATE t1 SET t1. In particular, filter or join conditions applied on the result of one of those calls have no effect on the results of the other.Specifies the condition to be met for the rows to be updated.When asked the reason was he had no idea how to use multiple tables with the help of the JOIN clause in the UPDATE statement. Additionally, we want to update the values of Col2 and Col3 only. When you look at this it looks very simple but when we try to think the solution, I have seen developers coming up with many different solutions for example sometime they write cursor, table variables, local variables etc. Col2)) UPDATE CTE SET Col1 = _Col1, Col2 = _Col2from stackoverflow.“UPDATE Table1 SET Col2 = t2. For more information about predicates and search conditions, see Search Condition (Transact-SQL). Table2; USE Adventure Works2012; GO IF OBJECT_ID ('dbo.CURRENT OF Specifies that the update is performed at the current position of the specified cursor. Table1', ' U') IS NOT NULL DROP TABLE dbo. Table2', ' U') IS NOT NULL DROP TABLE dbo. Table1 (c1 int PRIMARY KEY NOT NULL, c2 int NOT NULL); GO CREATE TABLE dbo. Table2 WHERE CURRENT OF abc; GO SELECT c1, c2 FROM dbo.
As you can see that using JOIN clause in UPDATE statement it makes it very easy to update data in one table from another table. Col2 AS _Col2 FROM T1 JOIN T2 ON T1= T2/*Where clause added to exclude rows that are the same in both tables Handles NULL values correctly*/ WHERE EXISTS(SELECT T1.
A view with an INSTEAD OF UPDATE trigger cannot be a target of an UPDATE with a FROM clause.
Note Any call to OPENDATASOURCE, OPENQUERY, or OPENROWSET in the FROM clause is evaluated separately and independently from any call to these functions used as the target of the update, even if identical arguments are supplied to the two calls.
The search condition can also be the condition upon which a join is based.
There is no limit to the number of predicates that can be included in a search condition.
