You can then update the View which will then update the underlying tables.
REF_NAME = @REF_NAME from table2 B inner join table1 A on B. So don't use END, this not a even question of good or bad practice, you might close the block you're in and find unexpected output But you are trying to affect multiple tables with an update statement that joins on multiple tables. However, updating two tables in one statement is actually possible but will need to create a View using a UNION that contains both the tables you want to update.
Microsoft is conducting an online survey to understand your opinion of the Msdn Web site.
WAprrs = 'start,stop' FROM Table2 JOIN @ids i on = Table2.id; COMMIT; Sorry, afaik, you cannot do that.
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.
However, the easiest and the most clean way is to use JOIN clause in the UPDATE statement and use multiple tables in the UPDATE statement and do the task.
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.
How can I update multiple tables in My SQL with a single query? The WHERE clause is evaluated separately for each table. Some lessons are learned the hard way, this one was learned in the terrifing way. That's usually what stored procedures are for: to implement several SQL statements in a sequence.
