Updating multiple rows oracle
You can also limit the rows being updated using the TOP clause.Suppose you want to update only two rows with a new price then you can run the following code: This code updates two random rows in my Toy table.There may be times when you need to write some code to update a row, or set of rows in a table.This is when you need to know how to use the UPDATE statement to update those rows.By doing this I can see what my WHERE condition will return to make sure it identifies the same rows I want to update.Once my SELECT statement does return the correct rows I can then copy the WHERE clause from my SELECT statement, and paste it into my UDPATE statement code.In my first TSQL script above, when I create the TOY table, there is typo in the first Toy Name.
