We check for an error and find that there is no such city as Vienne. But rather, Wien in German or Vienna in English:. We can also update the invoice table based on a customer. For example, suppose we need to give a special discount on the total invoice for Austrian customers who spent more than 20 dollars on Rock and Metal genre 1 and 3.
The subset is easily extracted with the following query:. We can apply it updating the total invoice table based on the above query using the below CTE:. How does this work in Oracle? We must do some shortcuts in order to do something similar.
We can make use of a subquery and an IN filter. We will transform the UPDATE statement using the above query as a subquery, but we will extract the primary key Invoiceid in order to do the update:. That was quite easy, but let's suppose that we need to an UPDATE based on another big table and use the value in the other table. But this time it is a select statement with the primary key and the total that we'd like to update.
Connect and share knowledge within a single location that is structured and easy to search. I want to update my db records, which are related one to many. Please consider the following example :. Table person has phone and fax columns. Now I added phone and fax columns to the contact table and I want to copy the values of fax and column to the contact table from person table.
The error points to a syntax problem. When you want to update multiple columns at once, you list all of the columns to be updated first, followed by all of the values to use in the same order that the columns are listed.
For example:. Or, instead of doing an update with a correlated sub-query as above , you can write it as a merge:. Sign up to join this community. Sign in with Email.

If table or the base table of view contains one or more domain index columns, then this statement executes the appropriate indextype update routine.
You cannot update rows in a read-only materialized view. If you update rows in a writable materialized view, then the database updates the rows from the underlying container table. However, the updates are overwritten at the next refresh operation. If you update rows in an updatable materialized view that is part of a materialized view group, then the database also updates the corresponding rows in the master table.
Oracle Data Cartridge Developer's Guide for more information on the indextype update routines. Specify the name of the partition or subpartition within table targeted for updates. You need not specify the partition name when updating values in a partitioned table. Specify a complete or partial name of a database link to a remote database where the object is located.
You can use a database link to update a remote object only if you are using Oracle Database distributed functionality.
