How to update records information in the database is essential for the development of daily activities in development environments, so we will learn how to use the following UPDATE statement in Oracle database.
The syntax is very simple as shown below:
SET [Column] = [Value]
As a practical example, we will upgrade the country field of all records from table of products.
SET country = ‘USA’
In the example all records are updated with the information passed on, but this kind of situation is not so common. The UPDATE command needs to be used carefully and one of the ways to prevent possible errors is using the conditional WHERE thus only the record that satisfies the condition is updated.
SET Name = ‘Tv’
WHERE cod_prod = 1
In the above example we update the name of a product from the code that is referencing the database, this way we avoid other records are also updated with the same information.
The Oracle database has become increasingly common in web development environments, especially those that use PHP as default language, because of that understanding how it works is essential to any professional.

Oracle is one of the most respected DBMS in the world, created in the late 70s by Lary Ellison, quickly turned into one of the most used and trusted. Your security scheme and processing capacity were some of the features that gave it that title. One of the great advantages of Oracle has always been a pioneer in several features for databases, one of the firsts to think about a model for the web in the late 90s.It is very common to find the database Oracle working with PHP applications in development environments.
As it is a powerful DBMS, it is common to see projects using Oracle. Several types of applications work using it, so that it is very common to find large PHP projects that need to connect with this type of database. But depending on the tool used to develop the application, the connection may have problems. An external driver that may be used to make the connection may require development hours until it works perfectly. In addition, issues related to security of the connection (data access) also can be a problem.
Therefore it is essential to have a tool that can assist you in this aspect. With Scriptcase you can easily connect to Oracle database, all you need to inform to connect to the Oracle is:
- Connection Name: It will help you identify the connection among the others.
- DBMS Driver: it Will show a list with all drivers available.
- TSNAME: Should be informed the IP of the server where the database is installed and the instance name created in the Oracle installation.
- Port: The port that you want to use to connect to your database.
- Username: Username for the user from the database.
- Password: The password from the previous selected username.
Once you connect Scriptcase with your database, it will read your tables and create applications based on the desired tables. Scriptcase will identify all special characteristics from your table, such as primary keys, foreign key, auto-increments, among others, and will show that at the application level. All the CRUD (Create, Read, Update and Delete) actions will be managed by the Scriptcase. On forms and reports all the navigation, searches and filters (Static or Dynamic) will be also handled by Scriptcase automatically.
Scriptcase support stored procedures and all SQL statements (joins, order by, group by, among others) of Oracle, why lose time when you have Scriptcase to help you out?! Download it now and test it free for 20 days!
