Universal database definition3/25/2023 ![]() ![]() When you click a column on this page (the figure above shows the Column column), you can select a corresponding item from the drop-down list that appears. In addition to this, ensure that the Build and Enable debugging check boxes are selected, and then click Next. Type a name for this stored procedure (for this article, use the name STAFFSELECTION) in the Name field. ![]() The New SQL Stored Procedure wizard opens. You can use the Data Definition view in Rational AD to build stored procedures for DB2 UDB for i5/OS and DB2 UDB for z/OS databases as well (provided you have the DB2 Connect product installed however, this article assumes you are using an installation of DB2 UDB on the Linux, UNIX, or Windows platform).Ģ. Since the DB2 UDB V8.2 for Linux, UNIX, and Windows release, you no longer require a compiler to build SQL/PL procedures. NET CLR-based stored procedures in DB2 for Windows data servers. In fact, Rational AD can be used to test any kind of stored procedures, including. ![]() You can use Rational AD to create both Java-based and SQL-based stored procedures. The stored procedure language used by DB2 UDB is called SQL/PL – it is an open ANSI-compliant language for writing business logic in databases. Expand the schema where you want to create your stored procedure, right-click the Stored Procedures folder, and select SQL Stored Procedure, as shown below: To build this stored procedure in the Rational AD IDE, perform the following steps:ġ. For this example, the source of the employee data is the STAFF table, which resides in the SAMPLE database. In this section, I will show you how to build an SQL/PL-based stored procedure that takes a numeric input (which represents a department number) and returns the names of employees who work in the corresponding department. ![]() However, it is generally considered a ‘best practice’ to fully qualify an object with its schema name. If you are logged on to your system with the same user account that you used to create the SAMPLE database in Part 1, then you may not have to explicitly specify your schema to qualify the STAFF table when writing SQL. Specifically, we will be working with the STAFF table, so I would qualify this table as PAULZ.STAFF. Whatever user ID was used to create the SAMPLE database (the system user account you used when you entered the db2sampl command in Part 1) will be used for the user tables in this database. Note: In the previous figure, I have highlighted the PAULZ schema. Right-click the SAMPLE database entry in the Database Explorer and select Reconnect, as shown below: For this article, we assume you imported the SAMPLE database.Īs a quick refresher, you can follow the steps below:ġ. In order to build a stored procedure using Rational AD in your database, the database must be in your project. To complete the steps in this part of the series, you need to import the SAMPLE database (or any database for which you want to create a stored procedure) into your DATABASEJOURNALSERIES project. In this section, I will show you how to build a stored procedure using the Data Definition view. Note: Ensure that you are in the Data Perspective when performing the steps outlined in this article. You will learn how to build stored procedures, use variables within them, and how to deploy and test them. In this part, we will look at how to build stored procedures using the Data Definition view. Part 2 introduced you to some of the many capabilities provided by the Data Definition view in the Rational AD integrated development environment (IDE). In Part 1 of this series, I discussed how to use the Database Explorer view in the IBM Rational Application Developer for WebSphereSoftware (Rational AD) product to create and work with IBM DB2 Universal Database (DB2 UDB) for Linux, UNIX, and Windows database connections. ![]()
