Bryan Meyers presents Embedded SQL topics to NHMUG

Bryan Meyers presented to the NHMUG user group on Thursday November 20, 2014

Introduction to Embedded SQL

In this session we’ll introduce the basic elements behind embedding SQL statements into an RPG IV program. The session will cover the syntax requirements, and discuss when embedded SQL is appropriate. You’ll understand the differences between static and dynamic SQL statements. We’ll cover how to interact between SQL host variables and RPG variables, as well as indicator variables, host structures, and indicator structures. Regardless of what IBM i release you have installed, we’ll talk about the best way to integrated SQL statements with free format RPG code, and how embedded SQL works with RPG subprocedures and local variables.

Using Cursors and Fetch

So you think a serial cursor is someone who habitually uses foul language? And fetch only applies when you’re playing Frisbee with your dog? This session will disabuse you of those notions. We’ll discuss the differences between serial and scrollable cursors, and how to use them to have your RPG program read and update database records. There will be coding examples of fetching and inserting multiple records using SQL.

Handling Errors, Dynamic SQL

We know your code would never cause an error, but just in case something slipped past the programmer who wrote the code, it’s good to know how to catch any problems that might crop up while the program is running. This session will cover return codes, communications areas, and provide some simple error handling code that you can include in all your programs. This session will also cover in detail the differences between static SQL and dynamic SQL, and point out the advantages and restrictions of each.

SQL Tips and Tricks

The session title says it all: coding tips, style guidelines, procedures, ILE issues, tricks to make SQL and RPG play better together – this session will wrap up a number of miscellaneous useful topics that will help you get started with embedded SQL, or improve your existing code. Bring your own tips, as well, to share with the group.

Craig Pelkie presents .net, mobile, and more

Getting started with .NET for IBM i developers

Even though you use the IBM i as your server platform, your shop may be using or considering application development with Microsoft .NET. Before getting started with .NET development, it is helpful to understand some of the basics of .NET, including the .NET Framework, the programming languages that are most widely used (Visual Basic and C#), the Visual Studio development environment, the ASP.NET deployment environment, and perhaps most importantly, how you can connect to your IBM i from .NET

In this session, we will look at the major features of the .NET environment and how it fits in with the IBM i.

Microsoft SQL Server for IBM i Developers

Microsoft SQL Server is a widely used database server that is found in many IBM i shops. Using database drivers provided by IBM, you can connect SQL Server to your IBM i, enabling you to move data between the two systems.

In this session, you'll learn the basics of SQL Server, how the IBM database providers can be used with SQL Server, and how to create and work with a Linked Server. You'll see how you can run SQL statements in SQL Server that access IBM i data for read, insert, update and delete operations. You will learn about SQL Server data transfer packages, and the tools that are available to create and run packages. You'll also learn about other features of SQL Server, including SQL Server Reporting Services (SSRS) and SQL Server Integration Services (SSIS).

Included with the session is a PDF lab handout that shows the steps used to create a Linked Server and run SQL commands using it.

Simple mobile programming for RPG using jQuery Mobile

Many IBM i developers create web applications with RPG or PHP, extending the reach of their company and helping users to be more productive. So if you know how to create IBM i web applications, going mobile should be simple, right? After all, all of the popular mobile devices have web browsers, so you simply bring up the pages. Right?

Unfortunately, a web page or form that looks great in a desktop browser is probably unusable on a mobile device. The phrase "fat finger" really means something when you work with data in a mobile browser.

To create a good looking, usable web form for mobile means that you need to have in-depth knowledge of HTML, JavaScript and CSS. You also need to account for different screen sizes, orientations, browsers and how users interact with mobile web applications. Fortunately, there is a readily available solution that takes into account the limitations and opportunities of mobile devices. The no-charge jQuery Mobile Framework uses an easy to understand syntax, all done using HTML. It takes care of all of the required JavaScript and CSS for you. A web application developed with jQuery Mobile is visually stunning and is readily accepted by users, since it fits in with their expectations of how a mobile web application should work. Best of all, you can easily incorporate jQuery Mobile with IBM i RPG and PHP web programs.

In this session, you will learn how you can use the freely available jQuery Mobile Framework to create easy to use mobile web applications. You'll see "before" and "after" images of web forms that have been enhanced with jQuery Mobile, and you'll see exactly what the code looks like. Once you see that you can leave out most of the hard parts of mobile web development by using jQuery Mobile, you'll be confident that you can deliver mobile applications that your users will really appreciate.

Just Enough Java: What you need to know to run Java applications on the IBM i

As a developer for the IBM i, you may need to provide applications or features that require more than RPG or COBOL. There are many Java solutions that are available and can be used on the IBM i. Your challenge, as an IBM i developer, is to get the Java code working with your RPG or COBOL applications.

In this session, you will learn the basics of getting Java applications installed and running on the IBM i. You'll learn how Java code is packaged in class or JAR files, how those files are installed in the IBM i IFS, how the CLASSPATH is used to provide access to Java code, and how to run Java applications.

You don't need to know the Java language or object-oriented programming to benefit from this session. If you just want to get a Java application installed and running on your IBM i, you need Just Enough Java to get it working!
