SQL 101: A Simple Way to Add Data to the DB: the Insert Statement PDF Print E-mail
Tips & Techniques - SQL
Written by Rafael Victoria-Pereira   
Friday, 28 August 2015 00:00

You've learned how to query the database with Select; the next logical step is to learn how to add data to your tables. You can do that with RPG and DFU, but SQL's Insert statement provides an interesting alternative.

 rafael victoria preiraWritten by Rafael Victória-Pereira

RPG and DFU provide ways to add new records to your files. RPG forces you to write a program, regardless of how simple or small the data you want to add is, and DFU is a not the friendliest tool to manipulate data. It can be useful to quickly change a couple of records, but it's not adequate for massive data insertion. SQL's Insert provides an interesting functionality, somewhere between the flexibility-yet-slowness of the RPG program and the quickness-yet-unfriendliness of the DFU tool. Let's take a look this SQL instruction.

Partner TechTip: IBM i's Greatest Strength Is Also Its Worst Security Weakness PDF Print E-mail
Tips & Techniques - Security

What happens when reputation collides with reality?

robin tatamWritten by Robin Tatam

According to IBM's website, "the IBM i operating system is considered one of the most secure systems in the industry." It's true that IBM i has a near-legendary reputation as a secure system based on its world-class integrity features and security controls. But, as the author of PowerTech's annual "State of IBM i Security Study" for the past seven years, I feel the description as "secure" is often dangerously misunderstood.

Drag and drop save files (SAVF) between your PC and the IBM i. Search PC files with a preview of the found lines. Access your PC like Windows Explorer does.

sam lennonWritten by Sam Lennon

There are some PC capabilities built into the Rational Developer for i (RDi) IDE that may not be immediately obvious. In this TechTip, I'll introduce you to a few that you may find useful. Note that this article is based on running RDi (or WDSc) on Microsoft Windows. There is nothing here that addresses a Mac- or a Linux-based machine.

TechTip: Wireshark, Examining a Single Frame PDF Print E-mail
Tips & Techniques - System Administration
Written by Lisa Bock

When first learning how to use Wireshark, it can be overwhelming. This TechTip has us dissecting a single frame.

lisa bockWritten by Lisa Bock

Editor's note: This article is a follow-on to TechTip: Get Familiar with Wireshark, an Open-Source Packet Analysis Tool.

 

I have spent years immersing myself in packet analysis, and to help you get started, we will examine one single frame in Wireshark. In this example, I have opened a pre-captured trace file shown in Figure 1, where I have requested a webpage. The conversation is between the two endpoints 23.15.7.155 and 192.168.1.102.

TechTip: PHP Classes, Part 1 PDF Print E-mail
Tips & Techniques - Scripting

Ready to get started coding object-oriented PHP? Me too, so let's get this show on the road.
david shireyWritten by David Shirey

A couple of months ago, I promised that we would start a series of TechTips for PHP designed to get you into writing modular, OO PHP. Or at least that's what I think I promised; it was a couple of months ago, and a lot has happened.

 

Then PHP 7 came along, and I ended up doing a couple of TechTips revolving around what that entailed. But now I'm ready to pick up where I left off, even though I hadn't really begun anything yet. Story of my life.

From green screen to GUI to the new web interface, Robot SCHEDULE job scheduling software includes new features that make mobile job schedule management easy.

tom huntingtonWritten by Tom Huntington

When Doug Engelbart delivered the "mother of all demos" in 1968, did he know what kind of controversy would come from the introduction of his "X–Y position indicator," better known today as a computer mouse?

 

What once was a wooden box with wheels has evolved into sleeker tools, but the debate still rages. Is a mouse more ergonomic than a keyboard? When compared to green screen or command line interfaces, does using a mouse to navigate a graphical display actually save time? Does a mouse limit functionality?
