Sql Update In Cl Programming

AS4. 00 Tutorials Sometimes I get asked, out of all my offerings whats what and how do the pieces fit together. So lets break it down. If you are new to the AS4. IBM i world maybe youre an new system administrator, operator, programmer, manager, what have you. And you need to get up to speed fast. You want to know how to get your system to startup, make sure jobs, printers and backups move smoothly along day after day. Youll also want to learn about the object file system, jobs and subsystems, printers and output queues, system messages, and TCPIP connectivity. If want help with that, then check out my Power System Jump Start. That course covers the essential tasks every administrator needs to know. Sometimes I get asked, out of all my offerings whats what and how do the pieces fit together. So lets break it down. If you are new to the AS400 IBM i. Is there a good resource for learning how to dynamically create PowerPoint charts with VBA I can get data from external database via ADOSQL into a.

And your automatically upgraded to the latest and greatest version of the course. Pretty cool, huh Write Reports the Fast and Easy Way. Now, lets talk about data and reports. An IBM i is built around a database system so at some point youll want to get at that data. It might be a report, just to look at data, or you might want to change data in tables modify tables, or create your own tables. For that, I think the best tool is SQL. But heres what makes learning SQL many times more valuable its portable. You can take your SQL skills on the IBM i and, with small tweaks, use it on other platforms like My. SQL, SQL Server, Oracle or basically any other database system. To get started with SQL today, youll want to check this site out http www. Now, that leaves custom reports. At some point youll HAVE to write a custom report. And if you dont have a reporting program already, two good alternatives exist. I have this long string in one of the columns of the table. I want to get only specific information My Table structure Col1 123 Col2 AAAAA Col3 Clent. Heres what I hate about third party reporting packages theyre usually not made for power users so they are larded up with features and a bunch of screens that actually slow you down. But for quick reports and queries, SQL alone will get the job done probably 6. You just start up an interactive SQL session and change the output to a spool file run the SQL statement and youre done. If you have SQL statements you run often, store them in a Source Physical File and then you can call them up quickly with the RUNSQLSTM command. But, for the other 4. Query4. 00 and Query Manager are good choices. Query4. 00 is a bit old school but it works really well. ITKE/uploads/blogs.dir/254/files/2013/04/RPGLE-Example.png' alt='Sql Update In Cl Programming' title='Sql Update In Cl Programming' />Query Manager is not as well known, but you probably already have it installed and licensed on your system. Many people do and dont even realize it. A HUGE difference between them is the use of SQL. Query4. 00 doesnt use SQL, and Query Manager does that means Query Manager can faster because it uses the modern SQL engine on the system. For more about writing Query4. IBM i Query reports, go here http www. To get started with Query Manager, youll want to check this out http www. And at just 3. 3, my Query Manager course is the bargain of the century A note about those courses Im going to merge them together into one big report writing course very soon and the price will very probably go up. So get it NOW while its a bargain deal. How to Write Your Own Custom Programs. Finally writing programs. Writing custom RPG programs is when my knowledge of the system really took off. When coding, you start to learn more about the DB2 database, the system, how its structured and just commands in general. Most folks write native programs on the platform with the RPG and CL languages. CL, or Control Language, really creates programs using commands. Sql Update In Cl Programming' title='Sql Update In Cl Programming' />But it does have features for logic, variables, looping and control like youd expect in a programming language. When you want to start automating tasks on your system, CL is a good place to start. RPG is a natural step if you want to write native type programs. Its really good for making detailed reports that need lots of logic. Sql Update In Cl Programming' title='Sql Update In Cl Programming' />And if you want to write green screen programs, RPG along with DDS is the way to go. If your into web apps, then PHP is available. I dont yet have any programming courses but I keep hearing from you that youd like one. So watch this space. Ill probably start with a CL course and go from there based on your feedback. Until then, Ill recommend Bryan Meyers and Judi Yeagers book Programming in RPG IV. Its how I learned RPG III and RPG IV. And I spent many late nights at work after hours, going through that book to learn RPG IV. And you can find copies of that book on Amazon. How IBM i Skills Become Second Nature. When you pick up one of my courses youll discover they are accelerated training. As an IT professional, I get that youre busy. You dont have time to wade through a thousand page manual to find a command. And forget about trying to follow a BORING audio recording an audio might work for a Dr. Deyer self help program  but audio is not for hands on technical tasks where you learn best by doing. My courses shortcut the process. They make use of live video tasks being done on an actual AS4. IBM i system. Dont you just HATE it when you read something in a book, try to repeat what the author did, and discover theres a mistake or typo and it doesnt work. Youre left scratching your head, and completely frustrated. And its not like the publisher sends you a revised copy. In fact, your lucky if they even have a forum where the author  might  might possibly poke in to fix publishing or editing mistakes. Ive eliminated all that hassle and frustration with the step by step videos and you see this especially in the SQL Course where being precise matters you see how its done. Nothing is left out. You can trust what youre learning works, and you can prove that it works by repeating the same EXACT SAME thing on your own system. My Best, John Andersen. Tags   AS4. 00 DB2 Query4.
