Get Running - TechCrystals Code Package™

Get Running with the IBM Db2 for i .NET Provider

Get Running with the IBM Db2 for i .NET Provider

The base product for this TechCrystals Code Package is a fast-path tutorial and working web pages source code bundle for the business software developer targeting use of Db2 for i SQL in the Visual Studio IDE, or production IIS web server.

There are also two optional add-on components that help boost productivity for developers already working with IBM SQL PL stored procedures (or  planning to), so please see below for that... 

Within minutes, using just our base product, your Db2 for i database and any version of the Visual Studio IDE, you'll be protyping all sorts of dynamic SQL within a zero-footprint web page (so most any browser without any add-on requirements).  And you'll have the capability to tap into the latest Db2 for i features on your IBM i Power System.  For developers somewhat new to c# or Microsoft "web forms", you will be able to see and enjoy how results can be produced in a gridview using a minimal amount of c# in the "code-behind" the html (and xhtml in the case of the gridview).  For column headings, you get nice dynamic formatting, and you can pull from whereever and however in order to get your user-friendly column headings out from under the covers, such as by pulling from views, physical files, logical files or even SQL field renaming syntax.  Incidentally, column duplicates created via dynamic joins without discreet column lists are resolved automatically in the gridview control (yea!).  This makes it a little challenging in Add-On 2, but more on that later.  

The base package also includes everything you need to know to get IBM's Db2 for i .NET Provider downloaded and installed and configured in a ASP.NET OO web forms project for your desktop (with Visual Studio, even community edition) or for production in an IIS web server.

SQL Prototyping Web UI and Stored Procedure Test HarnessAdd-On 1 is a generic test harness for Db2 for i stored procedures that allows library list logic.  It allows the developer or technical consumer to quickly and dynamically see input and output parameter lists and HTML5 results sets for Db2 for i stored procedures.  The HTML5 makes for good aesthetics with dynamic sizing and formatting of lengthy column headings and data elements.  Metadata is interpreted real time, so changes made to a parameter list or output result set in a separate session of ACS are detected immediately.  Dynamic row filtering on top of the result set is also available for prototyping WHERE clause enhancements. 

When you consider the other features within this offering, it makes it a contender as your best development tool for prototyping Db2 for i stored procedures regardless of whether they will be consumed by a .NET programming language in a web, client-server or hybrid environment or by a native IBM i programming language.  The less capable the language or the UI integration, the more this tool makes sense. 

Between the .NET Framework and c#, null is supported as a parameter value in this environment, and our tool lets you indicate a null input parameter via entry of the keyword "*null".  Add-On 1 also features increased modularity in the c# code-behind. 

Add-On 2 is Gen Db2 for i Stored Procedures and OO Wrapper Source.  It allows gen of complete IBM SQL PL stored procedures and c# and SQL PL stubs and snippets.  While you'll still have to compile the stored procedures somewhere (like ACS), Add-On 2 is a true development tool. 

This product goes a long way with helping you to develop your own problem-solving technique, because there are so many examples, stubs and snippets generated with each SQL or stored procedure used as basis input... 

Nicely-formatted SQL column headings with spaces are supported (which requires differences in syntax).  Please see pictures of example output for Add-On 2 in these pages. 

Add-On 2 is also intended to help you with the mundane and repetitive tasks like formulating lengthy column subset lists from JOIN SQL statements, or building or enhancing views, join record formats and stored procedures from inline SQL.  Column attributes are pulled from Db2 metadata.  Duplicate columns formed from blanket SQL select statements are resolved with the same pattern that is used to populate the gridview UI element.  This tool will help you save a lot of whittling with minutia level DDS versus SQL syntax differences, so you can make incremental improvements in your application development that take advantage of the strengths of each of the techniques (without requiring a big leap of faith or investment just to get started at a professional level).   

With your purchase, you'll receive all of the c# code-behind source that does the work behind the scenes to set up the SQL and stored procedure requests and that operates the web pages.  Along with all of the XHTML and CSS used for the views... 

Bootstrap or Not - No Biggie
There is a duplicate of the base and Add-On 1 web pages that operates within the responsive-bootstrap-master page strategy, since bootstrap is a part of the web application .NET Framework project template supplied in Visual Studio and you can deploy Add-On 1 for users...  See Chapter 7 picture below...  The reason we offer it as a duplicate is to accomodate your current shop's strategy and to enable you to easily isolate the differences.  But it turns out that tweaking some of the CSS properties in a generic run-time gridview is a bit of a hassle when using bootstrap because you have to get to the required level of specificity for the properties to take...  Anyway, what you might need is in there.

While this particular Db2 data provider from IBM is dependent upon the Microsoft .NET Framework, this often enables top-notch leveraging of both .NET Framework features (web and infrastructure) and IBM Db2 within your programming language, so as a developer, you get lots of power at your disposal.

The Add-On-1 component is generic test harness for IBM SQL PL stored procedures, with soft-coded parameter handling.  The work is done via a single c# .aspx web page, c# code-behind, a couple of classes and the data provider.  The default presentation of Add-On-1 in v2.1 is no longer implemented within a responsive master page so you can expand to get giant width over multiple monitors on the destop based on data at run-time.
