Linked Server....

Well today, I started the fun filled adventure of managing data from/to a LinkedServer.

During this learning curve, I found plenty of information about how to query from and instert into a Linked server but most of them utilized the OpenQuery TSQL Statement to operate.

One failure of the concepts is to use the inline statement to access the Linked Server.

In my situation, i was linking to a MySQL database offsite.  Below you will find the MSSQL statement patterns to used when utilizing query statements against the Linked Server.

Select:
1:  Select {cols}  
2:  From {LinkedServer}...{table}  
3:  [Conditions]

Insert:
1:  Insert Into {LinkedServer}...{table} [cols,...]  
2:  Values ([cols,...])

There are more commands you can use but the point is that the developer/dba is utilizing only the 'server' and 'table' portions of the source information.  This being, as described by Microsoft, as '{server}.{database}.{schema}.{table}' is simply '{linkedserver}...{table}'.  At least for MySQL, they do not broadcast schema information through general access this is mostly handled by the login credentials instead, as i understand the framework.

In summary, instead of building god-aweful string concatenations with double/triple/etc single quotes to try and get the Execute style expression to execute against the remote server, just use the dot system already in place.  Will allow you to operate on the database/tables in the same way as you maybe/are comfortable with.

SysInternals - BgInfo for ALL Users

Image
I have seen various sites that have been pretty good at getting close to the point of getting Background Information created by the tool BgInfo but none of them have actually solved my specific problem. Solutions currently out there include: Placing into the "All Users" folder This did not work for me, as our implementation does not contain an "All Users" folder in the "Users" folder for profiles. Reg-Hacking and HKCU or HKLM entry This is the worst of all the bad choices available.  I am experienced with Registry Editing and I still would not want or find a need to do this. Placing into the "Default" folder This is good going forward but what about those 20+ user profiles that are already logged in.  FYI, if your server has 20+ user account profiles in the "Users" directory you have larger problems than I am willing to assist with in this posting. The solution that worked for me, will be described below in pain-staki

JSON/AJAX Helpers

Recently, had an implementation where I needed to implement ASP.Net Web API 2 and accompanied it with Javascript/JQuery AJAX communication.  In doing this i found myself making the same pattern calls with some varying value for certain properties for the AJAX data calls.  As such, i ended up building a few helper functions to simply the inclusion of these various minor quirks based on what was needed.  Below  you will find the various forms. 1: /********************************************************************* 2: @type - dataType, such as 'json', 'xml', 'script', 'jsonp' or 'html' 3: @contentType - string value, represents the HTML type of content 4: IE: 'application/json; charset=utf-8' 5: @url - API URL, such as 'api/tasks' should be constrainted to the 6: Web API Controller 7: @success - Function(data, status, xhr) handler, The logic to execute 8: on a 200 res

Acquiring List of controls - Classic JS

Recently ran into a scenario where I need to use the low-level JavaScript parser, instead of JQuery.  During this venture, I ran across a situation where it would be easier for me to select all the HTML Elements with an ID, assign it to a variable as JSON, and then operate on it from that point. So using my previous short-hand experience with JQuery, I started constructing a similar type of format to be used. *********** JQuery *************** // One line and your done, pretty much var cntrls = $('[id]') // Later on, you simply access the element from the variable var val = cntrls['someID'].value *********** JavaScript *********** // Not so one-liner; put in the DOM.Ready event for JS var cntrlIDs = {} var root = document.getElementById('rootID').querySelectorAll('*'); for (i = 0, n = root.length; i < n; ++i) { var el = root[i]; if (el.id) { cntrlIDs[el.id] = el; } } // Later
