SQL Script to Create Enums For Table Columns

While working on a data migration project, using C# and Azure Functions, I found myself needing to create enums to use in my code for the columns.  Some of the tables where vary large (over 200 columns) and doing this manually would have taken a while to do it.  So, I wrote the below SQL script to create the enums for me.  To use this simply replace the table and schema variables with the schema and table name you want to generate the enums for.


 declare @Table sysname = '<INSERT TABLE NAME HERE>';  
 declare @Schema sysname = 'INSERT SCHEMA NAME HERE';  
 declare @Result varchar(max) = 'public enum ' + @Table + 'Columns' + '  
 {'  
 select @Result = CONCAT(@Result, '  
      ',ColName, ' = ', SUM(ColNum), ',')  
 from  
 (  
      select COLUMN_NAME as ColName, SUM(ORDINAL_POSITION - 1) as ColNum  
      from INFORMATION_SCHEMA.COLUMNS  
      where TABLE_NAME = @Table AND TABLE_SCHEMA = @Schema  
      group by COLUMN_NAME  
 ) t  
 group by ColName, ColNum  
 order by ColNum  
 set @Result = @Result + '  
 }'  
 print @Result

Dynamics Set IFrame URL - D365 v8 vs. D365 v9

While doing client work, I came across a problem with setting an IFrame URL dynamically.  The underlying issue was that the sandbox instance is on v8 of Dynamics 365 and production is on v9 of Dynamics 365.  The reason for this was because this client was setup around the time that Microsoft rolled out v9.  Anyways, JavaScript that I wrote to dynamically set the URL of the IFrame wasn't working in the v9 instance.  This was because of changes that Microsoft made to how IFrames are loaded on the form and also changes to JavaScript. Here is my v8 setup: JavaScript runs OnLoad of contact form.  This works because of how IFrames are loaded in v8.  You can also run it on either a tab change (hide / show) or OnReadyStateComplete event of the IFrame.  Depending on your setup you will need to choose which is best for you.  For me in this case it was the OnLoad event. Here is the JavaScript: function OnLoad() { //Get memberid var value = Xrm.Page.data.entity.attri

Validating User Input In CRM Portals With JavaScript

When we are setting up CRM Portals to allow customers to update their information, open cases, fill out an applications, etc. We want to make sure that we are validating their input before it is committed to CRM.  This way we ensure that our data is clean and meaningful to us and the customer. CRM Portals already has a lot validation checks built into it. But, on occasion we need to add our own.  To do this we will use JavaScript to run the validation and also to output a message to the user to tell them there is an issue they need to fix. Before we can do any JavaScript, we need to check and see if we are using JavaScript on an Entity Form or Web Page.  This is because the JavaScript, while similar, will be different.  First, we will go over the JavaScript for Entity Forms.  Then, we will go over the JavaScript for Web Pages.  Finally, we will look at the notification JavaScript. Entity Form: if (window.jQuery) { (function ($) { if (typeof (entityFormClientVali

CRM Portals OnChange Event For DateTime

Occasionally when working with CRM Portals you may run into the need to get the OnChange event for a date time field.  Because of the way that CRM Portals renders date time fields this is slightly more complicated then working with text boxes, check boxes and pick lists.  During my process I ended up reaching out to Microsoft for help on this and below are the steps they provided to help me with this problem: 1) Click on the date time control 2) Press F12 3) In console type $('div.control') and hit enter (this will give you a list of div controls) 4) Locate the div control for the date time field 5) Go to the entity form or web page in CRM and add the following code snippet (replace the 2 with the number your div control is located at): 1: $(document).ready(function () 2: { 3: var dpcontrol = $('div.control')[2]; 4: $(dpcontrol).on("dp.change", function (e) 5: { 6: alert("On chang
