SQL Script To Generate C# Model

While working on a data migration project that uses C# and Azure Functions.  I found myself in the need to generate a model of the table(s).  While doing a Google search I came across the following blog post that has a script to generate the model properties for me.  Simply replace the table name variable at the top of the script with the table name you want to generate the properties for.  You may also need to include the schema name in the table name if you have multiple tables with the same name, just under different schema's.  I did make one change to it in the select @ result line.  It was adding a blank line in between each property, so I removed the new line.


 declare @TableName sysname = 'TABLE_NAME'  
 declare @Result varchar(max) = 'public class ' + @TableName + '  
 {'  
 select @Result = @Result + '  
   public ' + (CASE WHEN ColumnName = 'RowVersion' THEN 'byte[]' ELSE ColumnType END) + NullableSign + ' ' + ColumnName + ' { get; set; }'  
 from  
 (  
   select   
     replace(col.name, ' ', '_') ColumnName,  
     column_id ColumnId,  
     case typ.name   
       when 'bigint' then 'long'  
       when 'binary' then 'byte[]'  
       when 'bit' then 'bool'  
       when 'char' then 'string'  
       when 'date' then 'DateTime'  
       when 'datetime' then 'DateTime'  
       when 'datetime2' then 'DateTime'  
       when 'datetimeoffset' then 'DateTimeOffset'  
       when 'decimal' then 'decimal'  
       when 'float' then 'float'  
       when 'image' then 'byte[]'  
       when 'int' then 'int'  
       when 'money' then 'decimal'  
       when 'nchar' then 'string'  
       when 'ntext' then 'string'  
       when 'numeric' then 'decimal'  
       when 'nvarchar' then 'string'  
       when 'real' then 'double'  
       when 'smalldatetime' then 'DateTime'  
       when 'smallint' then 'short'  
       when 'smallmoney' then 'decimal'  
       when 'text' then 'string'  
       when 'time' then 'TimeSpan'  
       when 'timestamp' then 'timestamp'  
       when 'rowversion' then 'byte[]'  
       when 'tinyint' then 'byte'  
       when 'uniqueidentifier' then 'Guid'  
       when 'varbinary' then 'byte[]'  
       when 'varchar' then 'string'  
       else 'UNKNOWN_' + typ.name  
     end ColumnType,  
     case   
       when col.is_nullable = 1 and typ.name in ('bigint', 'bit', 'date', 'datetime', 'datetime2', 'datetimeoffset', 'decimal', 'float', 'int', 'money', 'numeric', 'real', 'smalldatetime', 'smallint', 'smallmoney', 'time', 'tinyint', 'uniqueidentifier')   
       then '?'   
       else ''   
     end NullableSign  
   from sys.columns col  
     join sys.types typ on  
       col.system_type_id = typ.system_type_id AND col.user_type_id = typ.user_type_id  
   where object_id = object_id(@TableName)  
 ) t  
 order by ColumnId  
 set @Result = @Result + '

 print @Result

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

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

Navigating Microsoft Dynamics 365 Customization: Plugins vs. Azure Functions

Embarking on the Microsoft Dynamics 365 customization journey offers numerous opportunities to enhance your business processes. However, deciding between the available options, such as Plugins and Azure Functions, can be challenging. This engaging post will serve as your trusty guide, helping you choose the best option for your Dynamics 365 customization needs! The Two Customization Pathfinders: Plugin and Azure Function The Agile Plugin 🏃‍♂️ Reference: Microsoft Docs - Write a plug-in Plugins are like the swift trail runners of the Dynamics 365 customization world. They're the go-to choice for quick, real-time (synchronous), or background (asynchronous) operations that occur within the platform. They can intercept events and modify data before it's saved or displayed to the user. Choose Plugins when: You need real-time processing (synchronous) or background processing (asynchronous). You want to ensure data integrity. You need tight integration with Dynamics 365. Plugins mig
