Removing Duplicate Data from SQL Query Caused by New Line Character

SQL No Comments

We had a query retrieving data from a linked Oracle server. We needed unique rows only. This is the original query: 

SELECT Column
     FROM OPENQUERY( LinkedServer, 'SELECT DISTINCT Column from TABLE;' );

However, this still returned some duplicates despite using DISTINCT. As it turned out, some rows had a new line character in them. The solution:

SELECT distinct replace(replace(Column,CHAR(13),''),CHAR(10),'')
     FROM OPENQUERY( LinkedServer, 'SELECT DISTINCT Column from TABLE;' )

How to Find Column Causing “String or binary data would be truncated” Exception in Entity Framework 5.0.

C# Entity Framework 1 Comment

I recently encountered an issue with Entity Framework when it would throw “String or binary data would be truncated. The statement has been terminated.” Since the query contained close to 80 fields, I needed an easy way to determine the culprit. Since I already had a class which inherits from DbContext, I added suggested try-catch block in my SaveChanges() override method:

public partial class MyContext : DbContext
	{
		public override int SaveChanges()
		{
			try
			{
				return base.SaveChanges();
			}
			catch (DbEntityValidationException ex)
			{
				foreach (var error in ex.EntityValidationErrors)
				{
					Console.WriteLine("====================");
					Console.WriteLine(
						"Entity {0} in state {1} has validation errors:",
						error.Entry.Entity.GetType().Name,
						error.Entry.State);
					foreach (var ve in error.ValidationErrors)
					{
						Console.WriteLine("\tProperty: {0}, Error: {1}", ve.PropertyName, ve.ErrorMessage);
					}
					Console.WriteLine();
				}
				throw;
			}
		}
	}

You have to make sure that you don’t set ValidateOnSaveEnabled to false. It is set to true by default, but sometimes it is useful to disable it to improve performance.

Bootstrap Font Awesome Icons not working on IE9, IE10

Web No Comments

If you are using an older version of Font Awesome you may discover an issue occurring on IE 9 and IE 10, when font is displayed as squares without any text. After some extensive googling the issue was resolved by modifying font-awesome.css and changing the format('eot') to format('embedded-opentype') for the fontawesome-webfont.eot:

from this:

@font-face {
font-family: "FontAwesome";
src: url('../font-awesome/fontawesome-webfont.eot');
src: url('../font-awesome/fontawesome-webfont.eot?#iefix') format('eot'), url('../font-awesome/fontawesome-webfont.woff') format('woff'), url('../font-awesome/fontawesome-webfont.ttf') format('truetype'), url('../font-awesome/fontawesome-webfont.svg#FontAwesome') format('svg');
font-weight: normal;
font-style: normal;
}

to this:

@font-face {
font-family: "FontAwesome";
src: url('../font-awesome/fontawesome-webfont.eot');
src: url('../font-awesome/fontawesome-webfont.eot?#iefix') format('embedded-opentype'), url('../font-awesome/fontawesome-webfont.woff') format('woff'), url('../font-awesome/fontawesome-webfont.ttf') format('truetype'), url('../font-awesome/fontawesome-webfont.svg#FontAwesome') format('svg');
font-weight: normal;
font-style: normal;
}

Even better, you can update to the latest version of Font Awesome, which already has this fix.
