SQL Server Script to Check to See if a Database has Reached a Certain Capacity

Here’s a stored procedure I developed years ago to see if a database has reached a certain capacity (basically to check if it was full) and returns “true” if it has exceeded that capacity.

CREATE PROCEDURE [dbo].[IsDatabaseFull]
AS
BEGIN
	DECLARE @CurrentSizeMB int
	DECLARE @MaxSizeMB int
	DECLARE @PercentageFull int
	SET NOCOUNT ON
	SET @PercentageFull = 0.10 /* Change this value */
	SELECT @CurrentSizeMB = size*8/1024,
		   @MaxSizeMB = max_size*8/1024
	FROM sys.database_files
	WHERE [file_id] = 1
	IF @CurrentSizeMB >= (@MaxSizeMB * @PercentageFull)
		RETURN 1 /* True */
	ELSE
		RETURN 0 /* False */
END

In the example above, the capacity is set to 10% of the maximum size of the database.  By changing the capacity to 90%-95% and combining it with an email script, it can used to send notifications to you prior to a database becoming full so that you can increase its size preemptively.

Capitalizing the First Letter in All Keys of a JSON Object using C#

It took me some time to get this right, drawing from discussions on StackOverflow, but here is code that will capitalize the first letter of every key in a JSON object.

public static JObject Capitalize(JObject obj)
{
  JObject newObj = new JObject();
  foreach (var o in obj)
    {
      string key = o.Key;
      string newKey = char.ToUpper(key[0]) + key.Substring(1);
      JToken value = o.Value;
      if (value.HasValues)
      {
        try
        {
          JObject child = JObject.Parse(value.ToString());
          JObject newValue = Capitalize(child);
          value = newValue;
        }
        catch (Exception)
        {
        }
      }
      newObj[newKey] = value;
    }
  return newObj;
}

Implementing a 410 Status Code Using C#

Here’s how you can setup a 410 Status Code using C#.  Just place this code in the code-behind file in the Page_Load event handler, replacing www.domain_name.com with your domain name, of course:

Response.StatusCode = 410;
if (Request.ServerVariables["SERVER_NAME"].ToString().ToLower() == "www.domain_name.com");
Response.Write("410 Gone");
