T-SQL: Adding Leading Zeros with a Simple Scalar Function

We were creating a extract at work from T-SQL and new that the we would need to export data with leading zeros. The data was not stored in the database with those leading zero values. The solution, create a simple scalar function to dynamically add the zeros that could accept two parameters ( text , and total length).

The Function is rather simple takes the total length value passed by the user and then subtracts the Length of the the text value.

What would make this better?

  • Would have a default value for total length
  • Error checking to make sure the text supplied is not longer than the total length

T-SQL Create a View for Report Date Ranges by Month

The below example gives prior and current month first and last day values.The code below dynamically formats the date to give you date range values for reporting:

[LFM-FirstDay] – First Day of thePrior Month or Last Full Month First Day,
[LFM-LastDay] – 11:59 PM of the last day of the prior month,
[CM-FirstDay] – Current Month First Day and
[CM-LastDay] – 11:59 PM of the last day of the Current month.

USE [dbofchoice]
CREATE VIEW [DBO].[ReportDates]
DATEADD(month, -1 ,DATEADD(month, DATEDIFF(month, 0, GETDATE()), 0))
as [LFM-FirstDay]
,DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,getdate()),0))
as [LFM-LastDay]
,DATEADD(mm, DATEDIFF(m,0,getdate()),0)
as [CM-FirstDay]
,DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,getdate())+1,0))
as [CM-LastDay]

C# – Calculating Distance between Zipcodes

Calculating the distance between ZIP codes has become a common feature in search engines. For instance, if you’re searching for restaurants, a Web site will often allow you to enter a ZIP code and display all of the restaurants within X miles of that ZIP code. Here is one way application developers to implement a ZIP code distance calculator using the .NET Framework and C#.

This article uses a derivation of the Haversine formula to calculate the distance between ZIP codes. The Haversine formula is used to determine the distance between two points on a sphere – in this case the earth. While this isn’t 100 percent accurate due to the earth not being a perfect sphere, it is probably as close as you’re going to get without getting out the tape measure!
