sql add zeros in front of number

Right function can be use to perform this formatting.For example - if we have table with
column containing numbers and we have to add leading zeros to these number we can do following:
 
SELECT * FROM Numbers;
Num
12
112
12
122
122

5 row(s) affected.

Formatting:
SELECT RIGHT('00000'+ CONVERT(VARCHAR,Num),6) AS NUM FROM Numbers;

NUM
000012
000112
000012
000122
000122
5 row(s) affected.


text templates c#

This is simple implementation of search/replace template engine in c#
Template class is following:
  
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Collections;
using System.Xml.Linq;
using System.Linq;

public class Templates
{

private Hashtable templates;
public Templates(string templatesFilePath)
{

templates = new Hashtable();
System.IO.StreamReader confFile = new System.IO.StreamReader(templatesFilePath);
XDocument configuration =XDocument.Parse(confFile.ReadToEnd());
var tpls = from cs in configuration.Descendants("Template")
select cs;
foreach (var t in tpls)
{
templates.Add(t.Attribute("Name").Value,t.Value);
}

}

/// <summary>
/// REnder templates with
/// </summary>
/// <param name="templateName"></param>
/// <param name="values"></param>
/// <returns></returns>
public string Render(string templateName, params string[] values)
{
Hashtable hash = new Hashtable();

for (int i = 0; i <= Math.Floor((decimal)values.Length/2); i+=2)
{
hash.Add(values[i], values[i + 1]);
}
return Render(templateName, hash);
}

/// <summary>
/// Renders
/// </summary>
/// <param name="templateName"></param>
/// <param name="values"></param>
/// <returns></returns>
public string Render(string templateName,Hashtable values)
{
string result = String.Empty;
if (templates.ContainsKey(templateName))
{
string template = (string)templates[templateName];
foreach (DictionaryEntry entry in values)
{
template = template.Replace("{$" + entry.Key + "}", "" + entry.Value);
}
result = template;
} else {

}
return result;
}

}


Sample template file will be looking like this:
 
<Templates>
<Template Name="template1">
<![CDATA[
My first template with {$Value1}
and {$Value2}
]]>
</Template>

<Template Name="template2">
<![CDATA[
My second template with {$Value3} and {$Value4}
]]>
</Template>
</Templates>



And code for calling this awesome template engine will be following:
 
Templates templates = new Templates(ConfigManager.AssemblyDirectory + @"\MyTemplates.xml");
var result=templates.Render("template1", "Value1", Aome Value1, "Value2", DateTime.Now.ToString("yyyy-MM-ddThh:mm:ss")));
