Sub Add_My_Index()
    Dim K As Long
    On Error Resume Next
    Application.DisplayAlerts = False

'Deleting an old Index if it already exist with the Name<MY_INDEX>
    Application.DisplayAlerts = True
    On Error GoTo 0
'Adding an Index tab in ThisWorkbook with the Name<MY_INDEX>
    ThisWorkbook.Sheets.Add Before:=ThisWorkbook.Worksheets(1)
    ActiveSheet.Name = "MY_INDEX"
    ThisWorkbook.Sheets("MY_INDEX").Cells(1, 1) = "INDEX"
'Adding and formatting the Index title in <MY_INDEX> Tab
    With Selection.Interior
        .Pattern = xlSolid
        .PatternColorIndex = xlAutomatic
        .ThemeColor = xlThemeColorLight1
        .TintAndShade = 0.349986266670736
        .PatternTintAndShade = 0
    End With

        .TintAndShade = 0
        .ThemeFont = xlThemeFontMinor
    End With
    ActiveCell.ColumnWidth = 35
'Looping through other than <MY_INDEX> tab to add <Back to Index> Button.
For K = 2 To Sheets.Count
    ActiveSheet.Cells(K, 1).Select
    ActiveSheet.Hyperlinks.Add _
    Anchor:=ActiveSheet.Cells(K, 1), Address:="", _
    SubAddress:="'" & Sheets(K).Name & "'!A1", TextToDisplay:=Sheets(K).Name
If Sheets(K).Name = "INDEX" Then GoTo NxtSht
   ActiveSheet.Rows("1:1").RowHeight = 30.75
   ActiveSheet.Columns("A:A").ColumnWidth = 16.29

'Adding < Back to Index > button in Other tabs
   ActiveSheet.Shapes.AddShape(msoShapeRoundedRectangle, 1.5, 2.25, 85.5,25.5).Select
   Selection.ShapeRange.ShapeStyle = msoShapeStylePreset31
   Selection.Placement = xlFreeFloating
'Renaming <Shape Name> and Storing the Name in a Variable
   Selection.ShapeRange.Name = "Back2Index"
   Z = Selection.ShapeRange.Name
'Adding the Text as <Back to Index> in the Shape
   Selection.ShapeRange(Z).TextFrame2.TextRange.Characters.Text = "Back to Index"

   With Selection.ShapeRange(1).TextFrame2.TextRange.Characters(1, 13). _
        .FirstLineIndent = 0
        .Alignment = msoAlignLeft
   End With

'Formatting the Shape Color Themes
   With Selection.ShapeRange(1).TextFrame2.TextRange.Characters(1, 13).Font

How to Create a Backup for Active Workbook with Current Date with Excel Macro

Excel VBA Macro to Create a Back up for Active Workbook with Current Date in Same Location.
Sub Create_Backup()
ActiveWorkbook.SaveCopyAs _
Filename:=ActiveWorkbook.Path & "\" & "BackUp" & "_" & _
Format(Date, "MM-DD-YY") & "_" & ActiveWorkbook.Name
End Sub

In the Same way we can Create a Back up for ThisWorkbook with Current Date as follows :

Sub Create_Backup()
ThisWorkbook.SaveCopyAs _
Filename:=ThisWorkbook.Path & "\" & "BackUp" & "_" & _
Format(Date, "MM-DD-YY") & "_" & ThisWorkbook.Name
End Sub

Tips :
If you want to Save the ActiveWorkbook of different format(97-2003 format) to a desired format(2007 format), use the following file format Codes.

51 = xlOpenXMLWorkbook (2007-2013, xlsx)
52 = xlOpenXMLWorkbookMacroEnabled (Macro Enabled Format in 2007-2013, xlsm)
50 = xlExcel12 (Excel Binary Format in 2007-2013 , xlsb)
56 = xlExcel8 (97-2003 Format to Excel 2007-2013, xls)

ActiveWorkbook.SaveAs "C:\Users\YourUserName\Desktop\YourFileName", Fileformat:=52 

It is always better to use the FileFormat Code Numbers instead of the Defined Constants in the code so that Macro will Compile OK .

Excel 97-2003 may won't understand what is the < xlOpenXMLWorkbookMacroEnabled> Constant is.

Help :
Active Workbook means the Workbook which is Currently Active / on which we are currently working.

This Workbook means the Workbook in which we are writing the Macro code.

How to Insert DEFAULT Constraint Values into a Table in SQL Server

SQL DEFAULT Constraint
The DEFAULT constraint is used to insert a default value into a column.
The default value will be added to all new records, if no other value is specified.

When a Field is declared as DEFAULT , it will take the default value specified , we no need to insert this value in the INSERT INTO statement.So we have to ignore or skip it.This we can do as follows :

My SQL / SQL Server / Oracle / MS Access:

C_Id int NOT NULL,
LastName varchar(255) NOT NULL,
FirstName varchar(255),
Address varchar(255),
City varchar(255) DEFAULT 'Hyderabad'
Gender varchar(50)

INSERT Statement for Table with DEFAULT Constraint values
When a Field is declared as DEFAULT , it will take the default value specified , we no need to insert this value in the INSERT INTO statement.So we have to ignore or skip it.This we can do as follows :

INSERT INTO Customers values (123,'Excel','Reddy',DEFAULT,'Male')

Here , In the INSERT INTO statement we passed DEFAULT as a value for the DEFAULT Value City.,so that it will take the Default value specified(Hyderabad) in the Table Creation.
