Usage of convert conversion functions in SQL

How to Use convert:

//////////////////////////////////////// //////////////////////////////////////// ////////

Format:
Convert (data_type, expression [, style])

Note:
This style is generally in the time type (datetime, smalldatetime) and string type (nchar, nvarchar, Char, varchar)
It is used only when they are converted to each other.

Example:
Select convert (varchar (30), getdate (), 101) now
Result:
Now
---------------------------------------
09/15/2001

//////////////////////////////////////// //////////////////////////////////////// /////

The meaning of the style number in the conversion time is as follows:

Bytes -------------------------------------------------------------------------------------------------
Style (2 bits represent the year) | style (4 bits represent the year) | input/output format
Bytes -------------------------------------------------------------------------------------------------
-| 0 or 100 | mon dd yyyy hh: miam (or pm)
Bytes -------------------------------------------------------------------------------------------------
1 | 101 | mm/DD/yy

2 | 102 | YY-mm-dd
Bytes -------------------------------------------------------------------------------------------------
3 | 103 | dd/mm/yy
Bytes -------------------------------------------------------------------------------------------------
4 | 104 | DD-mm-yy
