122222200

I need to change these values to:

1955.00
1222222.00

Answer 1

Please Try : select reverse(stuff(reverse(columnName),3,0,'.') ) from yourTable

Answer 2

declare @a varchar(10) = 'aaa' select concat(@a,'.00')

Answer 3

Query:

SELECT col,
       LEFT(col,len(col)-2) + '.' + RIGHT(col,2) as newcol
FROM Table1

Result:

|       COL |     NEWCOL |
|-----------|------------|
|    195500 |    1955.00 |
| 122222200 | 1222222.00 |

Answer 4

Please see the following code. You can choose the symbols and index in variable.

 declare @index int,@sym varchar(10)
 set @sym='#'
 set @index=2
 select left(195500,@index) +''+@sym+''+right(195500,len(195500)-@index) 

Answer 5

try this

Declare @s varchar(50) = '1234567812333445'
Select Stuff(@s, Len(@s)-1, 0, '.')
--> 12345678123334.45
