Left pad varchar to certain length in sql server

Question

I want to left pad int number with 12 digits as 0 and starting with character as 'P'

Eg if number is 345 Then output should be ' P00000000345 '

My Code :

Declare @a int
Set @a =8756
Select Right('P00000000000' +Cast(@a As Varchar(11)),12)

DB : SQL SERVER 2008

Answer 1

Try

Declare @a int
Set @a =8756
Select 'P'+Right('00000000000' +Cast(@a As Varchar(11)),11)

Answer 2

You're mostly correct, but should apply the P as a separate step:

Declare @a int
Set @a =8756
Select 'P' + Right('000000000000' +Cast(@a As Varchar(11)),12)

Answer 3

Try this

Declare @a int
Set @a =8756
Select 'P' + REPLACE(STR(@a, 11), SPACE(1), '0')

Change

Select Right('P00000000000' +Cast(@a As Varchar(11)),12)

to

Select 'P' + Right('00000000000' +Cast(@a As Varchar(11)),11)
