Most efficient T-SQL way to pad a varchar on the left to a certain length?

I have the customer table where the customerID is of length:10
but there are few customer where the length is 3 or 5

ex: 
3445
34
789
7800

but the output should be like the following, I need to prefix zero here if length is less than 10

0000003445
0000000034
0000000789
0000007800

Script to get this data is:

select customerID from customer

Try the following code:

Since you are using sql server 2008, you could use replicate function to add zeros to the value..

Select ltrim(right(replicate(0,10) + <column>,10)) 
from your_table
