Reformatting Phone Numbers in MSSQL

HI Experts,

I have a MSSQL table that has a varchar field for phone numbers, which are formatted as 4161234567.

I am looking to change these to the (416) 123-4567 and save them in the same field via UPDATE. So, I am wondering if within an update query I can do a SELECT and create 3 variables, then concatenate the 3 variables.

Thank you

Run this in SSMS to verify that it does what you expect..
Declare @phone varchar(10) = '4161234567'
SELECT '(' + LEFT(@phone, 3) + ') ' + SUBSTRING(@phone, 4, 3) + '-' + RIGHT(@phone, 4) as phone

Open in new window

Then here's the UPDATE (rename the obvious)
UPDATE your_table
SET '(' + LEFT(phone_number, 3) + ') ' + SUBSTRING(phone_number, 4, 3) + '-' + RIGHT(phone_number, 4)

Open in new window


>and save them in the same field via UPDATE
I recommend instead of the UPDATE just leaving the column the way it is now, and just use the above functions in a SELECT to cosmetically display the data correctly.   At least that way you can do a quality check on the column in that it's a ten-digit number.
