I currently have a table Telephone it has entries like the following:
9073456789101
+773456789101
0773456789101
What I want to do is remove only the 9 from the start of all the entries that have a 9 there but leave the others as they are.
any help would be greatly appreciated.

The TRIM() function removes the space character OR other specified characters from the start or end of a string. By default, the TRIM() function removes leading and trailing spaces from a string. Note: Also look at the LTRIM() and RTRIM() functions.
To delete the first character from a string, you can use either the REPLACE function or a combination of RIGHT and LEN functions. Here, we simply take 1 character from the first position and replace it with an empty string ("").
Replace function – using Replace function you can remove a special character from a database filed. This function only replaces a single special character.
While all other answer are probably also working, I'd suggest to try and use STUFF function to easily replace a part of the string.
UPDATE Telephone
SET number = STUFF(number,1,1,'')
WHERE number LIKE '9%'
