trim left characters in sql server?

Question

I want to write a sql statement to trim a string 'Hello' from the string "Hello World'. Please suggest.

Answer 1

To remove the left-most word, you'll need to use either RIGHT or SUBSTRING. Assuming you know how many characters are involved, that would look either of the following:

SELECT RIGHT('Hello World', 5)
SELECT SUBSTRING('Hello World', 6, 100)

If you don't know how many characters that first word has, you'll need to find out using CHARINDEX, then substitute that value back into SUBSTRING:

SELECT SUBSTRING('Hello World', CHARINDEX(' ', 'Hello World') + 1, 100)

This finds the position of the first space, then takes the remaining characters to the right.
