I need to create a derived column that removes the characters to the left of an asterisk.

Example:

5678*12345 would be 12345

Thanks for you help in advance!

PARSENAME is less reliable than th emethod I posted. Both the examples shown below will return inocrrect results if you use parsename
SELECT PARSENAME(REPLACE('abc*x.yz','*','.'),1)
SELECT PARSENAME(REPLACE('abc[d*e]xyz','*','.'),1)
