I'm facing problem in writing a sql query that will select a sub-string in a string. There is a column in table called description and its data type is nvarchar(50). It holds values like
XXX,C700,1 1/2,XXXXXXXX,10 CU.FT.
and I need to select the size part of the string, for eg 3/4 or 1 1/2. I see pattern in the values, the size part always comes after the second , (comma) in the string. Can you please suggest me a sql that will select only that part.
