I have a database table that contains column data like this:
Data (field name)
1111,44,666,77
22,55,76,54
32,31,56
I realise this is a very poor design because it is not normalised (I didn't design it - I inherited it). Is there a query that will return the data like this:
1111
44
666
77
22
55
76
54
32
31
56
I am use to using CHARINDEX and SUBSTRING, but I cannot think of a way of doing this as the number of elements in each cell (delimited by a comma) is unknown.
