I've noticed different Internal name for same List column in 2 different site collection .For example i've list column- ParameterList Name in Site Collection1 and i see internal name as Parameter%5Fx0020%5FListName for the same list column .But on Site collection 2 i see internal name as ParameterList%5Fx0020%5FName for the same List column.Same List exists in both site collection . My client CAML query code breaks due to diference in Internal Name for the specified List column.I work in SP2010
Does any one have idea why this is happenning?
