Variable-length non-Unicode data with a maximum of 8,000 characters. Storage size is the actual length of the data entered, not n bytes. The data entered can be 0 characters in length. Use char when the data entries in a column are expected to be consistently close to the same size. Use varchar when the data entries in a column are expected to vary considerably in size
