select a.TABLE_NAME,a.COLUMN_NAME,a.DATA_TYPE,

       (CASE a.DATA_TYPE when 'int' then 'limited between -2147483648 and 2147483647'

                      when 'bigint' then 'limited between -9223372036854775808 and 9223372036854775807'

where COLUMNPROPERTY(object_id(a.TABLE_SCHEMA+'.'+a.TABLE_NAME), a.COLUMN_NAME, 'IsIdentity') = 1
