select case a.xtype
when 167 then 'SUM(LEN('+a.name+')) as sum_len_'+a.name+','
when 175 then 'SUM(LEN('+a.name+')) as sum_len_'+a.name+','
when 231 then 'SUM(LEN('+a.name+')) as sum_len_'+a.name+','
when 106 then 'SUM('+a.name+') as sum_'+a.name+','
when 56 then 'SUM('+a.name+') as sum_'+a.name+','
when 104 then 'SUM(CONVERT(int,'+a.name+')) as sum_'+a.name+','
when 61 then 'SUM(MONTH('+a.name+')+DAY('+a.name+')+YEAR('+a.name+')) as sum_'+a.name+',
SUM(LEN(MONTH('+a.name+'))+LEN(DAY('+a.name+'))+LEN(YEAR('+a.name+'))) as sum_len_'+a.name+',' -- datetime
else a.name+' '+convert(varchar,a.xtype)
end col_type
