Using spt_values to generate junk datas

master..spt_values can be used if you need to populate a table with 100 numbers from 1,or if you need to generate some Junk/Test data.Refer the query below that will generate data of various datatypes

select
abs(checksum(newid()))%10000 as n_id,
abs(checksum(newid()))*rand()/10000 as f_float,
substring(replace(cast(newid() as varchar(36)),'-',''),1,abs(checksum(newid()))%15) as s_string,
dateadd(day,0,abs(checksum(newid()))%100000) as d_date,
abs(checksum(newid()))%2 as b_byte
from master..spt_values
where type='p' and number between 1 and 200
