Teradata中的日期转换

Question

I am using this query select * from temp where cast (DateStart as varchar(12))

so if we count this for today it should give records with date less than '2014-07-17'

but the above query is giving all records even the records with date greater than the above given date.

datatype datestart : varchar(10)

how can I convert above to give records only less than the calculated date? thanks.

Answer 1

i got a solution for this it was converting all date like 1914 instead of 2014 and that is why returning all records. So solution is : cast ( DateStarted as date format 'mm/dd/yy') + INTERVAL '100' YEAR
