Subject Re: Schema question : Query to support "Find which all of these 500 email ids have been registered"
Date Fri, 27 Jul 2012 08:49:19 GMT
What about if I spread these columns across 20 rows ? Then I have to
query each of these 20 rows for 500 columns. but still this seems a
better solution than one row for all cols or separate row for each
email id approaches !?
