Question

I want to ask a question about the SQL. I have the following table.

Name Phone
 a    1
 b    2
 c    3
 d    4
 e    5

I have an ArrayList(java) which contains the [a,b,c,d,e]. Is it possible to put the ArrayList into the mySQL statement to retrieve the all the phone numbers? Thank you.

Answer 1

You could create an IN clause for all the names and map the result set to your data:

SELECT Name, Phone FROM Numbers WHERE Name IN ('a','b','c','d','e')

I’m sure there are already libraries that do the needed work for you. You could start at http://www.hibernate.org/ with your research.
