How to retrieve a set of table data in SQL?

I want to ask a question about the 开发者_JS百科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.

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.

I don't think there is a direct way to do this.
But you have the following options:

1. You can use the IN clause. Create the IN clause dynamically by looping over the list and creating a string. Note: Oracle limits the number of entries in the IN clause to 1000.

2. You can insert the values into a (temp) table and use this table in your SQL, in a IN clause or as a JOIN (I prefer the join)

3. You can have a PL/SQL stored procedure that takes in a (oracle) Array as parameter. And loop through this array in the stored proc. See this for an example.

you have to create your own statement per java. iterate over the arraylist and add every string element to the statement.
