Passing array of timestamps into oracle stored proc

Question

Hey there,
I have an interesting problem. I need to pass an array of java.sql.Timestamp into a stored proc.
I see that the PreparedStatement provides a setArray() method which takes as arguments an int, java.sql.Array
Anybody know how I can use the java.sql.Array to my advantage here ? Basically, I don't see how I can create a java.sql.Array of Timestamps
thanks in advance for all your help.

The java.sql.Array implementation is provided by your jdbc driver.
For exemple using Oracle you can obtain an sql.Array with something like this :
Connection con=getConnection() // get a connection to the DB
//first declare what type of array you will use in the DB
// you probably want to replace CHAR(7) by Timestamp here
PreparedStatement createArray=
con.prepareStatement("CREATE OR REPLACE TYPE MYARRAY AS VARRAY(100) OF CHAR(7)");
createArray.execute();          
//then get an java instance of this Array
oracle.sql.ArrayDescriptor arrayDescriptor = oracle.sql.ArrayDescriptor.createDescriptor("MYARRAY",con);
// content is used to fill the Array
String[] content= {"string0", "string1"};
java.sql.Array sqlArray=new oracle.sql.ARRAY(arrayDescriptor, con, content);               
// then call your stored procedure
java.sql.CallableStatement callStmt=con.prepareCall("call MyStoredProcedure(?)");
// passing the array as an argument
callStmt.setArray(1,sqlArray);
callStmt.execute();
As you can see the code is quite database specific.
hope that helps.
