Konvertera dina listor till en flerdimensionell array och sedan kan du göra något som:
Oracle-inställningar :
CREATE TYPE stringlist AS TABLE OF VARCHAR2(100);
/
CREATE TYPE stringlist_list AS TABLE OF stringlist;
/
CREATE TYPE stringlist_list_list AS TABLE OF stringlist_list;
/
CREATE PROCEDURE load_list (
in_list IN stringlist_list_list
)
AS
BEGIN
NULL; -- Do something with the list
END;
/
Java :
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.CallableStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import oracle.jdbc.OracleCallableStatement;
import oracle.sql.ARRAY;
import oracle.sql.ArrayDescriptor;
public class TestDatabase2 {
public static void main(String args[]){
try{
Class.forName("oracle.jdbc.OracleDriver");
Connection con = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:XE","username","password");
// Convert your lists to arrays using #toArray( T[] )
String[] l1 = { "Math", "Physics" };
String[] l2 = { "English", "Spanish" };
String[] l3 = { "French", "German" };
ArrayDescriptor des = ArrayDescriptor.createDescriptor("STRINGLIST_LIST_LIST", con);
ARRAY school = new ARRAY( des, con, newString[][][]{
new String[][]{ l1, l3 },
new String[][]{ l2, l3 }
} );
CallableStatement st = con.prepareCall("{ call add_school( :school )}");
// Passing an array to the procedure -
((OracleCallableStatement) st).setARRAYAtName( "school", school );
st.execute();
} catch(ClassNotFoundException | SQLException e) {
System.out.println(e);
}
}
}
