Well in my case here,s what I did
I used a select statement
var ID=1;// set to 1 because in needed to use it for the next ID , this is not safe but just for fun
var conn = $.db.getConnection();
conn.prepareStatement("SET SCHEMA \"SYSTEM\"").execute();
//get ID
var pstmt = conn.prepareStatement(
"select * from \"SYSTEM\".\"MYTABLE\""
);
var rs = pstmt.executeQuery();
if(!rs.next())
{
body = "Failed Reteiving attribute view";
$.response.addBody(body);
}
else{
while (rs.next())
{
ID++;
}
}
.......
So you the ID value you can print out by attaching to a body tag or however you deem fit
