Parameterized insertion of data in HANA through JavaScript

Hi there,

I created a little JavaScript application, that calculates different solutions to an optimization problem. At the end of each run I would like to store the solutions in a table on a HANA instance.

So far I tried to apply the code according to this example: How to insert data in HANA through JavaScript (with XS Engine)

My code with sample values:

var conn = $.db.getConnection();

var st = conn.prepareStatement("INSERT INTO \"SCHEMA\".\"testTable\" values(131,'E')");

st.execute(); 

conn.commit();

conn.close();

Standing alone in its own .xsjs file this code snippet performs perfectly well and the values are added to the table.

However, it doesn't work with parameterized insertion:

var st = conn.prepareStatement("INSERT INTO \"SCHEMA\".\"testTable\" values(?,?)");

st.setString(1,id);

st.setString(2,val1);

Do you have any ideas how I could include a parameterized insertion in the application to write e.g. the values stored in an array to the table?

I hope u can help me and many thanks in advance,

Daniel
