Multiple sql statements from java

Question

I am executing sql statements in MaxDB 7.6.04.12 from java using jdbc.
I want to execute multiple statements at a time, but it seems that however I separate the statements, I get
com.sap.dbtech.jdbc.exceptions.DatabaseException: [-3014] (at 433): Invalid end of SQL statement
I have tried separating the statements with just a semi-colon, with a semi-colon and new line, with newline-//-newline (as works with SQL Studio), but whatever I try I get this error or some other.
Is it possible to do this? and if so how?
Thanks
Chris

Hi Lars,
Here are the relevant bits of code.
However I'm not sure how helpful that will be - I'm using the SpringFramework for my jdbc calls, as it saves a lot of time and effort, and my calls are to Spring methods, which are wrappers round the base jdbc calls.
I'll post it anyway, just in case you're familiar with Spring. I haven't looked at the Spring code, but my understanding is it pretty much just passes the sql to standard jdbc calls.
I guess my next step would be to trace through the Spring code as it executes and see if anything becomes apparent. However I'm under some time pressure and was hoping to avoid that.
My other alternative is to create non-temporary tables, and drop them explicitly when I've finished with them.
    public Set<String> getPriceUpdatedProducts() {
        final Set<String> prods = new TreeSet<String>();
        String sql;
        int updates;
        // need single connection template so subsequent statements can access temp tables:
        JdbcTemplate jtSingle = getSingleConTemplate(jdbcTemplate);
        // inDCs is a list of dist channels for an sql 'in' statement:
        String inDCs = "";
        for (String siteId: siteConfig.getAllSiteIds()) {
            if (!"".equals(inDCs)) inDCs += ",";
            inDCs += "'" + siteConfig.getSiteIdProperty(siteId, "distChanId") + "'";
        // Clear all the changed flags from the last run:
        updates = jtSingle.update("update zchangedartdc set changed = '' ");
        // Get the current data into a temp table:
        sql = "create table temp.pricechanges as " +
              "select A304.matnr, A304.vtweg, konp.kbetr price " +
              "  from A304 join konp " +
              "    on A304.knumh = konp.knumh " +
              "   and A304.mandt = konp.mandt " +
              "   and A304.vkorg = '" + salesOrg + "' " +
              "   and A304.vtweg in (" + inDCs + ")" +
              "   and A304.kschl = '" + rrpCondType + "' " +
              "   and A304.mandt = '" + sapClient + "' " +
              "   and konp.kschl = '" + listCondType + "' " +
              "   and char(date, internal) >= chr(A304.datab) " +
              "   and char(date, internal) <= chr(A304.datbi) " +
              "   and A304.kappl = 'V' ";
        jtSingle.execute(sql);
        // Get the changes into a second temp table:
        sql = "create table temp.changedarts as " +
              "select temp.pricechanges.* " +
              "  from temp.pricechanges, zchangedartdc " +
              " where zchangedartdc.matnr = temp.pricechanges.matnr " +
              "   and zchangedartdc.vtweg = temp.pricechanges.vtweg " +
              "   and zchangedartdc.price != temp.pricechanges.price ";
        jtSingle.execute(sql);
        // save the changes, and flag them:
        sql = "update zchangedartdc " +
              "   set (price, changed) = (select price, 'X'  " +
              "                             from temp.changedarts " +
              "                            where zchangedartdc.matnr = temp.changedarts.matnr " +
              "                              and zchangedartdc.vtweg = temp.changedarts.vtweg) " +
              " where matnr||vtweg in (select matnr||vtweg from temp.changedarts) ";
        updates = jtSingle.update(sql);
        // add the new items that weren't there last time, and flag them:
        sql = "insert into zchangedartdc " +
              "select '" + sapClient + "', matnr, vtweg, 'X', price " +
              "  from temp.pricechanges " +
              " where matnr||vtweg not in (select matnr||vtweg from zchangedartdc) ";
        updates = jtSingle.update(sql);
        // now we've got all the changes flagged, we can get the list of changed products:
        jtSingle.query("select distinct matnr from zchangedartdc " +
                       " where changed = 'X' ",
                       new RowCallbackHandler() {
                           public void processRow(ResultSet rs) throws SQLException {
                               prods.add(rs.getString("matnr"));
        // release the connection:
        destroySingleConnection(jtSingle);
        return prods;
     * Return a JdbcTemplate which will always use the same connection. Parameter jt is just
     * a convenient way to get a DataSource from which to get a Connection.
     * When the calling prodedure has finished, it MUST call
     * destroySingleConnection(jt)
     * @param jt
     * @return
    private JdbcTemplate getSingleConTemplate(JdbcTemplate jt) {
        Connection con;
        try {
            con = jt.getDataSource().getConnection();
            con.setAutoCommit(true);
        } catch (SQLException e) {
            throw new DataAccessResourceFailureException("Failed to get Connection for SingleConnectionDataSource", e);
        SingleConnectionDataSource singleDs = new SingleConnectionDataSource(con, true);
        return new JdbcTemplate(singleDs);
    private void destroySingleConnection(JdbcTemplate singleConJt) {
