xqj でクエリを実行しようとすると、このエラーが発生します。

Exception in thread "main" javax.xml.xquery.XQException:
  XQJQS001 - Invalid XQuery syntax, syntax does not pass static validation.
  Root Cause:
  XQueryParseException: Encountered "$" at line 1, column 36.

public static void Consultar(XQConnection connexio) throws XQException { Scanner sc = new Scanner(System.in);

    System.out.println(">>>>Please select a mminim stock :)");

    int selec = sc.nextInt();

    String squery = "for $prod  in /productos/produc"
            + "for $zone in $prod/cod_zona"
            + "let $stock :=$prod/stock_minimo"

    XQPreparedExpression consulta = connexio.prepareExpression(squery);

    XQResultSequence resultat = consulta.executeQuery();

    while (resultat.next()) {
        System.out.println(resultat.getItemAsString(null));
        System.out
                .println("...................................................................");
    }

    connexio.close();

}

文字列連結式

  "for $prod  in /productos/produc"
+ "for $zone in $prod/cod_zona"

文字列を生成します

for $prod  in /productos/producfor $zone in $prod/cod_zona

producとの間にある種の空白を追加する必要がありforます+。

String squery = "for $prod  in /productos/produc "
            + "for $zone in $prod/cod_zona "
            + "let $stock :=$prod/stock_minimo "
            + "let $deno :=$prod/denominacion "
            // etc etc.
