Question

我正在将日期传递到SQL查询中（这在我拥有的其他代码中有效），但由于某种原因，此处的表现不佳。我将在下面发布代码。

 Calendar limitDate = Calendar.getInstance();
        limitDate.set(Calendar.HOUR_OF_DAY, 0);
        limitDate.set(Calendar.MINUTE, 0);
        limitDate.set(Calendar.SECOND, 0);
        limitDate.set(Calendar.MILLISECOND, 0);
        //remove records 221 days old or older
        limitDate.add(Calendar.DAY_OF_YEAR, -221);
        java.sql.Date sqlDate = new java.sql.Date(limitDate.getTimeInMillis());
        int deleteCnt = 0;
        SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
        Date date = new Date();

        StringBuilder wgpSql = new StringBuilder("select wgpapt.* ");
        wgpSql.append("from THB_View.WGPAPT wgpapt ");
        wgpSql.append("left outer join THB_View.WGP wgp on wgpapt.WGP_TAG = wgp.WGP_TAG ");
        wgpSql.append("where wgpapt.CREATE_DATE <= '" + sqlDate + "' ");
        wgpSql.append("and wgp.RECORD_KEY is null");
        List<Object[]> sqlResultSet = ExecuteSql.executeNativeSqlString(wgpSql.toString(), null);

我在控制台中遇到的错误是：以'Ljava.lang.Object; @ 4906038d，[Ljava.lang.Object; @ 366cabed，[Ljava.lang.Object; @ 651d74a9，[Ljava。 lang.Object; @ 354aea35，[Ljava.lang.O'过长。最大长度为128。

Answer 1

我解决了自己的问题。我的SQL语句说("select wgpapt.* ");，它获取整个结果而不是我尝试获取的记录键序列。这太长了，导致我的代码出错。

解决方案是将我的select语句更改为

("select wgpapt.RECORD_KEY ");

以'x'开头的标识符太长（SQL）
