Question

您好，我正在使用JDBC查询，但出现此错误，但是我不明白为什么，或者该错误的确切含义以及查询的错误所在。查询如下

private List<StatisticsLog>  runStatistics(Integer partnerId, LocalDate ldStart, LocalDateTime ldtEnd, String statType)
    {
        return jdbcTemplate.query("SELECT S.APP_ID, S.LOG_TYPE, ACC.CONTACT_PERSON_FIRST_NAME, ACC.CONTACT_PERSON_LAST_NAME, ACV.VERSION_APP_NAME, "
                + "'" + statType.trim() + "' STATTYPE, "
                + "ACV.APP_CATALOG_ID, ACV.APP_CATALOG_VERSION_ID, ACV.VERSION, ACV.UPDATED_AT, ACV.VERSION_LOGO_EXT, ACV.HAS_LOGO, "
                + "LANG.LANGUAGE_NAME_SHORT, LANG.LANGUAGE_ID , S.count, S.PARTNER_ID, APP.CREATED_AT "
                + "FROM (SELECT partner_id, log_type, app_id, language_id, count(*) as count FROM public.statistics_log "
                + " WHERE partner_id = ? "
                + " and logged_at between ? and ? "
                + "group by 1, log_type, app_id, language_id) as S "
                + "INNER JOIN APP_CATALOG_ACCOUNT ACP ON ACP.APP_CATALOG_SERIAL_ID = S.APP_ID "
                + "INNER JOIN APP_CATALOG APP ON APP.APP_CATALOG_SERIAL_ID = S.APP_ID "
                + "INNER JOIN ACCOUNT ACC ON ACC.ACCOUNT_ID = S.PARTNER_ID "
                + "INNER JOIN APP_CATALOG_VERSION ACV on ACV.APP_CATALOG_SERIAL_ID = APP.APP_CATALOG_SERIAL_ID AND ACV.STATUS = 3 "
                + "INNER JOIN LANGUAGE LANG ON LANG.LANGUAGE_ID = ACV.LANGUAGE_ID "
                + "ORDER BY S.count desc ",
                new Object[] { partnerId, ldStart, ldtEnd }, new StatisticsLogRowMapper());
    }

我从属于应用程序目录的CREATED_AT列中得到了错误，我认为应该在该列中，此外，为了更加详细，我还将附加StatisticsLogRowMapper

public class StatisticsLogRowMapper implements RowMapper<StatisticsLog>
{
    @Override
    public StatisticsLog mapRow(ResultSet rs, int rowNum) throws SQLException
    {
        StatisticsLog stat = new StatisticsLog();

        stat.setAppId(rs.getInt("APP_ID"));
        stat.setPartnerId(rs.getInt("PARTNER_ID"));
        stat.setCount(rs.getLong("COUNT"));
        stat.setCreatedAt(rs.getTimestamp("CREATED_AT").toLocalDateTime());
        stat.setPartnerFirstName(rs.getString("CONTACT_PERSON_FIRST_NAME"));
        stat.setPartnerLastName(rs.getString("CONTACT_PERSON_LAST_NAME"));
        stat.setAppNameDefault(rs.getString("VERSION_APP_NAME"));
        stat.setAppCatalogId(rs.getInt("APP_CATALOG_ID"));
        stat.setStatType(rs.getString("STATTYPE"));
        stat.setLogType(LogTypeEnum.valueOf(rs.getString("LOG_TYPE").trim()));
        stat.setAppCatalogVersionId(rs.getInt("APP_CATALOG_VERSION_ID"));
        stat.setVersion(rs.getInt("VERSION"));
        stat.setUpdatedAt(rs.getDate("UPDATED_AT"));
        stat.setVersionLogoExt(rs.getString("VERSION_LOGO_EXT"));
        stat.setHasLogo(rs.getBoolean("HAS_LOGO"));
        stat.setLanguageNameShort(rs.getString("LANGUAGE_NAME_SHORT"));
        stat.setLanguageId(rs.getInt("LANGUAGE_ID"));

        return stat;
    }
}

错误是：“ PreparedStatementCallback；错误的SQL语法[SELECT S.APP_ID，S.LOG_TYPE，ACC.CONTACT_PERSON_FIRST_NAME，ACC.CONTACT_PERSON_LAST_NAME，ACV.VERSION_APP_NAME，“ days30” STATTYPE，ACV.APP_CATALOG_ID，ACV.APP_CATALOG_ID， VERSION，ACV.UPDATED_AT，ACV.VERSION_LOGO_EXT，ACV.HAS_LOGO，LANG.LANGUAGE_NAME_SHORT，S.count，S.PARTNER_ID FROM（选择partner_id，log_type，app_id，language_id，count（*）作为来自public.statistics_log的计数，在？和？按1，log_type，app_id，language_id，partner_id分组），如S INNER JOIN APP_CATALOG_ACCOUNT ACP在ACP.APP_CATALOG_SERIAL_ID = S.APP_ID INNER JOIN APP_CATALOG APP在APP.APP_CATALOG_SERIAL_ID = S.APP_ID INNER JOIN帐户ACC上.PARTNER_ID内联接AC_上的APP_CATALOG_VERSION ACV.APP_CATALOG_SERIAL_ID = APP.APP_CATALOG_SERIAL_ID和ACV.STATUS = 3内联接语言LANG.LANGUAGE_ID = ACV.LANGUAGE_ID ORDER BY S.count descorg]；嵌套异常是SQL。：在此ResultSet中找不到列名CREATED_AT。”

在错误字段中没有该字段

如果您有任何疑问或可能尝试解决的问题，请不要犹豫，我将不胜感激，即使是最小的帮助也要感谢您。

Answer 1

我看到查询的第二行有一个错误-+“'” + statType.trim（）+“'STATTYPE，”，在引号之后。 STATTYPE没有表引用，并附加有字符串。那可能是另一个问题。我没有足够的声誉，所以无法对这个问题发表评论。

错误的SQL语法-在此ResultSet中找不到列名吗？
