【问题描述】：
原因：org.hibernate.QueryException：无法解析请求 CAST 的类型：INT [ SELECT SUBSTRING(referenceComptable , 8, 14) AS seqNum, SUBSTRING(referenceComptable, 4,7) AS yearCegid, SUBSTRING(referenceComptable, 1,3) 作为期刊 FROM com.dso.model.comptabilite.cegid.EtapeJudiciaireLnkFactureActesHonoraires WHERE dateCegidGenerated BETWEEN :date AND :dateYearIntervalDate ORDER BY CAST(seqNum AS INT), CAST(yearCegid AS INT), CAST(journal AS INT) 升序 ]
HQL 查询： public ScrollableResults retrieveSequenceNumberForCegidGenerated(){
StringBuilder queryBuilder = new StringBuilder(" SELECT SUBSTRING(referenceComptable , 8, 14) AS seqNum, SUBSTRING(referenceComptable, 4,7) AS yearCegid, SUBSTRING(referenceComptable, 1,3) AS journal")
.append(" FROM EtapeJudiciaireLnkFactureActesHonoraires ")
.append(" WHERE dateCegidGenerated BETWEEN :date AND :dateYearIntervalDate ")
.append(" ORDER BY CAST(seqNum AS INT), CAST(yearCegid AS INT), CAST(journal AS INT) ASC ");
Query query = getFilteredCurrentSession().createQuery(queryBuilder.toString());
//SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
Date date = new Date();
LocalDate yearIntervalDate = LocalDate.now().minusDays(365);
Date dateYearIntervalDate = Date.from(yearIntervalDate.atStartOfDay(ZoneId.systemDefault()).toInstant());
query.setParameter("date", date);
query.setParameter("dateYearIntervalDate", dateYearIntervalDate);
ScrollableResults referenceComptable = query.scroll(ScrollMode.FORWARD_ONLY);
query.setCacheMode(CacheMode.IGNORE)
.setFetchSize(500);
return referenceComptable;
}
当我尝试将其转换为 INT 时，它也不起作用。如何将其从字符串转换为整数？

【问题讨论】：
-
As from hibernate document,"cast(... as ...), 其中第二个参数是 Hibernate 类型的名称，" 尝试使用 'int' 而不是 INT 进行类型匹配
-
... 或
CAST(... AS integer)。请注意，Hibernate 类型区分大小写。
