org.hibernate.hql.internal.ast.QuerySyntaxException：意外的標記：左第1行第24列

Question

我試圖從數據庫中查詢數據，但我想刪除特定列的最後三個字符。該SQL是有效的SQL SERVER，但是當我把它進入休眠的語法，日食顯示爲標題，SQL上下文如下：

String sql = "select distinct d.code,LEFT(d.VILLAGE, (LEN(d.VILLAGE)-3)) as village_name from DistrictInfo d where d.county=:region and d.town=:town and LEN(d.VILLAGE) !=0"; 
Query q = session.createQuery(sql); 
q.setString("region", region); 
q.setString("town", town) 

的特例如下：

org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected token: LEFT near line 1, column 24 [select distinct d.code,LEFT(d.VILLAGE, (LEN(d.VILLAGE)-3)) as village_name from org.nergis.orm.model.DistrictInfo d where d.county=:region and d.town=:town and LEN(d.VILLAGE) !=0] 

請問LEFT()導致異常？我怎樣才能做到這一點？

Answer 1

你可以使用Hibernate的createSQLQuery來做到這一點。
