hql里面不能用*，你把count(*)改成count(1)就可以了
还是不行啊 错误信息如下 1. unexpected token: 1 near line 1, column 14 [select count(1) from cn.com.su.domain.Material m inner join fetch m.material_supplier s where 1=1] 2. unexpected token: 1 near line 1, column 14 [select count(1) from cn.com.su.domain.Material m inner join fetch m.material_supplier s where 1=1]; nested exception is org.hibernate.hql.ast.QuerySyntaxException: unexpected token: 1 near line 1, column 14 [select count(1) from cn.com.su.domain.Material m inner join fetch m.material_supplier s where 1=1]
换成count(1)还是不行啊，错误信息如上
Material m inner join fetch m.material_supplier 1、hql不需要join Class中的属性就可以where 1-1 and m.material_supplier .id=xxx

有material_supplier这个属性的
下面是Material类的配置文件
<hibernate-mapping>
<class name="cn.com.su.domain.Material">
<id name="material_id" type="java.lang.String" length="32">
<generator class="uuid"></generator>
</id>
<property name="material_name" type="java.lang.String" length="20"></property>
<property name="material_num" type="java.lang.String" length="20"></property>
<property name="material_brand" type="java.lang.String" length="20"></property>
<property name="material_standard" type="java.lang.String" length="20"></property>
<property name="material_price" type="java.lang.Long" length="8"></property>
<property name="material_desc" type="java.lang.String" length="500"></property>
<property name="material_unit" type="java.lang.String" length="10"></property>
<many-to-one name="material_type" class="cn.com.su.domain.Type" cascade="all">

</class>

问题其实是我有个查询条件是Supplier类的，我想按条件查询Material的总数
try {
String countHql = "select count(*) " + hql;
int count = ((Long) getHibernateTemplate().find(countHql).get(0))
.intValue();
return count;
} catch (RuntimeException ex) {
log.error("find by getCountByHql", ex);
throw ex;
}
}
我是这样查询的
