java.sql.SQLSyntaxErrorException: ORA-00904: " ": invalid identifier错误

原因是sql或hql拼接有问题

错误代码：

 

public GemStorageHistory gemid(String code){
List list=this.daoPersistence.query("from GemStorageHistory gh where gh.gemStorageCode="+code);
return list.size()>0?list.get(0):null;
}

错误原因：拼接字符串有误：gh.gemStorageCode="+code

正确方法：

public GemStorageHistory gemid(String code){
List list=this.daoPersistence.query("from GemStorageHistory gh where gh.gemStorageCode='"+code+"'");
return list.size()>0?list.get(0):null;
}

正确拼接：应给字符串在加个单引号 。如： gh.gemStorageCode=' "+code+" '
