如何在Hibernate查询语言（HQL）中执行左联接

Question

需要从两个表中检索记录

表1： KFT_M_CUSTOMER_CART_LIST

表2： KFT_STATIC_DETAILS

我尝试了这个 SQL 查询，该查询在SQLserver中正常工作

但此查询在 HQL

中不起作用

如何在HQL查询中编写

        preferences = new MyPreferences(context);
        this.imageLoader = ImageLoader.getInstance();

                .discCacheExtraOptions(1000, 1000, Bitmap.CompressFormat.JPEG, 100, null).discCache(new UnlimitedDiscCache(cacheDir)).build();
