以下是我的产品实体表

我想从table中获取数据，其中user_id不应该等于12,36,43

如何为其编写选择查询

当前的SQL查询 -

从catalog_product_entity中选择*，其中entity_id = 12345;

我想要没有user_id 12,36,43的结果

desc catalog_product_entity;

尝试此查询：

id:= "ket"
c.EnsureIndexKey("hobby")
err = c.Find(bson.M{"$hobby": bson.M{"$search": id,},}).All(&result)

使用WHERE ... NOT IN：

SELECT * FROM catalog_product_entity
