[英]How to query based on condition in dynamo db table?
I have Table with following items where p_id is Primary partition key and p_type (String) is a Primary sort key. 我有带有以下项目的表,其中p_id是主分区键,而p_type(String)是主排序键。
p_id p_type address name phone
1221 Men
I want to write query in node js function with this condition: "select all where p_type ="men" and address.area="abc". 我想在这种情况下在节点js函数中编写查询:“全选p_type =“ men”和address.area =“ abc”。
my address item is a map and it looks like this: 我的地址项目是一张地图,看起来像这样:
"address": {
"M": {
"area": {
"S": "abc"
},
"city": {
"S": "Bengaluru"
},
}
How to achieve this. 如何实现这一目标。 do i have to create global secondary index?if yes how to create it.
