Boto3 DynamoDB 查询条件不起作用（eq 除外）

Question

I am using boto3 to create a simple DynamoDB query as follows:

response = table.query(
    KeyConditionExpression=Key('course-lesson-id-part').eq(1)
)

This query works and return the single item just like it should.

course-lesson-id-part is my primary partition key and is numeric; I have two items in my table:

course-lesson-id-part: 1
course-lesson-id-part: 2

Ideally, and according to this reference , I should be able to use the following to query all items with course-lesson-id-part > 0:

response = table.query(
    KeyConditionExpression=Key('course-lesson-id-part').gt(0)
)

None of the other DB Query conditions seem to be working other than.eq, which does me no good here.

Anyone have any ideas?

Answer 1

Only eq is supported for partition keys.

You must specify the partition key name and value as an equality condition.
