Breaking down customer transactions in SQL

Given the following table containing customer transaction data:

Table name: orders

	order_id	channel	date	month	revenue
0	1	Online	2018-09-01	09	100
1	2	Online	2018-09-03	09	125
2	3	In_store	2018-10-11	10	200
3	4	In_store	2018-08-21	08	80
4	5	Online	2018-08-13	08	200
5	6	Online	2018-10-29	10	100

Write SQL queries to answer the following:

• Return all rows in the data table with transaction values over $101.
• Return all rows in the data table with transaction values over $101 that were purchased through the Online channel.
• Return all rows in the data table with transaction values that were either over $101 OR were purchased In_store.
• Return the minimum transaction amount for both channels as well as the corresponding order id.
