如何在 AWS 和 boto3 中將 f-Literal 與 PartiQL 一起使用以及排序鍵的條件

Question

這是我目前的代碼

table_name = 'TableName'
pk = "CID-73665"
Condition = "begins_with(sk,'CUS#')"

# get item 
stmt = f"SELECT * FROM {table_name} WHERE pk=? and {Condition}"
pmt =[{
    "S": pk
    },
    {
     "S": sk   
    }]

resp = dynamodb_client.execute_statement(
    Statement=stmt , Parameters= pmt
 )

pp.pprint(resp['Items'])

但我收到此錯誤消息：

NameError: name 'sk' is not defined

任何人都知道什么可能是錯的？

Answer 1

嗯，'sk' 沒有定義。 你這樣試試

table_name = "TableName"
pk = "CID-73665"
sk = "CUS#"

# get item
stmt = f"SELECT * FROM {table_name} WHERE pk=? and begins_with('sk', ?)"
pmt = [{"S": pk}, {"S": sk}]

resp = dynamodb_client.execute_statement(Statement=stmt, Parameters=pmt)

pp.pprint(resp["Items"])
