Run AWS Athena’s queries with Lambda function

问题

I created a table on AWS Athena on which I can run any query without any error:

select * from mytestdb.test

The table has three columns, customer_Id, product_Id, price.

I tried to create a lambda function that run the same query for me using boto3:

import time
import boto3

DATABASE = 'mytestdb'
TABLE = 'test'

output='s3://mybucketons3/'

COLUMN = 'Customer_Id'

def lambda_handler(event, context):

    keyword = 'xyz12345'

    query = "SELECT * FROM %s.%s where %s = '%s';" % (DATABASE, TABLE, COLUMN, keyword)

    client = boto3.client('athena')

    # Execution
    response = client.start_query_execution(
        QueryString=query,
        QueryExecutionContext={
            'Database': DATABASE
        },
        ResultConfiguration={
            'OutputLocation': output,
        }
    )


    return

However I got the following error:

Response:
{
  "errorMessage": "An error occurred (AccessDeniedException) when calling the StartQueryExecution operation: User: arn:aws:sts::076088932150:assumed-role/Test/QueryTest is not authorized to perform: athena:StartQueryExecution on resource: arn:aws:athena:us-west-2:076088932150:workgroup/primary",
  "errorType": "ClientError",

It seems sort of access issue however I am not sure why because I have both lambda and athena db with the same account.

As I've mentioned in the comment, your Lambda role should contain Allow policy to interact with Athena service. I've also added full permissions for your S3 bucket. Example:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "Stmt1547414166585",
      "Action": [
        "athena:StartQueryExecution"
      ],
      "Effect": "Allow",
      "Resource": "*"
    },
    {
      "Sid": "Stmt1547414166586",
      "Action": [
        "s3:*"
      ],
      "Effect": "Allow",
      "Resource": "arn:aws:s3:::your-bucket-name/*"
    } 
  ]
}
