Description

Send query, retrieve results and then clear result set

Usage

## S4 method for signature 'AthenaConnection,character'
dbGetQuery(conn, statement, statistics = FALSE, unload = athena_unload(), ...)

Arguments

conn	A DBIConnection object, as returned by dbConnect().
statement	a character string containing SQL.
statistics	If set to TRUE will print out AWS Athena statistics of query.
unload	boolean input to modify 'statement' to align with AWS Athena UNLOAD, default is set to FALSE.

Note

If the user does not have permission to remove AWS S3 resource from AWS Athena output location, then an AWS warning will be returned. For example AccessDenied (HTTP 403). Access Denied.
