我正在R ipython笔记本(相对R新手)中工作,并试图使用'bigrquery'从Google Big Query中提取数据。我被告知这应该很简单,但使用标准的SQL解压缩不起作用。无法使用bigrquery与标准sql
这里是我的代码:
require("bigrquery")
# Use your project ID here
project <- "project-id" # put your project ID here
standard_sql <- "SELECT year, month, day, weight_pounds FROM `publicdata.samples.natality` LIMIT 5"
legacy_sql <- "SELECT year, month, day, weight_pounds FROM [publicdata:samples.natality] LIMIT 5"
# doesn't work
standard_data <- query_exec(standard_sql, project = project, useLegacySql = FALSE)
# works
legacy_data <- query_exec(legacy_sql, project = project, useLegacySql = TRUE)
有关标准SQL上述返回以下错误:
Error: Invalid table name: `publicdata:samples.natality`
Traceback:
1. query_exec(standard_sql, project = project, useLegacySql = FALSE)
2. run_query_job(query = query, project = project, destination_table = destination_table,
. default_dataset = default_dataset, create_disposition = create_disposition,
. write_disposition = write_disposition, use_legacy_sql = use_legacy_sql,
. quiet = quiet, ...)
3. wait_for(job, quiet = quiet)
4. stop(err$message, call. = FALSE)
它表明我不是标准的SQL正确输入表的名称,但我似乎有,并从GBQ控制台查询运行良好。
怎么回事?
以防万一 - 在所有小字符中尝试使用false –
为您安装了哪种版本的bigrquery?你能为我们打印packageVersion(“bigrquery”)的结果吗? –
小字错误没有工作 - 版本是'0.4.1' - 是旧的一个有什么机会? – goose
