使用 dbplyr 创建 SQL 查询时出现问题

Problem using dbplyr to create a SQL query

我正在尝试创建一个查询来清理 SQL 中的数据,但我不知道 SQL。为此,我创建了一个数据集样本并使用 dplyr 来清理和创建我想要的最终数据,然后我想使用 dbplyr 来创建查询。但是我在创建查询时遇到了问题

data <- read_csv("DataBase/raw/bquxjob_1016f9df_180d80c269e.csv")

#Creating query I will run in SQL
data %>% 
  filter(codigo_natureza_juridica == 2046 
         | codigo_natureza_juridica  ==  2054 
         | codigo_natureza_juridica == 2062
         | codigo_natureza_juridica == 2070
         | codigo_natureza_juridica == 2089
         | codigo_natureza_juridica == 2097 
         | codigo_natureza_juridica == 2135
         | codigo_natureza_juridica == 2232
         | codigo_natureza_juridica == 2240
         | codigo_natureza_juridica == 2259
         | codigo_natureza_juridica == 2267 &
           data_inicio_atividade <= '2011-12-31') %>%
  mutate(year_open             = format(data_inicio_atividade, format ="%Y"),
         month_open            = format(data_inicio_atividade, format ="%m"),
         date_open             = format(data_inicio_atividade, format ="%Y%m"),
         year_close            = ifelse(situacao_cadastral != 2, 
                                        format(data_situacao_cadastral, format ="%Y"),
                                        NA),
         month_close           = ifelse(situacao_cadastral != 2, 
                                        format(data_situacao_cadastral, format ="%m"),
                                        NA),
         date_close           = ifelse(situacao_cadastral != 2, 
                                        format(data_situacao_cadastral, format ="%Y%m"),
                                        NA),
         open_2007              = ifelse(year_open <= 2007, 1,0)) %>%
  show_query()


此代码出现以下错误:

Error in UseMethod("show_query") : 
  no applicable method for 'show_query' applied to an object of class "c('tbl_df', 'tbl', 'data.frame')"

show_query() 仅适用于数据库,而您正试图在数据帧上使用它。要将数据从 csv 发送到临时数据库对象以创建查询,您可以使用 tbl_memdb() 而不是:

data %>% 
  tbl_memdb() %>%
  filter(...) %>%
  mutate(...) %>%
  show_query()
