basically this is the start of my query/code:
dbGetQuery(con,'SELECT user_id, unique_id
where order_date > parse_datetime('2021-11-01')')
(took out a load because this gets the point across).
The query is quite long and uses the date from above a good few times. So I was wondering if I can create a variable and replace the date.
Something in the format:
date_variable <- 2021-11-01
dbGetQuery(con,'SELECT user_id, unique_id
where order_date > parse_datetime('date_variable')')
I am very new to R and don't really know what I'm doing so any help would be appreciated!
Thanks!
Yes, you can. I prefer to use glue
package for this:
library(glue)
library(DBI)
date_variable <- as.Date("2021-11-01")
query <- glue_sql("SELECT user_id, unique_id where order_date > parse_datetime({date_variable})",
date_variable = date_variable,
.con = con)
dbGetQuery(con, query)
