fix: remove single quotes in SQL statement

[leungi]

Issue

With reference to the code chuck below, the single quotes around table variable generates incorrect SQL syntax for connection of type Microsoft SQL Server.

con <- DBI::dbConnect(
    odbc::odbc(),
    Driver   = my_driver,
    Server   = my_server,
    Database = my_database,
    Port     = my_port,
    Trusted_Connection = "Yes"
  )

class(con)
#> [1] "Microsoft SQL Server"
#> attr(,"package")
#> [1] ".GlobalEnv"

get_partitions(con, "my_table", "my_column")
#> Error: nanodbc/nanodbc.cpp:1617: 42000: [Microsoft][ODBC SQL Server Driver][SQL Server]Incorrect syntax near 'my_table'.  [Microsoft][ODBC SQL Server Driver][SQL Server]Statement(s) could not be prepared. 
<SQL> 'SELECT distinct(my_column) FROM 'my_table''

Reference Code Chunk

parquetize/R/get_partitions.R

Line 32 in 4523002

DBI::dbGetQuery(conn, glue::glue("SELECT distinct({`column`}) FROM '{`table`}'", .con = conn))[,1]
