copy_inline uses UNION ALL

Code
  copy_inline(con, y %>% slice(0)) %>% remote_query()
Output
  <SQL> SELECT CAST(NULL AS INTEGER) AS `id`, CAST(NULL AS TEXT) AS `arr`
  WHERE (0 = 1)
Code
  copy_inline(con, y) %>% remote_query()
Output
  <SQL> SELECT CAST(`id` AS INTEGER) AS `id`, CAST(`arr` AS TEXT) AS `arr`
  FROM (
    SELECT NULL AS `id`, NULL AS `arr`
    WHERE (0 = 1)

    UNION ALL

    SELECT 1, '{1,2,3}'
  ) AS `values_table`
Code
  copy_inline(con, y %>% slice(0), types = types) %>% remote_query()
Output
  <SQL> SELECT CAST(NULL AS bigint) AS `id`, CAST(NULL AS integer[]) AS `arr`
  WHERE (0 = 1)
Code
  copy_inline(con, y, types = types) %>% remote_query()
Output
  <SQL> SELECT CAST(`id` AS bigint) AS `id`, CAST(`arr` AS integer[]) AS `arr`
  FROM (
    SELECT NULL AS `id`, NULL AS `arr`
    WHERE (0 = 1)

    UNION ALL

    SELECT 1, '{1,2,3}'
  ) AS `values_table`

custom clock functions translated correctly

Code
  test_translate_sql(date_count_between(date_column_1, date_column_2, "year"))
Condition
  Error in `date_count_between()`:
  ! `precision = "year"` isn't supported on database backends.
  i It must be "day" instead.

Code
  test_translate_sql(date_count_between(date_column_1, date_column_2, "day", n = 5))
Condition
  Error in `date_count_between()`:
  ! `n = 5` isn't supported on database backends.
  i It must be 1 instead.

difftime is translated correctly

Code
  test_translate_sql(difftime(start_date, end_date, units = "auto"))
Condition
  Error in `difftime()`:
  ! `units = "auto"` isn't supported on database backends.
  i It must be "days" instead.

Code
  test_translate_sql(difftime(start_date, end_date, tz = "UTC", units = "days"))
Condition
  Error in `difftime()`:
  ! Argument `tz` isn't supported on database backends.
