Metadata about a remote table
remote_name() gives the name remote table, or NULL if it's a query.
remote_query() gives the text of the query, and remote_query_plan()
the query plan (as computed by the remote database). remote_src() and
remote_con() give the dplyr source and DBI connection respectively.
remote_name(x) remote_src(x) remote_con(x) remote_query(x) remote_query_plan(x)
x |
Remote table, currently must be a tbl_sql. |
The value, or NULL if not remote table, or not applicable.
For example, computed queries do not have a "name"
mf <- memdb_frame(x = 1:5, y = 5:1, .name = "blorp") remote_name(mf) remote_src(mf) remote_con(mf) remote_query(mf) mf2 <- dplyr::filter(mf, x > 3) remote_name(mf2) remote_src(mf2) remote_con(mf2) remote_query(mf2)
