Table paths

+ Source: R/table-name.R +
is_table_path.Rd
+
+ +
+

dbplyr standardises all the ways of referring to a table (i.e. a single +string, a string wrapped in I(), a DBI::Id() and the results of +in_schema() and in_catalog()) into a table "path" of the form +table, schema.table, or catalog.schema.path. A table path is +always suitable for inlining into a query, so user input is quoted unless +it is wrapped in I().

+

This is primarily for internal usage, but you may need to work with it if +you're implementing a backend, and you need to compute with the table path, +not just pass it on unchanged to some other dbplyr function.

  • is_table_path() returns TRUE if the object is a table_path.

    • +

  • as_table_path() coerces known table identifiers to a table_path.

    • +

  • check_table_path() throws an error if the object is not a table_path.

    • +

  • table_path_name() returns the last component of the table path (i.e. +the name of the table).

    • +

  • table_path_components() returns a list containing the components of each +table path.

    • +

A table_path object can technically be a vector of table paths, but +you will never see this in table paths constructed from user inputs.

+
