tbl_query() is an experimental variant of dplyr::tbl() +

tbl_function() is an experimental variant of dplyr::tbl() to create a lazy table from a table-generating function, useful for reading nonstandard CSV files or other data sources. It is safer than dplyr::tbl() because there is no risk of misinterpreting the query. -Use dplyr::tbl(src, dplyr::sql("SELECT ... FROM ...")) for custom SQL queries. See https://duckdb.org/docs/data/overview for details on data importing functions.

+

As an alternative, use dplyr::tbl(src, dplyr::sql("SELECT ... FROM ...")) for custom SQL queries.

+

tbl_query() is deprecated in favor of tbl_function().

+

Use simulate_duckdb() with lazy_frame() +to see simulated SQL without opening a DuckDB connection.
