These functions are deprecated in favor of better alternatives. Most functions with the cdm_ prefix have an identical alternative with a dm_ prefix.

sql_schema_*() functions have been replaced with the corresponding db_schema_*() functions.

dm_join_to_tbl() is deprecated in favor of dm_flatten_to_tbl().

dm_is_referenced() is soft-deprecated, use the information returned from dm_get_all_fks() instead.

dm_get_referencing_tables() is soft-deprecated, use the information returned from dm_get_all_fks() instead.

validate_dm() has been replaced by dm_validate() for consistency.

dm_add_tbl is deprecated as of dm 1.0.0, because the same functionality is offered by dm() with .name_repair = "unique".

dm_bind() is deprecated as of dm 1.0.0, because the same functionality is offered by dm().

dm_squash_to_tbl() is deprecated as of dm 1.0.0, because the same functionality is offered by dm_flatten_to_tbl() with recursive = TRUE.

rows_truncate() is deprecated as of dm 1.0.0, because it's a DDL operation and requires different permissions than the dplyr::rows_*() functions.

Arguments

...

These dots are for future extensions and must be empty.

force

Boolean, if FALSE (default), an error will be thrown if there is already a primary key set for this table. If TRUE, a potential old pk is deleted before setting a new one.

dm

A dm object.

table

A table in the dm.

table_1

One of the tables involved in the join.

table_2

The second table of the join.

join

The type of join to be performed, see dplyr::join().

x

An object.

check

Boolean, if TRUE, a check is made if the combination of columns is a unique key of the table.

columns

Table columns, unquoted. To define a compound key, use c(col1, col2).
