Write the Data Frames in an Environment to a SQLite Database

Usage

# S3 method for class 'environment'
rws_write(
  x,
  exists = TRUE,
  delete = FALSE,
  replace = FALSE,
  meta = TRUE,
  log = TRUE,
  commit = TRUE,
  strict = TRUE,
  x_name = substitute(x),
  silent = getOption("rws.silent", FALSE),
  conn,
  all = TRUE,
  unique = TRUE,
  ...
)

Arguments

x: An environment.
exists: A flag specifying whether the table(s) must already exist.
delete: A flag specifying whether to delete existing rows before inserting data. If meta = TRUE the meta data is deleted.
replace: A flag specifying whether to replace any existing rows whose inclusion would violate unique or primary key constraints.
meta: A flag specifying whether to preserve meta data.
log: A flag specifying whether to log the table operations.
commit: A flag specifying whether to commit the operations (calling with commit = FALSE can be useful for checking data).
strict: A flag specifying whether to error if x has extraneous columns or if exists = TRUE extraneous data frames.
x_name: A string of the name of the object.
silent: A flag specifying whether to suppress messages and warnings.
conn: A RSQLite::SQLiteConnection to a database.
all: A flag specifying whether all the existing tables in the data base must be represented.
unique: A flag specifying whether each table must represented by no more than one data frame.
...: Not used.

Examples

conn <- rws_connect()
rws_list_tables(conn)
#> character(0)
atable <- readwritesqlite::rws_data
another_table <- readwritesqlite::rws_data
not_atable <- 1L
rws_write(environment(), exists = FALSE, conn = conn)
rws_list_tables(conn)
#> [1] "another_table" "atable"       
rws_disconnect(conn)
