R Documentation

Upload to a SQL Server database using odbc

Description

The function performs some extra configuration to improve robustness.

Usage

upload_sqls_odbc(
  d,
  schema_name,
  table_name,
  dsn_name,
  clear_table = FALSE,
  create_table = FALSE,
  convert_logical_to_integer = FALSE,
  timezone = "UTC",
  timezone_out = "UTC",
  transaction = FALSE,
  verbose = TRUE,
  verbose_detail = FALSE
)

Arguments

`d`	Dataset to be uploaded to the dataset. The object must inherit from `data.frame`.
`schema_name`	Name of the database destination table.
`table_name`	Name of the database destination table.
`dsn_name`	Name of the locally-defined DSN passed to `DBI::dbConnect()`.
`clear_table`	If `TRUE`, calls deletes or truncates all records before writing to the table.
`create_table`	If the table structure has not yet been defined in the database, it will be created if `create_table` is `TRUE`.
`convert_logical_to_integer`	Convert all `logical` columns to `integer`. This helps the database store the values as bits.
`timezone`	The server time zone. Passed to `DBI::dbConnect()`.
`timezone_out`	The time zone returned to R. Passed to `DBI::dbConnect()`. See https://www.tidyverse.org/blog/2019/12/odbc-1-2-0/.
`transaction`	Should the clear and upload steps be wrapped in a rollback transaction?
`verbose`	Display messages about the status of an upload.
`verbose_detail`	Display a message about the connection's low-level details.

Details

If transaction is TRUE and the upload fails, the table is rolled back to the state before function was called. This includes rolling back the (optional) clearing of records, and uploading the new records. Decide if it's more robust to rollback to the previous state, or if it's better to leave the table in the incomplete state. The latter is helpful diagnosing which record caused the write to fail; look at the last successful record contained in the database

Value

A boolean value that was returned by DBI::dbWriteTable().
