Arguments

`...`	Other arguments to methods.
`object`	Any R object
`dbObj`	An object inheriting from DBIObject, i.e. DBIDriver, DBIConnection, or a DBIResult
`obj`	An R object whose SQL type we want to determine.
`conn`	A DBIConnection object, as returned by `dbConnect()`.
`statement`	a character string containing SQL.
`params`	For `dbBind()`, a list of values, named or unnamed, or a data frame, with one element/column per query parameter. For `dbBindArrow()`, values as a nanoarrow stream, with one column per query parameter.
`x`	A character vector to quote as string.
`name`	The table name, passed on to `dbQuoteIdentifier()`. Options are: a character string with the unquoted DBMS table name, e.g. `"table_name"`, a call to `Id()` with components to the fully qualified table name, e.g. `Id(schema = "my_schema", table = "table_name")` a call to `SQL()` with the quoted and fully qualified table name given verbatim, e.g. `SQL('"my_schema"."table_name"')`
`value`	A data.frame (or coercible to data.frame).
`overwrite`	a logical specifying whether to overwrite an existing table or not. Its default is `FALSE`.
`append`	a logical specifying whether to append to an existing table in the DBMS. Its default is `FALSE`.
`field.types`, `temporary`	Ignored. Included for compatibility with generic.
`row.names`	A logical specifying whether the `row.names` should be output to the output DBMS table; if `TRUE`, an extra field whose name will be whatever the R identifier `"row.names"` maps to the DBMS (see `DBI::make.db.names()`). If `NA` will add rows names if they are characters, otherwise will ignore.
`fields`	Either a character vector or a data frame. A named character vector: Names are column names, values are types. Names are escaped with `dbQuoteIdentifier()`. Field types are unescaped. A data frame: field types are generated using `dbDataType()`.
`res`	An object inheriting from DBIResult.
`n`	maximum number of records to retrieve per fetch. Use `n = -1` or `n = Inf` to retrieve all pending records. Some implementations may recognize other special values.
