Usage
## S3 method for class 'MySQLConnection,character,data.frame':
dbWriteTable(conn, name, value,
field.types = NULL, row.names = TRUE, overwrite = FALSE,
append = FALSE, ..., allow.keywords = FALSE)## S3 method for class 'MySQLConnection,character,character':

quote = "\\"", ...)
Arguments
conn
a MySQLConnection object, produced by
dbConnect name
a character string specifying a table name.
value
a data.frame (or coercible to data.frame) object or a
file name (character). In the first case, the data.frame is
written to a temporary file and then imported to SQLite; when value
is a character, it is interpreted as a file name and its co
field.types
character vector of named SQL field types where
the names are the names of new table's columns. If missing, types inferred
with dbDataType). 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
overwrite
a logical specifying whether to overwrite an existing table
or not. Its default is FALSE. (See the BUGS section below)
append
a logical specifying whether to append to an existing table
in the DBMS. Its default is FALSE.
...
Unused, needs for compatibility with generic.
allow.keywords
logical indicating whether column names that happen to
be MySQL keywords be used as column names in the resulting relation (table)
being written. Defaults to FALSE, forcing mysqlWriteTable to modify column
names to make them legal MySQL identifiers.
header
logical, does the input file have a header line? Default is the
same heuristic used by read.table, i.e., TRUE if the first
line has one fewer column that the second line.
nrows
number of lines to rows to import using read.table from
the input file to create the proper table definition. Default is 50.
sep
field separator character
skip
number of lines to skip before reading data in the input file.
quote
the quote character used in the input file (defaults to
".)
