sqlCreateTable {DBI} | R Documentation |
Exposes interface to simple CREATE TABLE
commands. The default
method is ANSI SQL 99 compliant.
This method is mostly useful for backend implementers.
sqlCreateTable(con, table, fields, row.names = NA, temporary = FALSE, ...)
con |
A database connection. |
table |
Name of the table. Escaped with
|
fields |
Either a character vector or a data frame. A named character vector: Names are column names, values are types.
Names are escaped with A data frame: field types are generated using
|
row.names |
Either If A string is equivalent to For backward compatibility, |
temporary |
If |
... |
Other arguments used by individual methods. |
If you implement one method (i.e. for strings or data frames), you need to implement both, otherwise the S4 dispatch rules will be ambiguous and will generate an error on every call.
