dbAppendTable-DatabaseConnectorConnection-character-data.frame-method: Insert rows into a table

Description Usage Arguments Details See Also

Description

The dbAppendTable() method assumes that the table has been created beforehand, e.g. with dbCreateTable(). The default implementation calls sqlAppendTableTemplate() and then dbExecute() with the param argument. Backends compliant to ANSI SQL 99 which use ? as a placeholder for prepared queries don't need to override it. Backends with a different SQL syntax which use ? as a placeholder for prepared queries can override sqlAppendTable(). Other backends (with different placeholders or with entirely different ways to create tables) need to override the dbAppendTable() method.
