Reads the file specified by path as a shapefile and copies its
contents into a new table tableName in the database.
Define fileEncoding to force encoding (useful when the header is
missing encoding information).
If the tablename parameter is not specified, then the resulting table has the same name as the shapefile.
Warning on the input file name
When a tablename is not specified, special caracters in the input file name are not allowed. The possible caracters are as follow: A to Z, _ and 0 to 9.
