tabul data transfer --help

Tabul data transfer
===================

Transfer one or more data resources.



Examples
--------

 1 - To download the table `time` from the data store `sqlite` into the file `time.csv`, you would execute


        tabul data transfer time@sqlite time.csv


 2 - To download all the table that starts with `dim` from the data store `oracle` into the directory `dim`, you would execute


        tabul data transfer dim*@oracle dim


 3 - To download the data of the query defined in the file `QueryToDownload.sql` and executed against the data store `sqlite` into the file `QueryData.csv`, you would execute the following command:


        tabul data transfer (QueryToDownload.sql)@sqlite QueryData.csv


 4 - To download the data of all query defined in all `sql` files of the current directory, execute them against the data store `sqlite` and save the results into the directory `result`, you would execute the following command:


        tabul data transfer (*.sql)@sqlite result


 5 - Transfer the result of the query `top10product` from sqlite to the table `top10product` of sql server


        tabul data transfer (top10product.sql)@sqlite @sqlserver
