Description

Create a flight query object for use in run function

Usage

flt_query(conn, ems_name, data_file)

Arguments

conn	A connection object generated by connect
ems_name	A string, indicating the name of the EMS server. Will return an informative error if you use the wrong name.

Details

This function uses a connection object to create a flight query object. These can be manipulated using the filter, select and other functions before passing to run to execute and return a dataframe. This object won't work by itself - you will need to set a database, select elements etc for it to work.

A FltQuery object to be manipulated and then run.

conn <- connect("joe.bloggs", "mypassword")
qry <- flt_query(conn, "my-ems", data_file = "metadata.db")
