Description

Retrieve the number of columns of a table in a database (referenced by

'edb'). Notice that the methods do NOT retrieve the full table to

get its column names (so it should work even if the table is big).

Arguments

edb

tableName

Single character string. Name of the table to read in 'edb'.

...

Additional parameters to be passed to class-specific method. See

methods("edbColnames").
