无法从MonetDB.R指定架构名称

Question

I am trying to connect to a table that is not in the sys schema. The code below works if sys.tablea exists.

conn <- dbConnect(dbDriver("MonetDB"), "monetdb://localhost/demo")
frame <- monet.frame(conn,"tablea")

If I define tablea in a different schema, eg xyz.tablea, then I get the error message

Server says 'SELECT: no such table 'tablea'' [#NA]

The account used to connect has rights to the table.

In a related question, is it possible to use camel-case from MonetDB.R? When I change the table name to TableA, the server again responds with

Server says 'SELECT: no such table 'tablea'' [#NA]

where the table name is all lower-case.

Answer 1

Using tables in other schemata is not possible with the current constructor of monet.frame. However, you can work around the issue as follows:

frame <- monet.frame(conn,"select * from xyz.tablea")

This trick also works with CamelCased table names. For the next version, I am planning to fix the issue.
