RODBC using Data.Frame in a Join on sqlQuery()

Question

Is there a way to use a data.frame in JOIN condition using sqlQuery()?

I\'m connecting to SQL server using RODBC and need to limit the inital result set against a da

Answer 1

To reference R data in a SQL query over RODBC, your options are:

1. Read the SQL data into R then do your manipulations there
2. Use paste or a similar command to print relevant contents of your R dataframe into your SQL query
3. Pass the relevant part of your R dataframe into SQL first in a temporary or permanent table and then use SQL do join on it

In the case of #2 join would not be the appropriate SQL operation however, since you're passing a string instead of a table. Try using where, in, and clauses like that which will work on a string of names in your query as opposed to a table.
