Proper way to pass parameters to query in R DBI

Question

In perl/python DBI APIs have a mechanism to safely interpolate in parameters to an sql query. For example in python I would do:

cursor.execute(\"SELECT * FR         


        

Answer 1

Indeed the use of bind variables is not really well documented. Anyway the ODBC commands in R work differently for different databases. One possibility for postgres would be like this:

res <- postgresqlExecStatement(con, "SELECT * FROM table WHERE value > $1", c(5))
postgresqlFetch(res)
postgresqlCloseResult(res)

Hope it helps.
