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

    Just for completeness, I'll add an answer based on Hadley's comment. The DBI package now has the function sqlInterpolate which can also perform this. It requires a list of function arguments to be named in the sql query that all must start with a ?. Excerpt from the DBI manual below

    sql <- "SELECT * FROM X WHERE name = ?name"
    sqlInterpolate(ANSI(), sql, name = "Hadley")
    # This is safe because the single quote has been double escaped
    sqlInterpolate(ANSI(), sql, name = "H'); DROP TABLE--;")
