“read.sql” function in R: Using R as an SQL browser?

Question

I have a large .sql file, created as a backup from a MySQL database (containing several tables), and I would like to search elements within it from R.

Answer 1

Would this return what you seek (which I think upon review you will admit is not yet particularly well described):

 require(RMySQL)
 drv <- dbDriver("MySQL")
 con <- dbConnect(drv)
 dbListTables(con)
 # Or
 names(dbGetInfo(drv))

If these are just source code than all you would need is readLines. If you are looking for an R-engine that can take SQL code and produce useful results then the sqldf package may provide some help. It parses SQL code embedded in quoted strings and applies it either to dataframe objects in memory or to disk-resident tables (or both). Its default driver for disk files is SQLite but other drivers can be used.
