Hi,
first of all: I am new to R. Anyway, I would like to include sql
files in
my r-script, which I load via source("scriptname") in the CLI.
The sql files (i.e. "stmt.sql") contains select statements with
joins, line
breaks, various characters, they can be quite long.
My question is, is there a way to include external sql files for further
processing? Or how can I include them. I tried it with source(),
read.table
but I could get it to work.
SQL is a different language from R. You shouldn't expect source() to
work.
You can process SQL using RODBC or various other database packages,
e.g. RSQLite. They send the SQL statements to a database for processing.

Thank you,
but I already use the ODBC R-library for connecting to the MySQL Server.
The problem I have is to put the sql statement into my script.R, or
better to say to load it into my script. SInce some sql-statements ar
quite long, using many line-breaks to keep the statement readable, using
control structures like if and case I could not manage to work it yet.
Because I do not like to format (to put it in one line, only) my sql
statement eacht time I process it with R.
You need to give a simple example of what the problem is if you want
more help.
