I have a database which is (example.sql) and I would like to read it in RStudio for further analysis, how could I do this function?
One option is using RODBC

cn <- odbcDriverConnect(connection="Driver={SQL Server};server=localhost;database=sms;trusted_connection=yes;")
and then use sqlQuery to read the lines.

I was searching already a while and still i am not sure there is any function to split string in Informix db 11.70? Should I write my own function to make my task real or I missed something?
