Hi, Can you extract data from a SQL server table based on parameters already in R? For example I have a list of unique patient IDs with latest hospitalisation date which I've processed in R. I need to join this data to other tables in SQL server. The tables in SQL server are too large to import without reducing the number of records. I do not have write access to the SQL server.
mMPILatestHosp #this is my data frame of patients with unique IDs (ID) and most recent date (EVENDate) The select query is easy query<-"select * (plus columns in mMPILatestHosp) from Pharm2011 where....#This is where I want to insert mMPILatestHosp$ID in the where clause" I'm new to R so would appreciate your help.
