Re: [R] Unrecognized token
Maybe you should escape the single quotes something like ' id ' ?

Re: [R] Unrecognized token
Look at the query strings your code produces: with(list(id=c(1234,abcd)), paste(paste(select * from tbl_user where student_id = , id, sep=), order by date_time, sep=) ) [1] select * from tbl_user where student_id = 1234 order by date_time [2] select * from tbl_user where student_id = abcd order by date_time I suspect that the abcd should have quotes around it. If student_id is stored as string data the 1234 should probably also have quotes around it. Replace id with \, id, \ and you may get a query that works.

Re: [R] Unrecognized token
Thanks William, actually, the combination that works is: with(list(id=c(1234,abcd)), paste(paste(select * from tbl_user where student_id = '78789D', sep=), order by date_time, sep=), maybe I should try to replace double quotes with single (opposite of what I was doing...)

Re: [R] Unrecognized token
id - c(21328,78789D) query - paste(paste(select * from tbl_user where student_id = , id,sep=), order by date_time, sep=) query [1] select * from tbl_user where student_id = 21328 order by date_time [2] select * from tbl_user where student_id = 78789D order by date_time Now, does the second string look like valid SQL to you? In particular, the 78789D is a problem. On the other hand... query - paste(paste(select * from tbl_user where student_id = ', id,sep=), ' order by date_time, sep=) query [1] select * from tbl_user where student_id = '21328' order by date_time [2] select * from tbl_user where student_id = '78789D' order by date_time As others have pointed out, in this case escaping does not appear to be key to getting valid SQL syntax... but looking at the query before shipping it off to a database engine seems to me to be an obvious technique you should learn.
