You are misusing SQL variable substitution. Just embed the list in the SQL statement itself.

paste("SELECT * FROM this_table WHERE this_column IN (", paste(org_table$id, collapse=TRUE),")",sep="")

Better yet, use a SQL join so you can do this sequence in one SQL statement.

Hello,


The code below works fine up until I try to use the "IN" statement in
the last line. The proper SQL format is:

SELECT * FROM this_table WHERE this_column IN (1,2,3,4,5)

But, I think I may be getting something like:

SELECT * FROM this_table WHERE this_column IN c(1,2,3,4,5)

Which makes no sense in SQL. I think it may be just a matter of string
massaging, but I'm not certain. I've tried to build the query using
sprintf statements with no luck. I could not get RMySQL to do it either.
Any suggestions?


thank you,
