Hello, I am using RmySQL and would like to iterate through a few queries.
I would like to use sprintf but I think I'm having problems mixing and matching the sprintf syntax and the SQL regex. I have checked my sqlcmd and it works when I wan to match %MG1% but how do I iterate for i 1-72? Escape characters,? thanks in advance i<-1 sqlcmd_ScaffLen<-sprintf('SELECT scaffold.length FROM scaffold,scaffold2contig,contig2read WHERE scaffold.scaffold_id=scaffold2contig.scaffold_id AND scaffold2contig.contig_id=contig2read.contig_id AND contig2read.read_id LIKE '%MG%s%' ,i) ========= Here is my vague error message Error: unexpected input in: ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
