Hello,
 
I've got a problem in a sql query!

for(j in 1:length(criteria$Title))

{
    graphe_par<-sqlQuery(channel,"select q.type,crit.Title, r.Value from 
criteria crit, reply r,question_reply qr, question q, question_criteria qc, 
form_question fq where qr.reply=r.ID and qr.question=q.ID and qc.question=q.ID 
and crit.ID=qc.criteria and fq.question=q.ID and fq.form=4 and crit.Title=" & 
criteria$Title[j] &";")

............}


> criteria$Title
[1] Content           Logistic          Trainer           Supply            
User contribution
Levels: Content Logistic Supply Trainer User contribution


The error is:

r,question_reply qr, question q, question_criteria qc, form_question fq where 
qr.reply=r.ID and qr.question=q.ID and qc.question=q.ID and crit.ID=qc.criteria
