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] &";")
............}

The error is:

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=" & :

In addition: Warning message:
