Invoking the mirna2mrna() function from affycoretools generates two warnings:

Warning messages:
1: In result_fetch(res@ptr, n = n) :
  SQL statements must be issued with dbExecute() or dbSendStatement() instead of dbGetQuery() or dbSendQuery().
2: In result_fetch(res@ptr, n = n) :
  SQL statements must be issued with dbExecute() or dbSendStatement() instead of dbGetQuery() or dbSendQuery().

The result, however, seems to be OK. It would be nice, if the code in mirna2mrna() could to be changed according to the text in the warnings.

A working example follows below:

  library(affycoretools)
  library(org.Dm.eg.db)
  library(drosophila2.db)

  sigmrna.f <- c("1622906_at", "1628369_at", "1629539_s_at", "1641237_a_at")
  sigmirna.f <- c("dme-miR-14-3p_st", "dme-miR-279-3p_st", "dme-miR-286-3p_st")

  mirna.targets <- data.frame(
                     miRTarBase.ID = c("MIRT001879", "MIRT001888", "MIRT001889", "MIRT002356"),
                     miRNA = c("dme-miR-312-3p", "dme-miR-286-3p", "dme-miR-279-3p", "dme-miR-14-3p"),
                     target.gene = c("CrebA", "boss", "SP555", "EcR"), 
                     Entrez.ID = c(39682L, 43146L, 53471L, 35540L), 
                     ENST = c("FBtr0075557", "FBtr0084949", "FBtr0333534", "FBtr0086009")
                   )
  aname <- "dme_targets.tsv"
  write.table(mirna.targets, aname, sep = "\t", col.names=FALSE, row.names=FALSE, quote=FALSE)

  imap <- mirna2mrna(miRNAids=sigmirna.f, miRNAannot=aname, mRNAids=sigmrna.f, 
                     orgPkg="org.Dm.eg.db", chipPkg="drosophila2.db",
                     sanger=FALSE, miRNAcol=2, mRNAcol=5, transType="ensembl")
  print(imap)
  # $`dme-miR-279-3p`
  # [1] "1629539_s_at" "1641237_a_at"

  # $`dme-miR-286-3p`
  # [1] "1628369_at"

Thanks for pointing that out. It's not an error, just a warning that RSQLite doesn't like you to use dbGetQuery for calls to the DB that don't return values. I've switched it to use dbExecute in devel.
