[R] Error while conecting to database.

[Manish Gupta]

Hi, 

I am getting following error message while retrieving records from mysql.

*Error in if (count > 0L) { : missing value where TRUE/FALSE needed
Calls: <Anonymous> -> do.call -> <Anonymous> -> <Anonymous>
Execution halted*


con2 <- dbConnect(MySQL(), user="XXX", password="",dbname="yyyy",
host="XXX.X.X.X")
#if(nchar(disname) == 2)
{
    disQuery= "select Desc from Tablename where Tableanem.field = " 
    cat(paste("*********",disname,"*************","\n",sep=""))
    disQuery<-paste(disQuery, "'", disname ,"'", sep = "")
    cat(disQuery,"\n")
    cat(paste("\\textbf{",Col3[i],"?}\n",sep=""))
    cat("\\leavevmode","\n")
    cat("\\newline","\n")  
    #cat(disQuery,"\n")
    
    #print(dbListTables(con2))
    disres <- dbSendQuery(con2, disQuery)
    dout <- fetch(disres, n = 10000)
    dataout <- ifelse(is.na(dout), "-" ,dout)
    cat(paste(dataout),"\n")                              * // getting error
message here*
    
}
dbDisconnect(con2)


May i know why I am getting above error message. 

Regards
