    <p>Ok, I got a working solution now. Here's a function that maps MySQL field types to R classes. This helps in particular handling the MySQL field type date...</p> <pre><code>dbReadMap &lt;- function(con,table){ statement &lt;- paste("DESCRIBE ",table,sep="") desc &lt;- dbGetQuery(con=con,statement)[,1:2] # strip row_names if exists because it's an attribute and not real column # otherweise it causes problems with the row count if the table has a row_names col if(length(grep(pattern="row_names",x=desc)) != 0){ x &lt;- grep(pattern="row_names",x=desc) desc &lt;- desc[-x,] } # replace length output in brackets that is returned by describe desc[,2] &lt;- gsub("[^a-z]","",desc[,2]) # building a dictionary fieldtypes &lt;- c("int","tinyint","bigint","float","double","date","character","varchar","text") rclasses &lt;- c("as.numeric","as.numeric","as.numeric","as.numeric","as.numeric","as.Date","as.character","as.character","as.character") fieldtype_to_rclass = cbind(fieldtypes,rclasses) map &lt;- merge(fieldtype_to_rclass,desc,by.x="fieldtypes",by.y="Type") map$rclasses &lt;- as.character(map$rclasses) #get data res &lt;- dbReadTable(con=con,table) i=1 for(i in 1:length(map$rclasses)) { cvn &lt;- call(map$rclasses[i],res[,map$Field[i]]) res[map$Field[i]] &lt;- eval(cvn) } return(res) } </code></pre> <p>Maybe this is not good programming practice – I just don't know any better. So, use it at your own risk or help me to improve it... And of course it's only half of it: <code>reading</code>. Hopefully I´ll find some time to write a writing function soon.</p> <p>If you have suggestions for the mapping dictionary let me know :) </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
