I'm having some difficulty inserting a data frame into a mySql database using RODBC. Below is the code I'm using:

data <- data.frame(analysedDataID=c(1,2,3), plateWell=c("a","b","c"), screenPlateOrder=c(1,2,3), wellData=c("A","B","C"))

con <- odbcConnect(DSN, uid="user_id", pwd="some_password")
query <- sqlSave(con, data, tablename = 'wellAnalysedDataTable', rownames=FALSE, append=TRUE)

When I try to execute this I get the following error message:

Error in odbcUpdate(channel, query, mydata, coldata[m, ], test = test,  : 
missing columns in 'data'

Here is the specific table I'm trying to insert the data into:

+------------------+-------------+------+-----+---------+-------+
| Field            | Type        | Null | Key | Default | Extra |
+------------------+-------------+------+-----+---------+-------+
| analysedDataID   | int(10)     | YES  |     | NULL    |       | 
| plateWell        | varchar(10) | YES  |     | NULL    |       | 
| screenPlateOrder | int(10)     | YES  |     | NULL    |       | 
| wellData         | varchar(30) | YES  |     | NULL    |       | 
+------------------+-------------+------+-----+---------+-------+

I am just really confused at this point as I've read the documentation over and over again but just can't get this to work. Any help would be greatly appreciated!

Cheers!

Thanks! I added the changes you suggested and there does not seem to be a problem with the case anymore. However I keep getting the following error message: 

'index column(s) analysedDataID plateWell screenPlateOrder wellData not in data frame'

The statement I'm executing that generates this is:

sqlUpdate(con, data, tablename="wellAnalysedDataTable", index=c("analysedDataID", "plateWell", "screenPlateOrder", "wellData"))

This doesn't make any sense to me as the columns a

mysql r rodbc
