Unwanted carriage returns storing dataframes with dbWriteTable
If I save a dataframe with a character-typed last column to a relational
database with dbWriteTable, the values in the last column of the
resulting table in the database will have a '\r' (carriage return)
appended. If I read back the dataframe with dbReadTable the last column
in the resulting dataframe has also '\r' appended (see protocol below).

Rmysql - dbWritetable
Dear Rusers,
I am trying to feed my database with data from a file.
But since my file (2010101000.txt) there`s no headers I am facing problem

RMySql inserts \r when using dbWriteTable
I am using R 2.8 and the latest versions of RMySQL on a Windows XP 64 bit
machine.
I was wondering if someone could help me figure out how to use dbWriteTable
without inserting \r into my table. Consider the following code snippet,
which is
run after I connect to my database.
myDFOut = dbReadTable(conn, "myDF")
print(myDFOut)

dbWriteTable in loop
Hi,
I have to write the results of a loop in a database, and
I'm using dbWriteTable(con, "output", data).
Is it possible to use something like
for(i in 1:n)
...
tmp <- sprintf("output%s", i)
dbWriteTable(con, tmp, dati)
to write in the database each table produced by each run of the loop?
if not, do you have alternative solutions?
thanks in advance

Troubles with DBI's dbWriteTable in RMySQL
I am feeling rather dumb right now.
I created what I thought was a data.frame as follows:
aaa <- lapply(split(moreinfo,list(moreinfo$m_id),drop = TRUE), fun_m_id)
m_id_default_res <- do.call(rbind, aaa)
print("==========================================")

RMySQL problem - SOLVED
Hi,
The problem was the row.names that were sent to the database and created
an primary key duplicate. Now it works fine.
BTW congratulations for the package. It copied 15300 rows by 11 columns
in less than 5 seconds, in my PIII 833 with 1 GB RAM.

SAS.xpt/STATA.dta, field descriptions, and dbWriteTable
Hello all,
I have a large database (~100MB in 13 relational
files) that made its way to me in two formats. The
files were sent in both SAS xport and STATA, thanks, I
am told, to stat-transfer. The two files, ostensibly,
contain the same data, just in different formats.
My goal: Move these files to MySQl without the help of
SAS or STATA (which I do not have).
The tools I am using are:

DBI::dbWriteTable syntax error apparently from quotes
I have been successfully using RODBC for a long time (years) to connect to
MS SQL Server from R.
This week I wanted to try using odbc but I am seeing some problems which
may be related to how I set up my driver and/or connection.
The dbWriteTable manual page gives as an example command:
dbWriteTable( pDB$con, "mtcars", mtcars[1:5,])
When I try this I get the following error

dbWriteTable with field data type
Hello,
When I do:
dbWriteTable(con, "r.BOD", cbind(row_names = rownames(BOD), BOD))
...can I specify the data types such as varchar(12), float, double
precision, etc. for each of the fields/columns?
If not, what is the best way to create a table with specified field data
types (with the RpgSQL package/R)?

Question: RMySQL bulk load/update one column, dbWriteTable()?
Hi,
I have a question reading using RMySQL trying to load one R vector into a
table column. To be more specifically, the table is there populated. Now I
add a new column and want to populate this.
Can some colleagues on this list teach me how to do this? I know how to
write one R object/table into MYSQL table using dbWriteTable. But in this
situation, I just want to do one column.
Thanks

At first, I apologize for raising a query which seems to be a stupid interpretation on my part. I am trying to learn SQLite.

RMySQL - overwrite record, not table
Hi, useR-
In RMySQL, how do I overwrite records? (equivalent to "replace" query).
For example, suppose that dat2 is a newer data.frame than dat1.
con <- dbConnect(MySQL())
res <- dbWriteTable(con, "DBname", dat1, row.names=F, append=T, replace=T)
res <- dbWriteTable(con, "DBname", dat2, row.names=F, append=T, replace=T)
This would not update/replace the

append rows to Sybase datatable using RJDBC
Hi,
Does anyone have experience using RJDBC library to write to Sybase
datatable? The jdbc driver I am using is jConnect 6.0. I can
successfully write into a new datatable, but have problem appending rows
to existing one. It either complains "Table *** already exists" or
simply overwrite the existing one. Here is the example.
