Hello,
After a (bad) first try some months ago, I'm trying again to use RODBC
package instead of DBI+RMySQL packages to populate MySQL database.
The main command is
sqlSave(channel, data_df, tablename, append=T, rownames=FALSE,
colnames=FALSE, fast=FALSE, varTypes=vartypes)
where data_df is the
I've just tested with 12 figures instead of 13. And it works ...
But I'm not able to modify these numbers as they are codes given by other
guys (and women as well) to distinguish equipments.
And I thought the limit with R was 15 digits and not 13.
Is it a (bad for me) special feature of the
Why don't you read/write this field as a character string? Pretty common for
codes.

In fact, I always use a string for ID variables because you can get
some funky matching errors due to mismatches in precision.
Bill Gould at Stata Corp said this well in a recent blog post
1. Use theory to check IDs if they are numeric
One way the id variable can become corrupted is if it is not
I spent all the day on this problem and I've just finally found a solution:
with options(digits=13), it now works.
If I hadn't found this, I would have used the solution of Renaud (but not
very convenient to me).
Nice end of day,
(Happy) Ptit Bleu.

I'm trying to export a data frame to Excel using the RODBC sqlSave function. I
don't want the colnames, so I use the colnames=F option. Unfortunately, the
column names still show up as the first row in my spreadsheet. If I set the
colnames=T, then the column names show up in BOTH rows 1 and 2.
Hello,
How can I tell RODBC to scan all the records of an xls file to determine the
data type? If the first n records happen to be empty Rodbc assumes a character,
and any numbers are made NA. And if, for instance, the first n records
contain
numbers, and later they also contain characters,
This is not a decision being made by RODBC... it is in the Microsoft ODBC
driver for Excel. If you really want to know more, you can read

but the best solution is to take your data out of Excel and only use xls/xlsx

the

I've had the same problem and ended up using the xlsReadWrite package. It
takes more time to import a sheet but does have the colClasses command.
Following your example:
library(xlsReadWrite)
read.xls(testtable, sheet = sheet1, colClasses=character)
should worked, it did for me

Hi All,
I'm using RODBC to tap into MySQL on a remote server. It appears like
the connection is successful: I can see all tables and columns in my
database. However, queries return zero lines, including queries I've
verified as functional and non-empty by entering them directly in
MySQL.
