write to that table irrespective

RODBC: sqlSave leave primary key and other columns null
I have an existing table, and I am trying to use sqlSave to append
additional rows to this database. I omit the primary key, which is a
uniqueidentifier type (MS SQL), so that the database can populate that

consulta por varTypes de sqlSave en RODBC
Hola Javier, si no estoy entendiendo mal, lo q deseo hacer no se trata de

Hi,
I am having trouble to write/create a table, which has
a date field. I want to create a stock price table,
which has fields of ticker, date, price. First, I

Hi Michael,
Here is the result of my first testing:

Sorry, I should have given a more precise description: by default in R

odbcPrimaryKeys(0, table)
a Dr. Watson occurs, because table does not give a table name.
However, it is always a good idea to prevent Dr. Watsons, even if it is
