SQL Server RODBC Connection

Question

Does anyone have a connection string example for using RODBC and connecting to MS SQL Server 2005 or 2008.

Thank you.

Answer 1

Try to use RSQLS package: https://github.com/martinkabe/RSQLS

Very fast pushes data from data.frame to SQL Server or pulls from SQL Server to data.frame.

Example:

library(devtools)
install_github("martinkabe/RSQLS")
library(RSQLS)

cs <- set_connString("LAPTOP-USER\\SQLEXPRESS", "Database_Name")
push_data(cs, dataFrame, "dbo.TableName", append = TRUE, showprogress = TRUE)
df <- pull_data(cs, "SELECT * FROM dbo.TableName", showprogress = TRUE)

This solution is much faster and more robust than RODBC::sqlSave or DBI::dbWriteTable.
