Functions

There is only one core function in upsertR: upsert(), which lets you upsert a dataframe to a target SQL server. The below example will upsert data df to SQL server connection con to target table ods.events.

upsert(connection = con,    # SQL server connection string
       dataframe  = df,     # input dataframe
       schema     = ods,    # Target schema name on SQL server
       table      = events, # Target table name on SQL server
       delete     = TRUE)   # specifies whether to delete old ID's not present in input DF. TRUE deletes
