When preparing to transfer data from SAS to SQL Server via SAS/ACCESS, you must have a SQL Server destination table into which to deposit SAS data. SAS/ACCESS and PROC SQL permit you to create the table on the fly so that it conforms to an existing SAS dataset. With this appr...

Q21) What is the difference between reading data from an external file and reading data from an existing dataset? The main difference is that while reading an existing data set with the SET statement, SAS retains the values of the variables from one observation to the next. Whereas when readi...
