I am in the midst of creating a program that reads data from an SQL table, changes it via code in VB, and then stores it. Upon completion of the program, the temporary table is looked at and all rows that have the same email address are aggregated (a Message Column is combined for all those) and a single entry is written to an SQL table that one at a time sends out an email.

Time is of the essence for this program, so the quicker it is done the better.

The question is, should I create a table in SQL to serve as the temporary table, or should I use DataSets/DataTables and keep the Temporary table in memory while hte program is running.

Thanks for your time in advance,
Greg

    I’d use a DataTable/DataSet:

    • A SQL Server temp table will require a persistent connection to the database
    • The DataTable/DataSet may “live” for a fairly long time. The SQL Server could reboot itself during this
    • “time is of the essence” means local cache in a DataTable/DataSet
