I have a .csv that has 4 columns that I need to insert data from two of those columns into two different tables. Two of those columns I need to join to two different tables to do insert statements into the two tables. Anyone know how to do this?

    The simplest way to do what you describe it to import the CSV into a "staging" table, and then write TSQL to do what you need to do.

    Yes, as Tom says, for a solution without SSIS (which I don't know myself), you need to import the file into a table, and then work from the table.

    If the file is located so that you can access it from SQL Server, you can use the BULK INSERT command.

    If it is not, you may be able to import it with the command-line utility BCP.

    We also need which version of SQL Server you are using. What's the output of "SELECT @@version"?

    Hi @MR BILL ,

    1. Could you please share the example data in your .csv file and your desired output data?
    2. May I know if you installed the SQL Server Data Tools (SSDT) for Visual Studio ?
      If so, please create new Integration Services project and package.

    3. Then we can drag a Data Flow Task in ssis package. We can use Flat File Source, Multicast Transformation and OLEDB Destination in Data Flow Task to load data from a .csv file to two sql tables.
