PowerShell : Copy a table from one server to another


online trading demo konto In general, a DBA like us gets requests to copy a table data from one SQL Server instance to another. In that case, a DBA first sees the amount of data present in the table and then he decides a method to transfer. Normally, a DBA selects Import Export method or SSIS and of course that is a suggested way to transfer data between two SQL Server instances.
