According to Wikipedia, the bulk insert is a process or method provided by a database management system to load multiple rows of data into a database table. If we adjust this explanation to the BULK INSERT statement, the bulk insert allows importing external data files into SQL Server.
Assume that our organization has a CSV file of 1.500.000 rows, and we want to import it to a particular table in SQL Server to use the BULK INSERT statement in SQL Server. We can find several methods to handle this task. It could be using BCP (bulk copy program), SQL Server Import and Export Wizard, or SQL Server Integration Service package. However, the BULK INSERT statement is much faster and potent. Another advantage is that it offers several parameters helping to determine the bulk insert process settings.
Let’s start with a basic sample. Then we will go through more sophisticated scenarios.
