How to perform bulk insert operations in SQL Server?

In SQL Server, you can perform bulk insert operations using the following methods:

1. Perform batch insertion operations using the INSERT INTO VALUES statement. For example:

INSERT INTO table_name (column1, column2) 
VALUES (value1, value2),
       (value3, value4),
       (value5, value6);

1. Perform bulk insert operations by combining the INSERT INTO SELECT statement with UNION ALL. For example:

INSERT INTO table_name (column1, column2) 
SELECT value1, value2
UNION ALL
SELECT value3, value4
UNION ALL
SELECT value5, value6;

1. Import data from an external file into a database table using the BULK INSERT statement. For example:

BULK INSERT table_name 
FROM 'file_path'
WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '\n');

The above are some commonly used methods for performing batch insert operations, the specific method used depends on the data source and requirements.
