In SQL, bulk operations can be performed using batch insert statements (INSERT INTO), which allows multiple records to be inserted into a database table at once. Here are some common methods for batch insert in SQL.

  1. You can insert multiple records by using multiple INSERT INTO statements within a single SQL statement. Each INSERT INTO statement inserts one record.
INSERT INTO table_name (column1, column2, ...)
VALUES (value1, value2, ...),
       (value1, value2, ...),
       ...
  1. You can use the INSERT INTO SELECT statement to insert records from one table into another table.
INSERT INTO table_name (column1, column2, ...)
SELECT column1, column2, ...
FROM source_table
  1. Combining multiple records using INSERT INTO VALUES statement and UNION ALL operator: You can include multiple INSERT INTO VALUES statements and combine them together using the UNION ALL operator. Each INSERT INTO VALUES statement inserts one record.
INSERT INTO table_name (column1, column2, ...)
VALUES (value1, value2, ...)
UNION ALL
VALUES (value1, value2, ...)
UNION ALL
...

The above are several common methods for SQL batch insertion, you can choose the appropriate method based on your specific needs.
