🎬 [How to insert multiple rows or massive data inserts with C #, Windows Form and SQL Server - Parameterized SQL Instructions (Transact-SQL) vs DataAdapter vs. Bulk Insert vs. Table-Valued Parameters vs. Sql Bulk Copy]

Ways / methods to insert multiple rows
There are many ways to make massive insertions, with good practices, good performance and efficiency, for example:

-By parameterized SQL instructions with multiple INSERT statements and inserted individually in each loop and wrapped in a single transaction (See previous example).
-By parameterized SQL instructions with multiple INSERT statements and inserted in a batch outside the loop in a single transaction, however, it is limited to 2100 parameters.
-By SQL instructions parameterized in a single INSERT statement and inserted in batch in a single transaction. However, it is limited to 2100 parameters and 1000 row inserts.
-By the Update () method of the DataAdapter class.
-Through Table-Valued Parameters (TVP), minimum startup cost and you can insert up to 1000 rows with good performance and speed, after exceeding one thousand rows the performance decreases.
-By Bulk Insert, higher startup cost, likewise performance decreases rapidly as the rows increase.
-By SQL Bulk Copy, it is simply necessary to load the data from a DataTable or DataReader, you can insert up to 700 thousand rows with considerable performance, then the performance decreases.
-By Entity Framework, Dapper, or other ORM, which makes things easier and simpler.
 
By using parameterized SQL Instructions with multiple declarations or batch declarations to perform small row insertion operations (less than 100 rows), good performance and efficiency are obtained instead of Bulk Insert, Table-Valued Parameters or Sql Bulk operations Copy, but these methods are recommended to insert hundreds or thousands of rows. However, performance decreases as the rows increase.
