This example demonstrates a concept for inserting data into SQL Server by using Power Query’s M language. It shows a table creation script for a demo table with an identity column, a key, and a value, followed by an M query that iterates over a list of key-value pairs. The code uses `List.Accumulate` to loop through the pairs and calls `OleDb.DataSource` with a SQL `INSERT` statement for each iteration, referencing the SQLOLEDB provider to connect to a local database. The result is the total number of affected records from the inserts, though the actual inserted rows are not visualized or returned in the output.
