SQL Server 2012是否支持BulkCopy？该功能是否仍可使用？

Absolutely! SQL Server 2012 fully supports BulkCopy functionality—it’s a staple feature for handling large-scale data imports efficiently, and there’s no restriction on using it in this version.

Let me break down what this means for you:

• SqlBulkCopy (for .NET applications)：This class in the System.Data.SqlClient namespace has been around since .NET Framework 2.0, and it works seamlessly with SQL Server 2012. It lets you bulk-load data from sources like DataTables, DataReaders, or even custom sources directly into SQL Server tables with minimal overhead. Here’s a quick snippet to illustrate:

  using (SqlConnection connection = new SqlConnection(connectionString))
  {
      connection.Open();
      using (SqlBulkCopy bulkCopy = new SqlBulkCopy(connection))
      {
          bulkCopy.DestinationTableName = "YourTargetTable";
          bulkCopy.WriteToServer(yourDataTable);
      }
  }
  

• BULK INSERT command (T-SQL)：If you prefer working directly with T-SQL, SQL Server 2012 also supports the BULK INSERT statement. This lets you import data from a file (like CSV, TSV) directly into a table, which is perfect for server-side bulk operations. Example:

  BULK INSERT YourTargetTable
  FROM 'C:\YourDataFile.csv'
  WITH (
      FIELDTERMINATOR = ',',
      ROWTERMINATOR = '\n',
      FIRSTROW = 2 -- Skip header row if present
  );
  

Both methods are fully supported in SQL Server 2012, and they’re optimized for performance—way faster than inserting rows one by one when dealing with large datasets.
