Insert - Output Identity Value

Problem

You need to output newly generated identity value but SqlBulkCopy do not support it.

Solution

Map your identity column with output direction.

var bulk = new BulkOperation(connection);

bulk.ColumnMappings.Add("CustomerID", ColumnMappingDirectionType.Output);
// ... mappings ...

bulk.BulkInsert(dt);

Flexibility

You can also output concurrency column (Timestamp) or any other column values. All kind of mapping direction are supported including "Formula" to use with a SQL Formula.

Entity DataSource / Lambda Mapping

Problem

You have a list of entity to insert but SqlBulkCopy doesn't support entity and lambda expression mapping.

Solution

Create a generic bulk operations with your entity type and use lambda expression for your column input, output and primary key mapping.

var bulk = new BulkOperation<Customer>(connection);

bulk.ColumnInputExpression = c => new { c.Name,  c.FirstName };
bulk.ColumnOutputExpression = c => c.CustomerID;
bulk.ColumnPrimaryKeyExpression = c => c.Code;

bulk.BulkMerge(customers);

Maintainability

Get rid of hardcoded string and use strongly-typed lambda expressions.

AutoMapping & Case Sensitivity

Problem

You have a DataTable which columns name match name in the database but SqlBulkCopy throw an error because name match are case insensitive.

Solution

Turn off case sensitivity with IsCaseSensitive property.

var bulk = new BulkOperation(connection);

bulk.IsCaseSensitive = false;

bulk.BulkMerge(dt);

Readability

Remove useless code which would have required to create your own mapping and keep the essentials.
