Here’s an example that would trigger this exception: create table ( nvarchar ( 50 ) null ) var dataTable = new DataTable () dataTable. Unfortunately, it’s not very descriptive since you don’t know which part of the mapping is incorrect. SqlBulkCopy.cs#L706 for the spot where the exception gets thrown. If there is a mismatch anywhere in the DataTable, you’ll receive this exception (with possibly similar stack trace): "The given ColumnMapping does not match up with any column in the source or destination." at .AnalyzeTargetAndCreateUpdateBulkCommand(BulkCopySimpleResultSet internalResults) at .WriteToServerInternalRestContinuedAsync(BulkCopySimpleResultSet internalResults, CancellationToken cts, TaskCompletionSource`1 source) at .WriteToServerInternalRestAsync(CancellationToken cts, TaskCompletionSource`1 source) at .WriteToServerInternalAsync(CancellationToken ctoken) at .WriteRowSourceToServerAsync(Int32 columnCount, CancellationToken ctoken) at .WriteToServer(DataTable table, DataRowState rowState) Back-end: C/.NET Core, SignalR, Rx.NET, NPoco. ![]() Currently, this is the (loose) tech stack of the larger OSINT project: Front-end: React + redux. Toki pona lessons, Vollrath 46618, Mas90 database maintenance. So, below I’ll be covering how I connected. 10 micrograms equals how many grams, Parfum fleur diris, Ros barbarian build 2.1. However, the columns are case-sensitive to their DB-neighbor. I’m electing to use the NPoco micro-ORM to make the connection a little easier. It requires you to create a to provide columns and rows of data. ![]() lets you efficiently bulk-load data into a DB-table. Explicitly using SqlBulkCopy might never cause this problem since mapping is done manually, but NPoco’s usage does automatic mapping which might cause a problem.
