Hello
Trying to use Copy Activity to copy data from Azure SQL Server to DataLake via Pipeline.
Most of the tables are successful but some failed with the following error:
Activity failed because an inner activity failed; Inner activity name: Copy_s2q, Error: ErrorCode=DeltaNotSupportedLogicalType,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=The logical type TimeSpan is not supported in Delta format. Reason: Cannot find supported delta type for logical type TimeSpan,Source=Microsoft.DataTransfer.ClientLibrary,'
Any ideas on where to start looking to troubleshoot?
Output from CopyActivity:
{
"copyDuration": 9,
"errors": [{ "Code": 21450, "Message": "ErrorCode=DeltaNotSupportedLogicalType,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=The logical type TimeSpan is not supported in Delta format.

Would you mind filling a support case for this? We'll need engineering to track this one down. Thank you!
Hi there,
Did this issue ever get looked at as I've hit the same error with a 'Timespan' source column. Even if try to cast the column as a varchar or even remove the Timespan column from the SELECT statement, I still hit the same error: "Cannot find supported delta type for logical type TimeSpan"
Hey there DaveM92,
After chatting to the support team, they advised mapping the data type to a 'string' as part of the initial load.
In the copy wizard, on the mapping tab, I manually assigned the data type. Thankfully I only have 3 tables that this affects, so not a train smash, but not ideal either.
