It basically was the connection error.

i manage to solve the connection issue on one table but now found another issue on another table.

The initial intention is migrate the source data to staging. The source are sql 2000, they have some attachment as an image type Then we have the Failed to retrieve long data for column issue when we just do the select * from tableA

Then I try to do the select cast(ImageTypeColumn) as varbinary(8000) from tableA now it work for those data which is not exist 8000 byte

But unfortunately in the another table, there exist some rows data length is huge. Thus it failed again when we do the select cast(ImageTypeColumn) as varbinary(8000) from tableA

In Microsoft SQL Server 2000 and earlier versions, the varbinary data type had a maximum limit of 8,000 bytes. To store up to 2 GB of binary data the image data type needs to be used instead.

Finally i found a solution on that. Using ADO.net Source instead of using the OLEDB.net Source
