问题 I have an azure app on the cloud with a sql azure database. I have a worker role which needs to do parsing+processing on a file (up to ~30 million rows) so i can't directly use BCP or SSIS. I'm currently using SqlBulkCopy, however this seems too slow as I've seen load times of up to 4-5 minutes for 400k rows. I want to run my bulk inserts in parallel; however reading through the articles on importing data in parallel/controlling lock behaviour, it says that SqlBulkCopy requires that the table

问题 Can I use sqlbulkcopy with Azure SQL Paas? I have an app that does bulk copy to a database and we are testing it with SQL PaaS. It appears to be failing on the SQLBulkCopy. I thought I read this is not supported somewhere but do not see it in the Azure SQL documentation. Is this still a limitation? Where is that documented? I am using .net code to do the bulk copy (not SSIS or any other tool), it is a .net app, if it matters. 回答1: Short answer is, yes, you can use SQLBulkCopy to insert data

问题 I am using SqlBulkCopy (.NET) with ObjectReader (FastMember) to perform an import from XML based file. I have added the proper column mappings. At certain instances I get an error: Failed to convert parameter value from a String to a Int32. I'd like to understand how to 1. Trace the actual table column which has failed 2. Get the "current" on the ObjectReader sample code: using (ObjectReader reader = genericReader.GetReader()) { try { sbc.WriteToServer(reader); //sbc is SqlBulkCopy instance
