如何让 ADF copy polybase 简单地将一个文件从 Azure 存储复制到 Synapse 池(sql 数据仓库)
我一直收到这个错误:
Operation on target Storage to Synapse Failed: ErrorCode=FailedDbOperation,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=Error happened when loading data into sql Data Warehouse.,Source=Microsoft.DataTransfer.ClientLibrary,''Type=System.Data.sqlClient.sqlException,Message=HdfsBridge::recordReaderFillBuffer - Unexpected error encountered filling record reader buffer: HadoopsqlException: Error converting data type NVARCHAR to BIGINT.,Source=.Net sqlClient Data Provider,sqlErrorNumber=107090,Class=16,ErrorCode=-2146232060,State=1,Errors=[{Class=16,Number=107090,},],'

这是我的文件示例,gzip 压缩:

CREATE table dbo.[lineitem](
[L_OrderKey] [bigint] NULL,[L_PartKey] [bigint] NULL,[L_SuppKey] [bigint] NULL,[L_LineNumber] [bigint] NULL,[L_Quantity] [bigint] NULL,[L_dboendedPrice] [decimal](13,2) NULL,[L_discount] [decimal](13,[L_Tax] [decimal](13,[L_ReturnFlag] [varchar](64) NULL,[L_Linestatus] [varchar](64) NULL,[L_ShipDate] [datetime] NULL,[L_CommitDate] [datetime] NULL,[L_ReceiptDate] [datetime] NULL,[L_ShipInstruct] [varchar](64) NULL,[L_ShipMode] [varchar](64) NULL,[L_Comment] [varchar](64) NULL
) ;
解决方法
我建议通过在 polybase 表的开头仅保留 1 个 BigInt 列来调试此问题,如果成功则意味着第 1 列中没有存在此问题的数据,第二次调试运行时仅保留 2 个 BigInt 列然后检查。
通过这种方式,您将能够知道哪个实际列有问题,然后您可以检查您的文件是否存在任何数据问题。
让我知道这是否有帮助!
谢谢!
