从链接服务器复制表

Question

I was trying to copy a table from a view in linked server with the following script:

SELECT 
    [order_no]
    , [cust_code]
    , [order_date]
    , [order_status]
    , [reference]
INTO dbo.Sales
FROM [BIT].[bit].[BI].[sales_order]

I got the error below:

Cannot get the data of the row from the OLE DB provider for linked server "BIT". Could not convert the data value due to reasons other than sign mismatch or overflow.

The script runs well if I remove the [reference] column. I have checked the data type and it is matched.

What can I do if I really want the reference column to be in the table? I have tried to copy only the reference column and it is failed as well with the same error message.

See this stackoverflow post which shows how to find invalid characters in SQL fields

For your table this is what you'd use to find invalid characters in the reference field:

select [reference],
  patindex('%[^ !-~]%' COLLATE Latin1_General_BIN,[reference]) as [Position],
  substring([reference],patindex('%[^ !-~]%' COLLATE Latin1_General_BIN,[reference]),1) as [InvalidCharacter],
  ascii(substring([reference],patindex('%[^ !-~]%' COLLATE Latin1_General_BIN,[reference]),1)) as [ASCIICode]
from  dbo.Sales
where patindex('%[^ !-~]%' COLLATE Latin1_General_BIN,[reference]) >0
