sql - Data Truncation issue while importing excel from Azure Blob storage to Sql Server

Question

I'm trying to import the below excel file present in the azure blob storage into sql server

EXCEL File

Query

SELECT * 
    FROM OPENROWSET(
        BULK 'container/testfile.xlsx', 
        DATA_SOURCE = 'ExternalSrcImport',
        FORMATFILE='container/test.fmt', FORMATFILE_DATA_SOURCE = 'ExternalSrcImport',
        codepage = 1252,
        FIRSTROW = 1
        ) as data

Format file

10.0  
4  
1       SQLCHAR       0       7       "\t"     1     DepartmentID     ""  
2       SQLCHAR       0       100     "\t"     2     Name             SQL_Latin1_General_CP1_CI_AS  
3       SQLCHAR       0       100     "\t"     3     GroupName        SQL_Latin1_General_CP1_CI_AS  
4       SQLCHAR       0       24      "\r\n"   4     ModifiedDate     ""  

Illustration of Format File

when I execute the query, I'm getting the below error

Msg 4863, Level 16, State 1, Line 210 Bulk load data conversion error (truncation) for row 1, column 1 (DepartmentID).

looks like field terminator in the format file is not working, any ideas to import the file ?

Answer 1

您的格式文件表示导入制表符分隔值文件，但在源路径中您指的是 xslx 文件。
Xslx 文件是多个 XML 文件的 ZIP 存档，批量导入将无法处理它。要打开它，您需要使用 Microsoft Jet 或 ACE 驱动程序，这里有一些示例： using-openrowset-to-read-excel。在处理文件之前，您需要将文件从 Blob 存储下载到本地磁盘。您可以使用 SQL 代理或 SSIS 来下载它。

其他选项是将您的数据保存为 CSV 或制表符分隔文件，并直接从 blob 存储加载。
