将所有 CSV 从本地驱动器上的路径加载到 AzureSQL DB w/Auto Create Tables

Question

I frequently need to validate CSVs submitted from clients to make sure that the headers and values in the file meet our specifications. Typically I do this by using the Import/Export Wizard and have the wizard create the table based on the CSV (file name becomes table name, and the headers become the column names). Then we run a set of stored procedures that checks the information_schema for said table(s) and matches that up with our specs, etc.

Most of the time, this involves loading multiple files at a time for a client, which becomes very time consuming and laborious very quickly when using the import/export wizard. I tried using an xp_cmshell sql script to load everything from a path at once to have the same result, but xp_cmshell is not supported by AzureSQL DB.

https://learn.microsoft.com/en-us/azure/azure-sql/load-from-csv-with-bcp

The above says that one can load using bcp, but it also requires the table to exist before the import... I need the table structure to mimic the CSV. Any ideas here?

Thanks

If you want to load the data into your target SQL db, then you can use Azure Data Factory[ ADF ] to upload your CSV files to Azure Blob Storage, and then use Copy Data Activity to load that data in CSV files into Azure SQL db tables - without creating those tables upfront .

ADF supports 'auto create' of sink tables. See this , and this
