FileTable Support

For writing to a Microsoft SQL Server FileTable, see Microsoft Excel - Alteryx Driver.


  • Maximum Columns In Table: 1024

  • Maximum Column Name Length: 128 characters

  • Maximum Row Size: 8060 bytes ( does not include LOB size )

LOB or VARBINARY data must all be at the end of the select. If the user enters a SQL statement that doesn't have them at the end of the statement they get a warning, "A blob or binary field has been detected in your query. The data in this field will be returned as NULL unless it is moved to the end of your select statement.". Selecting the table on the Tables tab will move all LOBs to the end.

There is a limit for SQL Server for varchar(max) of 16777216 characters (read and write). Data above this limit is truncated.
