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 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 an error, "This ODBC driver requires that all BLOB fields be at the end of the select.". A "select * from table" will move all the 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.
