MS Access - 255 Column Limit. Published 09/12/2002 01:02 PM | Updated 11/22/2011 06:19 PM. Does Microsoft Access have a limit on the number of columns that can be in a table? Microsoft Access (w/ the JET Engine) is able to display no more than 255 columns in a table.
If the table contains one or more XML indexes, the clustering key of the user table is limited to 31 columns because the XML column is added to the clustering key of the primary XML index. In SQL Server, you can include nonkey columns in a nonclustered index to avoid the limitation of a maximum of 32 key columns.
