A primary key or index cannot be created on columns with a datatype of <Datatypename>. (Visual Database Tools)

A column's data type defines what kind of information can be stored in a column. Some data types such as TEXT or Image cannot be used in an index because servers will not allow indexes on these types of data.

For more information, see Creating Indexes (Database Engine).
