Unique tables are used by the database client drivers, like Microsoft Access driver for SQL Server, to build updateable queries.For a given SELECT statement, the unique table identifies the table whose row values appear at most once in the result set.When reselecting a row from a result set, the values from the key columns of the unique table are enough to identify the row.This error is raised when the server is unable to compute the unique table.
This error may be raised when the SELECT query has a UNION, GROUP BY, ROLL UP or other aggregates.Unique tables are not defined for these cases.
Re-write the query avoiding the constructs which prevent unique table computation.In most of the error scenarios, updateable result set is not implementable.
