Microsoft Access Operation must use an updatable query

Problem:

The aggregate functions (e.g. Min, Max etc.) of a selection query included in this update query prevent this from being executed.

Solution:

Rebuilding the required function in VBA. Here with the example Min.

Code:

Public Function eMin(strField As String, strTblOrQry As String) As Double

eMin = DMin(strField, strTblOrQry)

End Function

Use:

Use in query as follows:

- first mask the field in quotation marks and then the table or query, then separate the whole thing with a semicolon
