The Microsoft Jet database engine could not execute the SQL statement because it contains a field that has an invalid data type. (Error 3169)

You tried to execute an SQL statement that contains a field that has an invalid field data type.

Possible causes:

• You included a Memo or OLE Object field in an expression where it is not allowed.
  
  
• You included a numeric aggregate function, such as Sum or StDev, that tried to perform a calculation on a Text field. Choose a different aggregate function.
