Has there been a resolution to this problem? I am getting the same error when trying to use the Make Query Table tool in ArcMap 10.0 with a feature layer and a separate attribute table which are both in the same personal geodatabase. I am trying to duplicate features in a feature class to match all the entries in an attribute table, joining on a common variable. I got no errors, just an empty output layer when I ran it first, i.e. all the fields were there but there were no features at all.
Then I ran verify on my expression (FeatureLayerName.Legal_Id = AttributeTable.Legal_Id), and it gives the error:
"There was an error with the expression. General function failure. [AttributeTable] Too few parameters. Expected 1."
