This is an old thread but have any of you tried removing all quotes conveniently added by the tool?
#NIM102585 In ArcGIS Desktop 10.2.2, the quotes have to be either removed or modified in the Expression column of the Make Query table tool to run the tool successfully.
Hi guys, I solved this issue by right-clicking on the layer, click on properties then source, edit the query, remove everything in the query box then double click on the list of tables (The table that you are using), click on validate, once the validate button is disabled then click on next, select the unique identifier field then OK and that should fix it.
