You are attempting to edit a table that contains a renamed column. This is not allowed. This error would occur, for example,
if you attempted to edit the result of the following query (which changes the name of the e_no column to xemp):
Restriction: This topic applies to Windows environments only.
SELECT xemp = e_no FROM tutorial.employee;
When you edit the result, SQLWizard attempts to update xemp, which doesn't exist in the table.
To edit the result, reissue the query without renaming the column.
