The select statement that specified a view could be slightly changed when the view was saved in a frm file. In particular references to an alias name in the HAVING clause could be substituted for the expression named by this alias. This could result in an error message for a query of the form SELECT * FROM <view>. Yet no such message appeared when executing the query specifying the view. mysql-test/r/having.result: Adjusted results after fixing bug #19573. mysql-test/r/view.result: Added a test case for bug #19573. mysql-test/t/view.test: Added a test case for bug #19573.
