Hi Marc,

I identified seven situations where the method PMA_sendResponseForNoResultsReturned runs.

 1-> When browsing an empty table

 2-> When executing a query on a non empty table which returns zero results

 3-> When executing a query on an empty table

 4-> When executing an INSERT, UPDATE, DELETE query from the SQL  tab

 5-> When deleting a row from BROWSE tab

 6-> When searching using the SEARCH tab which returns zero results

 7-> When changing the structure of the table except change operation

 

In the first case the $goto variable is not initialized. But in the second, third and fourth cases it is initialized to tbl_sql.php.

In the third, fourth and fifth cases the $goto variable is initialized with sql.php itself with certain other url parameters.

In the 7 th case $goto variable is set to $tbl_structure.php

But I identified all these cases send Ajax responses where $goto variable or sending header location were never used. I would like to know whether my test scenarios are comprehensive if so shall I remove the redundant code segments.
