Hi Marc, I found the place where this issue generates. When we try click on Table->Structure->Column->Change link it goes to the tbl_alter.php file and within that the "append_fields_form" is process by using tbl_properties.inc.php file. At line number 325 in tbl_properties.inc.php "PMA_getSupportedDatatypes(true, $type_upper);" function is call to get the table type select options. You can find at line 3118 in "PMA_getSupportedDatatypes(true, $type_upper);" the option selection is set as *if ($selected == $value) {* * $retval .= "<option selected='selected'>$value</option>";* * } else {* * $retval .= "<option>$value</option>";* * }* But if you use an echo you can see that *$selected contains *VARCHAR(45) as the value and *$value contains *VARCHAR as the value. So when we try to edit the tables which are having VARCHAR type columns it does not select the value at the options. I can modify the logic by splitting the *$selected *by "(" and solve the issue. Is there any better solution you can suggest. If there any please let me know. Thank you.
