Critical bug in version 9.4.4, reverting to version 9.4.3

Post by jjmorlan » Thu 19 Aug 2021 13:17

In Delphi Rio 10.3.3, I have developed an App that works well in Android Version 9 until I update to the SDAC 9.4.4 version, in this version I code like the following do not work

In a button I add the following code

Code: Select all

sequence:= sequence + 1;
MSQuery1.params[0].value:= 1;

MSQuery1code_id.value:= sequence;
MSQuery1last_name.value:= 'Robert';
This line of code will only work the first time, the next time you run it it will generate memory access error.

For this code not to be an error, this part of the code must go as follows:

Code: Select all

MSQuery1.FieldByName('code_id').Value:= sequence;
MSQuery1.FieldByName('last_name').Value:= 'Robert';
Horrible, right ?

Since I updated to the SDAC 9.4.4 version, the application that has worked well began to present inexplicable errors. I wasted precious time from work trying to find an explanation. Uninstall version 9.4.4 and went back to version 9.4.3 and returned everything works perfect.
