Hello,
I have 3 tables in cascade and it seems that it isn't possible to retrieve the data from the first level.

In the tablegrid output of the search, I cannot retrieve the sex of the user.(I have 4 records represented instead of 2).
If someone could look at this simple project and help me to solve the issue.
Many thanks,
YvesI tray fix your project maybe can help you. you must add calculated field in table user

Hello Agusecc,
I don't use Fastreport very much so I'm probably not the best person to ask, but it looks like it's objecting to the format of the dates that are being passed through.
I'm sure there is a way to correct this within FastReport but I prefer to change it within MVD (because it's what I understand a bit better).
So I've created calculated fields for all of your date fields, formatting them as 'text' in the format dd/mm/yy.
I then pass the calculated fields through to FastReport and use them in your reports rather than the original date fields.
I've created calculated fields for most of your date fields but I may have missed a couple (I was in a rush!) but I'm sure you can follow the logic.
Derek.
Derek, Thank you very much. I really appreciate your kindness to help in this forum. and now i got the solution for my project improvement. May you always be successful in every way of your life

Hi Yandi,
As Sibprogsistem wrote, if you want to see 'age' in the tablegrid, use a calculated field.
If you also need to see 'age' change real-time on the form where you enter the date of birth, you also need to use a script.
Perhaps try it like this (see attached).
Derek.
How is filter old '0' from tablegrid in form3?
I want to hidden 0 age from tablrgrid when searching birthday...
thanks you
