Hi everyone, Today i have a big problem returning a null value in a 8-byte int to MariaDB, I´m using a OOP classes, all my data files have a entity (NOT THE UML PROPOSED BY windev)... I was trying to use a Variant type but doesn´t work, the null aren´t accepted, just return 0 to MariaDB how can i pass null at 8-byte int Thanks for the help...
