    • they also have - architectural, performance problems and data type loss. - Mikhail Vaysman
    • I do not understand what's wrong with this, I checked, the data is not lost, there is just a row counter in the table and a drift of the data I - user
    • It solves the current problem, but at the same time creates several bugs. Therefore, they do not look at the fact that the answer is correct for you; it is not true for others, and that site is a collective base of answers. - Mikhail Vaysman
