Zdravim,
poradi nekdo s konstrukci SQL dotazu (mysql), ktery projede celou tabulku a
smaze veskere radky, v kterych je v urcitem sloupci duplicitni hodnota?
To znamena, ze od kazdeho duplicitniho radku necha v databazi pouze jednu
radku (zaznam). Duplicita se vyhodnocuje v zavislosti shody hodnoty v
sloupci nazvanem 'uniqid'. 

Diky moc
Yd.
