За да стигна направо до „кой е блокиран/блокиращ“, комбинирах/съкратих sp_who и sp_lock в една заявка, която дава хубав преглед на това кой какъв обект има заключен до какво ниво.

Копирано от:sp_WhoLock – съхранена процедура в T-SQL, комбинираща sp_who и sp_lock...
NB колоната [Xclusive lock for command] може да бъде подвеждаща - показва текущата команда за този spid; но X заключването може да бъде задействано от по-ранна команда в транзакцията.
