Das geht so nicht! Guck dir mal an, wie Group Functions arbeiten.
Wenn, dann geht das so:
SQL-Code:
select 's2b_history' as Tabelle, count(*) as Anzahl from s2b_history
union
select 's2b_pic' as Tabelle, count(*) as Anzahl from s2b_pic
union
select 's2b_links' as Tabelle, count(*) as Anzahl from s2b_links
