------解决方案--------------------select sum(a) 
 from (select count(*)as num from a 
 union all  
 select count(*)as num from b 
 union all  
 select count(*)as num from c 
 ..........)ta 
 select (select count(*)as num from a)+(select count(*)as num from b)
------解决方案--------------------select rowcnt from sysindexes where indid <2 and id=object_id( 'a ') union all 
 select rowcnt from sysindexes where indid <2 and id=object_id( 'b ') union all 
 select rowcnt from sysindexes where indid <2 and id=object_id( 'c ')
