oracle想批量修改某一列的值，修改成成bh0001，bh0002以次往下，怎么实现，感谢！

Answer 1

可以用游标解决：
declare @dbname nvarchar(20)
declare curdb cursor for
select name from master..sysdatabases where name like 'depart%' --找出所有要更新的数据库

open curdb
fetch next from curdb into @dbname
while @@fetch_status=0
begin
exec ('update '+ @dbname +'..SPML SET PM=''相应名称'' WHERE BH=''相应名称'' ' )
fetch next from curdb into @dbname
end
close curdb
deallocate curdb
