您好我在Windows文档中找到了此代码
但我没有得到什么意思
[&]
只是请你能清楚我该怎么办？
它不是c ++标准的真实？
这是代码:
void parallel_matrix_multiply(double** m1, double** m2, double** result, size_t size)
{
parallel_for (size_t(0), size, [&](size_t i)
{
for (size_t j = 0; j < size; j++)
{
double temp = 0;
for (int k = 0; k < size; k++)
{
temp += m1[i][k] * m2[k][j];
}
result[i][j] = temp;
}
});
}
我有这个程序:
create or replace procedure changePermissionsToRead(
datasource in varchar2
)
IS
begin
update
(
select * from
WEB_USERROLE ur ,
WEB_USERDATASOURCE ds
where
ur.username = ds.username
and
ds.datasource = datasource
and
ur.READ_ONLY <> 'Y'
)
r set r.role = replace(r.role, 'FULL', 'READ');
end;
我收到以下错误:
ORA-01779
但如果我拿出更新,我写道:
update
(
select * from
WEB_USERROLE ur ,
WEB_USERDATASOURCE ds
where
ur.username = ds.username
and
ds.datasource = 'PIPPO'
and
ur.READ_ONLY <> 'Y'
)
r set r.role = replace(r.role, 'FULL', 'READ');
然后这很好用.你能告诉我发生了什么吗？

我应该部署的文件只是html文件或js或图像,编译应用程序后出现以下错误: …
我尝试为Supercontainer对象制作一个getter和setter,但它似乎不起作用.
PrometeiaECAProModuleMain.factory('ParameterFactory', [function () {

在一个代码中,一个类启动一个线程调用start方法.
它抛出了一个非法的例外.但是,如果我调用run()它会很好.
你能告诉我为什么吗？
class A{
void methodA(){
T t = new T();
t.start(); // illegal state exception
t.run(); ///ok
}
}
class T extends Thread{
....
....
}
