原标题:@@TRANCOUNT and a current connection

Assume I 链接到服务器2008年,通过服务器管理演播室(SSMS )和开放的新窗口W1,点击新金字塔,并在W:

BEGIN TRANSACTION;

如果我执行该声明5次,然后写(在<编码>W1上)。

SELECT @@TRANCOUNT;

然后,退还的价值为5。 但是,如果我打开另一个窗户<代码>W2( 在同一SSMS中,从而在同一链接上)并在W2内部书写

SELECT @@TRANCOUNT; 

然后,退还的价值为0。

@ 现有联系的现役交易数目可变。

W1和W2窗口均在同一链接上开放,因此(根据上述引文)在和<编码>W2 可变@TRANCOUNT具有相同价值?

最佳回答

SSMS的每个查询窗口是separate链接,可单独进行间谍活动。 盘点窗户中的括号是目前窗户的连接号码。

如果你愿意的话,每户都有一个窗口,公开交易,你就应当能够看到其中每一个窗口的显示结果。 利用窗户的间谍号码,你能够发现每行的输血。 你们还可以找到详细信息,了解你在每一盘点窗口底层的地位酒吧以及每个开关窗口的财产窗上的联系。
