功能没有＆＃34;短路＆＃34;。 Does the iif function compute both paths in SSRS or is it short-circuited?
那么，IIF功能不短路吗？换句话说，假设我们有Switch：
Switch当然是一个人为的例子。
是否会导致错误，因为它会评估5/0？
答案 0 :(得分：1)
Switch 不会短路。它显示与iif评估所有条件相同的行为。
但表达式Switch(True, 5, False, 5/0)不会显示#error。
它会评价很好。它将显示5.由于5/0将在SSRS中评估为infinity而不是#error。
更好的测试将是
=SWITCH(TRUE,5,FALSE,5/"")
使用上述表达式时，SSRS会将其评估为#error而不是5。
