iteration statement

基本解释

The Boolean-expression is evaluated once at the beginning of the loop and again before each further iteration of the statement.
在循环刚开始时，会计算一次“ 布尔表达式”的值。而对于后来每一次额外的循环，都会在开始前重新计算一次。

In the phase of data dependency analysis, we give the algorithms for removing inter-statement and inter-iteration false dependencies.
该改进算法通过引入函数调用和返回引起的控制转移来计算函数间的控制依赖关系。
In this case, 101 network roundtrips are required to perform 100 insert operations?1 roundtrip to prepare the statement and 100 additional roundtrips to execute each iteration.
在这里, 执行了100次INSERT操作, 共有101次网络往返. 其中,1次往返是预储statement, 另外100次往返执行每个迭代.
