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.
在循環剛開始時，會計算一次“ 佈爾表達式”的值。而對於後來每一次額外的循環，都會在開始前重新計算一次。

In the phase of data dependency analysis, we give the algorithms for removing inter-statement and inter-iteration false dependencies.
該改進算法通過引入函數調用和返廻引起的控制轉移來計算函數間的控制依賴關系。
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.
在這裡, 執行了100次INSERT操作, 共有101次網絡往返. 其中,1次往返是預儲statement, 另外100次往返執行每個疊代.
