| 1. | Iteration statements cause embedded statements to be executed a number of times , subject to the loop - termination criteria
迭代语句导致嵌入语句根据循环终止条件多次执行。 |
| 2. | If your system executes strings multiple times , it is a major speedup to precompile to bytecode in this fashion
如果你的系统需要多次执行字符串，以这种方式预编译成字节码可以大大提高速度。 |
| 3. | Parameterized queries yield better performance by compiling the query only once and executing the compiled plan multiple times
通过只编译一次查询然后多次执行编译好的计划，参数化查询可以提供更好的性能。 |
| 4. | Statement objects , especially if you have to execute the same statement multiple times and the only difference is a different parameter . the
对象更高，尤其是如果您必须多次执行同一条语句而差别仅在于参数不同时更是如此。 |
| 5. | These three statements let you change the flow of a program by selecting which statements are executed or by executing a set of statements multiple times
这三种语句通过选择执行哪些语句，或者通过多次执行一组语句，让您可以改变程序流。 |
| 6. | Very often when you write code , you want the same block of code to run a number of times . you can use looping statements in your code to perform this
在书写代码时，你经常会发现，某个代码快要被多次执行。如果出现了这种情况，你就可以通过循环语句来实现它。 |
| 7. | A prepared statement allows you to take a commonly used sql statement and pre - compile it , thereby dramatically improving performance if the statement is executed multiple times
预备语句允许您用一条常用的sql语句然后预编译它，从而在这条语句被多次执行的情况下大幅度地提升性能。 |
| 8. | Can be used instead of stored procedures when executing a transact - sql statement several times , when the only variation is in the parameter values supplied to the transact - sql statement
当提供给transact - sql语句的参数值只有一个变量时，如果要多次执行transact - sql语句，则可以使用 |
| 9. | Also , because profiling relies on monitoring the number of executions of different parts of your application it can , on occasion , give misleading advice about where a problem lies and the best approach for resolving it
而且，由于profiling依赖于监视应用程序不同部分的多次执行情况，所以有时候，对问题出在哪儿以及问题的解决方法，它会给出一些错误的建议。 |
