清单11被视为一个庞大的条件语句，它基于请求url中的o参数的值执行一个特定的分支。
Listing 11 is best thought of as a giant conditional statement, which executes a particular branch based on the value of the o parameter in the request url.
如果某条语句发出一个存在处理程序的条件，那么SQLSTATE和SQLCODE变量的值就可以在开始执行处理程序时获得。
If a statement raises a condition for which a handler exists, the values of the SQLSTATE and SQLCODE variables are available at the beginning of the handler execution.
如果条件的求值结果为TRUE，那么就将执行语句列表，在循环的顶部恢复控制。
If the condition evaluates to TRUE, the statement list is executed, then control resumes at the top of the loop.
GO TO标签语句可以无条件地退出循环，并将控制权转移到跟在指定的语句标签之后的可执行语句或语句块。
The GOTO label statement can unconditionally exit from a loop and transfer control to the executable statement or statement block that follows the specified statement label.
while语句定义了一个语句集合，如果在WHILE循环开始时某个条件的求值结果为false，那么就将执行这个语句集合。
The WHILE statement defines a set of statements to be executed until a condition that is evaluated at the beginning of the WHILE loop is false.
REPEAT语句定义了一个语句集合，如果在 REPEAT 循环结束时某个条件的求值结果为true，那么就将执行这个语句集合。
The REPEAT statement defines a set of statements to be executed until a condition that is evaluated at the end of the REPEAT loop is true.
bash中的while循环可以重复执行语句一定的次数，或者一直执行到满足某一条件为止。
A while loop within bash allows you to execute a statement a given number of times, or until a certain condition is met.
在某些条件下，会在merge语句执行过程中创建内部临时表，如清单7所示。
Under certain conditions, internal temporary tables are created during the execution of the merge statement, as shown in Listing 7.
如果没有条件为真，则将执行“else ”操作，如果有一个条件为真，则继续执行整个“if,elif, else ”语句之后的行。
If none of the conditions are true, it will execute the "else" action, if one is present, and then continue executing lines following the entire "if, elif, else" statement.
bash中的case语句可以用来测试多个条件或值并相应地执行操作。
A case statement within bash lets you test for more than one condition or value and act accordingly.
范围锁处于与事务中执行的每个语句的搜索条件相匹配的键值范围之内。
Range locks are placed in the range of key values that match the search conditions of each statement executed in a transaction.
另一种常见的算法结构是当条件为“真”时，循环执行一条语句或者语句序列。
Another common algorithmic structure involves that the need to continue executing a statement or sequence of statements as long as some condition remains true.
断言代码在调试阶段执行，如果发现某个执行代码语句条件没有得到满足，通常会给出相应信息并停止执行。
The assertion code is executed during debugging, and if one of the conditions is found not to hold, execution statement condit assert usually stops with a message.
你可以说如果条件成立，执行下面的代码段，或板块中的拼图，否则跳过去执行这下面的语句。
You can say if this is true, then go and do the following pieces of code or puzzle pieces that are inside this part of the block, else go ahead and do these that are down here.
汇编语言依序执行算术指令，而跳转指令可以通过改变程序计数器的值来执行条件语句和循环语句。
Assembly language instruction sequence perform arithmetic, and jump instruction by changing the program counter value to execute the conditional statement and circular statement.
必要条件是，在包含程序执行后，解释程序的语句在包含程序的开始。
The requirement is that, after execution of the Include program, a statement that introduces a program is at the beginning of the including program.
必要条件是，在包含程序执行后，解释程序的语句在包含程序的开始。
The requirement is that, after execution of the Include program, a statement that introduces a program is at the beginning of the including program.
