要使用doQuery方法，需要建立数据库连接并且从try ...catch块内调用方法，如清单4 所示。
With the asyncEcho test, it wraps the asserts in a try/catch, and any errors are passed back to the DOH through the deferred.errback(error) call.

To detect this bug pattern, you'll need to know where the try-catch blocks are, what might be thrown out of the try block, and what is caught in the catch blocks.
要检测此bug模式，则需要知道try -catch块的位置、try块可能抛出的内容以及在catch块中将捕获的内容。
Each CodeException contains the starting and ending bytecode offset for the corresponding try block, so you can easily determine which CodeException objects correspond to a try-catch block.
每个CodeException都包含相应try块的起始和终止的字节码偏移量，这样您可以方便地确定哪一个CodeException对象与try - catch块对应。
While on the subject, it's worth noting that although the examples in this series use try-catch() blocks to trap and handle exceptions, this isn't strictly necessary.
关于这个问题，有一点值得注意：尽管本系列中的示例使用 try-catch() 代码块来捕捉和处理异常，但这并不是必须的。
These contain information about all the try-catch blocks in the method, so you'll have to correlate the throw and catch information to identify the bug pattern.
它们包含关于方法中所有try - catch块的信息，所以您必须将抛出信息和捕获信息关联，以标识bug模式。
The code should ideally be wrapped by try-catch blocks.
最好把代码放在try -catch块中。
When invoking unknown code (which listeners certainly qualify as), it is prudent to execute it in a try-catch block so that ill-behaved listeners do not do more damage than necessary.
在调用未知代码(侦听器就是这样的代码)时，谨慎的方式是在try - catch块中执行它，这样，行为有误的侦听器不会造成更多不必要的破坏。
If the content isn't supported, the code throws an exception, which is caught by the try-catch block.
如果内容不受支持，那么代码抛出一个异常，此异常由try - catch块捕捉到。
Because the category property can either be multivalued or single-valued, you check for it with a try-catch statement.
因为分类属性可以是多值的也可以是单值的，所以要用try - catch语句检查它。
Use TRY..CATCH construct or check the @@ERROR variable after executing a data manipulation statement (like INSERT/UPDATE/DELETE).
在执行数据操作语句（像INSERT/UPDATE/DELETE)之后，使用TRY..CATCH结构或者检查该@@ERROR变量
However, you'll still need to use the old try-catch style if you want to test the exception's detail message or other properties.
但是如果您想要测试异常的详细消息或其他属性，则仍然需要使用旧式的try - catch样式。
From the SOAP client perspective, it's a good idea to wrap the SOAP call inside a try-catch block, so that SOAP faults like the one above can be caught and handled gracefully.
对于SOAP客户端来说，将这个SOAP调用封装在一个try - catch代码块中是很好的做法，这样类似于上面的SOAP错误就会被顺利地捕捉和处理。
If the stored procedure contains a TRY... CATCH construct, the error transfers control to the CATCH block in the stored procedure.
如果存储过程包含TRY…CATCH构造，则错误会将控制传输给存储过程中的CATCH块。
If the stored procedure contains a TRY... CATCH construct, the error transfers control to the CATCH block in the stored procedure.
如果存储过程包含TRY…CATCH构造，则错误会将控制传输给存储过程中的CATCH块。
