Sql server 在SQL Server 2005数据库中记录存储过程错误
我正在为我的TSQL存储过程使用下面所示的通用构造。这对于将错误信息返回到调用应用程序代码非常有效。但是，我也希望将错误记录在数据库本身中。如何在SQLServer2005中实现这一点Sql server 在SQL Server 2005数据库中记录存储过程错误,sql-server,tsql,Sql Server,Tsql,我正在为我的TSQL存储过程使用下面所示的通用构造。这对于将错误信息返回到调用应用程序代码非常有效。但是，我也希望将错误记录在数据库本身中。如何在SQLServer2005中实现这一点 BEGIN TRY TSQL...

创建一个包含列（MessageText、Severity、State、DateTimeOccessed）的错误表，并将信息插入其中。创建一个包含列（MessageText、Severity、State、DateTimeOccessed）的错误表然后
将信息插入其中。创建一个错误日志表，并将其写入CATCH块中
但这并不是那么容易
但是，您需要先测试“@@TRANCOUNT=0”，因为它将在以后回滚，例如您是否使用TRY/CATCH嵌套存储过程或是否有客户端事务。如果使用SET XACT\u ABORT ON
这意味着如果有嵌套，可能会有多条错误消息，因此我还要记录error\u PROCEDURE（）
和OBJECT\u NAME（@@PROCID）

，以区分错误发生的位置和记录的位置 简单的答案是“写入日志表”，但实际上这有点复杂，因为您所做的任何表写入都受当前事务的影响，而catch块受错误处理三态事务的影响。您必须使用来检查当前事务状态。如果是一个注定失败的事务（状态-1），则必须首先回滚，然后记录，否则尝试插入日志表将导致批处理中止
有关使用T-SQL try/catch块并正确处理事务的过程模板的示例，请参见。简单的答案是“写入日志表”，但实际上这有点复杂，因为您所做的任何表写入都受当前事务的约束，而catch块受错误处理三态事务的约束。您必须使用来检查当前事务状态。如果是一个注定失败的事务（状态-1），则必须首先回滚，然后记录，否则尝试插入日志表将导致批处理中止

从长远来看，混合的try-catch逻辑和返回错误代码是行不通的。可以保证，有人会忘记检查过程返回代码，并依靠calee回滚的事务的存在向前推进！可以说，通过使用保存点，单独依赖异常并正确处理XACT_状态的所有3种状态要好得多，从而允许调用方决定在发生错误时是回滚还是继续使用备用路径。许多错误是可以恢复的。谢谢你提供了这样一个完整的例子@Remus Rusanu，我们从不使用保存点，总是回滚，因此调用方几乎没有选项，因为事务计数不匹配，它将自动转到捕获。混合的try-catch逻辑和返回错误代码从长远来看是不起作用的。可以保证，有人会忘记检查过程返回代码，并依靠calee回滚的事务的存在向前推进！可以说，通过使用保存点，单独依赖异常并正确处理XACT_状态的所有3种状态要好得多，从而允许调用方决定在发生错误时是回滚还是继续使用备用路径。许多错误是可以恢复的。谢谢你提供了这样一个完整的例子@Remus Rusanu，我们从不使用保存点，总是回滚，因此调用方几乎没有选项，因为事务计数不匹配，它将自动转到捕获。
