1.try catch 个人理解 try catch是sql用于出错异常处理的语句块,当我们在写sql语句的时候(通常写比较复杂的存储过程时),合理使用try catch 可以将sql代码运行时的错误信息捕获,从而可以让我们 不需要处处判断便可以更加简单地处理我们所遇到的问题。 例如: 我们的过程脚本里面经常要进行除法计算 如这段代码 declare ...
A. 在 CATCH 块中使用 ERROR_MESSAGE 下面的代码示例显示一个生成被零除错误的 SELECT 语句。将返回错误消息。 复制 USE AdventureWorks; GO BEGIN TRY -- Generate a divide-by-zero error. SELECT 1/0; END TRY BEGIN CATCH SELECT ERROR_MESSAGE() AS ErrorMessage; END CATCH; GO ...
END TRY BEGIN CATCH SELECT ERROR_NUMBER() AS ErrorNumber, ERROR_MESSAGE() AS ErrorMessage END CATCH GO 这个存储过程尝试插入一个新的员工。如果插入操作失败,它将返回错误号和错误消息。 以上就是MSSQL存储过程的功能和用法。通过学习这些,你应该能够开始使用存储过程进行数据库操作。在实践中,你将发现存储过...

Above, in the TRY block we issue a RAISERRROR with a set message. In the CATCH block, the RAISERROR sends the actual error that was encountered. SQL SERVER THROW The THROW statement in SQL Server is used to raise an exception.
我们还可以在Begin catch中使用raiserror。示例如下: 代码语言:javascript 复制 begintryraiserror('这是一个错误',16,1)//注意,只有severity级别在11~19之间,控制才会跳转到catch块中。endtrybegin catch declare @error_messagevarchar(1000)set @error_message=error_message()raiserror(@error_message,16,1)retu...
