SQL 跟踪问题？ 在 SQL 跟踪中，如何判断SQL语句执行是不是错误。

Posted 2023-05-04

SQL Server Profiler工具是来捕获当前执行的SQL语句，并不能反馈执行结果和错误信息在查询分析器窗口执行语句错误自然会提示，要知道错误语句在哪里，可以像楼上那种做法，设置一些Print语句，哪里没打印错误就到哪里。一般我这边写则会定义一个变量用语存放SQL语句，在执行之前加多一句print，这样执行错误就知道语句是那句了如：declare @Sql varchar(2000)set @Sql='select 1'print @Sqlexec(@Sql)set @Sql='update table set abc=124'print @Sqlexec(@Sql) 参考技术A 在你的sql语句后可以print一些标识信息，比如insert into ***(***,***,...) values(***,***,...)print 'OK'这样的话，如果执行失败，OK是不会数出来的

如何在pl sql中跟踪异常终止

【中文标题】如何在pl sql中跟踪异常终止

【英文标题】：How to trace abnormal termination in pl sql

【发布时间】：2014-02-14 09:44:52

【问题描述】：

我有一个处理大约 7000 条记录的 pl sql 文件。根据输入，它会选择插入，更新到不同的表。异常处理程序写在每个查询中。但是我的程序异常终止而没有显示任何错误消息。这种终止每次都发生在不同的代码位置。第一次可能处理1200条记录，下一次处理1400条记录。它与缓存问题有关吗？请提供输入以解决此问题。我正在使用 sql developer 1.5.4。有没有办法调试这样的场景？

添加pl sql文件：

下面是我的 pl sql 文件，它从文件中提到的“marx_resph_bk.txt”读取输入。

而且它永远无法显示我的最终 dbms_output.put_line 用于 Total CNT。

【问题讨论】：

无法回答。您至少应该提供您的脚本和示例输入。投票决定暂停。

请告诉我们存储过程以及如何调用它。

给EXCEPTION一个机会怎么样？如果这不起作用，请返回并再次提出问题。

【参考方案1】：

你的异常处理程序

when others then
dbms_output.put_line(' Selecting tracking Id');
  utl_file.putf(f_errors, 'Select Tracking ID :'||v_tracking_id
    ||':'||sqlerrm);
  rollback;
  return;

包含对文件的错误跟踪写入 - 具有相同信息的 dbms_output.put_line() 怎么样？您可以将其作为假脱机文件输出。似乎您也使用循环 - 结束循环；和 goto 控制方法 - 你可以使用 while() 循环来代替吗？它可能更透明。

我猜你的 RETURN 语句也有问题 - 因为你没有在嵌套块中返回之前关闭文件处理程序你没有关于错误的信息，文件是空的并且你没有到达结尾主块：
