Question

我有一个PowerShell脚本，使用sqlplus命令连接到Oracle数据库并执行查询。

结果如下：

我需要解析这个结果并采取这一部分：

到目前为止我的尝试：

#Using a .txt file report to test
$test = Get-Content -path "C:\Scripts\PS SQL Queries\Agent Failure\Agent Failure Report27012016.0146.txt" | out-string
$start = $test | select-string -pattern "NAME"

这从“NAME”开始给我一个结果，我现在正在寻找一个命令来获得我的选择字符串的反转。具体来说，获取String直到“选择15行”。

Answer 1

你需要一个正则表达式＆＃34; multiline＆＃34; og＆＃34;单线＆＃34;修饰符，因此正则表达式将在换行符中存活并让你使用＆＃34; start-anchor＆＃34;确定在哪里停下来。试试这个：

#Using a .txt file report to test
$test = Get-Content -Path "C:\Scripts\PS SQL Queries\Agent Failure\Agent Failure Report27012016.0146.txt" | Out-String
$start = if($test -match '(?ms)(^NAME.*?)^\s+^\d') { $Matches[1].Trim() }

Answer 2

与大多数正则表达式类似Frode F.'s answer。仍然使用带有-AllMatches的Select-String，因为我们返回了多个匹配项。保留问题中的前几行我会针对$test运行此行。

看起来你想要＆＃34;姓名＆＃34;直到下一组双新线。这就是回归。

($test | Select-String -Pattern "(?s)Name.*?\r\n\r\n" -AllMatches).Matches.Value

根据您的需要，您可以通过一些后期处理获得更具体的信息。请记住，此查询返回了2个多行字符串。

Answer 3

一个肮脏（但简单）的解决方案是使用tee-object将信息输出到屏幕和文件，然后导入文件并解析。

我从未尝试过从powershell通过sqlplus运行oracle命令，我只是直接使用oracle.dataccess.dll和查询/更新。您是否尝试将整个命令设置为变量？

就像$ var =你正在运行的命令一样

查看该数据是否会填充变量，然后您可以非常轻松地解析它。不确定你是否尝试过这个。

如何解析sqlplus查询中的详细信息？
