我在EXEC SQL的两个段之间有一个带有SQL查询的大文本文件--- END-EXEC.

I have a big text file with SQL query in between blocks of EXEC SQL --- END-EXEC.

我需要介于EXEC SQL --- END-EXEC之间的所有内容.关键字.示例输入如下.

I need everything in-between EXEC SQL --- END-EXEC. keywords. Sample Input is below.

这就是我要尝试的方法.如果有一块EXEC SQL --- END-EXEC，我就能得到内容.但是，如果有多个EXEC SQL --- END-EXEC.块，我失败了.

This is how I'm trying to do. I'm able to get the contents if there is one block of EXEC SQL --- END-EXEC. However, If there are multiple EXEC SQL --- END-EXEC. blocks, I am failing.

a)以字符串形式读取文件.

a) Read the file as a string.

我要使用

$content = [io.file]::ReadAllText("$pathtofile") $content = $content -replace "\s*`n", " " (p.s. I'm using V2.0 so cannot use -raw option)

b)然后我执行此操作以匹配EXEC关键字之间的所有内容.

b) Then I doing this to match everything in between EXEC keyword.

$result = $content -match "EXEC(.*)EXEC" $matches[0] > D:\result.txt

输入:

* ABCD ABCD ABCD BLAH BLAH BLAH - This is some text preceding EXEC SQL **EXEC SQL** DECLARE TMPMOTT-CUR CURSOR FOR SELECT KONTYP ,BFDAT ,MARK ,MOTT ,AVS ,BEL ,OKLBE FROM ABCBEFGH ORDER BY MOTT **END-EXEC**. * ABCD ABCD ABCD BLAH BLAH BLAH - This is some text after END-EXEC.

推荐答案

$script = Get-Content D:\temp\script.sql $in = $false $script | %{ if ($_.Contains("EXEC SQL")) { $in = $true } elseif ($_.Contains("END-EXEC")) { $in = $false; } elseif ($in) { Write-Host $_ } # Or Out-File ... }
