例如，我正在寻找这样的命令，它只更新以名称SELECT t2.id, GROUP_CONCAT(t2.r ORDER BY t2.lvl DESC)
FROM (
SELECT id, r, lvl
FROM (
SELECT
t0.r_init AS id,
@r := IF(t0.reset_r = 1, t0.r_init,
(select parent_id from menu where id = @r)) AS r,
@l := IF(t0.reset_r = 1, 1, @l + 1) AS lvl
FROM
(SELECT m0.id as counter, m1.id AS r_init,
((SELECT min(id) FROM menu) = m0.id) AS reset_r
FROM menu m0, menu m1
WHERE m1.id IN (25, 31, 23)
ORDER BY r_init, counter
) t0
ORDER BY t0.r_init, t0.counter
) t1
WHERE r <> 0
) t2
GROUP BY t2.id;
开头的包：
PackagePrefix我尝试了this blog的评论部分中提供的脚本，但它引发了以下错误：
Update-Package "PackagePrefix.*"
Get-Package | Where Id -like "Contoso.*" | Sort-Object -Property Id -Unique | foreach { Update-Package $_.Id }
答案 0 :(得分：0)
在摆弄一下之后，我想我正在使用一个非常旧版本的Powershell（v2.0）并基于the documentation以下脚本现在正常工作。我将Where替换为Where-Object：
Get-Package | Where-Object {$_.Id -like "Contoso.*"} | Sort-Object -Property Id -Unique | foreach { Update-Package $_.Id }
