この照合の競合の原因となっているクエリの一部を見つけることができませんでした。マスターデータベースの照合はArabic_CI_AI;です。このクエリの結果だけを再現して、エラーの原因を正確に特定することはできませんでした。
どうすればこの問題を解決できますか？

Answer 1

問題はおそらくこの行です：

join msdb.dbo.MSdistpublishers msd on msd.name = ss.srvname

これは文字列の比較であり、どちらの側もリテラルでも変数でもないため、テーブル/ビューの列の照合順序になります。次のクエリを実行すると確認できます。

SELECT ss.srvname
FROM master.dbo.sysservers ss
INNER JOIN msdb.dbo.MSdistpublishers msd
        ON msd.name = ss.srvname;

msdb.dbo.MSdistpublishersのname列にはArabic_CI_ASの照合順序があると思います。

ALTER TABLE ... ALTER COLUMNを使用してその列の照合順序をArabic_CI_AIに変更することは可能ですが、それによって他の問題が発生するかどうかはわかりません。明らかにテストが必要です。

もう1つの選択肢は、システムストアドプロシージャsp_MSrepl_enumpublicationsを更新して、その行を次のように変更することです。

join msdb.dbo.MSdistpublishers msd on msd.name = ss.srvname COLLATE Arabic_CI_AI

追伸この特定の状況は、サーバーレベルの既定の照合順序が異なるサーバーからmsdbを復元した状況と非常に似ています。これは、masterとmsdbの間に照合競合が発生したことを意味します。その質問は次のとおりです。

照合の競合... dbo.sysdac_instancesを使用できませんでした
