テーブル名が日本語の時の列定義

[こっぺぱん]

テーブル名の物理名が日本語のテーブルを読み込んだ際カラムのデータ型がstringなどになり、テーブル設計の列定義が空になります。テーブル名がローマ字のみの場合は列定義が表示されていることから日本語であることが問題なのかと思っております。
こちら解決策などはありますでしょうか。

こっぺぱんさんこんにちは。
　
こちらで、Microsoft SQL Server 2019 を使用して試してみたのですが、日本語でもカラム情報は正しく表示されるようでした。

以下のSQLは正しく表示できますでしょうか？

SELECT c.name AS COLUMN_NAME , tp.name AS DATA_TYPE , c.max_length AS LENGTH , c.precision AS [PRECISION] , c.scale AS [SCALE] , c.is_nullable AS IS_NULLABLE , dc.definition AS COLUMN_DEFAULT , cc.definition AS COMPUTE_COLUMN , c.is_identity , ep.value as COLUMN_COMMENT FROM sys.all_columns AS c INNER JOIN sys.all_objects AS t ON t.object_id = c.object_id AND t.type IN ('IT', 'U', 'U', 'V', 'SN') INNER JOIN sys.schemas ts ON ts.schema_id = t.schema_id INNER JOIN sys.types AS tp ON c.user_type_id = tp.user_type_id LEFT JOIN sys.default_constraints AS dc ON dc.object_id = c.default_object_id LEFT JOIN sys.computed_columns cc ON cc.object_id = t.object_id AND cc.column_id = c.column_id LEFT JOIN sys.extended_properties ep ON ep.major_id = t.object_id AND ep.minor_id = c.column_id AND ep.class = 1 AND ep.name = 'MS_Description' AND ep.minor_id <> 0 WHERE ts.name = 'スキーマ名' AND t.name ='テーブル名' ORDER BY c.column_id

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

SELECT     c.name AS COLUMN_NAME     , tp.name AS DATA_TYPE     , c.max_length AS LENGTH     , c.precision AS [PRECISION]     , c.scale AS [SCALE]     , c.is_nullable AS IS_NULLABLE     , dc.definition AS COLUMN_DEFAULT     , cc.definition AS COMPUTE_COLUMN     , c.is_identity     , ep.value as COLUMN_COMMENT FROM     sys.all_columns AS c     INNER JOIN sys.all_objects AS t         ON t.object_id = c.object_id         AND t.type IN ('IT', 'U', 'U', 'V', 'SN')       INNER JOIN sys.schemas ts         ON ts.schema_id = t.schema_id     INNER JOIN sys.types AS tp         ON c.user_type_id = tp.user_type_id     LEFT JOIN sys.default_constraints AS dc         ON dc.object_id = c.default_object_id     LEFT JOIN sys.computed_columns cc         ON cc.object_id = t.object_id         AND cc.column_id = c.column_id     LEFT JOIN sys.extended_properties ep         ON ep.major_id = t.object_id         AND ep.minor_id = c.column_id         AND ep.class = 1         AND ep.name = 'MS_Description'         AND ep.minor_id <> 0 WHERE     ts.name = 'スキーマ名'     AND t.name ='テーブル名' ORDER BY     c.column_id

※スキーマ名・テーブル名は適宜修正してください。
