如何獲得數據庫

的結構細節，我需要所有的用戶定義的數據庫的結構細節如下格式： -如何獲得數據庫

名類型的詳細信息

在哪些細節包括 - 如果它是一個表比列A（式，大小），ColumnB（類型，大小）....，ConstraintA，ConstarintB ...，IndexeA（索引列），IndexB（索引列）.....

如果它是一個函數或過程，該功能或程序。

下面是我所創建的查詢，但它走大約8分鐘的10個數據庫： -

如果你婉獲得TABEL的結構，然後使用類似

SELECT * 
FROM INFORMATION_SCHEMA.COLUMNS 
WHERE table_name = 'tablename'
