Question

我需要以下格式的所有用户定义数据库的结构细节： -

名称类型详情

其中的详细信息包括 - 如果它是一个表而不是列A（类型，大小），ColumnB（类型，大小）....，ConstraintA，ConstarintB ...，IndexeA（索引列），IndexB（IndexedColumns） .....

如果它是该功能或程序的主体的功能或程序。

以下是我创建的查询，但10个数据库大约需要8分钟： -

如果您想获得表格的结构，请使用

之类的东西

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