sql - 数据库中所有列的逗号分隔列表(表名 | 列名...)

Question

在 SQL Server 中，我希望看到 Table_Name 以及数据库中与该 Table_Name 关联的所有列。所以输出应该是这样的:

      TABLE_NAME     COLUMN_NAME 

   1. Employee       Employee-id, Lastname, Firstname, Title...........
   2. Orders         Orderid, Order-date, shipped-date, delivery-date.......
   3. Products       Product-id, Product-name, supplier-id, category-id.....
   4. Suppliers      Supplier-id, Company-name, contact-name.......
   5. ............................................................
   6. ...................................................
      (So on....)

是否可以通过WHILE LOOP或其他方式得到上述结果？如果是，您可以发布代码吗？

此外，我尝试使用临时表来解决此问题:

 create table #hello
 (table_name1 Varchar(max))
  insert into #hello(table_name1)
  select table_name from information_schema.columns 
 GO

 create table #hello2
 (table_name2 varchar(max),column_name2 varchar(max))
  insert into #hello2(table_name2 ,column_name2)
  select table_name,column_name from information_schema.columns 
 GO

 select  a.table_name1,b.column_name from #hello a inner join
   information_schema.columns b
 on a.table_name1=b.table_name COLLATE Latin1_general_CI_AS
 order by table_name 
 GO      

我成功地垂直列出了列，但无法获得逗号分隔的列列表。

Answer 1

Select TABLE_SCHEMA, TABLE_NAME
    , Stuff(
        (
        Select ', ' + C.COLUMN_NAME
        From INFORMATION_SCHEMA.COLUMNS As C
        Where C.TABLE_SCHEMA = T.TABLE_SCHEMA
            And C.TABLE_NAME = T.TABLE_NAME
        Order By C.ORDINAL_POSITION
        For Xml Path('')
        ), 1, 2, '') As Columns
From INFORMATION_SCHEMA.TABLES As T

正如评论中提到的，以上内容将包含 View 。如果您想排除 View ，可以执行以下操作:

Select T.TABLE_SCHEMA, T.TABLE_NAME
    , Stuff(
        (
        Select ', ' + C.COLUMN_NAME
        From INFORMATION_SCHEMA.COLUMNS As C
        Where C.TABLE_SCHEMA = T.TABLE_SCHEMA
            And C.TABLE_NAME = T.TABLE_NAME
        Order By C.ORDINAL_POSITION
        For Xml Path('')
        ), 1, 2, '') As Columns
From INFORMATION_SCHEMA.TABLES As T
    Left Join INFORMATION_SCHEMA.VIEWS As V
        On V.TABLE_SCHEMA = T.TABLE_SCHEMA
            And V.TABLE_NAME = T.TABLE_NAME
Where V.TABLE_NAME Is Null
