如何获取表的模式名称

Question

我是使用SQL Server 2008，以下是我的查询语句：

SELECT SO1.name AS Tab, 
       SC1.name AS Col, 
       SO2.name AS RefTab, 
       SC2.name AS RefCol, 
       FO.name AS FKName
FROM dbo.sysforeignkeys FK  
INNER JOIN dbo.syscolumns SC1 ON FK.fkeyid = SC1.id AND FK.fkey = SC1.colid 
INNER JOIN dbo.syscolumns SC2 ON FK.rkeyid = SC2.id AND FK.rkey = SC2.colid 
INNER JOIN dbo.sysobjects SO1 ON FK.fkeyid = SO1.id 
INNER JOIN dbo.sysobjects SO2 ON FK.rkeyid = SO2.id 
INNER JOIN dbo.sysobjects FO ON FK.constid = FO.id

如何获取表格的模式名称？

感谢您的帮助。

Answer 1

使用OBJECT_SCHEMA_NAME

SELECT 
  OBJECT_SCHEMA_NAME(f.parent_object_id) AS TableNameSchema, -- this
  OBJECT_NAME(f.parent_object_id) AS TableName,
  COL_NAME(fc.parent_object_id,fc.parent_column_id) AS ColumnName,
  OBJECT_SCHEMA_NAME(f.referenced_object_id) AS ReferenceTableNameSchema,
  OBJECT_NAME (f.referenced_object_id) AS ReferenceTableName,
  COL_NAME(fc.referenced_object_id,fc.referenced_column_id) AS ReferenceColumnName,
  f.name AS ForeignKey
FROM
  sys.foreign_keys AS f
  INNER JOIN sys.foreign_key_columns AS fc ON f.OBJECT_ID = fc.constraint_object_id
  INNER JOIN sys.objects AS o ON o.OBJECT_ID = fc.referenced_object_id

我使用了这个来获取数据库中所有外键的列表。谢谢！ - Zero3

根据Sql Server 2008：

 SELECT Object_name(f.parent_object_id) 
       AS 
       TableName, 
       Col_name(fc.parent_object_id, fc.parent_column_id) 
       AS ColumnName, 
       Object_name (f.referenced_object_id) 
       AS ReferenceTableName, 
       Col_name(fc.referenced_object_id, fc.referenced_column_id) 
       AS 
       ReferenceColumnName, 
       f.name 
       AS ForeignKey, 
       Quotename(Schema_name(f.schema_id)) + '.' + Quotename( 
       Object_name(f.parent_object_id)) AS 
       schemaname, 
       Quotename(Schema_name(o.schema_id)) + '.' + Quotename( 
       Object_name(f.referenced_object_id)) 
                                        AS ReferenceSchemaName 
FROM   sys.foreign_keys AS f 
       INNER JOIN sys.foreign_key_columns AS fc 
         ON f.OBJECT_ID = fc.constraint_object_id 
       INNER JOIN sys.objects AS o 
         ON o.OBJECT_ID = fc.referenced_object_id 

如果想根据object_id查找模式名称，则使用OBJECT_SCHEMA_NAME()。如果想根据schema_id获取模式名称，则使用SCHEMA_NAME()。

推荐使用 QUOTENAME 替代 '['+...+']'。它可以正确地双引号嵌入在名称中的 ] 字符，而使用 +...+ 的方法会错过这些字符。 - Remus Rusanu

@RemusRusana - 我正在尝试这段代码 create table #t ( nam varchar(100) ) insert into #t(nam)values('abc[]def') select * from #t Where Quotename(nam) like Quotename('abc[]def') drop table #t 但是没有给我任何结果... - Nilish
