如何获取表的架构名称

Question

我正在使用 SQL Server 2008 并且有以下查询：

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

如何检索表的架构名称？

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

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 

如果要根据object_id 知道架构名称，请使用OBJECT_SCHEMA_NAME()，如果您想根据schema_id 获取架构名称，请使用SCHEMA_NAME()。
