使用COLUMNPROPERTY。對於UR參考

一） COLUMNPROPERTY (Transact-SQL)

B） Identity Columns

COLUMNPROPERTY函數在SQL CE Compact 3.5中不可用。以下是供您參考的鏈接： http://msdn.microsoft.com/en-us/library/ms174077.aspx – rxm0203 2009-11-01 17:05:01

嘗試以下查詢：

;WITH PK_INFO AS (SELECT CON.TABLE_CATALOG, CON.TABLE_SCHEMA, CON.CONSTRAINT_NAME, USO.COLUMN_NAME 
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS CON 
    JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE USO ON CON.CONSTRAINT_NAME = USO.CONSTRAINT_NAME 
     AND CON.TABLE_CATALOG = USO.TABLE_CATALOG AND CON.TABLE_SCHEMA = USO.TABLE_SCHEMA 
WHERE CON.TABLE_NAME = 'YOUR_TABLE' 
    AND CON.CONSTRAINT_TYPE = 'PRIMARY KEY' 
    ) SELECT DISTINCT CASE WHEN (PK.COLUMN_NAME IS NULL) THEN 0 ELSE 1 END AS COLUMN_IS_PRIMARYKEY, * 
FROM INFORMATION_SCHEMA.COLUMNS COL 
LEFT JOIN PK_INFO PK on COL.COLUMN_NAME = PK.COLUMN_NAME WHERE COL.TABLE_NAME = 'YOUR_TABLE' ORDER BY COL.ORDINAL_POSITION ASC
