只有主键表

Question

我想找到只有我指定列的主键的表。我正在尝试的如下：

SELECT 
    OBJECT_NAME(ic.OBJECT_ID) AS TableName, 
    1 AS InsertPrimaryGuidOnly, 
    0 AS InsertCustomerOnly, 
    0 AS InsertApplicationOnly, 
    0 AS InsertNoKeyOnly 
FROM 
    sys.indexes AS i 
INNER JOIN 
    sys.index_columns AS ic ON i.OBJECT_ID = ic.OBJECT_ID 
          AND i.index_id = ic.index_id 
WHERE 
    i.is_primary_key = 1 
    AND COL_NAME(ic.OBJECT_ID, ic.column_id) = 'CREDITCHECKGUID'  
    AND OBJECT_NAME(ic.OBJECT_ID) NOT IN ('Customer', 'Application') 

我正在获取表列表，但它也列出了具有作为主键和外键列的下表。我想要的只是主键表。如果主服务器也是外键，我不想列出该表。请帮忙。

把这个where子句放到你的查询中;

AND ic.OBJECT_ID NOT IN (select parent_object_id from sys.foreign_keys fk) 

完整查询;

SELECT 
    ic.OBJECT_ID, 
    OBJECT_NAME(ic.OBJECT_ID) AS TableName, 
    1 AS InsertPrimaryGuidOnly, 
    0 AS InsertCustomerOnly, 
    0 AS InsertApplicationOnly, 
    0 AS InsertNoKeyOnly 
FROM 
    sys.indexes AS i 
INNER JOIN 
    sys.index_columns AS ic ON i.OBJECT_ID = ic.OBJECT_ID 
          AND i.index_id = ic.index_id 
WHERE 
    i.is_primary_key = 1 
    AND COL_NAME(ic.OBJECT_ID, ic.column_id) = 'CREDITCHECKGUID' 
    AND OBJECT_NAME(ic.OBJECT_ID) NOT IN ('Customer', 'Application') 
    AND ic.OBJECT_ID NOT IN (select parent_object_id from sys.foreign_keys fk)
