如何獲取具有標識列的所有表的列表

Question

我想了解如何從MS SQL數據庫中獲取具有標識列的所有表的列表。

Answer 1

SELECT 
    [schema] = s.name, 
    [table] = t.name 
FROM sys.schemas AS s 
INNER JOIN sys.tables AS t 
    ON s.[schema_id] = t.[schema_id] 
WHERE EXISTS 
(
    SELECT 1 FROM sys.identity_columns 
    WHERE [object_id] = t.[object_id] 
); 

Answer 2

 select COLUMN_NAME, TABLE_NAME 
     from INFORMATION_SCHEMA.COLUMNS 
     where TABLE_SCHEMA = 'dbo' 
     and COLUMNPROPERTY(object_id(TABLE_NAME), COLUMN_NAME, 'IsIdentity') = 1 
     order by TABLE_NAME 

Answer 3

我喜歡這種方法，因爲它使用WHERE EXISTS或COLUMNPROPERTY呼叫的，而不是加入的。需要注意的是該集團是唯一必要的，如果你一）有表有一個以上的IDENTITY列和b）不想重複結果：

SELECT 
    SchemaName = s.name, 
    TableName = t.name 
FROM 
    sys.schemas AS s 
    INNER JOIN sys.tables AS t ON s.schema_id = t.schema_id 
    INNER JOIN sys.columns AS c ON t.object_id = c.object_id 
    INNER JOIN sys.identity_columns AS ic on c.object_id = ic.object_id AND c.column_id = ic.column_id 
GROUP BY 
    s.name, 
    t.name 
ORDER BY 
    s.name, 
    t.name; 

Answer 4

選擇OBJECT_NAME（OBJECT_ID）RROM sys.identity_columns 其中is_identity = 1;

Answer 5

下面的腳本就可以了：

SELECT a.name as TableName, 
    CASE WHEN b.name IS NULL 
    THEN 'No Identity Column' 
    ELSE b.name 
    END as IdentityColumnName 
FROM sys.tables a 
    LEFT JOIN sys.identity_columns b on a.object_id = b.object_id
