Question

有什么方法可以获取所有表，条件是如果表不为空（如果存在某些记录）。

我可以使用：

获取表列表

USE 'DatabaseName'
SELECT * FROM INFORMATION_SCHEMA.TABLES WHERE table_Schema = 'dbo'
ORDER BY table_NAME.

但是，我想要类似

SELECT * FROM INFORMATION_SCHEMA.TABLES WHERE table_Schema = 'dbo'
    AND "**table has some records present**" ORDER BY table_NAME

Answer 1

尝试：

SELECT
        OBJECT_NAME(T.OBJECT_ID) AS TABLE_NAME,
        SUM(P.ROWS)  AS TOTAL_ROWS
FROM
        sys.tables T
INNER JOIN 
        sys.partitions P 
        ON T.OBJECT_ID = P.OBJECT_ID
WHERE 
        P.INDEX_ID IN (0,1)
GROUP BY 
        T.OBJECT_ID
HAVING 
        SUM(P.ROWS) > 0

Answer 2

运行此

select 'select count(*) [entries],'''+ TABLE_NAME + ''' from '+ quotename(TABLE_SCHEMA) + '.' + quotename(TABLE_NAME) + ' union' from INFORMATION_SCHEMA.TABLES

要获取每个表的列表以及该表中条目的数量，则可以将其放入临时表中，并查找条目> 1的任何内容。

请记住在最后删除联合。

Answer 3

select * from
   ( 
    SELECT sc.name +'.'+ ta.name TableName
    ,SUM(pa.rows) RowCnt
    FROM sys.tables ta
    INNER JOIN sys.partitions pa
    ON pa.OBJECT_ID = ta.OBJECT_ID
    INNER JOIN sys.schemas sc
    ON ta.schema_id = sc.schema_id
    WHERE ta.is_ms_shipped = 0 AND pa.index_id IN (1,0)
    GROUP BY sc.name,ta.name
    ORDER BY SUM(pa.rows) DESC
) as T where RowCnt>0
