我正在寻找一个SQL脚本,可用于确定是否有任何数据(即行计数)在给定数据库的任何表。

这样做的目的是在存在任何行(在任何数据库中)的情况下重新具体化数据库。

这里所说的数据库是Microsoft SQL SERVER。

谁能建议一个示例脚本?

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

SQL Server 2005或更高版本提供了一个相当不错的报告,显示表大小-包括行数等。这是在标准报告-它是光盘使用表。

在编程上,有一个很好的解决方案: http://www.sqlservercentral.com/articles/T-SQL/67624/

在Azure上工作,不需要存储过程。

SELECT t.name       AS table_name
       ,s.row_count AS row_count
FROM   sys.tables t
JOIN   sys.dm_db_partition_stats s
  ON t.OBJECT_ID = s.OBJECT_ID
 AND t.type_desc = 'USER_TABLE'
 AND t.name NOT LIKE '%dss%' --Exclude tables created by SQL Data Sync for Azure.
 AND s.index_id IN (0, 1)
ORDER  BY table_name;

信贷。

从information_schema中选择所有行。表视图,并为从该视图返回的每个条目发出count(*)语句。

declare c_tables cursor fast_forward for
select table_name from information_schema.tables

open c_tables
declare @tablename varchar(255)
declare @stmt nvarchar(2000)
declare @rowcount int
fetch next from c_tables into @tablename

while @@fetch_status = 0
begin

    select @stmt = 'select @rowcount = count(*) from ' + @tablename

    exec sp_executesql @stmt, N'@rowcount int output', @rowcount=@rowcount OUTPUT

    print N'table: ' + @tablename + ' has ' + convert(nvarchar(1000),@rowcount) + ' rows'

    fetch next from c_tables into @tablename

end

close c_tables
deallocate c_tables

短而甜

sp_MSForEachTable 'DECLARE @t AS VARCHAR(MAX); 
SELECT @t = CAST(COUNT(1) as VARCHAR(MAX)) 
+ CHAR(9) + CHAR(9) + ''?'' FROM ? ; PRINT @t'

输出:

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
