Question

我知道我可以使用

获取表格列表

SELECT TABLE_NAME FROM information_schema.tables 
WHERE NOT TABLE_NAME='sysdiagrams' 
  AND TABLE_SCHEMA = 'dbo' 
  AND TABLE_TYPE= 'BASE TABLE'

但我不知道如何修改它以获得具有表的当前行数的第二列。我虽然喜欢这样的东西：

DECLARE @tbl VARCHAR(200)
(SELECT @tbl = TABLE_NAME, TABLE_NAME,
(SELECT COUNT(ID) AS Cnt FROM @tbl)
FROM information_schema.tables 
WHERE NOT TABLE_NAME='sysdiagrams' 
  AND TABLE_SCHEMA = 'dbo' 
  AND TABLE_TYPE= 'BASE TABLE')

我知道上面的内容不是有效的T-SQL，但我认为它已经完成了喜欢所做的事情。这适用于SQL Server 2000.如果可能的话，我宁愿不使用存储过程。

Answer 1

快速而肮脏的方式（包括未提交的更改以及可能在堆上的转发指针）

select o.name, rows 
from sysindexes i join sysobjects o on o.id=i.id
where indid < 2 and type='U'

Answer 2

exec sp_MSforeachtable 'select count(*) as nr_of_rows, ''?'' as table_name from ?'

Answer 3

你可以全力以赴。使用sysIndexes获取行计数的问题在于它们并不总是最新的。但是，有一种方法可以使它们都是最新的。以下代码将为您提供每个表的行数以及更多的行数。

/**********************************************************************************************************************
 Purpose:
 Returns a single result set similar to sp_Space used for all user tables at once.

 Notes:
 1. May be used as a view, stored procedure, or table-valued function.
 2. Must comment out 1 "Schema" in the SELECT list below prior to use.  See the adjacent comments for more info.
