在同一查询中获取计数和行数

Question

是否可以在同一查询中获取总表count和rows。像这样的东西

SELECT COUNT(1),*
FROM tbl
GROUP BY ALL

Answer 1

你可以尝试这样的事情：

SELECT
    COUNT(*) OVER (),
    (list of your other columns here)
FROM dbo.YourTableNameHere

OVER()子句将为您提供查询中所有行的计数。

Answer 2

试试这个，

SELECT (select count(*) from table), b.*
  FROM table b;

Answer 3

您可以使用：

1）select column1,coulmn2,COUNT(*) OVER (PARTITION BY 1) as RowCnt from #Table;

2）使用交叉连接方法：

SELECT a.*, b.numRows
      FROM TABLE a
CROSS JOIN (SELECT COUNT(*) AS numRows
              FROM TABLE) b

Answer 4

我也找到了这个，marc_c的答案会比这个更好

SELECT (SELECT COUNT(1) from tbl) AS Total,*
FROM tbl
