如何在 mariadb 10.1 中替换“with”语句

Question

我在 MariaDB 10.1 中使用第三方软件如何替换 sql "with" 语句（不适用于 MariaDB 10.1）？

我想做这样的事情:

WITH mCte
AS (
  SELECT 
     @row_num: = @row_num + 1 AS Cpt
    ,field1
  FROM (
    SELECT @row_num: = 0 AS row_num
      ,myField AS field1
    FROM myTable
    ) AS T
  )
SELECT *
FROM mCte
WHERE Cpt BETWEEN 1 AND 5

谢谢

我建议：

select @row_num := @row_num + 1 AS Cpt, field1
from myTable t cross join
     (select @row_num := 0 as row_num) params
limit 5;

通常，我希望查询中有 order by，但您的代码没有。
