语法错误:WITH在此位置无效输入

Question

所以我有类似的要求

    WITH customers_in_usa AS (
        SELECT 
           customerName, state
        FROM
           customers
        WHERE
           country = 'USA'
    ) SELECT 
        customerName
    FROM
        customers_in_usa
    WHERE
        state = 'CA'
    ORDER BY customerName;

但是在写入时我发现了一个错误:'WITH在此位置无效输入' error_picture.你能帮我理解这段代码中的错误吗？

Answer 1

WITH customers_in_usa AS现在是无效的MySQL代码.MySQL将在MySQL版本8中支持CTE.

您可以重写SQL代码,这应该给出相同的结果.

SELECT 
    customerName
  , state
FROM 
   customers 
WHERE
   country = 'USA'
 AND
   state = 'CA'
ORDER BY
   customerName
