在MY SQL中插入包含多个select语句的表

Question

我的查询结果如下：

+------------------+------------+
| meta_key         | meta_value |
+------------------+------------+
| Destination Name | Shivapuri  |
| Destination Date | 26/03/2012 |
+------------------+------------+

我正在尝试编写一个select语句，其列名为Destination Name和Destination Date，其各自的值为Shivapuri和'26 / 03/2012'。如何在MY SQL中使用查询？

Answer 1

这些方面应该做的事情 -

SELECT
    GROUP_CONCAT(IF(meta_key = 'Destination Name', meta_value, NULL)) AS `Destination Name`,
    GROUP_CONCAT(IF(meta_key = 'Destination Date', meta_value, NULL)) AS `Destination Date`
FROM tbl_name
GROUP BY record_identifier

Answer 2

SELECT 
    (CASE WHEN meta_key = 'Destination Name' THEN meta_value END) as name,
    (CASE WHEN meta_key = 'Destination Date' THEN meta_value END) as date
FROM `yourtable`
