Question

所以我有这种方法，它包含来自mysql的几何函数：

select *, (SELECT SUM(t_o.value) FROM tree_operations t_o WHERE t_o.operation_id = operations.id) operationTreeValue, (SELECT COUNT(t_o.id)  FROM `tree_operations` t_o WHERE t_o.operation_id = operations.id) operationTreeNumber, (CASE\r                          WHEN operations.type = 'pieces' THEN (SELECT GROUP_CONCAT(p.name) FROM `pieces` p WHERE p.id IN (SELECT piece_id FROM `piece_row_operations` WHERE operation_id = operations.id))\r                          WHEN operations.type = 'rows' THEN (SELECT GROUP_CONCAT(r.number) FROM `rows` r WHERE r.id IN (SELECT row_id FROM `piece_row_operations` WHERE operation_id = operations.id))\r                          END) AS typeName from `operations` where operations.id IN (SELECT t_o.operation_id FROM `tree_operations` t_o WHERE t_o.tree_id IN (SELECT t.id FROM `trees` t WHERE t.coordinates IN (Contains(GeomFromText('POLYGON(49.816472 35.971209,49.7868 35.970981,49.788668 35.947219,49.15201 35.947905,49.816472 35.971209)'))))) order by `operations`.`id` desc

但是令人惊讶的是，它在服务器上不起作用（尽管在本地完全可以）在花费大量时间（在不同环境中运行查询等）之后，我无法得到任何可靠的答案。我的查询有什么问题吗？还是不再起作用的功能？ p.s：我的本地mysql版本是5.7，服务器是mariadb 10.2

Answer 1

自MySQL 5.7.6起，不再支持某些MySQL函数，如GeomFromText（）；

改用MariaDB @ latest && ST_GeomFromText（）和ST_（其他函数）

Mysql函数CONTAINS和GEOMFROMTEXT不起作用
