尝试转义PHP MySQL查询的单引号和双引号

Question

您好，谢谢您的协助。

当我将查询全部粘贴到phpMyAdmin中时，得到结果集。 当我尝试在PHP脚本中运行查询时，出现PHP错误。 我认为问题出在我如何在代码的MySQL语句部分内转义单引号（撇号）。 任何人都可以推荐一种转义方法用于这种冗长的MySQL查询。

这是在phpMyAdmin中输入的MySQL代码的一部分（正常工作）。

SET SESSION group_concat_max_len = 2000000;
SET @radius = .014;
select
cast(concat('{"type":"Feature","id":"',t2.TerrID,'","properties":    {"name":"',t2.TerrName,'","density":',t2.TotalOpp2,',"color":"',t2.TerrClr,'"},','"geometry"    :{"type":"MultiPolygon","coordinates":[', t2.tett2,']}},')as char) as tett
from(

select TerrName,
TerrID,
sum(TotalOpp) as TotalOpp2,
AgentsAssigned,
(sum(TotalOpp) - AgentsAssigned * 60) as density,
if((sum(TotalOpp) - AgentsAssigned * 60)<0,"red", if((sum(TotalOpp) - AgentsAssigned *     60)<60,"yellow","green")) as TerrClr,
group_concat(tett) as tett2

from(

SELECT
territories.territory_name as TerrName,
territories.territoryID as TerrID,
territories_meta.tm_color,
territories.territory_description,
territories.territory_state,
GROUP_CONCAT(distinct(territories_zips.tz_zip)SEPARATOR ', ' ) AS ZipCodes,
GROUP_CONCAT(distinct(concat(users.user_Fname,' ',users.user_Lname))SEPARATOR ', ') AS     AgentName,
users.user_role,
round(sum(boundaries_meta.bm_opportunity)/Count(distinct(territories_assign.ta_repID)))     AS TotalOpp,
Count(distinct(territories_assign.ta_repID)) AS AgentsAssigned,
group_concat(boundaries.boundary_geometry)as tett
FROM
territories
INNER JOIN territories_zips ON territories.territoryID = territories_zips.tz_terrID
INNER JOIN territories_assign ON territories.territoryID =     territories_assign.ta_territoryID...

……

这是我试图将代码的那部分添加到运行数据库查询的PHP脚本中的地方...

$places_zipopps_terr3 = $db->query('SET SESSION group_concat_max_len = 2000000;
SET @radius = .014;
select
cast(concat(\'{"type":"Feature","id":"\',t2.TerrID,\'","properties":    {"name":"\',t2.TerrName,\'","density":\',t2.TotalOpp2,\',"color":"\',t2.TerrClr,\'"},\',\'"g    eometry":{"type":"MultiPolygon","coordinates":[\', t2.tett2,\']}},\')as char) as tett
from(

select TerrName,
TerrID,
sum(TotalOpp) as TotalOpp2,
AgentsAssigned,
(sum(TotalOpp) - AgentsAssigned * 60) as density,
if((sum(TotalOpp) - AgentsAssigned * 60)<0,"red", if((sum(TotalOpp) - AgentsAssigned *     60)<60,"yellow","green")) as TerrClr,
group_concat(tett) as tett2

from(

SELECT
territories.territory_name as TerrName,
territories.territoryID as TerrID,
territories_meta.tm_color,
territories.territory_description,
territories.territory_state,
GROUP_CONCAT(distinct(territories_zips.tz_zip)SEPARATOR \', \' ) AS ZipCodes,
GROUP_CONCAT(distinct(concat(users.user_Fname,\' \',users.user_Lname))SEPARATOR \', \')         AS AgentName,
users.user_role,
round(sum(boundaries_meta.bm_opportunity)/Count(distinct(territories_assign.ta_repID)))     AS TotalOpp,
Count(distinct(territories_assign.ta_repID)) AS AgentsAssigned,
group_concat(boundaries.boundary_geometry)as tett
FROM
territories
INNER JOIN territories_zips ON territories.territoryID = territories_zips.tz_terrID
INNER JOIN territories_assign ON territories.territoryID =     territories_assign.ta_territoryID...

使用nowdoc字符串：

$query = <<<'EOT'
SET SESSION group_concat_max_len = 2000000;
SET @radius = .014;
select
cast(concat('{"type":"Feature","id":"',t2.TerrID,'","properties":    {"name":"',t2.TerrName,'","density":',t2.TotalOpp2,',"color":"',t2.TerrClr,'"},','"geometry"    :{"type":"MultiPolygon","coordinates":[', t2.tett2,']}},')as char) as tett
from(

select TerrName,
TerrID,
sum(TotalOpp) as TotalOpp2,
AgentsAssigned,
(sum(TotalOpp) - AgentsAssigned * 60) as density,
if((sum(TotalOpp) - AgentsAssigned * 60)<0,"red", if((sum(TotalOpp) - AgentsAssigned *     60)<60,"yellow","green")) as TerrClr,
group_concat(tett) as tett2

from(

SELECT
territories.territory_name as TerrName,
territories.territoryID as TerrID,
territories_meta.tm_color,
territories.territory_description,
territories.territory_state,
GROUP_CONCAT(distinct(territories_zips.tz_zip)SEPARATOR ', ' ) AS ZipCodes,
GROUP_CONCAT(distinct(concat(users.user_Fname,' ',users.user_Lname))SEPARATOR ', ') AS     AgentName,
users.user_role,
round(sum(boundaries_meta.bm_opportunity)/Count(distinct(territories_assign.ta_repID)))     AS TotalOpp,
Count(distinct(territories_assign.ta_repID)) AS AgentsAssigned,
group_concat(boundaries.boundary_geometry)as tett
FROM
territories
INNER JOIN territories_zips ON territories.territoryID = territories_zips.tz_terrID
INNER JOIN territories_assign ON territories.territoryID =     territories_assign.ta_territoryID...
EOT;

或者，如果可能的话：将查询拆分为较小的子查询，这将提高可读性并可能还会提高性能。
