試圖逃脫單引號和雙引號的PHP MySQL查詢

Question

你好，並提前感謝您的任何幫助。

當我將查詢全部粘貼到phpMyAdmin中時，我得到結果集。當我嘗試在PHP腳本中運行查詢時，出現PHP錯誤。我認爲問題在於我如何逃避代碼的MySQL語句部分中的單引號（撇號）。任何人都可以推薦一個轉義方法來用於這個精心設計的MySQL查詢。

下面是MySQL的代碼的一部分作爲在phpMyAdmin（它工作正常）進入....

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... 

... ...

這裏就是我試圖添加代碼來運行數據庫查詢PHP腳本的一部分...

$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; 

或者如果可能的話：拆分查詢成更小的子查詢，這將提高可讀性和可能的​​表現也是如此。
