php 裡一個sql語句太長，調式時發現sql語句變得不完整了

PHP高手們，幫我解決一個問題吧：
在php裡定義了一條sql如下：
$sql = "SELECT * FROM p_info pi LEFT JOIN job j ON j.id = " . $id .
"WHERE pi.requestid = 0
AND ((ifnull(pi.standard_20_ft_container, 0) - ifnull(j.standard_20_ft_container, 0)) <= 0)
AND ((ifnull(pi.standard_40_ft_container, 0) - ifnull(j.standard_40_ft_container, 0)) <= 0)
AND ((ifnull(pi.high_cube_40_ft_container, 0) - ifnull(j.high_cube_40_ft_container, 0)) <= 0)
AND ((ifnull(pi.capacity_head_of_cattle, 0) - ifnull(j.capacity_head_of_cattle, 0)) <= 0)
AND ((ifnull(pi.capacity_head_of_sheep, 0) - ifnull(j.capacity_head_of_sheep, 0)) <= 0)
AND ((ifnull(pi.capacity_other_livestock, 0) - ifnull(j.capacity_other_livestock, 0)) <= 0)
AND ((ifnull(pi.capacity_number_of_horses, 0) - ifnull(j.capacity_number_of_horses, 0)) <= 0)
AND ((ifnull(pi.grain_feed_kg, 0) - ifnull(j.carrying_capacity_kg, 0)) <= 0)
AND ((ifnull(pi.length_cm, 0) - ifnull(j.tray_length_cm, 0)) <= 0)
AND ((ifnull(pi.width_cm, 0) - ifnull(j.tray_width_cm, 0)) <= 0)
AND ((ifnull(pi.height_cm, 0) - ifnull(j.max_load_height_cm, 0)) <= 0)
AND ((ifnull(pi.weight_kg, 0) - ifnull(j.carrying_capacity_kg, 0)) <= 0)
AND to_days(j.home_day1) <= to_days(str_to_date(pi.date1, '%d/%m/%Y'))
AND to_days(str_to_date(pi.date2, '%d/%m/%Y')) <= to_days(j.home_day2)
但是查詢出的資料為空，調式時發現，傳到$query = mysql_query ( $sql );這裡的sql語句變成這樣了：
SELECT * FROM p_info pi LEFT JOIN job j ON j.id = 734WHERE pi.requestid = 0
AND ((ifnull(pi.standard_20_ft_container, 0) - ifnull(j.standard_20_ft_container, 0)) <= 0)
AND ((ifnull(pi.standard_40_ft_container, 0) - ifnull(j.standard_40_ft_container, 0)) <= 0)
AND ((ifnull(pi.high_cube_40_ft_container, 0) - ifnull(j.high_cube_40_ft_container, 0)) <= 0)
AND ((ifnull(pi.capacity_head_of_cattle, 0) - ifnull(j.capacity_head_of_cattle, 0)) <= 0)
AND ((ifnull(pi.capacity_head_of_sheep, 0) - ifnull(j.capacity_head_of_sheep, 0)) <= 0)
AND ((ifnull(pi.capacity_other_livestock, 0) - ifnull(j.capacity_other_livestock, 0)) <= 0)
AND ((ifnull(pi.capacity_number_of_horses, 0) - ifnull(j.capacity_number_of_horses, 0)) <= 0)
AND ((ifnull(pi.grain_feed_kg, 0) - ifnull(j.carrying_capacity_kg, 0)) <= 0)
AND ((ifnull(pi.length_cm, 0) - ifnull(j.tray_length_cm, 0)) <= 0)
AND ((ifnull(pi.width_cm, 0) - ifnull(j.tray_width_cm, 0)) <= 0)
AND ((ifnull(pi.height_cm, 0) - ifnull(
貌似後面的就被截斷了，資料庫裡執行這個sql是沒問題的。但是在這裡就有問題，怎麼辦呢？大家有遇到這樣問題嗎？
