找不到sql語法錯誤

Question

任何人都可以發現我的語法錯誤嗎？我是新的SQL查詢。此代碼是在我的項目在其他地方使用，我重新格式化它我創建的新表，但我得到了下面的錯誤吧：

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FROM tbl_prescriptions ta, tbl_prescriptions_type tat, tbl_prescriptions_subtype' at line 1 QUERY:SELECT ta.pk_id, ta.date, tat.vch_type as vch_type_name, tar.vch_subtype as vch_subtype_name, concat(tas.vch_first_name, ' ', tas.vch_last_name) as vch_resource_name, FROM tbl_prescriptions ta, tbl_prescriptions_type tat, tbl_prescriptions_subtype tar, tbl_resources tas WHERE ta.fk_type_id = tat.pk_id AND ta.fk_resource_id = tas.pk_id AND ta.fk_subtype_id = tar.pk_id AND ta.fk_patient_id = 359 ORDER BY date DESC;

$sqlPrescriptionQuery = "SELECT ta.pk_id, ta.date, "; 
$sqlPrescriptionQuery .= "tat.vch_type as vch_type_name, "; 
$sqlPrescriptionQuery .= "tar.vch_subtype as vch_subtype_name, "; 
$sqlPrescriptionQuery .= "concat(tas.vch_first_name, ' ', tas.vch_last_name) as vch_resource_name, "; 
$sqlPrescriptionQuery .= "FROM tbl_prescriptions ta, tbl_prescriptions_type tat, tbl_prescriptions_subtype tar, tbl_resources tas "; 
$sqlPrescriptionQuery .= "WHERE "; 
$sqlPrescriptionQuery .= "ta.fk_type_id = tat.pk_id AND "; 
$sqlPrescriptionQuery .= "ta.fk_resource_id = tas.pk_id AND "; 
$sqlPrescriptionQuery .= "ta.fk_subtype_id = tar.pk_id AND "; 
$sqlPrescriptionQuery .= "ta.fk_patient_id = ".$row['pk_id']." "; 
$sqlPrescriptionQuery .= "ORDER BY date DESC;"; 

$counter = 0; 

$prescriptionresult = mysql_query($sqlPrescriptionQuery) or die(mysql_error()."<br>QUERY:".$sqlPrescriptionQuery); 

謝謝！

Answer 1

你有一個逗號在這裏結束太多：

$sqlPrescriptionQuery .= "concat(tas.vch_first_name, ' ', tas.vch_last_name) as vch_resource_name, "; 

它應該是：

$sqlPrescriptionQuery .= "concat(tas.vch_first_name, ' ', tas.vch_last_name) as vch_resource_name "; 

Answer 2

$sqlPrescriptionQuery = " 
SELECT ta.pk_id 
    , ta.date 
    , tat.vch_type vch_type_name 
    , tar.vch_subtype vch_subtype_name 
    , CONCAT(tas.vch_first_name, ' ', tas.vch_last_name) vch_resource_name 
    FROM tbl_prescriptions ta 
    , tbl_prescriptions_type tat 
    , tbl_prescriptions_subtype tar 
    , tbl_resources tas 
WHERE ta.fk_type_id = tat.pk_id 
    AND ta.fk_resource_id = tas.pk_id 
    AND ta.fk_subtype_id = tar.pk_id 
    AND ta.fk_patient_id = $row['pk_id'] 
ORDER 
    BY date DESC; 
    ";
