MySQL錯誤 - 查詢爲空

Question

Starnge問題我不能似乎發現的根，

我使用的jqGrid這對於更新編輯提交數據並刪除我的網頁server.php

因爲有時值空的我已經在switch語句下編寫了更新/插入函數的代碼。

switch語句運行之前，我有代碼生成mySQL的更新和插入語句。

插入語句運行我回聲出SQL調用，它返回就在：

my insert = INSERT INTO mapdata_mdt (id_etp,geoaddr_mdt,active_mdt,flag_mdt) VALUES(1 ,'n11hl' ,1 ,1) 

據我可以acertain這就是一個有效的SQL查詢???所以爲什麼它錯誤與以下內容：

Error: Query was empty 

我對此感到困惑，所以任何指針將受到重視。

完整代碼如下：

if (!function_exists("GetSQLValueString")) { 
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{ 
    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue; 

    $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue); 

    switch ($theType) { 
    case "text": 
     $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL"; 
     break;  
    case "long": 
    case "int": 
     $theValue = ($theValue != "") ? intval($theValue) : "NULL"; 
     break; 
    case "double": 
     $theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" : "NULL"; 
     break; 
    case "date": 
     $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL"; 
     break; 
    case "defined": 
     $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue; 
     break; 
    } 
    return $theValue; 
} 
}

你有mysql_query調用mysql_query：

if (!mysql_query(mysql_query($myInsert, $growth_conn))){
