mySQL错误-查询为空

如何解决mySQL错误-查询为空

| 我似乎找不到根源的Starnge问题， 我正在使用jqgrid提交数据以进行更新编辑和删除到我的页面server.php 因为有时值是空的，所以我在switch语句下为update / insert函数编写了代码。 在运行switch语句之前，我有为mySQL生成更新和插入语句的代码。 在插入语句运行之前，我回显了返回的SQL调用：

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

据我可以确定多数民众赞成在一个有效的SQL查询？？？那么为什么会出现以下错误：

Error: Query was empty

我对此感到困惑，因此任何指针将不胜感激。 完整的代码如下：

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;
}
}

解决方法

您有

mysql_query

呼叫

mysql_query

：

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