我知道Stackoverflow上有很多与自定义错误处理程序相关的问题.但是,在阅读了其中许多内容以及PHP手册之后,我仍然无法解决我的问题.因此我发布了这个问题.

我的脚本目前以这种方式构建:

require 'file.php';
require 'anotherFile.php';
// several more "require" here. These files contain many functions

function myErrorHandler($errno, $errstr, $errfile, $errline, $errcontext){
    // some code to handle errors here

}

class myObject {
    function __construct() {
        // set the values here
    }

    function computeSomething() {
        ...
        doFunction2();
        ...
    }

    function SomethingBadHappened()
    {
    }
}

function doFunction1() {
    // for some reason, an error happens here
    // it is properly handled by the current error handler
}

function doFunction2() {
    // …

我试图在phpmyadmin网络托管服务器中运行SP,但总是得到以下错误

1064 - 您的SQL语法出错; 检查与MySQL服务器版本对应的手册,以便在第4行的''附近使用正确的语法

我试图运行的SP是:

CREATE PROCEDURE Authenticate_UserByEmailID(strUsername VARCHAR(45), strPassword VARCHAR(45))
BEGIN
    SELECT * FROM users 
    WHERE users.Username = strUsername AND users.Password = strPassword;
END $$

我尝试在SP名称,表名列名称和不同的其他组合引号中添加单引号但没有结果然后我遇到此链接并尝试更改分隔符但没有结果.你能帮忙吗？

解:

对不起伙计我的坏人.我添加了分隔符,为我解决了这个问题.

DELIMITER ;;

CREATE PROCEDURE `Authenticate_UserByEmailID`(strUsername VARCHAR(45), strPassword VARCHAR(45))
BEGIN
    SELECT * FROM DBCompany_samsonusac517644.users 
    WHERE Username = strUsername AND Password = strPassword;
END ;;

我是MySQL的新手.我正在尝试编写一个在表中插入行的查询,但前提是在5分钟前插入了上一行.另外,我希望我的PHP代码能够知道是否插入了数据.这是我的尝试:

IF (SELECT max(EntryDate) from MyTable) < DATE_SUB(CURRENT_DATE() INTERVAL 5 MINUTE) THEN
   INSERT INTO MyTable (...) values (...)
ELSE
   Select false
END IF

不幸的是,但并不奇怪,这会产生语法错误(错误对于问题的位置非常模糊).

我做了些蠢事吗？

我正在使用mysql db(版本5.5)并使用mysql查询浏览器(v 1.1.5).但是当我尝试使用查询浏览器创建一个简单的表时出现以下错误:

CREATE TABLE `tstaks`.`employee` (
  `empid` INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
  `name` VARCHAR(45) NOT NULL,
  PRIMARY KEY(`empid`)
)
TYPE = InnoDB;


mysql error no 1064
you have an error in your sql sytax,check the manual that corresponds to your mysqlserver version for right syntax to use
near type ='innoDB

我在这个查询中找不到错误:

INSERT INTO realestate ( 
type, offer, seller, area, build_area, price, is_negotiable, fur, floor_num, rooms, baths, year_built, phone, title, describe 
) VALUES ( 
'2', '1', '1', '98', '99887', '3242839', 'true', 'true', '1', '1', '1', '2010', '97854984576', 'lksehjfsed', 'alidjaopdhkljhdfkedfhwekdfhwseldfk' )

这是我得到的错误消息:

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 'describe ) VALUES ( '2', '1', '1', '98', '99887', '324' at line 2

我正在尝试根据我的软件中的说明设置表.这就是我输入的内容:

CREATE TABLE `swd_account` (
`pk_account` int(11) NOT NULL auto_increment,
`name` char(16) NOT NULL default '',
`isact` tinyint(4) NOT NULL default '1',
PRIMARY KEY (`pk_account`)
) TYPE=MyISAM;

`pk_user` int(11) NOT NULL auto_increment,
`fk_account` int(11) NOT NULL default '0',
`email` varchar(40) NOT NULL default '',
`name` varchar(40) default NULL,
`isact` tinyint(4) NOT NULL default '1',
`datereg` date default NULL,
`days` tinyint(4) default '0',
`datelastsend` date default NULL,
`messlastsend` int(11) default NULL,
`countsend` int(11) NOT NULL default '0', …

JS

function blueSky() {
$.ajax({
type:'GET',
url: 'test.php',
success: function(respond) { 
  document.getElementById("div02").innerHTML=respond;  // works
}
});
$("#div01").html("<?php echo $target;?>"); }   // should be "abc" - doesn't work

test.php的

...    
$target = "abc";

你好，我正在使用 MySQL 创建一个函数：

CREATE FUNCTION INSERTGROUP(name VARCHAR(50))
RETURNS INT
NOT DETERMINISTIC
BEGIN
DECLARE 'idGroup' INT;

IF (NOT EXISTS (SELECT groupID FROM groupsTable WHERE groupName = 'name'))
THEN INSERT INTO groupsTable (groupName) VALUES ('name');

SELECT groupID INTO 'idGroup' FROM groupsTable WHERE groupName='name';

RETURN 'idGroup';
END//

但是当我尝试创建它时出现此错误：

ERROR 1064 (42000): 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
''idGroup' INT;

IF (NOT EXISTS (SELECT groupID …
