[ZT] 一个常见的问题源自于试图使用MySQL内置的数据类型或函数名同名的列来创建数据库表，例如TIMESTAMP或GROUP。你允许这样做(例如，ABS是一个允许的列名)，但是当使用其名字也是列名的函数时，在一个函数名和“ ( ”之间不允许白空。下列词明确地在MySQL中被保留。他们的大多数被 ANSI SQL92 禁止作为列或表名(例如，group)。一些被保留因为MySQL需要他们并且正在(当前)使用一个yacc分析器： action add aggregate all alter after and as asc avg avg_row_length auto_increment between bigint bit binary blob bool both by cascade case char character change check checksum column columns comment constraint create cross current_date current_time current_timestamp data database databases date datetime day day_hour day_minute day_second dayofmonth dayofweek dayofyear dec decimal default delayed delay_key_write delete desc describe distinct distinctrow double drop end else escape escaped enclosed enum explain exists fields file first float float4 float8 flush foreign from for full function global grant grants group having heap high_priority hour hour_minute hour_second hosts identified ignore in index infile inner insert insert_id int integer interval int1 int2 int3 int4 int8 into if is isam join key keys kill last_insert_id leading left length like lines limit load local lock logs long longblob longtext low_priority max max_rows match mediumblob mediumtext mediumint middleint min_rows minute minute_second modify month monthname myisam natural numeric no not null on optimize option optionally or order outer outfile pack_keys partial password precision primary procedure process processlist privileges read real references reload regexp rename replace restrict returns revoke rlike row rows second select set show shutdown smallint soname sql_big_tables sql_big_selects sql_low_priority_updates sql_log_off sql_log_update sql_select_limit sql_small_result sql_big_result sql_warnings straight_join starting status string table tables temporary terminated text then time timestamp tinyblob tinytext tinyint trailing to type use using unique unlock unsigned update usage values varchar variables varying varbinary with write when where year year_month zerofill 下列符号(来自上表)被ANSI SQL禁止但是被MySQL允许作为列/表名。这是因为这些名字的一些是很自然的名字并且很多人已经使用了他们。 ACTION BIT DATE ENUM NO TEXT TIME TIMESTAMP
first～你的id是PK，不要用null来插 second 如果你的要用到保留字做表名或字段名，可以用 ` 符号来括起来引用，当然不推荐你这样做last 代码整理一下
$query="INSERT INTO '$table' (id,title,comment,date,num) values (NULL,'$title','$comment','$date','')"; => $query="INSERT INTO `$table` (title,comment,date,num) values ('$title','$comment','$date','')"; 如果你的id是自动增长型的primary key，I think u define it so
$query="INSERT INTO `$table` (id,title,comment,date,num) values (NULL,'$title','$comment','$date','')"; `为Esc键下面的和1左边的键
id int(11) autoincrement;primay key
title varchar(100);
comment mediumtext;
date varchar(10);
num int(11);
大哥们再帮我看看吧.
添加失败2You have an error in your SQL syntax near 'or,num) values (NULL,'test','test','1060594114','0','')' at line 1
你可以选择继续
或者注销
大哥们帮我看看.
<?php
$table = $_REQUEST["select"];
$leibie = $_REQUEST["select1"];
$title = $_REQUEST["title"];
$comment = $_REQUEST["comment"];
$date = time();
if($title==""||$comment=="")
{
echo "资料不完整,请返回重新填写";
exit();
}
else
{
$link=mysql_connect("localhost","root","21508926");
mysql_select_db("meet",$link);
if($table=='about'||$table=='lilun'||$table=='library'||$table=='notice')
{
if ($leibie==0)
{
$query="INSERT INTO $table (id,title,comment,date,num) values (NULL,'$title','$comment','$date','')"; $result=mysql_query($query);
if($result)
{
echo "添加成功1";
} else{
echo "添加失败1";
echo mysql_error();
}
}
else{
echo "你的选择有错";
exit();
}
}
else {
$query="INSERT INTO mainos (id,title,comment,date,or,num) values(NULL,'$title','$comment','$date','$leibie','')"; $result=mysql_query($query);
if($result)
{
echo "添加成功2";
}
else
{
echo "添加失败2";
echo mysql_error();
}
}
}
mysql_close($link);
echo "<br>你可以选择<a href='manage.php'>继续</a>";
echo "<br>或者<a href='logout.php'>注销</a>";
?>
1)如果要把一个空值放到表里还不如直接在表里将其设为NULL;
2)$table不用再加引号了;
3)mysql_query($query,$link);这句话有用么？
4）$query="INSERT INTO mainos (id,title,comment,date,or,num) values (NULL,'$title','$comment','$date','$leibie','')";这句话里居然有个字段叫or;我不知道这样一个字段能否使用？
mysql_query($query,$link)可以直接写在if的条件里,这个不是大问题吧;
还有就是or这个字段是meet数据库里面的一个表mainos比其他的表多出来的一个字段,是为了区别文章用的,难道一个数据库里的表结构必须一样吗?
还是有问题.
不知道是不是这个的问题.
提交的$leibie的值有三个:1,2,3.
帮帮忙
容易产生错误!
