我想将mysql查询结果导出到csv文件中,但是我发现csv文件的格式有问题。
输入:
COMPANY AMOUNT VENDOR_NAME
C1 70000 A
C2 6000 A
C3 2000 A
C2 39000 B
C3 4000 B
C3 40000 C
输出:
VENDOR_NAME C1 C2 C3 Total
A
正如标题所说,非常简单的脚本,我以前从来没有遇到过这个问题。只是为新闻系统获取数据。我正在测试的id在数据库中是"2“。但是如果我执行article.php?id=2fjfkhshs,它会显示id为"2“的信息,而不是错误。"id“是数据库中的A_I主整数。
<?php
$nid = mysql_real_escape_string($_GET['id']);
$newsQuery = mysql_query("SELECT * FROM news WHERE id = '$ni
无法执行查询语句不正确的字符串值:行% 1的列'member‘的\x96\xBC\x91O\x82\xCD...。以下是代码。
$member=stripslashes($_POST["membername"]);
$link=mysql_connect(localhost,$username, $password) or die("unable to connect to database ".mysql_error());
mysql_set_charset('utf8', $link);

我可以使用以下行连接到mysql:
mysql -u myusername -p
(enters password into terminal)
>>>Welcome to the MySQL monitor. Commands end with ; or \g.
>>>Your MySQL connection id is 51
>>>Server version: 5.6.10-log Source distribution
下面是我的主目录(not /etc/my.cnf)中的.my.cnf:
[client]
user = myu
我在尝试保存一些Tweets时得到了以下异常,
造成原因: com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1055):不正确的字符串值:'\xF3\xBE\x8D\x81‘,列'twtText’位于第1行,在com.mysql.jdbc.SQLError.createSQLException(SQLError.java:956) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:3491) at com.mysql.jdbc.MysqlIO.che
可能重复:
我是PHP新手,我想确认一下。如果我将mysql_real_escape_string用于用户生成的输入(变量),查询将不会被黑?
示例脚本:
// Getting Unique ID
$sql = "select `Person_id` from `accounts` where `username` = '$username'";
$query = mysql_query($sql) or die ("Error: ".mysql_error());
while ($row = mysql_fetch_array($qu
这是原始的MySQL查询:
UPDATE jos_bully_table AS jbt1
INNER
JOIN ( SELECT jbt2.bully_concat_name,
COUNT(*) AS b_name_count
FROM jos_bully_table AS jbt2
GROUP
BY jbt2.bully_concat_name
) AS jbt3
ON jbt3.bully_concat_name = jbt1.bully_concat_name
在step 5.7 -> 8.0.23中将mysql从5.6 -> 5.7 -> 8.0.23升级时,我收到一个警告: The following objects use the utf8mb3 character set. It is recommended to convert them to use utf8mb4 instead, for improved Unicode support.

我遇到了一个非常奇怪的解析错误,它说在第21行上有意外的。代码:
mysql_connect("$host","$username","$passowrd") or die ("Data server is inaccesible);

$userquery = mysql_query("SELECT * FROM login WHERE activated=
