Question

朋友们，我的问题是我有一些excel表格上传到数据库，然后将检索并发布到门户网站上。

我的问题是我无法查询此图片中标记的特定数据

任何人都可以帮我查询没有'％'的数字[全部]并将它们分配给变量.....

<?php

$con = mysql_connect("localhost","root","");

if(!$con)die (msql_error());

$db = mysql_select_db("csv");

if(!$db) die(mysql_error());

$query = mysql_query("select * from users");

$rows = mysql_fetch_array($query);

您可以使用trim功能来摆脱＆＃39;％＆＃39;字符。

我编写了以下测试代码：

$test = "15%";
echo trim($test,"%");

----------FULL TEST--------------

$test = "15%"; //test case
echo "Test:".trim($test,"%")."</br>";

$rows = array('1%','2%','3%');
$aux = array();

foreach($rows as $key)
{
echo trim($key,"%")."</br>"; //just output
$aux[] = trim($key,"%"); //or transforming
}

var_dump($aux);

Mysql版本：

set @test = "15%";
select trim(BOTH '%' FROM @test);

#Retrieve all rows but first
select name,trim(BOTH '%' FROM lastname) as normal,trim(BOTH '%' FROM email) as high 
from users limit 1,1000;


#select row based on Normal %
select name, trim(BOTH '%' FROM lastname) as normal,trim(BOTH '%' FROM email) as high
from users
where trim(BOTH '%' FROM lastname) = 5;
