select SUM 求和中带模糊查询怎么弄?
$sql="select username,SUM(IF(types = 1, smoney, 0)) as t1 from record where 1=1".$s1." GROUP BY username";
现在得出的结果是:record 表中username = username的 types 字段 = 1 的 smoney 字段的总和 被赋值为变量 $t1
我想换一个查询条件
希望得出结果是:record 表中username = username的 以及 regfrom 字段中包含 nameuser 的 types 字段 = 1 的 smoney 字段的总和 被赋值为变量 $t1
请问sql语句该怎么写。数据库截图:
回复讨论(解决方案)
包含 nameuser 的 是什么意思?
比如用户admin 查询就查询到 nameuser 这个字段中admin的信息
$username=$_REQUEST['username'];
例:
查询用户为admin
username字段中等于admin
以及 regfrom 字段中包含 admin的
得出的结果为:10+10+20+30+20
查询用户为b123456
username字段中等于b123456
以及 regfrom 字段中包含 b123456 的
得出的结果为:20+30+20
$username=$_REQUEST['username'];$sql="select username, SUM(smoney) as t1 from record where username='$usename'";
regfrom 字段中还要包含 $usename 这一段没有呢?
把条件加上不就行了么?
regfrom 字段中还要包含 $usename 这一段没有呢?
举一反三一下不就有了。
$sql="select username, SUM(smoney) as t1 from record where username='$usename' or instr(regfrom, '$username') >0";
