[英]Search ids in comma separated string with an input comma separated string
Consider the table tasks 考虑表任务
id | assigned_to | viewers
1 100 100,200,300
2 200 125,200,310
3 300 175,250,300
4 400 400,440,670
5 500 500,111,333
I will get an input string that may contain more than 1000 comma separated values, like 我将得到一个可能包含1000多个逗号分隔值的输入字符串,例如
1,2,3,4,5,6,7,8,,,,100,,,,500,,,,1000
I want to get all the rows from the table that are matching to " assigned_to " or " viewers " from the input string. 我想从表中获取与输入字符串中的“ assigned_to ”或“ viewers ”匹配的所有行。 I have tried with IN() for " assigned_to ", 我尝试使用IN()作为“ assigned_to ”,
SELECT * FROM tasks WHERE assign_to IN ($inputString)
but then couldn't get any solution to match with " viewers " column. 但随后无法获得与“ 查看者 ”列匹配的任何解决方案。
Is there any way to match a comma separated string with another comma separated string? 有什么办法可以将逗号分隔的字符串与另一个逗号分隔的字符串进行匹配?
Thanks in advance 提前致谢
You can try the following code: 您可以尝试以下代码:
$str = "SELECT * FROM tasks WHERE assign_to IN ($inputString) ";
$values = explode(",",$inputString);
foreach ($values as $val) {
$str .= "AND viewers LIKE ".$val; //Replace AND with OR as per your requirement (Match all/ match any)
}
//execute query
This is not very efficient but would do the task. 这不是很有效,但是可以完成任务。
