使用 Laravel 查询构建器排除某些字符串

Question

Let us say I have a table named table and it has the column called path , the string format in the path is like following

row path
1   /path1/aa/bg/c/da
2   /path1/ab/v
3   /path1/a/ba/ca

As you can see, each segment is separated by the char / . How to format the condition in the where using like so that the only row returned is row 2 with 2 slashes .

I tried DB::table('table')->where('path','LIKE','/path1/%/%')->get()

But the query above will return all the rows due to the last % . How can I exclude / after the last % so that, the record which has the char / after the last % will not be included in the result ?

Answer 1

if you ar looking for match one character:

DB::table('table')->where('path','LIKE','/path1/_/_')->get()

"test%" matches all characters after

"%test" matches all characters before

"_" matches one character

ELSE if the string lenght you are matching is variable, you can only use regular expressions,

select * from table where path REGEXP '\/path1\/[a-zA-Z0-9_]+\/[a-zA-Z0-9_]+'

more generic match matching special characters:

select * from table where path REGEXP '\/path1\/.+\/.+'
