How to count how many times a string appears in a field in mySQL separated by comma?

Question

My mySQL is like this, an id , and a texts that have may phrases and some identical as below:

id      texts
2       abc,fd4g,oigdu,abc,abc
3       ccc,fff,fff,ccc,iop

My question is how can I show using PHP/mySQL

1. per id

2 - abc - 3 times

2 - fd4g - 1 times

2 - oigdu - 1 times

3 - ccc - 2 times

3 - fff - 2 times

3 -iop - 1 times

2. or searching via the text

   abc - 2 times - 2

   fd4g - 1 times - 2

   oigdu - 1 times - 2

   ccc - 2 times - 3

   fff - 2 times - 3

   iop - 1 times - 3

-

If my mySQL structure was :

id      texts
2       abc
2      fd4g
2      oigdu
2      abc
2      abc
3       ccc
3      fff
3      fff
3      ccc
3      iop

would this be easier?

Answer 1

The second structure would be easier. But you shouldn't name your first column id because the id -field usually has unique key values, that means only auto-incrementing values. You have multiple times the same number, so you it's obviously not unique but something different.

With the other query you could run

SELECT id, texts, COUNT(*) FROM tbl group by id, texts

and your result would be

2  |  abc  |  3
2  | fd4g  |  1

and so on.

Answer 2

您可以通过执行以下代码来获得相同值的计数

select id, texts, count(id) from table group by texts
