Single value data to multiple values of data in database relation
- by Sofiane Merah
I have such a hard time picturing this. I just don't have the brain to do it.
I have a table called reports.
---------------------------------------------
| report_id   | set_of_bads | field1 | field2 |
---------------------------------------------
| 123         | set1        | qwe    | qwe    |
---------------------------------------------
| 321         | 123112      | ewq    | ewq    |
---------------------------------------------
I have another table called bads. This table contains a list of bad data.
-------------------------------------
| bad_id    | set_it_belongs_to | field2 | field3  |
-------------------------------------
| 1         | set1              | qwe    | qwe     |
-------------------------------------
| 2         | set1              | qee    | tte     |
-------------------------------------
| 3         | set1              | q44w   | 3qwe    |
-------------------------------------
| 4         | 234               | qoow   | 3qwe    |
-------------------------------------
Now I have set the first field of every table as the primary key. My question is, how do I connect the field set_of_bads to set_it_belongs_to in the bads table. This way if I want to get the entire set of data that is set1 by calling on the reports table I can do it.
Example: hey reports table.. bring up the row that has the report_id 123. Okay thank you.. Now get all the rows from bads that has the set_of_bads value from the row with the report_id 123. Thanks.
