I am fairly new and need help with this!
How can I do a SELECT
in MySQL to obtain from the following Table a result that joins all the rows in one with its columns?
Table:
ID | Name | Type1 | Type2 | Type3 | Type4 |
---|---|---|---|---|---|
1 | ABC | 123 | Null | Null | Null |
1 | ABC | Null | 456 | Null | Null |
1 | ABC | Null | Null | 789 | Null |
1 | ABC | Null | Null | Null | 900 |
Output:
ID | Name | Type1 | Type2 | Type3 | Type4 |
---|---|---|---|---|---|
1 | ABC | 123 | 456 | 789 | 900 |
I was researching and I don’t even know how to search for the function!
Thank you very much
