in SQL Developer, i want to select only one row from my table (with all attibute values) of each different value.
It’s not important what row is selected for each type, what matters is to select only one row for type.
for example i have this table:
| A | B | C | X SS G Y SB T Z SB T
Note that in my table there aren’t numbers.
The result i want is:
| A | B | C | X SS G Z SB T
But is correct also
| A | B | C | X SS G Y SB T
