You can select unique records in MariaDB using the `DISTINCT` keyword. The `DISTINCT` keyword removes duplicate rows from the result set.
Here is an example:
```
SELECT DISTINCT column_name FROM table_name;
```
In this SQL query, replace `column_name` with the name of the column where you want to select unique entries, and replace `table_name` with the name of your table.
If you want to select unique combinations across multiple columns, include all the column names, separated by commas. Here is an example:
```
SELECT DISTINCT column_name1, column_name2 FROM table_name;
```
This will return a result set with unique combinations of values from `column_name1` and `column_name2`.
