Answer 1

Add GROUP BY to field you want to check for duplicates your query may look like

SELECT field1, field2, field3, ......   FROM table GROUP BY field1

field1 will be checked to exclude duplicate records

or you may query like

SELECT *  FROM table GROUP BY field1

duplicate records of field1 are excluded from SELECT
