SQL UNION is query that allows you to select related information from 2 tables, this is combine 2 SELECT statement into 1 and display it out.
UNION will only return DISTINCT value only. Which means will eliminate duplicate records that returned.
There are some condition that need to meet when using the UNION statement.
The syntax is as follows:
SELECT [COLUMN NAME 1], [COLUMN NAME 2],… FROM [TABLE NAME 1]
We have 2 table name GamesScores, GameScores_new.
SQL statement :
SELECT PlayerName FROM GameScores
