在同一个表中组合两个表的结果

I have two tables :

我有两张桌子：

TMP_Turnover

Year Code   | CODE_DEVISE   | CODE_AFFILIATE|   Period  |Turnover

TMP_Outstanding

Year Code   |CODE_DEVISE    |CODE_AFFILIATE |Frequency  |Period |Outstanding

How to comine the results of the tables in one table Main

如何在一个表Main中查看表的结果

 Year Code  |CODE_DEVISE    |CODE_AFFILIATE |Frequency  |Period |Outstanding|Turnover

I tried using union but it dosen't return the best results, I'm a newbie with SQL SERVER.

    TT.CODE_AFFILIATE,
    TO.Frequency,
    TT.Period,
    TO.Outstanding,

LEFT JOIN TMP_Outstanding TO ON TT.YearCode=TO.YearCode 
    AND TT.CODE_DEVISE=TO.CODE_DEVISE 
    AND TT.CODE_AFFILIATE=TO.CODE_AFFILIATE
    AND TT.Period=TO.Period
