How to insert CodeValueTo on Table TradeCode where codevaluefrom equal to codevalue on table tradecode and not exist on Tradecode table ?

I need to insert CodeValueTo into temp table #tradecode where CodeValueFrom exist on temp table #tradecode

I work on SQL server 2012 and below is my sample data

 

create table #MappingCodeValue
 (
 id int identity (1,1),
  CodeTypeFrom  nvarchar(50),
 CodeValueFrom  nvarchar(50),
 CodeTypeTo  nvarchar(50),
 CodeValueTo  nvarchar(50)
 )
 INSERT INTO #MappingCodeValue
 (CodeTypeFrom,CodeValueFrom,CodeTypeTo,CodeValueTo)
 VALUES
 ('ECCS-US','AB123-US','ECCS-URB','AB123-URB'),
 ('ECCS-US','AB555-US','ECCS-URB','AB555-URB'),
 ('ECCS-US','AB666-US','ECCS-URB','AB666-URB'),
 ('ECCS-US','AB756-US','ECCS-URB','AB778-URB')


 CREATE TABLE #TradeCode
 (
 TradeCodeId int identity(1,1),
 PartId  int,
 Partlevel int,
 CodeType  nvarchar(50),
 CodeValue nvarchar(50)
 )
 insert into #TradeCode(PartId,Partlevel,CodeType,CodeValue)VALUES
 (1222,1,'ECCS-US','AB123-US'),
 (1255,1,'ECCS-US','AB555-US'),
 (1444,1,'ECCS-US','AB666-US'),
 (1931,1,'ECCS-US','AB756-US')
Expected  data inserted to #tradeCode temp table as below :

(1222,1,'ECCS-US','AB123-URB'),
 (1255,1,'ECCS-US','AB555-URB'),
 (1444,1,'ECCS-US','AB666-URB'),
 (1931,1,'ECCS-US','AB778-URB')

 

I check if value of codevaluefrom on temp table #mappingcodevalue exist on temp table #tradecode field codevalue

then get equal value from codevalueTo then add it to temp table #tradecode with code type

to summarize what i need is to check #tradecode temp table field codevalue if it have same value on codevaluefrom on temp table

#mappingcodevalue then get codevalueto and add it as new row with equation value codevalueto in case of not exist on table #tradecode.
