GoldenGate @STRCAT亂碼

今天在測試GoldeGate Oracle到MSSQL的資料同步時，發現GoldenGate的對列的計算會出現亂碼：

GGSCI (chenyj-WorkPC) 37> view param msrep1
REPLICAT MSREP1
setenv(NLS_LANG=AMERICAN_AMERICA.AL32UTF8)
targetdb ggs_nc
GETTRUNCATES
APPLYNOOPUPDATES
SOURCEDEFS dirdef/source.def
--MAP scott.customer, TARGET dbo.customer;
map scott.myemps, target dbo.myemps,
COLMAP (USEDEFAULTS,
WAGES = @COMPUTE(SALARY * 12)
FULL_NAME = @STRCAT(LAST_NAME,",",FIRST_NAME));


first_name與last_name都可以正確的從oracle複製到MSSQL,但是當涉及到字串的拼接時，結果就出現了問題。可以檢視圖片

可以採用觸發器的方式解決問題
附MSSQL觸發器：

AS 
  declare @first_name varchar(200), @last_name varchar(200), @id numeric;
BEGIN


update myemps set full_name = inserted.first_name + inserted.last_name from inserted where inserted.id = myemps.id

    -- Insert statements for trigger here

END
GO
