dashDB：在“”后面找到一个意外的标记“IF”。预期的令牌可能包括：“<call>”。 SQLSTATE = 42601

Question

我试图通过以下查询来dashdb：

IF (NOT EXISTS (SELECT * FROM TEST_CONFIGURATION WHERE DEVICEID = 'OZ_POLLUDRON_010')) 
BEGIN 
INSERT INTO TEST_CONFIGURATION (DEVICEID, DEVICETYPE, SERIAL, TYPE, MACID, CONFIG, INIT) VALUES('OZ_POLLUDRON_010', 'POLLUDRON_PRO', '9428424248', 0, '200050000b51343334363138', '[object Object]', '[object Object]') 
END 

ELSE 
BEGIN 
UPDATE TEST_CONFIGURATION SET DEVICEID = 'OZ_POLLUDRON_010', DEVICETYPE = 'POLLUDRON_PRO', SERIAL = '9428424248', TYPE = 0, MACID = '200050000b51343334363138', CONFIG = '[object Object]', INIT = '[object Object]' WHERE DEVICEID = 'OZ_POLLUDRON_010' END 

但它给我以下错误：

database/sql/driver: [IBM][CLI Driver][DB2/LINUXX8664] SQL0104N An unexpected token "IF" was found following " ". Expected tokens may include: "<call>". SQLSTATE=42601 

任何人都可以请帮我呢？

考虑使用MERGE语句来实现一个upsert动作（如果不存在其他更新，则插入）。示例位于DB2示例目录和DB2知识中心中。
