dashDB：在 " " 之后发现了意外的令牌"IF"。预期令牌可能包括："<call>" .SQLSTATE=42601

Question

我正在尝试将以下查询传递给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

但它给了我以下错误：

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

谁能帮我解决？
