存储过程中的问题：db2

我已经在db2中编写了以下存储过程。存储过程中的问题：db2

CREATE or REPLACE PROCEDURE RTIMD.IALERT_PROC (IN usr_name VARCHAR(20) DEFAULT '', IN IN_RTIM_ID VARCHAR(25) default '', IN api_method VARCHAR(25) DEFAULT '', IN params VARCHAR(500) default '', IN application_name VARCHAR(20) default '', OUT TICKT_ID VARCHAR(20), OUT RTIMID_VAR VARCHAR(25)) 
LANGUAGE SQL 
BEGIN 

DECLARE RTIM_ID_OUT VARCHAR(25); 

IF api_method = 'getIncident' THEN 
    SET TICKT_ID = EXECUTE IMMEDIATE ('SELECT DISTINCT TICKET_ID FROM RTIMD.V3_TICKET_LOG WHERE RTIM_ID = IN_RTIM_ID'); 
    SET RTIM_ID_OUT = IN_RTIM_ID; 
ELSEIF api_method = 'createIncident' THEN 
    SET RTIMID_VAR = EXECUTE IMMEDIATE ("select 'RTIM_' concat usr_name concat varchar(bigint(days(current date) - days('1970-01-01'))*bigint(86400) + midnight_seconds(current_timestamp - current_timezone)) concat '_' concat varchar(SMALLINT (RAND() *10000 + 1)) from SYSIBM.SYSDUMMY1"); 
    SET RTIM_ID_OUT = RTIMID_VAR; 
ELSEIF api_method = 'closeIncident' THEN 
    SET RTIM_ID_OUT = IN_RTIM_ID; 
END IF; 

INSERT INTO RTIMD.V3_TICKET_LOG(RTIM_ID, STATE, API_METHOD, API_MESSAGE, TICKET_TYPE, IMPACT_ROW_ID, TICKET_ID, PARAMS, REMOTE_USER, CREATED, UPDATED, DB_STATE, CPS_STATE, APPLICATION, PRB_OWNER, SN_INSTANCE) VALUES (RTIM_ID_OUT, 0, api_method, '', 'Incident', 0, '', params, usr_name, CURRENT TIMESTAMP, TIMESTAMP, 0, 0, application_name, 'self', ''); 

END

执行存储的proc时，出现以下错误消息。。

DB21034E The command was processed as an SQL statement because it was not a 
valid Command Line Processor command. During SQL processing it returned: 
SQL0104N An unexpected token "IMMEDIATE" was found following "SET 
TICKT_ID=EXECUTE". Expected tokens may include: "IN". LINE NUMBER=1. 
SQLSTATE=42601

出了什么错在这里，我已经够冲浪，但没有答案:( 可能有一些语法错误请指引我

TIA
