Stored procedures db2存储过程合并错误

我正在尝试创建一个存储过程，该存储过程将运行从临时表到主表的合并，但是，当我尝试创建时，出现以下错误：

DB2 SQL Error: SQLCODE=-104, SQLSTATE=42601, SQLERRMC=END-OF-STATEMENT;.LAST_CHANGED_DATE
);<psm_semicolon>, DRIVER=3.69.24 [SQL State=42601, DB Errorcode=-104]

---

如何执行该语句？语句终止符有问题。我甚至无法创建要执行的存储过程。我使用SQL Workbench/J进行创建，然后从SSIS执行SP。您在SQL Workbench中设置的语句终止符是什么？在创建过程中使用“@”。我看不出在哪里可以定义语句分隔符。

CREATE PROCEDURE sp_UpdateM25
LANGUAGE SQL
BEGIN
MERGE INTO MEDILOAD.M25 M25
USING ( SELECT NDC_UPC_HR1,
        ID_NUM_FORMAT,
        REC_CODE,
        TRAN_CODE,
        OVERLOADED_AREA,
        LAST_CHANGED_DATE
        FROM MEDILOAD.M25_STAGE) M25_STAGE
on (M25.NDC_UPC_HR1 = M25_STAGE.NDC_UPC_HR1 and M25.REC_CODE = M25_STAGE.REC_CODE)
WHEN matched then
update set
M25.NDC_UPC_HR1 = M25_STAGE.NDC_UPC_HR1,
M25.ID_NUM_FORMAT = M25_STAGE.ID_NUM_FORMAT,
M25.REC_CODE = M25_STAGE.REC_CODE,
M25.TRAN_CODE = M25_STAGE.TRAN_CODE,
M25.OVERLOADED_AREA = M25_STAGE.OVERLOADED_AREA,
M25.LAST_CHANGED_DATE = M25_STAGE.LAST_CHANGED_DATE
WHEN NOT MATCHED then
INSERT

M25.TRAN_CODE,
