Hello Experts,
I have a script to do merging if the two tables' information are match and if not then do the update. I don't know what I did wrong, would you please help out?
create or replace FUNCTION "ECISDRDM"."PR_MIG_STG_APPL_CDIM" (v_Ret OUT bigint )
as $$
declare
v_ErrorCode bigint;
v_ErrorMsg varchar(512);
v_Module varchar(32) = 'PR_MIG_STG_APPL_CDIM';
begin
----
-- MERGING: STG_APPLICATION_CDIM into APPLICATION_CDIM
----
MERGE INTO "ECISDRDM"."APPLICATION_CDIM" prod
USING (
SELECT Receipt_Number,application_id, init_frm_id, frm_typ_id, init_src_sys_id, init_svc_ctr_id,
crtd_user_id, sbmtd_dt_id, mig_filename, mig_modified_dt
FROM stg_application_cdim
ORDER by mig_filename ) stg
ON ( prod.receipt_number = stg.receipt_number )
WHEN MATCHED THEN UPDATE SET
prod.application_id = stg.application_id,
prod.init_frm_id = stg.init_frm_id,
prod.frm_typ_id = stg.frm_typ_id,
prod.init_src_sys_id = stg.init_src_sys_id,
prod.init_svc_ctr_id = stg.init_svc_ctr_id,
prod.crtd_user_id = stg.crtd_user_id,
prod.sbmtd_dt_id = stg.sbmtd_dt_id,
prod.mig_filename = stg.mig_filename,
prod.mig_modified_dt = current_timestamp
WHEN NOT MATCHED THEN INSERT
(prod.Receipt_Number,
prod.application_id,
prod.init_frm_id,
prod.frm_typ_id,
prod.init_src_sys_id,
prod.init_svc_ctr_id,
prod.crtd_user_id,
prod.sbmtd_dt_id,
prod.mig_filename
) SELECT (
stg.Receipt_Number,
stg.application_id,
stg.init_frm_id,
stg.frm_typ_id,
stg.init_src_sys_id,
stg.init_svc_ctr_id,
stg.crtd_user_id,
stg.sbmtd_dt_id,
stg.mig_filename
)

ERROR: "application_cdim" is not a known variable

even I take schema_name, ECISDRDRM out, I still get an error:
ERROR: "application_cdim" is not a known variable
LINE 13: MERGE INTO APPLICATION_CDIM prod

thank you for your help.
