Why no results when executing PLSQL procedure? - sql

Question

I have written the following PLSQL procedure:
create or replace procedure lrt_bericht (current_date in VARCHAR2, last_date in VARCHAR2) as
calendar_week VARCHAR2(10);
BEGIN
calendar_week := EXTRACT(YEAR FROM sysdate)||'_'||to_char(to_date(current_date,'DD.MM.YYYY'),'IW');
delete from astrid_liste_history
where link_to_uts is null;
insert into astrid_liste_bericht
(Link_to_UTS,Incident_Number,CI_Plus,Site_ID,Anzahl_CI_ID,Anzahl_Zellen,Status_690,Service_Affecting,Incident_Work_Info_Notes,Target_Date,Incident_Work_Info_Summary,Assigned_Group,Submit_Date_max,Last_Modified_Day,Region_CI_Plus,WEATHERMAP_LONGTERM,Incident_Summary,Reported_Date,Status,Company,Incident_Notes,Supercluster,CI_Plus_Cons_Top65,CI_Plus_Cons_Region,CI_Plus_Cons_Year,Last_LRI_Update,Link_to_ATEA,Bereich_Gruppe,Connect_Prio,Connect_Pop_Rank,Categorization_Tier_1,Categorization_Tier_2,Categorization_Tier_3,Date_Import,Time_Import)
select *
from astrid_liste_history
where astrid_liste_history.date_import = current_date;
update astrid_liste_bericht
set Closed_In_CW = calendar_week
where
incident_number in
(select incident_number from astrid_liste_bericht where date_import = last_date
and INCIDENT_WORK_INFO_SUMMARY like '%Volker%'
minus
select incident_number from astrid_liste_bericht where date_import = current_date)
;
update astrid_liste_bericht
set Closed_In_CW = NULL
where date_import not in (last_date)
and Closed_In_CW = calendar_week;
update astrid_liste_bericht
set ADPW = 'Yes'
where
closed_in_cw = calendar_week
and upper(INCIDENT_SUMMARY) like '%ADPW%';
update astrid_liste_bericht
set ADPW = 'No'
where
closed_in_cw = calendar_week
and upper(INCIDENT_SUMMARY) not like '%ADPW%';
COMMIT;
END lrt_bericht;
It compiles sucessfully but after trying to execute it:
begin
lrt_bericht('10.11.2019','03.11.2019');
end;
there is no data written into the astrid_liste_bericht table.
However, if I execute manually every step in the procedure, at the end I can see the data being added/updated in the astrid_liste_bericht table.
Do you have any idea why this happens and what should I do in oder to make the data be updated in the astrid_liste_bericht table via the procedure?

This looks to me like an issue with date mismatch. What is the column type of astrid_liste_history.date_import.
Can you run this query and confirm if data comes back from sql prompt
select *
from astrid_liste_history
where astrid_liste_history.date_import = current_date ;
Replace this current_date with whatever date you are passing to Proc.
Adding test script
CREATE OR REPLACE PROCEDURE temp_proc
(
current_date1 IN VARCHAR2
,last_date IN VARCHAR2
) AS
calendar_week VARCHAR2(10);
BEGIN
calendar_week := extract(YEAR FROM SYSDATE) || '_' ||
to_char(to_date(current_date, 'DD.MM.YYYY'), 'IW');
INSERT INTO temp
(temp1)
SELECT 1 FROM temp2 WHERE temp2.date_import = current_date1;
COMMIT;
END temp_proc;
/
CREATE TABLE temp(temp1 VARCHAR2(100));
/
CREATE TABLE temp2(date_import VARCHAR2(100));
/
INSERT INTO temp2 VALUES('10.11.2019')
SELECT 1 FROM temp2 WHERE temp2.date_import = '10.11.2019';
SET serveroutput ON
BEGIN
temp_proc('10.11.2019', NULL);
END;
/
select *
from temp;
