I want to update table column from compare to other table column - oracle

I want to update column with this code
DECLARE
EMP_id EMPLOYEES.EMPLOYEE_ID1%TYPE;
EMP_REST EMPLOYEES.WEEK_REST%TYPE;
CURSOR C_EMP is
SELECT EMPLOYEE_ID1, WEEK_REST FROM EMPLOYEES
WHERE SUBSID_ACCOUNT_IDX = 103001;
BEGIN
OPEN C_EMP;
LOOP
FETCH C_EMP into EMP_id, EMP_REST ;
UPDATE PAY_IN_OUT2
SET OT = 8
WHERE
EMP_CODE = EMP_id
AND ATT_DATE IN (SELECT GAZZETED_DATE FROM GAZZETED_DAYS);
EXIT WHEN C_EMP%notfound;
END LOOP;
CLOSE C_EMP;
END;
it runs and message to me procedure complete but not updating the column where I am doing wrong please

You can do like this:
MERGE INTO PAY_IN_OUT2 e
USING EMPLOYEES h
ON (e.EMP_CODE = h.EMPLOYEE_ID1 and
SUBSID_ACCOUNT_IDX = 103001 and
ATT_DATE IN (SELECT GAZZETED_DATE FROM GAZZETED_DAYS)
)
WHEN MATCHED THEN
UPDATE SET e.OT =8 ;
or use this one:
update PAY_IN_OUT2 ea
set OT = 8
where ATT_DATE IN (SELECT GAZZETED_DATE FROM GAZZETED_DAYS)
and EMP_CODE in (SELECT EMPLOYEE_ID1 FROM EMPLOYEES
WHERE SUBSID_ACCOUNT_IDX = 103001
);
I removed the unused field WEEK_REST.

SQL statement ignored for a index nested loop join

I'm trying to build a data warehouse based on a star schema with 5 dimension tables and 1 facts table using two sets of data, MASTERDATA which holds 100 records and DATASTREAM which holds 10,000 records.
I am reading 100 records from DATASTREAM as an input into a cursor then reading the cursor record by record and then retrieving the relevant records from MASTERDATA on the index product_id as a index nested loop join. After this I am loading the new attributes from the transaction tuple inside the relevant dimension and fact tables.
However, I have a few errors. I'm just looking for help to understand why I am getting the errors I am getting. The errors at the moment are:
Error(98,6):PL/SQL:SQL Statement Ignored
Error(101,5):PL/SQL: ORA-00933: SQL command not properly ended
Error(105,8):PLS-00103:Encountered the symbol "LOOP" when expecting one of the following: if

It is an unfortunate truth that occasionally procedural processing is required. But almost all this can be done with just SQL and a tiny bit of PL/SQL extensions. In particular there is no need to "select count..." for any of your target tables, sql handles that quite easily on the INSERT statement itself. Further there is no need to loop through a cursor on a row-by-row (aka slow-by-slow) process, instead use BULK COLLECT and FORALL to handle the entire array (100 rows in this case) all with a single INSERT for each table. With it there is no need to for loop control counters, nor calculating the ID numbers to retrieve, nor the exact the number of rows (what would happen if your source table contained 10050 or 9950 rows instead of exactly 10000). As a side effect you gain considerable performance. The following shows that process:
create or replace procedure transactioninlj as

Note: The DDL for the source tables is not included in your post so I had to "invent" the definition for DATASTREAM. However, you only have 2 source inputs: DATASTREAM and MASTERDATA. Since you only select 5 columns from masterdata, every thing else must come from datastream.

How to store the number of affected records and return it as a parameter?

I have an in parameter (set = 0), to keep track of the count of entries I will be modifying. I am trying to merge data into a table called Table1, the records that have been updated in a different table (Table2) since the last time Table1 has been updated. The conditional statement will compare the Table1.LastUpdate column to the max(Modified_date) column of Table2 and only insert entries where the table1.last_update column is greater than the table2.max(modified_date) column. Then I will need to store this number and return it as an out parameter. What I have is follows:
create or replace procedure test_proc (rUpdated_Row_Count IN NUMBER, rUpdated_Row_Count_2 OUT NUMBER) is
CURSOR c1 is
select max(modified_date) as max_modified_date
from table1;
l_var c1%ROWTYPE;
-----------
CURSOR c2 is
select table2_id
, last_update
from table2;
k_var c2%ROWTYPE;
BEGIN
LOOP
Open c1;
Fetch c1 into l_var;
Open c2;
Fetch c2 into k_var;
EXIT WHEN c1%NOTFOUND;
IF k_var.last_update > l_var.max_modified_date THEN
Insert into table2(table2_id, last_update)
values(null, k_var.last_update);
commit;
rUpdated_Row_Count_2 := rUpdated_Row_Count + 1;
END IF;
END LOOP;
Close c1;
Close c2;
END test_proc;
Thanks in advance!
Modified my code (after doing further research):
create or replace procedure test_proc (rUpdated_Row_Count IN NUMBER, rUpdated_Row_Count_2 OUT NUMBER) is
CURSOR c1 is
select max(modified_date) as max_modified_date
from table1;
l_var c1%ROWTYPE;
-----------
CURSOR c2 is
select table2_id
, last_update
from table2;
k_var c2%ROWTYPE;
BEGIN
Open c1;
Open c2;
LOOP
Fetch c1 into l_var;
Fetch c2 into k_var;
EXIT WHEN c2%NOTFOUND;
IF k_var.last_update > l_var.max_modified_date THEN
Insert into table2(table2_id, last_update)
values(null, k_var.last_update);
commit;
rUpdated_Row_Count_2 := rUpdated_Row_Count + 1;
END IF;
END LOOP;
Close c1;
Close c2;
END test_proc;
Reproducable data / Code is below:
Create table1
(
table1_id number,
modified_date date
);
Create table2
(
table2_id number,
last_update date
);
insert into table1(table1_id, modified_date) values(1, sysdate);
insert into table1(table1_id, modified_date) values(2, sysdate);
insert into table1(table1_id, modified_date) values(3, sysdate -1);
insert into table2(table2_id, last_update) values(1, sysdate + 1);
insert into table2(table2_id, last_update) values(2, sysdate + 2);
Not quite sure what the "IN" parameter is for. Also not quite sure about the overall rationale. However, here's how I'd write a first version of your procedure:
create or replace procedure test_proc2 (
rUpdated_Row_Count IN NUMBER
, rUpdated_Row_Count_2 IN OUT NUMBER )
is
max_modified_date date ;
begin
select max( modified_date ) into max_modified_date from table1 ;
for rec_ in (
select table2_id, last_update
from table2
) loop
if rec_.last_update > max_modified_date then
insert into table2( table2_id, last_update )
values( null, rec_.last_update ) ;
rUpdated_Row_Count_2 := rUpdated_Row_Count_2 + 1 ;
end if ;
end loop;
end ;
/
Using your test tables (your DDL code should be: CREATE TABLE table1 ... by the way), we can use the following anonymous block for executing the procedure.
-- not sure what the "IN" parameter is used for
declare
rowcount_in number := 0 ; -- not needed
rowcount_out number := 0 ;
begin
test_proc2( rowcount_in, rowcount_out ) ;
dbms_output.put_line( 'updated rows: ' || rowcount_out ) ;
end;
/
updated rows: 2
After executing the anonymous block the tables contain ...
SQL> select * from table1 ;
TABLE1_ID MODIFIED_DATE
1 15-MAY-18
2 15-MAY-18
3 14-MAY-18
SQL> select * from table2 ;
TABLE2_ID LAST_UPDATE
1 16-MAY-18
2 17-MAY-18
NULL 16-MAY-18
NULL 17-MAY-18
Many people will tell you that you should use BULK operations (BULK COLLECT, FORALL etc) whenever possible. Does all that help you?

Check if Exists PLS-00405: subquery not allowed in this context

I have cursor it selects from TableA then Fetch Loop that inserts into TableB.
I want to check if the value already exists in the TableB.
If it exists then I want to skip the insert.
create or replace
PROCEDURE DAILY_RPT (
v_start IN DATE,
v_end IN DATE)
IS
ao_out_no out_pair.out_no%type;
cursor get is
SELECT ao_out_no from tableA;
BEGIN
open get;
LOOP
fetch get into ao_out_no;
EXIT WHEN get%NOTFOUND;
if (ao_out_no = (select out_no from TableA where out_no = ao_out_no) THEN
--DO NOTHING
else
INSERT INTO TABLEB(OUT_NO) VALUES (ao_out_no);
end if;
END LOOP;
close get;
END;
I used IF CONDITION however, I used variable into if condition & I am getting below.
PLS-00405: subquery not allowed in this context
if (ao_out_no = (select out_no from TableA where out_no = ao_out_no) THEN
You don't need cursor or PL/SQL at all:
INSERT INTO TABLEB(OUT_NO)
SELECT ao_out_no
FROM tableA ta
WHERE ... -- filtering rows
AND NOT EXISTS (SELECT * From TableB tb WHERE tb.OUT_NO = ta.ao_out_no);
Use the following :
for i in (
select out_no from TableA where out_no
)
loop
if i.out_no = ao_out_no
then
-- DO NOTHING
else
...
or
create a new variable named x, and then assign a value to it by
select out_no into x from TableA where out_no = ao_out_no;
and check returning value for x.
With corrected syntax, it would be something like this:
create or replace procedure daily_rpt
( v_start in date
, v_end in date )
as
begin
for r in (
select ao_out_no, 0 as exists_check
from tablea
)
loop
select count(*) into exists_check
from tablea
where out_no = r.ao_out_no
and rownum = 1;
if r.exists_check > 0 then
--DO NOTHING
else
insert into tableb (out_no) values (r.ao_out_no);
end if;
end loop;
end;
However, it's inefficient to query all of the rows and then do an additional lookup for each row to decide whether you want to use it, as SQL can do that kind of thing for you. So version 2 might be something like:
create or replace procedure daily_rpt
( v_start in date
, v_end in date )
as
begin
for r in (
select ao_out_no
from tablea
where not exists
( select count(*)
from tablea
where out_no = r.ao_out_no
and rownum = 1 )
)
loop
insert into tableb (out_no) values (r.ao_out_no);
end loop;
end;
at which point you might replace the whole loop with an insert ... where not exists (...) statement.

ORA-01007: variable not in select list-1007

I have the table below:

While executing I got the following error:
SQL> exec dyn_sql_sp;
ORA-01007: variable not in select list-1007
In your procedure the below code is going to create problem. As far i understand you are trying to select columns of table employee depending on 'Y' flag from table req1_tb.
Problematic Part:
for i in col_c
loop
EXECUTE IMMEDIATE 'SELECT ' || cols || ' FROM employees WHERE employee_id = :1'
--***The INTO clause is problematic here. Since the you select list is not*** having all the columns same as your cursor variable.
INTO emp
USING i.employee_id;
end loop;
Now, you are not trying the same logic while declaring a variable to hold the data returned from those selected columns in Execute Immediate statement.
For that the variable declaration should also be dynamic. So you declaration
emp employees%rowtype;
should be such that it also have all the selected columns satisfying condition flag 'Y'. You cannot insert few columns selected from your select statement to a cursor variable having all the columns.

picking 1 column from 2 tables and comparing them

In my Oracle database there are two tables which are TEMP_HR and PAY_SLIP_APR_16. Both of them have a common column named EMP_ID. TEMP_HR has over 10,000 records and PAY_SLIP_APR_16 has around 6,000 records. I want to know how many EMP_ID of PAY_SLIP_APR_16 is matched with TEMP_HR. If any ID doesn't match then print it. And here is my simple approach but I think its a very bad approach. So any faster method?
DECLARE
INPUT_EMP_NO VARCHAR2(13 BYTE);
INPUT_EMP_ID VARCHAR2(13 BYTE);
ROW_COUNT_1 NUMBER(6,0);
ROW_COUNT_2 NUMBER(6,0);
MATCHED_ID NUMBER;
UNMATCHED_ID NUMBER;
BEGIN
ROW_COUNT_1:=0;
ROW_COUNT_2:=0;
MATCHED_ID:=0;
UNMATCHED_ID:=0;
SELECT COUNT(*) INTO ROW_COUNT_1 FROM PAY_SLIP_APR_16;
SELECT COUNT(*) INTO ROW_COUNT_2 FROM TEMP_HR;
FOR A IN 1..ROW_COUNT_1 LOOP
BEGIN
SELECT EMP_ID INTO INPUT_EMP_ID FROM (SELECT EMP_ID, ROWNUM AS RN FROM PAY_SLIP_APR_16) WHERE RN=A;
FOR B IN 1..ROW_COUNT_2 LOOP
SELECT EMP_NO INTO INPUT_EMP_NO FROM (SELECT EMP_NO, ROWNUM AS RON FROM TEMP_HR) WHERE RON=B;
IF(INPUT_EMP_ID=INPUT_EMP_NO)THEN
MATCHED_ID:=MATCHED_ID+1;
EXIT;
ELSE
CONTINUE;
END IF;
END LOOP;
UNMATCHED_ID:=UNMATCHED_ID+1;
DBMS_OUTPUT.PUT_LINE(INPUT_EMP_ID);
EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE(INPUT_EMP_ID||' -> '||SQLERRM);
END;
END LOOP;
DBMS_OUTPUT.PUT_LINE('MATCHED -> '||MATCHED_ID);
DBMS_OUTPUT.PUT_LINE('UNMATCHED -> '||UNMATCHED_ID);
END;
Use an outer join filtering for missed joins:
select p.*
from PAY_SLIP_APR_16 p
left join TEMP_HR t on t.EMP_ID = p.EMP_ID
where t.EMP_ID is null
An index on TEMP_HR(EMP_ID) will make this query fly.
You should use SQL sets!
To check which EMP_ID isn't in TEMP_HR you may try this:
select EMP_ID FROM PAY_SLIP_APR_16
where EMP_ID not in (select EMP_NO from TEMP_HR);
Then the other way around:
select EMP_NO FROM TEMP_HR
where EMP_NO not in (select EMP_ID from PAY_SLIP_APR_16);
