I have this procedure:

with error: ORA-06550: line 1, column 7:
Anyone knows how to fix this problem?
[EDIT]

Have a look at this example; read comments within the code.
I've created sample tables, just to make sure that the procedure code compiles.
SQL> create table temp (city varchar2(10), value number, mdate date);
Table created.
SQL> create table humidity (city varchar2(10), value number, mdate date);

The procedure itself:

3 is

5 l_corr number; -- statement's results
6 begin
7 select t.city, corr(t.value, h.value)
8 into l_city, l_corr --> missing INTO clause

I am creating a stored procedure in Oracle database that's resulting in error "ORA-01858: a non-numeric character was found where a numeric was expected".
My procedure is as below:
create or replace procedure testProc(
id IN VARCHAR2,
user IN VARCHAR2,
sender IN VARCHAR2
)
as
vCount number;
begin
select count(*) into vCount from table1 where id='12345'
if vCount=0
insert into table1 (id, user, sender, status) values (id, user, partner, status);
else
update table1 set status='ERR' where id='12345'
end if;
end procedure;
Error: ORA-01858: a non-numeric character was found where a numeric was expected
I tried replacing vCount as int that did not help. Also tried declaring vCount below sender IN VARCHAR2.
Can someone please tell what is correct way to use the above procedure.
Use a MERGE statement then you can do it in a single statement (rather than SELECT followed by either INSERT or UPDATE):
CREATE PROCEDURE testProc(
i_id IN table1.id%TYPE,
i_user IN table1."USER"%TYPE,
i_sender IN table1.sender%TYPE,
i_status IN table1.status%TYPE
)
AS
BEGIN
MERGE INTO table1 dst
USING (
SELECT '12345' AS id
FROM DUAL
) src
ON (src.id = dst.id)
WHEN MATCHED THEN
UPDATE SET status = 'Err'
WHEN NOT MATCHED THEN
INSERT (id, "USER", sender, status)
VALUES (i_id, i_user, i_sender, i_status);
END testProc;
/

This code can't possibly return error you specified because
procedure is invalid (mising statement terminators; column name can't be USER because it is a keyword, reserved for currently logged user)
that error code is related to date issues, while - in your code - there's nothing that looks like a date
Therefore, it is impossible to help you with error you stated. Otherwise, consider NOT naming procedure's parameters the same as column names because that leads to various problems.
Something like this would work, but it is not related to error you got.

I have a table called phonebook and it has two columns (firstName, LastName). I want to create a table of lastName index by firstName using cursor, and I wrote this code:
CREATE OR REPLACE PROCEDURE proc1 AS
TYPE tableNames IS TABLE OF VARCHAR2(20) INDEX BY VARCHAR(20);
v1 tableNames;
v_firstName PHONEBOOK.FIRSTNAME%TYPE;
v_lastName PHONEBOOK.LASTNAME%TYPE;
CURSOR c_name IS SELECT FIRSTNAME, LASTNAME FROM PHONEBOOK;
BEGIN
OPEN c_name;
LOOP
FETCH c_name INTO v_firstName, v_lastName;
EXIT WHEN c_name%NOTFOUND;
v1(v_firstName) := v_lastName;
END LOOP;
FOR idx IN v1.FIRST..v1.LAST
LOOP
DBMS_OUTPUT.PUT_LINE (v1(idx));
END LOOP;
CLOSE c_name;
END;
/
It has been successfully compiled. When I run this procedure it should print lastNames which stored in the tableNames but it gave me an error:
ORA-06502 "PL/SQL: numeric or value error"
Cause: An arithmetic, numeric, string, conversion, or constraint error
occurred. For example, this error occurs if an attempt is made to
assign the value NULL to a variable declared NOT NULL, or if an
attempt is made to assign an integer larger than 99 to a variable
declared NUMBER(2).
Action: Change the data, how it is manipulated, or how it is declared so
that values do not violate constraints.
Please help me to solve this problem
Not FOR, but WHILE. Also, I used cursor FOR loop as a source; easier to write & maintain.

I want to RUN SP2 inside SP1. The SP2 inserts several data into a table, one of those data is actual date.
So, i want that SP2 only execute if in the column date, the date is within the last 10 days.
It´s possible?
Thanks
Here's an example.
First, create a table and insert some sample rows:
SQL> create table my_tbl
2 (id number,
3 my_col date
4 );
Table created.
SQL> insert into my_tbl (id, my_col)
2 -- more than 10 days ago
3 select 1, date '2018-05-25' from dual union all
4 -- less than 10 days ago
5 select 2, date '2018-09-01' from dual;
2 rows created.
Create two procedures; SP_1 is supposed to call SP_2 if condition is met. I'm looping through both rows in the table; one row's date value is OK, another one isn't.
SQL> create or replace procedure sp_2 as
2 begin
3 dbms_output.put_line('...I am in SP_2 now');

5 if cur_r.my_col >= trunc(sysdate) - 10 then
6 dbms_output.put_line('...calling SP_2');
7 sp_2;
8 else
9 dbms_output.put_line('...date condition failed - not calling SP_2');
10 end if;
11 end loop;
12 end;
