just wanted to ask how to resolve the error above. I am trying to create a function that will generate how many product were ordered per product category.
Here is my function. The function compiled but when I try to run the declare part that's where I get the error.
DECLARE
CURSOR this_category IS
SELECT category_id
from comm_order_details;
prod_ordered comm_order_details.quantity%type;
BEGIN
For rec_category IN this_category
LOOP
prod_ordered := prod_ordered_func(rec_category.category_id);
DBMS_OUTPUT.PUT_LINE('Category ID:' || rec_category.category_id||'-' || 'Total Order:' || prod_ordered );
END LOOP;
END;

Using my anonymous block I have written below, the bind variable is giving me the error: I've pasted a picture of the table below.
edit: ETHI1022 is the input I'm giving for the CORID
v_corid CHAR(8) := ETHI1022;

I realize my inner join is most likely messed up like no other. I'm trying to learn this stuff and am having a very hard time learning how taking values from the select statement and placing them into the variables in the declare section works.

[Table used]
Instead of ETHI1022 it should be 'ETHI1022'. Your inner join is fine. From where you are getting value of corid. Make it of type varchar/string or something like that.
Or you might try v_corid CHAR(8) := ''''||&corid||'''';

When i run this set of procedures i get an error in the compiler stating:
Error(1,13): PLS-00215: String length constraints must be in range (1 .. 32767)
Error(2,14): PLS-00215: String length constraints must be in range (1 .. 32767)
I have tried adding constraints to the code that calls the main Procedure:
CREATE OR REPLACE PROCEDURE ADD_LOCATION_VIASQLDEV AS
Dis_Msg VARCHAR2(40);
ploccode VARCHAR2(5);
pminqty NUMBER(2);
pmaxqty NUMBER(2);
BEGIN
dbms_output.put_line('--------------------------------------------------');
dbms_output.put_line('Adding location LocCode: ' || ploccode || ' MinQty: ' || pminqty || 'MaxQty' || pmaxqty);
ADD_LOCATION_TO_DB(ploccode, pminqty, pmaxqty);
dbms_output.put_line(Dis_Msg);
END;
/
Adding these constrains does remove the errors with the compiler however i still revive errors when executing this testing code:
Error starting at line : 48 in command -

Can some one please tell me what i'm doing wrong.
Apologies if this is to much information or my formating is wrong.
You are confused between the declaration section and arguments sections of the procedure.
Your first error is due to the fact that you placed your supposedly arguments in the declaration section. then when you tried to add length to it, it compiled, but you left the procedure without arguments. then you run it with four arguments which caused the error since the procedure is created accepting no arguments.
create or replace procedure_name(
parameter1 datatype, --arguments section
parameter2 datatype
) AS
/*declaration section*/
variable1 datatype(length);
variable2 datatype(length);
BEGIN
/*your code here*/
END;
try this revise script
CREATE OR REPLACE PROCEDURE ADD_LOCATION_VIASQLDEV (Dis_Msg VARCHAR2,
ploccode VARCHAR2,
pminqty NUMBER,
pmaxqty NUMBER ) AS
BEGIN
dbms_output.put_line('--------------------------------------------------');
dbms_output.put_line('Adding location LocCode: ' || ploccode || ' MinQty: ' || pminqty || 'MaxQty' || pmaxqty);
ADD_LOCATION_TO_DB(ploccode, pminqty, pmaxqty);
dbms_output.put_line(Dis_Msg);
END;
In your first set of errors, you declared the function as using a VARCHAR2 variable, but didn't state a length in brackets after it. State a length
In your second set of errors you called the function add_location_viasqldev which takes 0 arguments, but you provided 3. Provide another argument or call a different function
Also, you can make your if/else a bit neater by doing:
IF test
ELSIF test
ELSIF test
ELSE
END IF;
I'm trying to use the sum function with a package function but running into an "invalid identifier" bug. Here's some example code with the error causing function commented
create or replace type numType as object
(
myNum number
)
;
/
create or replace type numTypes is table of numType;
/
create or replace package testNumberPackage as
function ReturnNum(in_numType numType) return number;
end;
/
create or replace package body testNumberPackage as
function ReturnNum(in_numType numType) return number is
begin
return in_numType.myNum;
end;
end;
/
declare l_numTypes numTypes;
l_count number;
begin
l_numTypes := numTypes();
for i in 1 .. 100 loop
l_numTypes.extend(1);
l_numTypes(l_numTypes.last) := numType(i);
end loop;
select sum(n.myNum) into l_count from table(l_numTypes) n;
select sum(testNumberPackage.ReturnNum(n)) into l_count from table(l_numTypes) n; --causes the error
dbms_output.put_line(l_count);
end;
/
The exact error for this code is
ORA-06550: line 11, column 42
PL/SQL: ORA-00904: "N": invalid identifier
ORA-6550: line 11, column 3:
PL/SQL: SQL Statement ignored
Thanks for any help.
The first issue is that you can't pass a table into a parameter by using its alias. It doesn't even make sense to try doing that.
The next issue is how to get the column mynum that is returned from the table(l_numTypes) into the correct format to pass into testNumberPackage.ReturnNum, since it's of NUMBER datatype, and the function is expecting a numtype parameter.
To do that, you need to pass in an object with that column, like so: numtype(n.mynum).
The following works for me:
declare
l_numTypes numTypes;
l_count number;
begin
l_numTypes := numTypes();
for i in 1 .. 100 loop
l_numTypes.extend(1);
l_numTypes(l_numTypes.last) := numType(i);
end loop;
select sum(n.myNum) into l_count from table(l_numTypes) n;
select sum(testNumberPackage.ReturnNum(numtype(n.mynum))) into l_count from table(l_numTypes) n; --causes the error
dbms_output.put_line(l_count);
end;

I am having an issue doing a plsql command. The idea is to show the courier, location, and yes or not if it is over 20.
DECLARE
yesnobool VARCHAR(3);
CURSOR orders_list IS
SELECT shipping.ship_courier,
shipping.weightpership,
shipping.shipping#,
purchaseorder.shipping#,
storelocation.location#,
STORELOCATION.LOC_CITY,
purchaseorder.location#
FROM shipping,
purchaseorder,
storelocation
WHERE purchaseorder.shipping# = shipping.shipping#
and storelocation.location# = purchaseorder.location#;
BEGIN
dbms_output.Put_line('Courier || Location || Too Heavy for 1 person lift?');
dbms_output.Put_line('------ -------- -----------------------------------');
FOR an_order IN orders_list LOOP
IF SHIPPING.WEIGHTPERSHIP > 20 THEN
yesnobool := 'YES';
ELSE
yesnobool := 'NO';
END IF;
dbms_output.Put_line(Rpad(an_order.ship_courier, 6) || ' ' ||
Rpad(an_order.loc_city, 8) || ' ' ||
Rpad(yesnobool, 19));
END LOOP;
END;
The Error message i am getting is:

Im not very good with plsql so i dont really know how to pin down the issue. Thank you in advance for any and all advice.
Columns shipping# and location# are duplicated in your select field list.
shipping.shipping#
purchaseorder.shipping#
storelocation.location#,
purchaseorder.location#
The cursor is unable to distinguish which shipping or location its supposed to use.
The solution is to alias the fields. Something like this:
shipping.shipping# as shipping,
purchaseorder.shipping# as poshipping
And:
storelocation.location# as storeLocation,
purchaseorder.location# as poLocation
