What is wrong with the following statement:
DECLARE
int_exists INTEGER;
BEGIN
SELECT COUNT(ItemKey)
INTO int_exists
FROM BIR_TabsForDashboard
WHERE ItemKey = 'Position';
IF( int_exists = 0 ) THEN --doesnt exist
EXECUTE IMMEDIATE 'ALTER TABLE BIR_TabsForDashboard ADD Position int NULL';
END IF;
END;
I get this report error:
ORA-06550: line 7, column 9:
PL/SQL: ORA-00904: "ITEMKEY": invalid identifier
ORA-06550: line 4, column 3:
PL/SQL: SQL Statement ignored
06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.
What could be wrong? It seems to work when I use it on another table but for some reason it comes up with this error when I do it to this specific table?
The table BIR_TabsForDashboard does not have a column named ItemKey.
Make sure the procedure which you are using is should properly declared in the place which you are using it. For an example if it is under an another user and in an another package then it should be in that same order. The username, package and procedure name.

I need to loop through some values inside the plsql code.
so trying to create a collection of records .
getting error as mentioned below.
Please help me to resolve
-- please see the code below
declare
type tab_name is record (t_name varchar2(30),col_name varchar2(30));
type tab_list is table of tab_name;
table_names tab_list:=tab_list(tab_name('ABC','abc'),tab_name('XYZ','xyz'));
begin
for i in table_names.first..table_names.last loop
dbms_output.put_line(table_names(i).t_name||'-'||table_names(i).col_name);
end loop;
end;

Record type's name is not its initializer.
In fact, there is no initialization-like function for record types at all in oracle:
Documentation
Note that values are assigned separately to each field of a record in
Example 5-47. You cannot assign a list of values to a record using an
assignment statement. There is no constructor-like notation for
records.
You have to create each object separately and then create collection with them:
declare
type tab_name is record (t_name varchar2(30),col_name varchar2(30));
type tab_list is table of tab_name;
name_1 tab_name;
table_names tab_list;
begin
name_1.t_name := 'ABC';
name_1.col_name := 'abc';
table_names := tab_list();
table_names.extend;
table_names(table_names.last) := name_1;
name_1.t_name := 'XYZ';
name_1.col_name := 'xyz';
table_names.extend;
table_names(table_names.last) := name_1;
for i in table_names.first..table_names.last
loop
dbms_output.put_line(table_names(i).t_name||'-'||table_names(i).col_name);
end loop;
end;
Collections DO have initializers. However, in your case you have a collection of record types, so you would have to have your records pre-created to make use of it.
I was trying to work on nested record example.
Please have a look at declaration section.
DECLARE
TYPE r_emp IS RECORD (
name VARCHAR2(50),
dept_rec departments%ROWTYPE
);
r_emp_row r_emp;

INTO r_emp_row

WHERE emp.department_id = dept.department_id
AND emp.employee_id = 100;
DBMS_OUTPUT.PUT_LINE('Name:'||r_emp_row.name);
DBMS_OUTPUT.PUT_LINE('Department ID:'||r_emp_row.dept_rec.department_id);
DBMS_OUTPUT.PUT_LINE('Department Name:'||r_emp_row.dept_rec.department_name);
EXCEPTION
when others then
null;
END;
I am trying to run above block but getting error as below:

Help appreciated.
Your record type r_emp is a composite of one scalar attribute and one record, so you will need to reflect that in the select into. Something like:
select emp.first_name||' '||emp.last_name, dept.*
into r_emp_row.name, r_emp_row.deptrec.dempno, r_emp_row.deptrec.dname ...
btw unrelated to the problem, when others then null is a famously dangerous construction:
What is bad in "When Others Then Null" in PL/SQL?
http://www.orafaq.com/wiki/WHEN_OTHERS
http://tkyte.blogspot.co.uk/2008/06/when-others-then-null-redux.html
What if there is no employee 100? Fine, it does nothing - perhaps that's OK. What if there is an employee 100 but there is a corrupt block in the index causing the query to fail with ORA-01578: ORACLE data block corrupted, or not, depending on the execution plan? It does nothing and doesn't tell you, and you'll think there's no employee 100.
I am trying to update salary column in my table using cursors.
This is my code:
declare
cursor c1 is
select * from emp2_1030082;
begin
for c3 in c1
loop
if(c3.salary>10000)
then
update emp2_1030082 set c3.salary=c3.salary + c3.salary/10 ;
elsif(c3.salary<=10000)
then
update emp2_1030082 set c3.salary= c3.salary + c3.salary/20 ;
end if;
end loop;
end;
But I'm getting this error:
ORA-06550: line 9, column 47:
PL/SQL: ORA-00904: "C3"."SALARY": invalid identifier
ORA-06550: line 9, column 1:

ORA-06550: line 12, column 1:
PL/SQL: SQL Statement ignored
06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.
*Action:
The first question is, do you really need to do this in a cursor? Because executing these two statements should do what you want:
update emp2_1030082 set salary=salary + salary/10 where salary > 10000;
update emp2_1030082 set salary=salary + salary/20 where salary <= 10000;
Meanwhile, the error you are getting is because in
update emp2_1030082 set c3.salary=c3.salary + c3.salary/10 ;
By using the c3. in set c3.salary you are referring to the cursor instead of the column name in the table that you want to update. Just salary (and in the other update as well) should make the error go away, BUT, you will update all rows with every update, so pretty sure that's not what you want.
To do it with a cursor, you should remove the the c3. from where it doesn't belong, and then add a where clause to update only the current record. Hopefully you have some kind of unique ID, and then it would be something like:
update emp2_1030082 set salary=c3.salary + c3.salary/10 where id = c3.id;

Your procedure expects an out parameter which you also need to provide:
declare
add_result number;
begin
addition(4,5,add_result);
