I keep getting these problems when all I wanted was to display the maximum salary of an employee in a job id
ORA-06550: line 12, column 6:
PL/SQL: ORA-00933: SQL command not properly ended
ORA-06550: line 8, column 6:
PL/SQL: SQL Statement ignored
Here's my code:
DECLARE
lvc_jb_id VARCHAR2;
lvn_max_sal NUMBER;
BEGIN
SELECT max(salary), job_id
INTO lvn_max_sal, lvc_jb_id
FROM EMPLOYEES
group by job_id
DBMS_OUTPUT.PUT_LINE('MAX SALARY for job_id is'|| lvn_max_sal);
DBMS_OUTPUT.PUT_LINE('job id '|| lvc_jb_id);
END;
Can anyone tell what I did wrong?
Specify the size of the string.
eg: lvc_jb_id VARCHAR2(50);
End the select query with semicolon. Now it should work.

I have created following procedure:
create or replace function getDepartmentById(name varchar2)
return number
is v_dep number(10)
begin
--the sql statement is totally fine
select deptno into v_dep from dept where dname = name;
end;
/
but when I call
select getDepartmentById('SALES') into dep from dual;
I get this error message
Error report -
ORA-06550: line 20, column 14:
PL/SQL: ORA-06575: Package or function GETDEPARTMENTBYID is in an invalid state
ORA-06550: line 20, column 7:
PL/SQL: SQL Statement ignored
You need to add a return value for the function. It goes like this :
CREATE OR replace FUNCTION Getdepartmentbyid(name VARCHAR2)
RETURN NUMBER
IS
v_dep NUMBER(10);
BEGIN
--the sql statement is totally fine
SELECT deptno
INTO v_dep
FROM dept
WHERE dname = name;
RETURN v_dep;
END;
You can not use a INTO in your select statement. You should call the function like this.
select getDepartmentById('SALES') from dual;
#C:\Users\4\Desktop\dbdrop;
#C:\Users\4\Desktop\dbcreate;
SET SERVEROUTPUT ON;
DECLARE

END IF;

I am getting a pls-201 error when I try to reference a plsql table record in a query.
Here is an example of the issue:
DECLARE
TYPE trxtypeinforec IS RECORD(
NAME ra_cust_trx_types.NAME%TYPE
);
TYPE trxtypeinfotab IS TABLE OF trxtypeinforec
INDEX BY PLS_INTEGER;
g_inv_type trxtypeinfotab;
l_result VARCHAR2 (100);
BEGIN
g_inv_type(1).NAME := 'Test';
SELECT g_inv_type(qry.ID).NAME
INTO l_result
FROM (SELECT 1 ID
FROM dual) qry;
END;
Error report - ORA-06550: line 15, column 23: PLS-00201: identifier
'QRY.ID' must be declared ORA-06550: line 15, column 23: PLS-00201:

PL/SQL: SQL Statement ignored
06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.
*Action:
Retrieve the index from the SELECT first into a local variable and then assign the value from the associative array to l_result in a PL/SQL scope and not in an SQL scope:
DECLARE
TYPE trxtypeinforec IS RECORD(
NAME ra_cust_trx_types.NAME%TYPE
);
TYPE trxtypeinfotab IS TABLE OF trxtypeinforec INDEX BY PLS_INTEGER;
g_inv_type trxtypeinfotab;
idx PLS_INTEGER;
l_result ra_cust_trx_types.NAME%TYPE;
BEGIN
g_inv_type(1).NAME := 'Test';
SELECT 1
INTO idx
FROM DUAL;
l_result := g_inv_type(idx).NAME;
DBMS_OUTPUT.PUT_LINE( l_result );
END;
/
Outputs:
Test
db<>fiddle here
Please try using a cursor.
SET SERVEROUTPUT ON;
DECLARE
TYPE trxtypeinforec IS RECORD(
NAME ra_cust_trx_types.NAME%TYPE
);
TYPE trxtypeinfotab IS TABLE OF trxtypeinforec
INDEX BY PLS_INTEGER;
g_inv_type trxtypeinfotab;
l_result VARCHAR2 (100);
-- Query for retrieving index goes in the cursor or use existing cursor
CURSOR cur_id IS
SELECT 1 AS ID FROM DUAL;
BEGIN
-- Populate records here or put inside loop as required
g_inv_type(1).NAME := 'Test';
-- Loop through the cursor to get the relevant index
FOR rec in cur_id
LOOP
SELECT g_inv_type(rec.ID).NAME
INTO l_result
FROM DUAL;
dbms_output.put_line (l_result);
END LOOP;
END;
/
It will be helpful if we could get some more information on how the existing cursor is fetching index values.

I have below code which checks for table exists & proceed further.
Here problem is why its proceeding to else part even though table is not present in the database & also its returning "0"

You should make use of dynamic REFCURSOR to run a loop to drop tables dynamically.

I need to get comparison of columns between table and a view i choose to see if there are matching columns.(in PLSQL)
The columns that don't match need to be outputed as: column1 in view1 is missing in table1 etc.
This is so far i have done, but it gives me an error:
DECLARE
CURSOR c_col
IS
SELECT T.TABLE_NAME,
T.COLUMN_NAME,
V.TABLE_NAME,
V.COLUMN_NAME
FROM ALL_TAB_COLUMNS T

ON T.column_name=V.column_NAME
AND v.table_name='EMP_V'
AND v.owner ='HR'
WHERE T. OWNER ='HR'
and T.TABLE_NAME='EMPLOYEES';
v_table c_col%rowtype;
begin
OPEN C_col;
LOOP
FETCH C_col into V_TABLe;
EXIT when C_col%NOTFOUND;
DBMS_OUTPUT.PUT_LINE (v_table.table_name||' '||V_table.column_name);
end LOOP;
close c_col;
end;
this is the error i keep getting:
