I need to write a procedure with input parameters like groupid and item ids(array)
I need to insert into a table with values(groupid,itemid[0]) all items like (1,11),(1,12),(1,13),etc. I have table with two columns (groupid,itemid). please help me to sort out this problem. I am trying to write merge but getting error
CREATE OR REPLACE PROCEDURE update_product_group_prc

You have a syntax error. Comment the "WHEN MATCHED THEN" fragment.

Can anyone tell me how to get the result from cursor which contains multiple table columns.
NOTE:
I want only two columns from the first procedure
I'm new to PL/SQL. I'm using oracle 11g XE along with sql developer. I'm trying to create to create an after insert trigger as follows
create or replace trigger tr1
after
insert ON
employee
for each row
begin
print :new.emp_id;
end;
The employee table is as follows
create table employee
( emp_id varchar2(5) primary key,
emp_name varchar2(10),
salary number,
company varchar2(10) foreign key references companies(comp_name)
);
When I run the statement I got a 'enter binds' window for the bind variable :new. But I was confused that why do I need to enter the value for :new since it is pseudorecord. Then I entered 'employee' as the values for :new. Now I'm getting the following error.
Error(2,8): PLS-00103: Encountered the symbol "" when expecting one of the following: := . ( # % ; The symbol ":=" was substituted for "" to continue.
Your problem is not in the :new pseudorecord. The error is coming from the usage of print, which is used to print the bind variable used in successful PL/SQL block or used in an EXECUTE command. For example, you can use it this way:
VARIABLE n NUMBER
BEGIN
:n := 1;
END;
/
Then
PRINT n;
But if you want to test the value being inserted, you can use DBMS_OUTPUT.PUT_LINE like this:
create or replace trigger tr1
after
insert ON
employee
for each row
BEGIN
dbms_output.put_line(:new.emp_id);
END;
/
Enable DBMS_OUTPUT window in your SQL Developer, then run
insert into employee values(1, 'empName', 1000, 'ABC');
You'll see 1 printed out.
However, you can always test the value from the table. Because the value should be already inserted into table. You can just query.
I have a Procedure like this,
create or replace
PROCEDURE SP_PROOF
( proof_id IN NUMBER
, Type1 IN VARCHAR2
, StatementType IN NUMBER
, Resultset OUT NUMBER
) AS
BEGIN
IF StatementType = 1 Then
INSERT INTO ID_Proof (proofid,Id_type)
VALUES (proof_id, Type1);
ELSIF StatementType=2 THEN
SELECT proofid,Id_type Into Resultset FROM ID_Proof;
ELSIF StatementType=3 THEN
UPDATE ID_Proof SET Id_type = Type1 WHERE proofid = proof_id;
ELSIF StatementType=4 THEN
DELETE FROM ID_Proof WHERE proofid = proof_id;
end if;
end;
Im getting an error like this,
Error(14,1): PL/SQL: SQL Statement ignored
Error(14,64): PL/SQL: ORA-00947: not enough values
Please help me to correct the error.
Line 14 is:
SELECT proofid,Id_type Into Resultset FROM ID_Proof;
You are selecting two values, proofid and Id_type, into a single scalar variable Resultset. But you also have no filter, so even if you changed that to select a single value then you'd get a too-many-rows error if there was more than one row in the table (and no-data-found if the table is empty).
It isn't clear what you want to happen; perhaps you want select id_type into resultset from id_proof, but from the parameters id_type is a string - so selecting that into a number variable is likely to fail too. Or perhaps you want all IDs for the specified type, in which case the type of result set would need to be a table type or a ref cursor.
Having separate procedures and functions would be probably be clearer, too.
DECLARE
v_name A.TRANSACTION_TYPE%TYPE :='SALARY';
v_salary A.SALARY%TYPE := 1000;
BEGIN
update A set v_name= v_salary where EMPID = 517;
-- PL/SQL: ORA-00904: "v_name": invalid identifier
--update A set SALARY = 1000 where EMPID = 517;
END;

My idea is to update table columns , but these column names are stored in variable. Is there any way to pass column names from variable ? Is there any options apart from Execute Immediate
Not sure if this will work in your situation, but I've written solutions where I wrote a script in SQLPlus and it "wrote" (using dbms_output.put_line or even just prompt) another script that did queries, and the columns/tables in those queries was determined by the logic in the SQLPlus script. Then I would execute as a script the output from my first script, and it would execute dynamically generated queries without ever needing execute immediate.
The following idea may work for multiple columns that are typed the same... As written, it will update all columns every time for a given record, but only the column specified by v_name will be changed to the value set in v_value; the other columns are simply updated to their existing value. The idea can be played with using DECODE, NVL or other similar conditional operators.
declare
v_name varchar2(20):= 'SAL';
v_value emptest.sal%TYPE := 5000;
begin
update emptest
set sal = ( select case when v_name = 'SAL' then v_value else sal end from dual),
comm = ( select case when v_name = 'COMM' then v_value else comm end from dual)
where empno = 7369;
commit;
end;
I am doing an school assigment where I need to get the last value of "code" so I can then insert next row with this code incremented. I tried to pull it out this way.
DECLARE
v_last_code f_shifts.code%TYPE;
BEGIN
SELECT LAST_VALUE(code) OVER (ORDER BY code)
INTO v_last_code
FROM f_shifts;
DBMS_OUTPUT.PUT_LINE('Last value is: ' || v_last_code);
END;
However I get ORA-01422: exact fetch returns more than one requested number of rows
and I have no idea why and how can a last_value be more than one row
Thanks !
You can use a nested table like this.
DECLARE
v_last_code f_shifts.code%TYPE;
TYPE t_tbl IS TABLE OF f_shifts.code%TYPE;
-- Above line creates the nested table type of the required type.
v_tbl T_TBL;
-- Above line creates the nested table variable.
BEGIN
SELECT code
BULK COLLECT INTO v_tbl -- collects all the values, ordered, into the nested table
FROM f_shifts
ORDER BY code;
v_last_code = v_tbl(v_tbl.LAST); -- gets the last values and puts into the variable
DBMS_OUTPUT.PUT_LINE('Last value is: ' || v_last_code);
END;
