I am Wrting a Stored Function As below in db2.
CREATE OR replace FUNCTION moc_enddate( IN v_date VARCHAR(6),

|| v_date;
SET v_temp = to_date(v_temp_string,'DDMMYYYY');
SET v_end_date = (v_temp + 19 days);
RETURN v_end_date;
EXCEPTION
WHEN no_data_found THEN
SET v_message = 'SqlDataException';
WHEN OTHERS THEN
SET v_message = 'OTHER';
END;
But I am getting the following Exception.
ERROR [42601] [IBM][DB2/AIX64] SQL0104N An unexpected token "EXCEPTION" was found following "RN V_END_MOC_DATE; ". Expected tokens may include.
"<psm_case>".
Maybe, you are using DB2 SQL PL instead of PL/SQL. There is a difference between these languages. If it's the case, the following condition should work:
create or replace procedure CreatePlants
begin
declare sqlstate char(5) default '00000';
declare ErrorMsg varchar(96);
declare exit handler for sqlexception
begin
set ErrorMsg = 'SQLSTATE=' concat sqlstate;
signal sqlstate '99001'
set message_text = ErrorMsg;
end;
create table plants
( ID dec(3), Location varchar(16),
primary key (ID));
label on table plants is 'Plant master';
insert into plants values
( 1, 'Lost Angeles'),
( 2, 'New Yolk'),
( 3, 'Last Vegas');
end

I started writing this stored procedure and I faced some issues when I try to pass a variable in my conditional statement.
I can use the parameter BANKN which works fine, but when never I passed the declared variable AC_t somehow the PL/SQL ignores it.
Any idea please what I'm missing here?
create or replace PROCEDURE TTEST1 (
CR IN VARCHAR2,
BANKN IN VARCHAR2,
P_CURSOR OUT SYS_REFCURSOR
)
AS
G_AC CHAR(10);
AC_t Billing.Account %Type;
BEGIN
IF BANKN = 'WLNV' AND AC_t = 'Private'
THEN
IF CR IN (
'EUR',
'CZK',
'USD'
)
THEN
OPEN P_CURSOR
FOR
SELECT G_AC AS GL_ACC,
Billing.Account AS ACC_Type
INTO
G_AC,
AC_t
FROM Billing
INNER JOIN invoice ON Billing.ACC_NO = invoice.ACC_NO;
END IF ;
END IF ;
END;
My aim here is to expand this code by using AC_t value from Billing.ACCount and retrieve what ever data that can be 'Private' or 'Public'.
To do this, I need to use case or IF statement, however when I use
Billing.ACCount, I got an error "not allowed in this context", for this reason I use synonym AC_t but this don't read values from Billing table unless I use it in WHERE clause.
ACC_NO
Account
1
Private
2
Public
Extended code:
IF BANKN = 'WLNV' AND AC_t = 'Private'
THEN
...
...
ELSIF IF BANKN = 'WLNV' AND AC_t = 'Public'
THEN
....
...
You cannot use SELECT ... INTO with a cursor and you need to declare a value for the ac_t variable (but since it is a column in the table you may want a WHERE clause in the cursor). Like this:
CREATE PROCEDURE TTEST1 (
p_CR IN VARCHAR2,
p_BANKN IN VARCHAR2,
P_CURSOR OUT SYS_REFCURSOR
)
AS
BEGIN
IF p_BANKN = 'WLNV'
AND p_CR IN ( 'EUR', 'CZK', 'USD' )
THEN
OPEN P_CURSOR FOR
SELECT G_AC AS GL_ACC,
b.account AS ACC_Type
FROM Billing b
INNER JOIN invoice i
ON b.ACC_NO = i.ACC_NO
WHERE b.account = 'Private';
END IF;
END;
/
Which, if you have the sample data:
CREATE TABLE invoice (acc_no, g_AC) AS
SELECT 1, 2 FROM DUAL;
CREATE TABLE billing (acc_no, account) AS
SELECT 1, 'Private' FROM DUAL;
Then you can call the procedure and print the contents of the cursor using:
DECLARE
cur SYS_REFCURSOR;
v_g_ac INVOICE.G_AC%TYPE;
v_ac_t BILLING.ACCOUNT%TYPE;
BEGIN
ttest1('EUR', 'WLNV', cur);
LOOP
FETCH cur INTO v_g_ac, v_ac_t;
EXIT WHEN cur%NOTFOUND;
DBMS_OUTPUT.PUT_LINE( v_g_ac || ', ' || v_ac_t );
END LOOP;
CLOSE cur;
END;
/
Which outputs:
2, Private

You shouldn't use the 'LOOP' keywords
You can use Sequence Storage Engine:

INSERT INTO `Time_Dim` (
`vdate_id`,

FROM (

I am trying to use the CLOB datatype as the output parameter in my stored procedure because its resultset exceeds the storage capacity of a var datatype.
How do I execute the procedure? Below are the commands I had run to execute.
I tried assigning the resultset to the the CLOB variable using the INTO query as shown in the query.
var cl CLOB;
EXECUTE procedure_name(:cl);
print cl;
How do i declare the binding variable because if you look at the first command, I am first initializing cl as var I am not able to initialize it as CLOB as it is giving out an error.
This is a sample of my procedure. The actual query in the procedure is 700 lines long.
CREATE OR REPLACE PROCEDURE procedure_name (cl OUT CLOB)
IS
BEGIN OPEN cl FOR
SELECT * FROM .....
statement 1
.
.

statement n
INTO cl

*Cause: Usually a PL/SQL compilation error.
*Action:
[TL;DR] VAR is a keyword for declaring a variable and is not a data type; your actual error is due to using invalid syntax when you tried to define your procedure and it has not compiled.
VAR is short for VARIABLE and defines a PL/SQL bind variable.
This declaration has the syntax:
VAR[IABLE] [variable [type] ]
where type represents one of the following:
NUMBER
CHAR
CHAR (n [CHAR | BYTE])
NCHAR
NCHAR (n)
VARCHAR2 (n [CHAR | BYTE])
NVARCHAR2 (n)
BLOB
BFILE
CLOB
NCLOB
REFCURSOR
BINARY_FLOAT
BINARY_DOUBLE
So with:
var cl CLOB;
you are declaring a variable using the VAR keyword and the variable is named cl and has the type CLOB.
Also, your CREATE PROCEDURE statement has a syntax error as you cannot have the single quotes around the procedure name. For example:
CREATE PROCEDURE procedure_name (clb OUT CLOB)
IS
BEGIN
clb := 'test';
END;
/
Then:
VAR cl CLOB;
EXECUTE procedure_name( :cl );
PRINT cl;
Outputs:
test

I am trying to develop web application based on tutorial example. I have created procedure cilveki_list which has many parameters. When I compile this code I get two errors:
1)PL/SQL: SQL Statement ignored
2)PL/SQL: ORA-00933: SQL command not properly ended
First error refers to line 'c_kods in varchar2 default null'
and the second one to line ' if p_action = 'INSERT' then'.
Proedure behaviour depends on the parameter 'p_action', if it is set to 'INSERT', then insertion is perfomed, if it is set to 'UPDATE', then table update is performed.
But what is wrong with porcedue, why I get those errors, when I try to compile it?

In addition to the Paddy's Answer you must use GetDate() Instead of DateTime() to get the current DateTime.
