DB2 procedure call literal error - db2

I'm trying to call a DB2 procedure using DBeaver.
The syntax I'm using is this:
{ call db.procedure_name ('1234','2345','3456') }
Then I get an error saying:
"Literal replacement prasing failed for procedure call... Failing SQL
text..."
When I call the same procedure like this:
{ call db.procedure_name (?,?,?) }
and insert the parameters manually it executes.
I'm quite new to DB2 and IBM troubleshooting sites aren't much of a help.
Can you guys help me out? Thanks.

Try call db.procedure_name (:1,:2,:3)
or alternatively, create global variables for each parameter
create or replace variable p1 integer default 123;
create or replace variable p2 decimal(5,2) default 123.45;
create or replace variable p3 char(5);
set p3 = '12345';
call db.procedure_name (p1,p2,p3);

Compare variables declared in Snowflake Stored procedure

I got a stored procedure as below
CREATE OR REPLACE PROCEDURE SP12
(argument1 VARCHAR,argument2 VARCHAR
)
if (argument1 <> argument2) { return N1 } else { return N2}
The issue is iam getting error while comparing argument1 <> argument2 (need to compare not equal to).
Is this correct method.
Thanks
is the the complete code for your Stored Procedure or is it just a snippet? If it is the full code then I suggest that you read the documentation again: CREATE PROCEDURE
You need a RETURNS statement in the header
How are you declaring/assigning values to N1 and N2?
If these suggestions don't help then please provide the full SP Code (if this is just a snippet) and also the error message you are getting

How to pass VARGRAPHIC to Stored procedures in DB2?

How can I call a sp with VARGRAPHIC variable type as input?
I've create this super simple sp that dose nothing and just for test, with following statement:
CREATE PROCEDURE MYPROCEDURE (IN VARNAME vargraphic(5) )
LANGUAGE SQL
P1: BEGIN
END P1
but when I call the sp in IBM Data Studio,it raises this error:
{? = call SCHEMA.MYPROCEDURE (?)}
[SQL0189] Coded Character Set Identifier 37 not valid.
Run of routine failed.
- Roll back completed successfully.
is there any problem in my sp code?
should I define CCSIDs? How and where?
I suspect that you would want to specify the CCSID of your parameter like this
call SCHEMA.MYPROCEDURE( CAST(? AS VARGRAPHIC(5) CCSID 65535) )
picking the correct CCSID number as appropriate

How to store the result of a select query into a variable(IBM DB2)?

I am trying to save the result of a query into a variable. I am using IBM DB2, but I can only store the result if I am declaring the variable inside a procedure.
My code is:
DECLARE #myvar INTEGER;
SET #myvar = (SELECT MAX(ID) FROM S0SCSQMS.S0SRPTCNAME);
and I receive the following errors:
For the first line:"SQL0104N An unexpected token "INTEGER" was found following "DECLARE #myvar ". Expected tokens may include: "END-OF-STATEMENT". LINE NUMBER=1. SQLSTATE=42601"
The error code does not tell me much. I looked for it on the IBM documentation.
Looking forward for an answer.
Thank you.
try this (work on iseries db2 v7r1)
CREATE OR REPLACE VARIABLE myvar INTEGER ;
SET myvar = (SELECT max( id_xp_dossier) FROM cilgprod.xp_dossier);
DROP VARIABLE myvar;

I can create a stored procure with invalid user defined function names in it

I just noticed that I could alter my stored procedure code with a misspelled user defined function in it.
I noticed that at 1st time I execute the SP.
Is there any way to get a compile error when an SP include an invalid user-defined function name in it?
At compile time? No.
You can, however, use some of SQL's dependency objects (if using MS SQL) to find problems just after deployment, or as part of your beta testing. Aaron Bertran has a pretty nice article rounding up the options, depending upon the version of SQL Server.
Here is an example using SQL Server 2008 sys object called sql_expression_dependencies
CREATE FUNCTION dbo.scalarTest
(
#input1 INT,
#input2 INT
)
RETURNS INT
AS
BEGIN
-- Declare the return variable here
DECLARE #ResultVar int
-- Add the T-SQL statements to compute the return value here
SELECT #ResultVar = #input1 * #input2
-- Return the result of the function
RETURN #ResultVar
END
GO
--Fn Works!
SELECT dbo.ScalarTest(2,2)
GO
CREATE PROCEDURE dbo.procTest
AS
BEGIN
SELECT TOP 1 dbo.scalarTest(3, 3) as procResult
FROM sys.objects
END
GO
--Sproc Works!
EXEC dbo.procTest
GO
--Remove a dependency needed by our sproc
DROP FUNCTION dbo.scalarTest
GO
--Does anything have a broken dependency? YES
SELECT OBJECT_NAME(referencing_id) AS referencing_entity_name,
referenced_entity_name, *
FROM sys.sql_expression_dependencies
WHERE referenced_id IS NULL --dependency is missing
GO
--Does it work? No
EXEC dbo.procTest
GO

Retrieve data from PostgreSQL Database using ADO.Net "System.Data.Odbc" (VB.Net)

Though I have been using SQL Server, Oracle from last decade, I have been asked to
do some research on PostgreSQL and after some initial investigation it is evident that I am now stuck on retrieving data from the PostgreSQL database using Function.
Using following piece of code to retrieve the data and getting error
('ERROR [26000] ERROR: prepared statement "mytabletest" does not exist;
'Error while executing the query)
Code Snippets
Dim oDBCommand As DbCommand = GetDBCommand(oConnectionType, "mytabletest", CommandType.StoredProcedure)
Dim dstResults As DataSet = GetDataSet(ConnectionTypes.ODBC, oDBCommand)
Public Function GetDataReader(dbType As ConnectionTypes, command As DbCommand) As DbDataReader
Try
Dim oConnection As DbConnection = GetDBConnection(dbType)
Dim oDBTransaction As DbTransaction = oConnection.BeginTransaction
command.Connection = oConnection
command.Transaction = oDBTransaction
'GETTING ERROR ON FOLLOWING LINE
'ERROR [26000] ERROR: prepared statement "mytabletest" does not exist;
'Error while executing the query
return command.ExecuteReader()
Catch ex As Exception
Throw ex
Finally
End Try
Return Nothing
End Function
Environement I am currently working on is following:-
32 Bit Machine.
Visual Studio 2010 + SP1
ODBC Prodiver: PostgreSQL Unicode 9.01.02.00
ADO.Net (System.Data.Odbc)
Please note that I am open to any suggestions i.e. if I am completely doing it wrong
OR partially etc. Please feel free to write.
In order to make it easier for you to create a same environment, please use following table/function definition.
--- Simple table to make things easier to understand. <br>
CREATE TABLE mytable
(
messagetypeid integer NOT NULL,
messagetype character varying(100) NOT NULL
)
-- Function to retrieve data. <br>
CREATE OR REPLACE FUNCTION mytabletest() <br>
RETURNS SETOF refcursor AS $$
DECLARE
ref1 refcursor;
BEGIN
OPEN ref1 FOR SELECT * FROM mytable;
RETURN NEXT ref1;
END;
$$ LANGUAGE plpgsql;
Please Note:
If I use <br>
Dim oDBCommand As DbCommand = GetDBCommand(oConnectionType, "SELECT * FROM mytable", CommandType.Text)
then system manages to retrieve information from the datbase without any issue, however, as I mentioned as soon we use "Function" it throws an exception.
During my failed efforts to search any solution from the internet someone mentioned that Table should be created with the lower case it so just for the sake of it I recreated with the lower case, however, problem persists.
I am unfamiliar with .net but I suspect you meant something more like:
GetDBCommand(oConnectionType, "SELECT myfunc()", CommandType.Text)
Or in the case of SETOF functions etc..
GetDBCommand(oConnectionType, "SELECT * FROM myfunc()", CommandType.Text)
PostgreSQL does not have 'stored procedures' per-ce. It does have functions and I believe that the client/server protocol has a method for preparing statements that can then be executed multiple times with different variables (to save on the cost of parsing the SQL), but this should be exposed via your client library.
