I believe this question is very trivial. I' unable to select rows inside a stored procedure that I defined, nor inside a UDF. Here is the syntax that I used:
Create Or Replace Procedure GenerateSequence(
In InternalUnitID SmallInt,
In ObjectTypeID SmallInt)
Language SQL
Dynamic Result Sets 1
Not Deterministic
No External Action
Modifies SQL Data
Commit On Return Yes
Begin
Select Number
From Sequence
Where InternalUnit=InternalUnitID
And ObjectType=ObjectTypeID;
End
If I try to create the above procedure (by putting the definition in a SQL file and running it). I get the following error message:
DB21034E The command was processed as an SQL statement because it was not a valid Command Line Processor command. During SQL processing it returned:
SQL0104N An unexpected token "Select Number From Sequence Where Intern" was
found following "n Return Yes Begin ". Expected tokens may include: "".
LINE NUMBER=21. SQLSTATE=42601
Any clue what can be the cause of this problem?
My environment is DB2 10.5 Express on Windows.
My problem was that I needed to use a cursor in order to return the result set to the caller of the stored procedure.

I read (and tried) that I cannot use WITH UR in DB2 stored procedures. I am told that I can use SET OPTION to achieve the same. However, when I implement it in my stored procedure, it fails to compile (I moved around its location same error). My questions are:
Can I really not use WITH UR after my SELECT statements within a procedure?
Why is my stored procedure failing to compile with the below error
message?
Here is a simplified version of my code:
CREATE OR REPLACE PROCEDURE MySchema.MySampleProcedure()
DYNAMIC RESULT SETS 1
LANGUAGE SQL
SET OPTION COMMIT=*CHG
BEGIN
DECLARE GLOBAL TEMPORARY TABLE TEMP_TABLE AS (
SELECT 'testValue' as "Col Name"
) WITH DATA
BEGIN
DECLARE exitCursor CURSOR WITH RETURN FOR
SELECT *
FROM SESSION.TEMP_TABLE;
OPEN exitCursor;
END;
END
#
Error Message:
SQL0104N An unexpected token "SET OPTION COMMIT=*CHG" was found
following " LANGUAGE SQL
Here is code/error when I use WITH UR
CREATE OR REPLACE PROCEDURE MySchema.MySampleProcedure()
LANGUAGE SQL
DYNAMIC RESULT SETS 1
--#SET TERMINATOR #
BEGIN
DECLARE GLOBAL TEMPORARY TABLE TEMP_TABLE AS (
SELECT UTI AS "Trade ID" FROM XYZ WITH UR
) WITH DATA;
BEGIN
DECLARE exitCursor CURSOR WITH RETURN FOR
SELECT *
FROM SESSION.TEMP_TABLE;
OPEN exitCursor;
END;
END
#
line 9 is where the DECLARE GLOBAL TEMPORARY ... is
DB21034E The command was processed as an SQL statement because it was
not a valid Command Line Processor command. During SQL processing it
returned: SQL0109N The statement or command was not processed because
the following clause is not supported in the context where it is
used: "WITH ISOLATION USE AND KEEP". LINE NUMBER=9. SQLSTATE=42601
Specifying the isolation level:
For static SQL:
If an isolation-clause is specified in the statement, the value of that clause is used.
If an isolation-clause is not specified in the statement, the isolation level that was specified for the package when the package was bound to the database is used.
You need to bind the routine package with UR, since your DECLARE GTT statement is static. Before CREATE OR REPLACE use the following in the same session:
CALL SET_ROUTINE_OPTS('ISOLATION UR')
P.S.: If you want to run your routine not only 1 time in the same session without an error, use additional WITH REPLACE option of DECLARE.
If your Db2 server runs on Linux/Unix/Windows (Db2-LUW), then there is no such statement as SET OPTION COMMIT=*CHG , and so Db2 will throw an exception for that invalid syntax.
It is important to only use the matching Db2 Knowledge Centre for your Db2 platform and your Db2-version. Don't use Db2-Z/OS documentation for Db2-LUW development. The syntax and functionalities differ per platform and per version.
A Db2-LUW SQL PL procedure can use with ur in its internal queries, and if you are getting an error then something else is wrong. You have to use with ur in the correct syntax however, i.e in a statement that supports this clause. For your example you get the error because the clause does not appear to be valid in the depicted context. You can achieve the desired result in other ways, one of them being to populate the table in a separate statement from the declaration (e.g insert into session.temp_table("Trade ID") select uti from xyz with ur; ) and other ways are also possible.
One reason to use the online Db2 Knowledge Cenbtre documentation is that it includes sample programs, including sample SQL PL procedures, which are also available in source code form in the sample directory of your DB2-LUW server, in addition to being available on github. It is wise to study these, and get them working for you.
I am creating a stored procedure for db2. But it is giving an error saying that
"SQL Error [42601]: An unexpected token "END-OF-STATEMENT" was found
following "SS_TOKEN_BAK". Expected tokens may include: " END IF"..
SQLCODE=-104, SQLSTATE=42601, DRIVER=4.23.42".
Following is my stored procedure.
CREATE OR REPLACE PROCEDURE TOKEN_CLEANUP_SP
BEGIN
DECLARE batchSize INTEGER;
-- ------------------------------------------
-- CONFIGURABLE ATTRIBUTES
-- ------------------------------------------
SET batchSize = 10000; -- SET BATCH SIZE FOR AVOID TABLE LOCKS [DEFAULT : 10000]
-- ------------------------------------------------------
-- BACKUP IDN_OAUTH2_ACCESS_TOKEN TABLE
-- ------------------------------------------------------
IF EXISTS (SELECT TABLE_NAME FROM TABLES WHERE TABLE_NAME = 'IDN_OAUTH2_ACCESS_TOKEN_BAK')
THEN
DROP TABLE IDN_OAUTH2_ACCESS_TOKEN_BAK;
END IF;
END/
Is anyone face this type of issue. Any help on this would be much appreciated.
Verify that you have the end-of-statement delimiter configured correctly for whatever tool submits the 'CREATE OR REPLACE' procedure. Different tools have different ways to configure the block terminator (alternatively known end of statement delimiter). For command line scripts, use --#SET TERMINATOR / at the start of the file, other ways are possible.
Your code sample shows / as the block terminator, so you might want to use that character as the block delimiter. The semi-colon terminates statements inside the block.
Separately you should see that your code won't compile if the specified table does not exist in the implied schema at compilation time, because you are using static SQL. You may want to use dynamic SQL instead for the drop table statement (search for 'EXECUTE IMMEDIATE' examples).
My real stored procedure is much more complex, but DB2 can't even seem to create a dummy stored procedure that does absolutely nothing (that's why I'm posting this dummy procedure). The procedure is as follows
CREATE PROCEDURE SIMPLE_DECL_PROC()
LANGUAGE SQL
BEGIN
DECLARE v varchar(16);//the problem is here
END
I'm getting the following error:
2:59:31 [CREATE - 0 row(s), 0.000 secs] [Error Code: -104, SQL State: 42601]
DB2 SQL Error: SQLCODE=-104, SQLSTATE=42601, SQLERRMC=END-OF-STATEMENT;ECLARE v varchar(16);<psm_semicolon>, DRIVER=3.57.82
The error complains about the declare statement although I can't see anything wrong with it (tried removing the ; at the end but it didn't work).
If I remove the declare statement, the procedure is created successfully.
I tried to do this with DBVisualizer as well as SQL Squirrel.
I'm sure it's something simple that I'm missing but I can't find it. Needless to say, I've checked similar questions here on SO and elsewhere.
And finally, we're using DB2 9.7.
Thanks
Most SQL clients allow to set a so-called statement terminator. This is the character that is at the end of the entire statement. By default most clients use the semicolon (";"). For stored procedures often a different statement terminator needs to be chosen and set. This is because a stored procedure can include multiple SQL statements which are terminated, but only that ouf the entire stored procedure is relevant.
I'm using db2 and SQuirreL SQL
I'm trying to create a stored procedure with a simple select statement inside of it. When I omit the select statement in the following below and run the code, the procedure is created. Also this procedure can be dropped and called.
CREATE PROCEDURE test_procedure
LANGUAGE SQL
BEGIN
END
When I add in the select statement, I get Error: DB2 SQL Error: SQLCODE=-102, SQLSTATE=42601,...
CREATE PROCEDURE test_procedure
LANGUAGE SQL
BEGIN
SELECT column_name FROM table_name
END
If you go to IBM iseries information center is says:
SQL0104 SQLCODE -104 SQLSTATE 42601
Explanation: Token &1 was not valid. Valid tokens: &2.
It appears that I wasn't given the right permissions to execute the stored procedure. SQL0551N This link explains more about the issue.
The statement terminator in SQuirreL is called "Statement separator" and it can be defined in:
Menu Session > Session Properties... > tab SQL > at the end of the SQL square, the option Statement Separator.
This is valid in version 3.5.3
I am attempting to run a simple compound statement within the Query Editor of DB Solo 4.2.2
It appears I am unable to properly change the end of line delimiter. I am using DB2. Here is a simple example that gives the error:
--#SET TERMINATOR #
BEGIN ATOMIC
DECLARE id INT;
SET id = 10;
END #
--#SET TERMINATOR ;
Error is:
An unexpected token "INT" was found following "N ATOMIC DECLARE id". Expected tokens may include: "END-OF-STATEMENT"
Thanks in advance
DB2 only allows the semicolon to be used as a delimiter in Compound SQL. The syntax you are using appears to only be valid when using the db2batch utility (which comes with DB2 Linux/Unix/Windows).
Here is some relevant information from the Information Center (this is from the z/OS IC):
How to code multiple statements in an SQL procedure
Use a semicolon
character to separate SQL statements within an SQL procedure.
The procedure body has no terminating character. Therefore, if the
procedure contains only one statement, you do not need to put a
semicolon after that statement. If the procedure consists of a set of
nested statements, you do not need to put a semicolon after the
outermost statement.
