I need was playing around with sql developer and I have ran into a wall here...
I need to run a simple update query on a table and I want to pass in an array of Ids and update all the rows pointed by those Ids.
I have written the following stored procedure
PROCEDURE SAMPLE_PROCEDURE(SAMPLE_ARRAY IN NUM_ARRAY)
AS
BEGIN
UPDATE RETURNLIST_PICKLIST_MAPPING
SET PICKLIST_ID = 1111111
WHERE RETURNLIST_ID IN (SELECT * FROM TABLE(SAMPLE_ARRAY));
END SAMPLE_PROCEDURE;
NUM_ARRAY is a custom type defined as follows
create or replace
TYPE NUM_ARRAY
AS VARRAY(40) OF NUMBER(38, 0);
When I run the stored procedure in sql developer I want to input the value for SAMPLE_ARRAY. I have tried (2222,1111,1234) and [2222,1111,1234] and {2222,1111,1234} and each time I get "expression is of wrong type" error.
I desperate need help with this guys....
You did not show how did you assign values to your varray variable. But, I believe you can do it like this:
DECLARE
V_T NUM_ARRAY;
BEGIN
V_T := NUM_ARRAY(1,2,3);
SAMPLE_PROCEDURE(V_T);
END;
/
In general, you can define a standalone VARRAY as follows:
CREATE Or REPLACE TYPE varray_type_name AS VARRAY(n) OF <element_type>;
Or, within PL/SQL block:
TYPE varray_type_name IS VARRAY(n) of <element_type>

I am trying to accept user input inside of a stored procedure and assign it to a VARCHAR variable. For some reason I get error
PLS-00201: identifier 'userinput' must be declared.
Any ideas? I have to use this later down the line to see how many times the input appears in a table.
CREATE OR REPLACE PROCEDURE nums
AS
x_num VARCHAR(20);
BEGIN
x_num := &input;
dbms_output.put_line('You entered: ' || x_num);
END;
/
Procedures cannot receive user input in response to a prompt, PLSQL is NOT interactive. When you have that you are not actually communicating with the database. What is actually happening is symbol substitution were SQLPLUS or other interface (Toad , SQL Developer, ...) is actually intercepting symbol, requesting the input, and physically changing the script before submitting it to the database. If you want a stored procedure you will need to use a parameter as #HereGoes suggested and then provide the user a script as follows:
Begin
nums(pInput => &Input);
end ;
Or provide an application interface to receive the input value and call the procedure or allow user access through SQLPLUS or other interface and let them enter the script - not recommended.
I suggest making the input a parameter.
CREATE OR REPLACE PROCEDURE nums (pInput IN VARCHAR2)
AS
x_num VARCHAR(20);
BEGIN
x_num := pInput ;
dbms_output.put_line('You entered: ' || x_num);
END;

I need to print results of variables in Teradata stored procedures, but print does not work in teradata, should I use the below method or please suggest the proper one:
My code:
REPLACE PROCEDURE Name()
---some code goes here
BEGIN
TRANSACTION;
SET var1= var2+ 3;
SET var3= var2;
/* !!! PRINT var1*/
/* !!! PRINT var3*/
end;
--some code here
I used the out in stored procedure declaration, suggest me another way to print the values of variable:
REPLACE PROCEDURE Name(out var1, out var3)
As long as there's only a single line of values has to be returned you can utilize OUT variables.
For multiple lines you can use a Volatile Table where those lines are inserted and a final DYNAMIC RESULT SET returns them as an answer set.
If you want to print the value of a variable inside a stored procedure I assume you are asking in the context of debugging the store procedure. Teradata doesn't appear to have the debugging tricks that other databases provide, e.g. RAISE and NOTICE. One workaround is the create a log table with at least one column, message VARCHAR(500) and then insert your debugging messages into that table.
I am working on a Netezza SP and is stuck with a problem.
I have a SP, defined as say:
CREATE OR REPLACE PROCEDURE MY_PROC(VARCHAR(ANY)) RETURNS INTEGER LANGUAGE NZPLSQL
AS
BEGIN_PROC
DECLARE
v_temp ALIAS FOR $1;
/* Other decalarations */
result_ts INTEGER;
BEGIN
result_ts := 0;
/* Procedure Body */
RETURN result_ts;
EXCEPTION WHEN OTHERS THEN
RAISE NOTICE 'Exception Raised: %', SQLERRM;
END;
END_PROC;
If I am running this SP with one value, such as:
SELECT MY_PROC('TEST_INPUT');
But if I am trying to run it with a column value, such as:
SELECT MY_PROC(TEST_COLUMN) FROM TEST_TABLE;
Its giving me error as:
ERROR: Can't use a stored procedure in this context
I know that in the second scenario I am passing an Array (i guess) but this is not what the Procedure has expected.
Now I am trying to have a procedure that can accept these kind of values but could not succeeded so far, LOOPing and all I have taken care but only problem is the Argument which I don't know how to pass.
Any help would be appreciated, let me know if I need to provide any extra info on this.

Stored procedures in Netezza, as of v7.2, can only be called in the following ways, as documented here.
CALL sproc_name(...);
EXEC sproc_name(...);
SELECT sproc_name(...);
Note that the SELECT form does not allow a FROM clause.
If you want the stored procedure to act on a particular column from a particular table that changes from invocation to invocation, you could pass the names of those as arguments to the stored procedure and have the entirety of the SQL logic encoded within. You could even pass arbitrary code into the stored procedure to build a query internally.
The way you are trying to call it now is more like calling a user defined function, and that simply won't work with stored procedures here.
I'm using Delphi XE and FireBird 2.5.
Try use a TSQLStoredProc and give me the error "Cursor not returned from Query" when I put the Active property to TRUE.
An dummy example of storedproc
CREATE PROCEDURE NEW_PROCEDURE
RETURNS(
RDO SMALLINT)
AS
BEGIN
Rdo = 5;
/* Procedure body */
SUSPEND;
END;
As a workaround, a query like SELECT * FROM NEW_PROCEDURE should work (using TSQLQuery).
I think you are supposed to use the ExecProc method instead of Open / Active. Setting Active to true should only be used if your SQL Statement returns a ResultSet (a set of records), which yours doesn't.

All,
I am very new to stored procedures in general but I am struggling especially with those in Oracle. I have created a very simple example of what I am trying to accomplish and I am still getting the same error with this simplified version.
The example stored procedure is as follows:
CREATE OR REPLACE PROCEDURE ashish_test
AUTHID CURRENT_USER IS
BEGIN
DECLARE
v_tab VARCHAR2(50);
v_strSQL VARCHAR2(50);
BEGIN
v_strSQL := 'SELECT * FROM :1';
v_tab := 'ex.emp';
EXECUTE IMMEDIATE v_strSQL USING v_tab;
END;
END;
When I call the above stored procedure using CALL ashish_test(), I get :
Error Message http://web1.twitpic.com/img/12831839-06a3ea536df5d5a0a839eb83d9e59d25.4a3936b8-scaled.jpg
Based on this article (Look for Example 7-1), USING keyword should replace the numbered placeholder (:1) within v_strSQL with the value stored in v_tab. However, I keep getting invalid table error. I am guessing it's because EXECUTE IMMEDIATE is unable to replace the placeholder with the value for some reason but I am not sure why that is. Does anyone know if I am doing something stupid here?
I am running this on Oracle 10g database & using PL/SQL Developer.
The USING clause is only for bind variables (i.e. where you would use column names in a select statement), not table names. Typical usage would look like this:
Select col1 from table1 where col2 = :a
If you want to use variable table names use something like this:
v_tab := 'ex.emp';
v_strSQL := 'SELECT * FROM ' || v_tab;
EXECUTE IMMEDIATE v_strSQL;
