I have simple plsql program, basically what I would like to do is to calculate the length of the name which is dynamic input to plsql and then loop based on the length.
When I give pre-defined value like v_name = 'Dex' it works but when I give v_name = &name it throws an error message saying Dex must be declared.
Appreciate if any one can shed light on this issue. Please find error and program details below:

v_loop_count := 0;

In SQL Developer (and in sqlplus), you can define substitution variables such as you're doing that start with &. But these substitution variables are unlike variables or literals in your code. These substitution variables will only be replaced textually, before the code gets parsed and executed.
If you have
v_name := &name;
Then the textual replacement will yield this code:
v_name := Dex;
Because you don't have a variable named DEX, you get the error you mentioned.
As mentioned in the comments, placing single-quotes around the substitution variable is the answer.
v_name := '&name';
This will get replaced with
v_name := 'Dex';
which is what you wanted -- the string value 'Dex'.

I have a oracle cursor which I have created to facilitate concurrency. This is my cursor.
create or replace FUNCTION get_unlocked_records RETURN table_to_test%ROWTYPE IS
CURSOR c IS SELECT * FROM table_to_test where status_code = 5 FOR UPDATE SKIP LOCKED;
record_to_get table_to_test%ROWTYPE;
BEGIN
OPEN c;
FETCH c INTO record_to_get;
CLOSE c;
RETURN record_to_get;
END;
When I do the testing in 2 separate sql sessions using these commands,it gives the following errors.
declare
record_to_gets table_to_test%ROWTYPE;
begin
exec :record_to_gets := get_unlocked_records;
dbms_output.put_line(record_to_gets);

What is the error that I am doing here ?
Since my ultimate goal is to call the function and get the result in java, how to call this function to get the first record in java ?
Thanks in advance.
EXEC[UTE] is a SQL*Plus command and prepending variable with a colon is done in SQL*Plus, but in PL/SQL EXECUTE IMMEDIATE might be used whereas that's not needed in your case, only using such an assignment without prepending the local variable is enough :
DECLARE
record_to_gets table_to_test%ROWTYPE;
BEGIN
record_to_gets := get_unlocked_records;
DBMS_OUTPUT.PUT_LINE(record_to_gets.col1);
DBMS_OUTPUT.PUT_LINE(record_to_gets.col2)
END;

What is going on here? appreciate your help.
This error you generally face when you deal with BOOLEAN datatype as OUT parameter and you try to print it or do any operation with any other inbuilt Oracle packages. You cannot directly use BOOLEAN datatype in dbms_output.put_line or any other DBMS package. For instance,if you want to print the OUT parameter you need to use sys.diutil.bool_to_int.
See below example which demonstrate the error you faced when you try to execute as below:
DECLARE
inx VARCHAR2(100):='ABC';
var BOOLEAN;
BEGIN
CLEAR_INDEX(INDEX_NAME1=>inx ,IT_WORKED =>var);
dbms_output.put_line(var);
END;
You face the issue:
ORA-06550: line 6, column 3:
PLS-00306: wrong number or types of arguments in call to 'PUT_LINE'
ORA-06550: line 6, column 3:
PL/SQL: Statement ignored
06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.
*Action
To overcome such issue you must execute as below:
DECLARE
inx VARCHAR2(100):='ABC';
var BOOLEAN;
var1 varchar2(10);
BEGIN
CLEAR_INDEX(INDEX_NAME1=>inx ,IT_WORKED =>var);
var1:=CASE WHEN (sys.diutil.bool_to_int(var)) = 1 THEN 'TRUE'
WHEN (sys.diutil.bool_to_int(var)) = 0 THEN 'FALSE'
END;
dbms_output.put_line(var1);
END;
Output:
anonymous block completed
Mine is a similar case, however, a different call to a function, which has return type as Boolean and the input to the function is varchar2.
So, this is what I am doing:
Declare
v_ret1 varchar2(1000);
v_ret BOOLEAN;
Begin
v_ret := CASE WHEN SEI_PROCESS_MF_MNL_INVC_PKG.f_process_mf_mnl_invc(v_ret1) = 1 THEN 'TRUE'
WHEN SEI_PROCESS_MF_MNL_INVC_PKG.f_process_mf_mnl_invc(v_ret1) = 0 THEN 'FALSE'
END;
dbms_output.put_line(v_ret);
end;
I just wanted to see output of v_ret so that I can use that for further decision making. If v_ret is of type Boolean, the output should be either "TRUE" or "FALSE".
This question already has an answer here:
PLS-00201: identifier 'USER INPUT' must be declared

Why do I get this error? If the variable declaration is the same type as the column shouldn't this work. The nursing_unit_id is a varchar2(10). It worked like this for me when the ID was a NUMBER;
Error I get:
Error report -
ORA-06550: line 13, column 13:
PLS-00201: identifier 'ISS' must be declared
SET SERVEROUTPUT ON;
DECLARE
v_unit ADMISSIONS.NURSING_UNIT_ID%TYPE := &v_unit;
v_admissions ADMISSIONS%ROWTYPE;
CURSOR c_admissions IS
SELECT *
INTO v_admissions
FROM ADMISSIONS
WHERE NURSING_UNIT_ID = v_unit;
BEGIN
FOR r_admissions IN c_admissions
LOOP
DBMS_OUTPUT.PUT_LINE(r_admissions );
END LOOP;
END;
If nursing_unit_id is varchar2(10) and you've defined the substitution variable &v_unit as ISS, then you have to enclose the reference to the substitution variable in quotes, to make it a string:
v_unit ADMISSIONS.NURSING_UNIT_ID%TYPE := '&v_unit';
If you run your code in SQL*Plus or SQL Developer with set verify on, you'll see the before and after values for that substitution, which would show it it trying to to do:
v_unit ADMISSIONS.NURSING_UNIT_ID%TYPE := ISS;
instead of what you'd get with it quoted:
v_unit ADMISSIONS.NURSING_UNIT_ID%TYPE := 'ISS';
You will still get other errors; the next one is:
PLS-00306: wrong number or types of arguments in call to 'PUT_LINE'
You've defined v_admissions as a row type, which means it's a record. You can't write a whole record out in one go with dbms_output, you have to refer to each field separately, e.g. (using your amended code, where `r_admissions is also implicitly of that same row type):
DBMS_OUTPUT.PUT_LINE(r_admissions.nursing_unit_id);
Having an into clause in the cursor definition isn't useful; it isn't actually populated, so you can remove that clause and the v_admissions variable declaration. You don't really need the v_unit local variable either, you can use the substitution variable directly; and there are various cursor forms you can use, such as:
SET SERVEROUTPUT ON;
BEGIN
FOR r_admissions IN (
SELECT *
FROM ADMISSIONS
WHERE NURSING_UNIT_ID = '&v_unit'
)
LOOP
DBMS_OUTPUT.PUT_LINE(r_admissions.nursing_unit_id);
-- and anything else you want to do with that row's data
END LOOP;
END;

I'm currently trying to execute a stored procedure in Oracle PL SQL. I keep running into the same error for the below with execution.
I've tried both execution with the same error
SET SERVEROUTPUT ON;
EXEC get_phone(200.00,500.00);

c_maxprice products.price%type;
BEGIN
c_minprice := get_phone(200);
c_maxprice := get_phone(500);
END;
ERROR from executing the above:

****Sample Snip-its form my code:
CREATE OR REPLACE PROCEDURE get_phone

c_maxprice IN products.price%type,
i_result OUT VARCHAR2
) AS
--Checking if starting price range is valid or not
IF c_minprice IS NULL THEN
i_result := 'Starting price range should be valid and cannot be empty';
RAISE V_MINPRICE; -- Raising exception if starting price is null
END IF;
--Checking if end price range is valid or not
IF c_maxprice IS NULL THEN
i_result := 'End price range should be valid and cannot be empty';
RAISE V_MAXPRICE; -- Raising exception if end price is null
END IF;
Your procedure requires three parameters so you have to pass in three parameters
DECLARE
l_result varchar2(100);
BEGIN
get_phone( 200, 500, l_result );
END;
/
should work. Of course, your procedure seems rather pointless. And if the goal is simply to return a result, you really ought to be using a function rather than a procedure with an out parameter.
get_phone expects 3 arguments, c_minprice, c_maxprice and i_result. You are only passing it one number. Pass it the rest of the arguments.
I don't understand why service is complaining with
Fehler(36,11): PL/SQL: ORA-00904: "FOUND_VP": invalid identifier
Variable is declared in the first begin...
Is it not possible to use variable directly in queries ?
when trying store following procedure :
create or replace PROCEDURE fpwl_update_vp(
my_zn IN NUMBER, my_verwaltung IN VARCHAR2 , my_variante IN NUMBER, my_vp IN NUMBER
) IS

INFOversion number := 25;
BEGIN -- search SYFA_VP
SELECT SYFA_VP

FROM FPWL_VP_MAPPING
WHERE INFO_VP=search_VP ;
exception
when no_data_found then
dbms_output.put_line ('Kein SYFA VP : Importiere aus SYFA');
--found_VP:=:=cus_info25.pa_info_data.fn_insert_syfa_vp(my_vp,25);
WHEN OTHERS THEN
ROLLBACK;
RETURN;
END; -- SYFA VP
-- Update VP
UPDATE IFT_INFO_LAUF
SET vp = found_VP
WHERE id_kopf IN

AND verwaltung= my_verwaltung
AND variante = my_variante
)

EXCEPTION

END ;
Your problem is that found_VP is going out of scope.
Move the contents of the "DECLARE" block to just after the "IS":
create or replace PROCEDURE fpwl_update_vp(
my_zn IN NUMBER, my_verwaltung IN VARCHAR2 , my_variante IN NUMBER, my_vp IN NUMBER
) IS
search_VP IFT_INFO_LAUF.VP%TYPE;
found_VP IFT_INFO_LAUF.VP%TYPE;
INFOversion number := 25;
BEGIN
BEGIN -- search SYFA_VP
etc
Make sure that
FPWL_VP_MAPPING.SYFA_VP
is the same type with
IFT_INFO_LAUF.VP
and make sure that
SELECT SYFA_VP INTO found_VP FROM FPWL_VP_MAPPING WHERE INFO_VP=search_VP ;
does not return multiple rows.
But I doubt that is the case with the error that you have given.
Since the error message refers to line 36 and the reference to found_VP in your code sample is on line 18, you've omitted the part of the code that actually has the problem.
It looks like you have a scope problem; you're declaring found_VP in an inner block (one level of DECLARE/BEGIN/END) and referring to it outside that block, either in the parent block or another one at the same level. The issue isn't where you're selecting into found_VP, it's (I think) that you're referring to it again later on, beyond the code you've posted, and therefore outside the block the variable is declared in.
To demonstrate, I'll declare l_name in an inner block, as you seem to have done:
create or replace procedure p42 is
begin
declare
l_name all_tables.table_name%TYPE;
begin
select table_name
into l_name -- this reference is OK
from all_tables
where table_name = 'EMPLOYEES';
end;
select table_name
into l_name -- this reference errors
from all_tables
where table_name = 'JOBS';
end;
/

Notice that the error is reported against line 13, which is in the outer block; it doesn't complain about it in the inner block because it is in-scope there.
So, you need to declare the variable at the appropriate level. As Colin 't Hart says that is probably right at the top, between the IS and the first BEGIN, as that is the procedure-level DECLARE section (it doesn't need an explicit DECLARE keyword).
