I wan to create random data in Oracle table:
CREATE TABLE EVENTS(
EVENTID INTEGER NOT NULL,
SOURCE VARCHAR2(50 ),
TYPE VARCHAR2(50 ),
EVENT_DATE DATE,
DESCRIPTION VARCHAR2(100 )
)
/
I tried this:
BEGIN
FOR loop_counter IN 1..1000
LOOP
INSERT INTO EVENTS (EVENTID, SOURCE, TYPE, EVENT_DATE, DESCRIPTION) VALUES (loop_counter, loop_counter, 'warning',
DBMS_RANDOM.VALUE(TO_CHAR(DATE '2000-01-01','J') ,TO_CHAR(DATE '9999-12-31','J')), dbms_random.value(1,100));
END LOOP;
COMMIT;
END;
I get this error exception
Error report - ORA-06550: line 5, column 13: PL/SQL: ORA-00932:
inconsistent datatypes: expected DATE got NUMBER ORA-06550: line 4,
column 1: PL/SQL: SQL Statement ignored
06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.

Can you give me advice how I can fix this issue?
Use:
BEGIN
FOR loop_counter IN 1..1000 LOOP
INSERT INTO "EVENTS" (EVENTID, "SOURCE", TYPE, EVENT_DATE, DESCRIPTION)
VALUES (loop_counter, loop_counter, 'warning',
TO_DATE(TRUNC(DBMS_RANDOM.VALUE(TO_CHAR(DATE '2000-01-01','J') ,TO_CHAR(DATE '9999-12-31','J'))),'J')
,dbms_random.value(1,100)
);
END LOOP;
COMMIT;
END;

Rewrite random date generation
Also, if you use PL/SQL Developer by Allroundautomations, you can find out
good tool for this job: Data Generator.
It can be very useful, because it can help to generate some data
in any types and place it to a tables.
(see screenshot attached)
INSERT INTO EVENTS (EVENTID, "SOURCE", TYPE, EVENT_DATE, DESCRIPTION)
SELECT level, level, 'warning',
TO_DATE(TRUNC(DBMS_RANDOM.VALUE(TO_CHAR(DATE '2000-01-01','J') ,TO_CHAR(DATE '9999-12-31','J'))),'J')
,dbms_random.value(1,100)
FROM DUAL
CONNECT BY LEVEL <= 1000;

Using Oracle SQL, I have several SQL Queries with manual bind variables that are used to create a table as follows:
What I would like to do is to change the define anfang to (select c_year_beginning from master_date_automation).
I have tried several combinations of bind variables but could not make it work (edited with DEL comments):
begin
execute immediate 'DROP TABLE A_TEST_TABLE'
end;
/
begin
execute immediate 'create table A_TEST_TABLE (
user varchar2(100),
product varchar2(100),
datum date)';
end;
/
BEGIN
DECLARE
v_c_year_ytd DATE;
BEGIN
SELECT c_year_ytd Into v_c_year_ytd FROM master_date_automation;
BEGIN
SELECT usr.datum || ','
|| usr.user || ','
|| usr.product
INTO A_TEST_TABLE
FROM users_table usr
WHERE usr.datum = v_c_year_ytd
AND kto.kontonummer = '00510199065';
END;
END;
END;
ERROR message (edited after Del comment):
Error report -

Would be really thankful if someone could help me out.
Thousand thanks in advance!
So, to sum up my comments from above, you don't need PL/SQL to do this. You could do all of your script with straight SQL:
CREATE TABLE A_TEST_TABLE
(
user varchar2(100),
product varchar2(100),
datum date
);
INSERT INTO a_test_table
SELECT usr.user,
usr.product,
usr.datum
FROM users_table
WHERE usr.datum = (SELECT c_year_ytd FROM master_date_automation)
AND usr.user= '123456789'
Drop the table if you need to first.
You don't need to use dynamic SQL inside a PL/SQL block to create the tables; you can do it using SQL statements:
DROP TABLE A_TEST_TABLE;
CREATE TABLE A_TEST_TABLE (
user_name varchar2(100),
product varchar2(100),
datum date
);
Note: USER is a reserved word and you CANNOT use it as an unquoted identifier; you will need to find another identifier such as user_name or you will have to use a quoted identifer and refer to it as "USER" everywhere it is used (however, that is bad practice).
Then if you want to use PL/SQL you can use:
DECLARE
v_c_year_ytd DATE;
BEGIN
SELECT c_year_ytd
Into v_c_year_ytd
FROM master_date_automation;
INSERT INTO a_test_table (datum, user_name, product)
SELECT datum,
user_name
product
FROM users_table
WHERE datum = v_c_year_ytd
AND kontonummer = '00510199065';
END;
/
But it would be much simpler to just use one SQL statement:
INSERT INTO a_test_table (datum, user_name, product)
SELECT datum,
user_name
product
FROM users_table
WHERE datum = (SELECT c_year_ytd FROM master_date_automation)
AND kontonummer = '00510199065';
It's my first question.I have such task in school to do.We have table with columns NAME,PARENT,MONEY,CITY.The task is to produce output names,money and average money of descendants for whom it is true, that the average money
of the descendants is greater than the person's money.
I write this code but can't understand error...
CREATE OR REPLACE PROCEDURE rich_avg_descendant IS
cnt INTEGER;
BEGIN
FOR rec IN (SELECT name, money,AVG(money) FROM ourtable) loop
SELECT count(*) INTO cnt FROM ourtable
GROUP BY name
HAVING AVG(money)> rec.money
START WITH name = rec.name CONNECT BY PRIOR name = parent;
IF cnt > 0 THEN dbms_output.put_line(name,money,AVG(money)); END IF;
END loop;
END;
/
Error is in START WITH clause that is START underlined.
Error starting at line : 14 in command -
BEGIN rich_avg_descendant(); END;
Error report -
ORA-06550: line 1, column 7:

Can you please tell my mistake in this code?
Thanks in advance.
the connect by clause should be preceding the start with clause
I need help to solve this issue. The Driver_ID exists in two tables, Driver and Driver_Deliveries. I need it to display the First_Name, Surname & Driver_ID for the Driver ID's that do not appear in the Driver_Deliveries table. I'm using Oracle SQL Developer with Oracle 11G.
DECLARE
FIRSTNAME VARCHAR2(20);
SUR_NAME VARCHAR2(20);
DRIVERID VARCHAR2(5);
BEGIN
FOR i IN
(
SELECT
FIRST_NAME,
SURNAME,
a.DRIVER_ID
INTO
FIRSTNAME, SUR_NAME, DRIVERID
FROM
DRIVER_DELIVERIES,
DRIVER a,
WHERE NOT EXISTS(SELECT * FROM DRIVER_DELIVERIES WHERE DRIVER_DELIVERIES.DRIVER_ID = a.DRIVER_ID);

LOOP
DBMS_OUTPUT.PUT_LINE('FIRST NAME :' ||I.FIRST_NAME);
DBMS_OUTPUT.PUT_LINE('SURNAME :' || I.SURNAME);
DBMS_OUTPUT.PUT_LINE('DELIVERY JOB REQUIRED: YES ');

You need to select into something with a simple query in a PL/SQL block, but you've taken that rule too far; because your cursor loop variable i is an implicit record type that is already available to take the query results.
You also have an extra comma in your cursor query's select list, and the from clause. And an extra semicolon after the where clause.
So with that loop syntax you need:
...
FOR i IN
(
SELECT
FIRST_NAME,
SURNAME,
a.DRIVER_ID
FROM
DRIVER_DELIVERIES,
DRIVER a
WHERE
...
Though you should really use explicit join syntax, which would make it more obvious that you currently have no link between the two tables in your where clause. But you don't actually want to refer to driver_deliveries there at all - you're getting all the data from the driver table. You only need to refer to that within the exists clause. (And I've just noticed you've spelled the table name incorrectly in that clause too).
So modifying that further:
need:
...
FOR i IN
(
SELECT
FIRST_NAME,
SURNAME,
DRIVER_ID
FROM
DRIVER a
WHERE NOT EXISTS(
SELECT null FROM DRIVER_DELIVERIES
WHERE DRIVER_DELIVERIES.DRIVER_ID = a.DRIVER_ID)
)
LOOP
...
You don't appear to need PL/SQL for this, but if you have to...
I've got a problem with trying to select something from a object table into my own local variable. Here's some basic code.
create type my_obj as object
(
my_number number
)
/
create table my_table of my_obj;
/
insert into my_table values (my_obj(123))
/
declare
my_holder my_obj;
begin
select * into my_holder from my_table where rownum = 1;
dbms_output.put_line(my_holder.my_number);
end;
The error I'm getting out of it is
Error starting at line : 86 in command -
declare
my_holder my_obj;
begin
select * into my_holder from my_table where rownum = 1;
end;
Error report -
ORA-06550: line 4, column 10:

ORA-06550: line 4, column 3:

06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.

Any clues on why this might be failing?
The select returns the variables from the object not the object itself so if you wanted to get it to work the way you have it you would need to declare that you want the object returned as below.
select my_obj(my_number) into my_holder from my_table where rownum = 1;
Hope this helps
I'm trying to learn a bit of PL-SQL using a tutorial by examples book, but one of the suggested codes return the following error when run:
ORA-06550: line 10, column 48: PL/SQL: ORA-00947: not enough values

Could you please help me understand what I'm doing wrong?
Many thanks in advance!

Oracle 11g R2 Schema Setup:
create table product (code integer primary key, name varchar2 (20), type varchar2(8),price number(4,2),update_dt date);

you are trying to insert 5 values from your select into four variables.
This is correct:
select code, type, name, price, update_dt
into code_var, type_var, name_var, price_var, update_dt_var
from product
where name='Arancia';
