I want to group my database entries by an attribute and to know which entries are in each group at the same time. I collect the ids of the grouped entries with Oracle COLLECT function COLLECT Function
DECLARE
TYPE ids_type IS TABLE OF number(19, 0);
ids ids_type;
BEGIN
select cast(collect(r.id) as ids_type) into ids from rechnungsdaten r group by r.status;
END;
But then I get the error:
Error report - ORA-06550: Line 5, Column 44: PL/SQL:
ORA-00902: Invalid datatype ORA-06550: Line 5, Column 5:
PL/SQL: SQL Statement ignored
06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.
*Action:
What is wrong here?
You cannot use COLLECT function on a type declared in a PL/SQL anonymous block.
You have other options like
Create a database type and run your collect query.
create or replace TYPE ids_type IS TABLE OF number(19, 0);
SELECT
r.status,
CAST(COLLECT(r.id) AS ids_type)
FROM
rechnungsdaten r
GROUP BY
r.status;
Use a simple LISTAGG query to see the list of ids as a string
SELECT
r.status,
LISTAGG(r.id,',') WITHIN GROUP(
ORDER BY
id
)
FROM
rechnungsdaten r
GROUP BY
r.status;

I have the sample CUSTOMERS table.

and I have the following error message:

ORA-00904: : invalid identifier
00904. 00000 - "%s: invalid identifier"

*Action:
which refers to line:
OE.TYP_CR_CARD_NST(OE.TYP_CR_CARD('Visa',100000000000011)));
The definition of types are:
create or replace type typ_cr_card as object
( card_type VARCHAR2(25)
, card_num NUMBER);
create or replace type typ_cr_card_nst as table of typ_cr_card;
Can someone tell me, please, what is wrong with this insert line as it is the one provided by SQL DEVELOPER?
NOTE: Also, I tried to use a procedure which inserts values in this table and the error refers to TYP_CR_CARD_NST datatype.
I'm trying to create some output based on select items from APEX.
The case is as follows:
In APEX you select certain items.
APEX makes a nested table of those primary keys and call the function to create the output.
The function generates the output and returns it.
I already found out that I can't use locally defined nested tables in the where clause, but I am now stuck on the following:
My stored type:
CREATE OR REPLACE EDITIONABLE TYPE "T_NUMBERS" as table of NUMBER(10,0)
The part of the function that gives the ORA-06550 error:
DECLARE
c_asked T_NUMBERS;
BEGIN
c_asked := T_NUMBERS(21);
This is just a simple example of what is going wrong.
The error itself:
ORA-06550: line 9, column 23:
PL/SQL: ORA-00932: inconsistent datatypes: expected NUMBER got <schema_name>.T_NUMBERS
I have an insert statement that I am trying to run against an Oracle database. The insert statement is very simple, and I only want to insert a value into one column. The table itself has more than one column, but I am only interested in filling one of the columns with data. The format of my query is similar to the one below:
insert into myTable (col1) Values (val1)
However, this throws the following error:
ORA-00904: "col1": invalid identifier
I've checked to make sure that the column is named correctly, and my only other thought is that something is wrong with my syntax. There are no constraints on the table such as primary keys. Is it possible to only insert values into certain columns when executing an insert statement in Oracle?
Check that you didn't quote the column name on creation of the table. If you did, the column name is stored as you quoted it. For example:
create table table1 (
id number(2)
)
has a different column name to this
create table table2 (
"id" number(2)
)
Oracle by default stores the (unquoted) column names in uppercase. Quoted are stored as is.
You can use a DESC table_name to see how the columns are stored.
The following
select id from table1
select iD from table1
select ID from table1
fetch the records, while only
select "id" from table2
will fetch records.
select id from table2
will throw the ORA-00904 : "ID" : invalid identifier error.
You may have inadvertently done the quoting during creation while using tools as established below:
https://community.oracle.com/thread/2349926
Btw: Yes it is possible to insert records for only one column, as long as the other columns do not have a NOT NULL constraint on them.
Actually, I think you may be double quoting the column in the insert statement (not on table creation), although your example is misleading. I guess this because of your error, which says "col1" is invalid, not "COL1" is invalid. Consider this simple test:
SQL> create table mytable
(
col1 varchar2(10)
)
Table created.
SQL> -- incorrect column name, without double quotes
SQL> insert into mytable(col2) values ('abc')
insert into mytable(col2) values ('abc')
Error at line 9

insert into mytable("col1") values ('abc')

ORA-00904: "col1": invalid identifier
The last failed insert attempt is what I think you may be doing:
insert into mytable("col1") values ...
based on the error message:
ORA-00904: "col1": invalid identifier
So the solution would simply be remove the double quoting around the column name in the insert.
It's most probably a syntax error
Desc myTable;
insert into myTable (col1) Values ('val1')
Ensure col1 is a valid column in the table, and you're simply not trying to say 'select the left-most column.
edit: Is it possible to only insert values into certain columns when executing an insert statement in Oracle?
Yes if you want to only insert into certain columns then simply specify it
e.g.
insert into myTable (col1, col2, col6) Values ('val1', 'val2', 'val3');
This will only work if the column itself doesn't have a NOT NULL constraint - in which case it will not allow a value to be enetered (unless again there's a default value).
I've created a sample oracle function to returns the number of records in a table. Here is it
create or replace FUNCTION TEST_COUNT
RETURN NUMBER AS recCount NUMBER;
BEGIN
SELECT COUNT(*) INTO recCount FROM **tableName**;
return recCount;
END TEST_COUNT;
Its' being compiled successfully, but when I called this function in Oracle SQL-Developr using command
SELECT * FROM TABLE (TEST_COUNT());
it threw me the following error.
ORA-22905: cannot access rows from a non-nested table item
22905. 00000 - "cannot access rows from a non-nested table item"
*Cause: attempt to access rows of an item whose type is not known at
parse time or that is not of a nested table type
*Action: use CAST to cast the item to a nested table type
Error at Line: 1 Column: 22
I've followed Oracle error ORA-22905: cannot access rows from a non-nested table item but can't reach the solution. Please suggest what should I do?
Well, you're just calling it wrong. The TABLE() table collection expression is used when the function returns a collection (e.g. from create type x as table of number) that you want to treat as a table so you can join against it, which isn't the case here; you're returning a simple NUMBER.
So just do:
SELECT TEST_COUNT FROM DUAL;
Here's the procedure:
CREATE OR REPLACE PROCEDURE GetBestSellingMovieByTimeId(timeId IN NUMBER) IS
movieName Movie.Name%type;
saleValue Sales.SaleValue%type;
BEGIN
SELECT * INTO movieName, salevalue FROM (
SELECT m.Name, SUM(s.SaleValue) AS TotalSales
FROM Sales s
INNER JOIN Movie m ON s.MovieId = m.MovieId
WHERE s.TimeId = timeId
GROUP BY m.Name ORDER BY TotalSales DESC
) WHERE ROWNUM = 1;
dbms_output.put_line(movieName ||', ' || saleValue);
END;
/
exec GetBestSellingMovieByTimeId(2);
Here's the error:
Error starting at line 190 in command: exec GetBestSellingMovieByTimeId(2)
Error report:
ORA-06502: PL/SQL:numeric or value error: number precision too large

06502. 00000 - "PL/SQL: numeric or value error%s"
*Cause:
*Action:
TimeID is a NUMBER(2,0) FK on a Sales table. Passing the number 2 to the procedure shouldn't be out of range of the NUMBER(2,0) data type.
Why does this procedure think the IN parameter is too large?
Your query selects SUM(s.SaleValue) into a variable saleValue defined as Sales.SaleValue%type.
Normally using the %type syntax is good practice, but only when it matches the assigned value. If Sales.SaleValue is defined with scale and precision it is quite likely that a SUM() of that column will blow the bounds of that definition. As appears to be the case here.
