I have installed Oracle 10g in my virtual XP and created a table using
create table reg1 (
fname varchar2(30),
lname varchar2(30),
addr varchar2(30),
mail varchar2(30),
occu varchar2(30),
uname varchar2(30),
passwd varchar2(30)
);
and the table created successfully.But when I am trying to fetch the values by simple query like
select fname, lname
from reg1
where uname="bbb";
I am getting error like
ORA-00904: "bbb": invalid identifier
I cannot understand what I have done wrong here.
Use single quotes.
select fname,lname from reg1 where uname='bbb';
Oracle uses double quotes " in order to identify cased object names. For instance the table "test" is not the same as the table test.
Strings should be enclosed by single quotes, '.
Making your query:
select fname, lname from reg1 where uname = 'bbb';
What's actually happening in your query is Oracle is trying to find the column "bbb" in the table reg1, as this column doesn't exist you get the error thrown.

I am getting an error ORA-00909 in when inserting an object of a superType in an object table. These are the definitions for the objects:
CREATE OR REPLACE TYPE address AS OBJECT (
street VARCHAR(20),
country VARCHAR(20),
province VARCHAR(20),
city VARCHAR2(20),
zipcode VARCHAR(10)
) FINAL;
CREATE OR REPLACE TYPE company AS OBJECT (
CIF VARCHAR2(9),
code VARCHAR2(10),
name VARCHAR2(20),
signUpDate DATE,
email VARCHAR2(20),
adminAddress address
) NOT FINAL;
CREATE OR REPLACE TYPE inCourseCompany UNDER company (
postalAddress address,
numEmployees NUMBER
) FINAL;
And the object table:
CREATE TABLE companies_objtab OF company (PRIMARY KEY CIF) OBJECT IDENTIFIER IS PRIMARY KEY;
I try to insert an object with the following statement:
INSERT INTO companies_objtab VALUES (
company('J12345678','000001','Test Company',TO_DATE(sysdate, 'dd/mm/yyyy hh24:mi:ss'),'',address('','','','',''))
);
and I get error Error
SQL: ORA-00909: invalid number of arguments
00909. 00000 - "invalid number of arguments"
However, when I insert an object of the subtype inCourseCompany it is inserted correctly:
INSERT INTO companies_objtab VALUES (
inCourseCompany('G11111111','','',TO_DATE(sysdate, 'dd/mm/yyyy hh24:mi:ss'),'',address('','','','',''), address('','','','',''), 100)
);
Any hint about what causes the error?
I am using Oracle SQL Developer 4.0.2.15.21 and Oracle Database Express Edition 11g Release 2.
Thank you in advance.
i tried all your statements right as you posted them (copy-paste). Both on 12c and 11gR2. Everything worked, both inserts. The only thing I noticed is that your create table is a bit incorrect. This is the correct one (but this does not explain the error you get). HTH KR
CREATE TABLE companies_objtab OF company (CIF PRIMARY KEY) OBJECT IDENTIFIER IS PRIMARY KEY;
Maybe try dropping the table and creating it again.
I'm trying to make an auto_increment trigger for the IDs of an Oracle database.
After some research, I found a way to write one using a sequence and a before insert trigger.
Problem is, when I execute the trigger, I have the following error :
Parsing failed for:
CREATE OR REPLACE TRIGGER AUTO_INC_PDE_ITINERAIRE
BEFORE INSERT
ON PDE_ITINERAIRE
FOR EACH ROW
BEGIN
SELECT PDE_ITINERAIRE_ID_SEQUENCE.NEXTVAL
INTO
If I use the following command :
select * from SYS.USER_ERRORS where name = 'AUTO_INC_PDE_ITINERAIRE';
It returns the following output :
Line 3 | Pos 10 | PLS-00201: identifier 'NEW.PDE_ITINERAIRE' must be declared
Line 2 | Pos 03 | PL/SQL: SQL statement ignored
Line 4 | Pos 03 | PL/SQL: ORA-00904 invalid identifier
Here is the full query for the trigger :
CREATE OR REPLACE TRIGGER AUTO_INC_PDE_ITINERAIRE
BEFORE INSERT
ON PDE_ITINERAIRE
FOR EACH ROW
BEGIN
SELECT PDE_ITINERAIRE_ID_SEQUENCE.NEXTVAL
INTO :NEW.PDE_ITINERAIRE.ID_PDE_ITINERAIRE
FROM dual;
END;
/
I'm not really used to Oracle's triggers, so could someone help me finding out what is wrong in my trigger ?
Thanks for your time
EDIT
I changed the trigger from your advice
CREATE OR REPLACE TRIGGER AUTO_INC_PDE_ITINERAIRE
BEFORE INSERT
ON PDE_ITINERAIRE
FOR EACH ROW
BEGIN
:NEW.ID_PDE_ITINERAIRE := PDE_ITINERAIRE_ID_SEQUENCE.NEXTVAL;
END;
/
I still have the same error output though.
More informations :
--Oracle is v11.
--TOra 3 is used as IDE.
EDIT 2
Here is the DDL as asked :
CREATE TABLE "GEOMAP"."PDE_ITINERAIRE"
( "ID_PDE_ITINERAIRE" NUMBER(11,0) NOT NULL ENABLE,
"NOM_ITINERAIRE" VARCHAR2(255) NOT NULL ENABLE,
"LONGUEUR" NUMBER(15,4),
"INSEE_DEPART" VARCHAR2(5),
"INSEE_ARRIVEE" VARCHAR2(5),
"TYPE_ITINERAIRE" VARCHAR2(30),
"TYPE_BALISAGE" VARCHAR2(30),
"COULEUR_BALISAGE" VARCHAR2(55),

"COMMUNE_DEPART" VARCHAR2(55),
"COMMUNE_ARRIVEE" VARCHAR2(55),
"FICHIER_TOPO_GUIDE" VARCHAR2(255)
)
:new is a record containing all columns of the trigger's table, so you can't include the table name when referencing it:
:NEW.PDE_ITINERAIRE.ID_PDE_ITINERAIRE should be :NEW.ID_PDE_ITINERAIRE
Additionally, you don't need the select, you can simply assign the value (at least with any supported version of Oracle):
CREATE OR REPLACE TRIGGER AUTO_INC_PDE_ITINERAIRE
BEFORE INSERT
ON PDE_ITINERAIRE
FOR EACH ROW
BEGIN
:NEW.ID_PDE_ITINERAIRE := PDE_ITINERAIRE_ID_SEQUENCE.NEXTVAL;
END;
/
It is fixed !
I finally downloaded Oracle SQL Developer to check my trigger in another IDE, and it proposed me to link a value (NEW) when i executed it.
This last trick did the job.
I assume either Tora does not execute pl/sql properly, or maybe I missed a declaration for :NEW and SQL Developer fixed it.
Thank you for your help.
I have enclosed the table and the insert statement I am working on.
CREATE TABLE EMP (
DRIVER_ID INTEGER NOT NULL
, FNAME VARCHAR(30) NOT NULL
, LNAME VARCHAR(30) NOT NULL
, ADDRESS VARCHAR(50) NOT NULL
, SALARY VARCHAR(50) NOT NULL
, DOB DATE NOT NULL
, SHIFTS VARCHAR2(20) NOT NULL
, SSN CHAR(11) NOT NULL
, PHONE INTEGER NOT NULL
, HIRING_DATE DATE NOT NULL
, EMAIL VARCHAR2(50) NOT NULL
);
When I run this insert statement:
INSERT INTO EMP (DRIVER_ID, FNAME, LNAME, ADDRESS, SALARY, DOB, SHIFTS, SSN, PHONE, HIRING_DATE, EMAIL)
VALUES (SEQ_EMP.NEXTVAL,'Emma', 'Johnson', '123 Main Street', 'DIRECT DEPOSIT', '31 JANUARY,1988', 'MORNING', '579-45-6666', '410-555-1112', '16 DECEMBER,2013', 'ejohnson#fakemail.com');
I get this error message
SQL Error: ORA-01722: invalid number
01722. 00000 - "invalid number"
*Cause: The specified number was invalid.
*Action: Specify a valid number.
Lets look at this logically. The error message is saying "invalid number". Oracle is saying to you "I am expecting a number, but you gave me something that isn't a number".
Looking at the table SQL, you can see that the table has two columns whose type is a number type (actually INTEGER). These are DRIVER_ID and PHONE. (The other columns don't matter now ... because they won't expect a number as the value.)
Now look at the insert SQL, and the values corresponding to those columns.
The value inserted into the DRIVER_ID column comes from SEQ_EMP.NEXTVAL ... which I would assume has type INTEGER. That means, you won't get an error from there.
The value inserted into the PHONE column is '410-555-1112'. But, hey, that isn't a number. Its a string! And besides a (mathematical) number doesn't have hyphen characters embedded in it!
In short, if you are going to store phone numbers with - (or + or space) characters embedded in them, you can't use INTEGER as the column type.
In your table DDL change
PHONE INTEGER NOT NULL
to
PHONE CHAR(12) NOT NULL
as previously mentioned by user Stephen C using CHAR instead of INTEGER.
Also, those DATE fields will have to be converted to CHAR datatypes as well or you'll have to format your INSERT to handle the date format properly. Those fields are:
, DOB DATE NOT NULL
, HIRING_DATE DATE NOT NULL
If you chose to keep the columns as DATEs, then in your insert use (for the above-mentioned columns) the following...
,to_date('31-JANUARY-1988','DD-MONTH-YYYY')
,to_date('16-DECEMBER-2013','DD-MONTH-YYYY')
The above won't give you exactly what you are looking for -- e.g. 16 DECEMBER,2013 -- but it will work and format the date with hyphens -- e.g. 16-DECEMBER-2013. If you need further information on the to_date() function for Oracle for formatting and for other sundry information, please refer to the Oracle docs or search on "Oracle TO_DATE" via your favorite browser.

I am trying to describe a table without using the DESCRIBE command but I want to combine the query with a substitution variable. Assuming I have the following table:
--DROP TABLE customers CASCADE CONSTRAINTS PURGE;
CREATE TABLE customers
( customer_id number(10) NOT NULL,
customer_name varchar2(50) NOT NULL,
city varchar2(50)
);
Following the posts here and here but adding a substitution variable, I have the following:
ACCEPT myv CHAR PROMPT 'Enter a table name: '
SELECT
column_name AS "Name",
nullable AS "Null?",
concat(concat(concat(data_type,'('),data_length),')') AS "Type"
FROM user_tab_columns
WHERE table_name = '&myv';
This returns a blank table with the appropriate column names. It doesn't matter if I entered the table name in the input prompt as CUSTOMERS or customers. However, desc customers yields:
Name Null Type
------------- -------- ------------
CUSTOMER_ID NOT NULL NUMBER(10)
CUSTOMER_NAME NOT NULL VARCHAR2(50)
CITY VARCHAR2(50)
Any idea how I can get substitution variable to work here? Thanks.
I got it to work with a bind variable. Not exactly sure what is going on because #kordirko said the query worked for him as is. Anyway, to get it to work for me (I'm using SQL Developer Version 4.0.3.16), I used bind variable, like so:
SELECT
column_name "Name",
nullable "Null?",
concat(concat(concat(data_type,'('),data_length),')') AS "Type"
FROM user_tab_columns
WHERE table_name = :myv;
I then entered CUSTOMERS into the value field of the Enter Binds window and the query executed fine. If anybody knows why substitution variable failed but bind variable did not, that will certainly add to the discussion.
I'm struggling with an Oracle external table, although I researched the Oracle forums. Still, no success.
Let's suppose I have a simple table
DESCRIBE PRODUCTS
Name Null Type
------------------------------ -------- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
ID NOT NULL NUMBER
NAME VARCHAR2(30)
VALUE NUMBER(5,2)
DEP VARCHAR2(30)
COUNT NUMBER(3)
Then, I created an oracle folder:
CREATE OR REPLACE DIRECTORY ext_prod_dir AS 'c:\';
I save the content of that table in a .lst file
spool c:\products.lst
select p.id || ';' || p.name || ';' || p.value || ';' || p.dep || ';' || p.count FROM products p;
spool off;
P.ID||';'||P.NAME||';'||P.VALUE||';'||P.DEP||';'||P.COUNT
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1;Settlers of Catan;29,95;Toys;3
2;DVD Player;82,97;Electronics;2
3;Red Shirt;12,49;Clothes;3
4;Black Leather Couch;399,99;Furniture;5
5;Oak Cofee Table;223,99;Furniture;5
6;Technodrome;27,99;Toys;4
7;Oh Cereal;3,95;Foods;1
8;Game Console;299,95;Toys;2
9;Video Game;29,95;Toys;3
10;Lawn Chair;34,99;Furniture;11
11;Dog Toy Bone;34,99;Toys;9
12;Heated Blanket;27,95;Toys;8
13;Flux Capacitor;27,95;Toys;7
14;Chocolate Pie;3,14;Foods;7
Then I tried to create the external table:
CREATE TABLE products_ext
(ID NUMBER,
NAME VARCHAR2(30),
VALUE NUMBER(5,2),
DEP VARCHAR2(30),
COUNT NUMBER(3))
ORGANIZATION EXTERNAL
(TYPE oracle_loader DEFAULT DIRECTORY ext_prod_dir
ACCESS PARAMETERS
(RECORDS DELIMITED BY NEWLINE
FIELDS TERMINATED BY ';'
MISSING FIELD VALUES ARE NULL
BADFILE ext_prod_dir:'products.bad_xt'
LOGFILE ext_prod_dir:'products.log_xt'
(ID CHAR(6),
NAME CHAR(30),
VALUE CHAR(8),
DEP CHAR(30),
COUNT CHAR(3)))
location ('products.lst')
) REJECT LIMIT UNLIMITED
So far so good. Then when I select data from the external table, I got:
ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error
KUP-00554: error encontered while parsing access parameters
KUP-01005: syntax error: found "badfile": expecting one of: "column (,reject"
KUP-01007: at line 4 column 7
I tried a huge amount of things, but I got variations on this error. Best thing I accomplished was that I got rid of error, but the table was empty. I would be very much indebted If someone with more experience can point me in the right direction.
BADFILE and LOGFILE are not part of the FIELDS clause. So, move them above the FIELDS TERMINATED.
CREATE TABLE products_ext
(ID NUMBER,
NAME VARCHAR2(30),
VALUE NUMBER(5,2),
DEP VARCHAR2(30),
COUNT NUMBER(3))
ORGANIZATION EXTERNAL
(TYPE oracle_loader DEFAULT DIRECTORY ext_prod_dir
ACCESS PARAMETERS
(RECORDS DELIMITED BY NEWLINE
BADFILE ext_prod_dir:'products.bad_xt'
LOGFILE ext_prod_dir:'products.log_xt'
FIELDS TERMINATED BY ';'
MISSING FIELD VALUES ARE NULL
(ID CHAR(6),
NAME CHAR(30),
VALUE CHAR(8),
DEP CHAR(30),
COUNT CHAR(3)))
LOCATION ('products.lst')
) REJECT LIMIT UNLIMITED
Also, you said when you got rid of the error, the table was empty. Did you check the logfile? If the error is with the VALUE column, then check NLS_NUMERIC_CHARACTERS parameter
in view v$nls_parameters.
select * from v$nls_parameters;
Check if the decimal marker is indeed a comma. If not either update this parameter or change it in the data file.
