SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'customer_id' cannot be null (SQL: insert into invoices (invoice_no, supplier_id, customer_id, payment_id, issue_date, due_date, total, gst_type, gst, grandtotal, amt_owed, updated_at, created_at) values (XCZ-INV, 1, , 1, , , , , , , , 2017-11-29 18:44:19, 2017-11-29 18:44:19))
You don't sending any costumer_id to your database. But in your database, you say costumer_id can not be null.. You need to change that as "NULL"
Use this, it should works;
UPDATE invoices SET costumer_id = NULL

I have been trying to get this thing working for a few day now (foreign key) and it just don't work, and feel like every solution I used don't work, so i'm asking here to learn what was the problem and how to fix it
Table creation :
CREATE TABLE CUSTOMER
(
Customer_ID varchar(255) NOT NULL,
Customer_Name varchar(50),
Customer_Gender varchar(10),
Customer_DOB varchar(20) ,
CONSTRAINT CUSTOMER_PK PRIMARY KEY(Customer_ID)
) ;
CREATE TABLE PAYMENT
(
Payment_ID varchar(255) NOT NULL,
Cust_ID varchar(255),
Payment_Method varchar(30),
Payment_Date varchar(20),
Payment_Total NUMBER(10,2) ,
CONSTRAINT PAYMENT_PK PRIMARY KEY(Payment_ID),
CONSTRAINT fk_customer FOREIGN KEY(Cust_ID) REFERENCES CUSTOMER(Customer_ID)
) ;
Inserting values :
INSERT INTO CUSTOMER VALUES ('1277','Jenny','Female', ( TO_Date ( '03/04/1988' , 'DD/MM/yyyy')));
INSERT INTO CUSTOMER VALUES ('3423','Bryan','Male', ( TO_Date ( '15/06/1990' , 'DD/MM/YYYY')));
INSERT INTO CUSTOMER VALUES ('4385','Mohd Shafik','Male',( TO_Date ( '20/08/1993' , 'DD/MM/YYYY')));
INSERT INTO PAYMENT VALUES ('24P','Cash', ( TO_Date ( '11/02/2022' , 'DD/MM/YYYY')),24.50);
INSERT INTO PAYMENT VALUES ('09p','Online Transfer', ( TO_Date ( '08/04/2022' , 'DD/MM/YYYY')),25.00);
INSERT INTO PAYMENT VALUES ('10P','Cash', ( TO_Date ( '08/07/2022' , 'DD/MM/YYYY')),22.50);
The foreign keys are now working , but just for life of me can't figure out why the it spits out ORA-00947: not enough values and
ORA-01400: cannot insert NULL into ("SQL_GUUNNGDQAOXJVYPBKNMILVXJR"."PAYMENT"."PAYMENT_ID") ORA-06512: at "SYS.DBMS_SQL", line 1721
Also, Please explain to me how references works, i read a few places but they use words that just confuse me. Please and thank you!
Use DATE data types to store date values (and VARCHAR2 instead of VARCHAR) in your tables:
CREATE TABLE CUSTOMER(
Customer_ID varchar2(255) NOT NULL,
Customer_Name varchar2(50),
Customer_Gender varchar2(10),
Customer_DOB DATE,
CONSTRAINT CUSTOMER_PK PRIMARY KEY(Customer_ID)
);
CREATE TABLE PAYMENT(
Payment_ID varchar2(255) NOT NULL,
Cust_ID varchar2(255),
Payment_Method varchar2(30),
Payment_Date DATE,
Payment_Total NUMBER(10,2) ,
CONSTRAINT PAYMENT_PK PRIMARY KEY(Payment_ID),
CONSTRAINT fk_customer FOREIGN KEY(Cust_ID) REFERENCES CUSTOMER(Customer_ID)
);
Then name the columns in your INSERT statements:
INSERT INTO CUSTOMER (
customer_id, customer_name, customer_gender, customer_dob
) VALUES (
'1277','Jenny','Female', TO_Date('03/04/1988', 'DD/MM/yyyy')
);
INSERT INTO CUSTOMER (
customer_id, customer_name, customer_gender, customer_dob
) VALUES (
'3423','Bryan','Male', TO_Date('15/06/1990', 'DD/MM/YYYY')
);
INSERT INTO CUSTOMER (
customer_id, customer_name, customer_gender, customer_dob
) VALUES (
'4385','Mohd Shafik','Male', TO_Date('20/08/1993' , 'DD/MM/YYYY')
);
Then for the PAYMENT inserts, you have 5 columns in the table but only 4 pieces of data being inserted:
INSERT INTO PAYMENT (
payment_id, payment_method, payment_date, payment_total
) VALUES (
'24P','Cash', TO_Date('11/02/2022', 'DD/MM/YYYY'),24.50
);
INSERT INTO PAYMENT (
payment_id, payment_method, payment_date, payment_total
) VALUES (
'09p','Online Transfer', TO_Date( '08/04/2022' , 'DD/MM/YYYY'),25.00
);
INSERT INTO PAYMENT (
payment_id, payment_method, payment_date, payment_total
) VALUES (
'10P','Cash', TO_Date('08/07/2022', 'DD/MM/YYYY'),22.50
);
You have not provided a Cust_ID value so it will default to NULL in those rows.
If you want to provide a Cust_ID then add it to the statement:
INSERT INTO PAYMENT (
payment_id, cust_id, payment_method, payment_date, payment_total
) VALUES (
'ABC', '1277', 'Cash', TO_Date('08/07/2022', 'DD/MM/YYYY'),22.50
);

SELECT 'tf1bb2ve533093822','standard van', 79885, 'ford' FROM DUAL;
Note:
You had an extra . after the table name in the DDL statement and spaces in the mileage (18 325 and 79 885) which need removing and you needed an INTO keyword before the second insert.
It is also useful to name your constraints (then you can easily determine which constraint has been violated in later statements).
I'm stuck and can't figure out how to add the condition to the CHECK constraint in oracle...
Basically I have a table with the following structure:
CREATE TABLE TEST_TBL
(
COL_1 VARCHAR2(100) NOT NULL,
COL_2 VARCHAR2(100) NOT NULL,
COL_3 VARCHAR2(100) NOT NULL,
COL_4 VARCHAR2(100) NOT NULL,
DEF_COL CHAR(1) DEFAULT 'Y',
CONSTRAINT def_check_const
CHECK (???????)
);
There may be multiple values in this table, however I require that only 'Y' or 'N' can be entered in the DEF_COL column. Also i want to add a constraint to restrict the number of 'Y' in the DEF_COL column to only one. There may be multiple 'N' entries allowed for DEF_COL column. Please could someone guide me as to what must be done to add the constraint in the check section of the create table query?
Thanks in advance....
Oracle Setup:
CREATE TABLE TEST_TBL(
COL_1 VARCHAR2(100) NOT NULL,
COL_2 VARCHAR2(100) NOT NULL,
COL_3 VARCHAR2(100) NOT NULL,
COL_4 VARCHAR2(100) NOT NULL,
DEF_COL CHAR(1) DEFAULT 'Y'
CONSTRAINT def_check_const
CHECK ( DEF_COL IN ('Y', 'N' ) )
);
CREATE UNIQUE INDEX def_col_only_one_y__U
ON TEST_TBL( CASE DEF_COL WHEN 'Y' THEN 'Y' END );
Insert a row:
INSERT INTO TEST_TBL VALUES ( 'A1', 'A2', 'A3', 'A4', 'Y' );
1 rows inserted.
Insert a second column with DEF_COL = 'Y':
INSERT INTO TEST_TBL VALUES ( 'B1', 'B2', 'B3', 'B4', 'Y' )
Error report -
SQL Error: ORA-00001: unique constraint (TEST.DEF_COL_ONLY_ONE_Y__U) violated
00001. 00000 - "unique constraint (%s.%s) violated"
*Cause: An UPDATE or INSERT statement attempted to insert a duplicate key.
For Trusted Oracle configured in DBMS MAC mode, you may see
this message if a duplicate entry exists at a different level.
*Action: Either remove the unique restriction or do not insert the key.
Update:
To have only one Y for each unique combination of 3 columns then try:
CREATE UNIQUE INDEX C1_2_3__def_col_only_one_y__U
ON TEST_TBL( COL1, COL2, COL3, CASE DEF_COL WHEN 'Y' THEN 'Y' END );
SCHEMA 1
I have table transaction table
create table TXN_HEADER
(
txn_id NUMBER(10) not null,
txn_Date date
product_id NUMBER(10),
company_id NUMBER(10),
dealer_id NUMBER(10),
tran_amt number(10,2)
)
The above table having foreign key references to product.product_id and company.company_id.
This table having 5m rows
SCHEMA 2
create table TXN_HEADER_REPORTS
(
txn_id NUMBER(10) not null,
txn_Date date
product_id NUMBER(10),
company_id NUMBER(10),
dealer_id NUMBER(10),
tran_amt number(10,2)
)
here also we have the same constraints , having foreign key references to product.product_id and company.company_id.
in schema 2 we are trying to insert all the rows from schemea 1 to schema 2 in one shot, like this
begin
insert into TXN_HEADER_REPORTS (
txn_id, txn_Date ,product_id,company_id , dealer_id , tran_amt)
select
txn_id, txn_Date ,product_id,company_id , dealer_id , tran_amt
from schema1.TXN_HEADER;
commit;
exception
when others then
< ... procedure to log the errors >
end;
now we are trying to execute the above procedure , and it failed due to foreign key constraint of one rows. But entire my transaction rollback. Actually i dont want to use cursor to process the rows one by one , at it takes long time. So i used to "insert into .. SElect from " but due to constraints of 1 row all my transaction not moved to schema2.txn_Extract_hdr.
Is there any way to trap only that failed and to process the other rows without terminating
Please advice ..
You can create an error log table, and then use a single insert:
exec dbms_errlog.create_error_log(dml_table_name => 'TXN_HEADER_REPORTS');
insert into TXN_HEADER_REPORTS ( txn_id, txn_Date ,product_id,company_id ,
dealer_id , tran_amt)
select txn_id, txn_Date ,product_id,company_id , dealer_id , tran_amt
from schema1.TXN_HEADER
log errors into ERR$_TXN_HEADER_REPORTS reject limit unlimited;
Any rows that can't inserted will be recorded in the ERR table. Note that this is plain SQL, it doesn't need to be in a PL/SQL block.
Read more in the documentation.
I don't understand your constraint.
Does your insert fail because the product_id and company_id don't exists in schema2?
In that case, it may be better to insert the missing company and product records before you insert records into TXN_HEADER_REPORTS of schema2.
insert into company com_sch2
(col1, col2, col2,...)
select col1, col2, col3, ...
from schema1.company com_sch1
where not exists (select 'x'
from company com2
where com2.company_id = com_sch1.company_id);
And the seem for the product table.
