Question

I have created the following table

CREATE TABLE Customers(
  CustomerID varchar2(9) PRIMARY KEY, 
  Customer_Contact varchar2(40) NOT NULL, 
  Address varchar2(20) NOT NULL,
  Post_Code varchar2(7) NOT NULL, 
  Telephone_Number varchar2(11) NOT NULL)

And I am currently trying to use the INSERT VALUES statement. I have written the following statement

INSERT INTO Customers VALUES(
  501623129, 
  'John Petterson', 
  '-- Singleton Close London', 
  '--- ---', 02082860222)

When I try to run the statement it gives me the following error message.

Error starting at line 4 in command:
INSERT INTO Customers
VALUES(501623129, ‘David Patterson’,
’30 Singleton Close London’, ‘SW17
9JY’, 02082860642) Error report: SQL
Error: ORA-12899: value too large for
column “DJ”.”CUSTOMERS”.”ADDRESS”
(actual: 25, maximum: 20)
12899. 00000 – “value too large for column %s (actual: %s, maximum: %s)”

Answer 1

ORA-12899: value too large for column "DJ"."CUSTOMERS"."ADDRESS" (actual: 25, maximum: 2

Tells you what the error is. Address can hold maximum of 20 characters, you are passing 25 characters.
