SQL Error: ORA-12899: value too large for column

问题:

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)"

回答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.

回答2:

Here is an example:

CREATE TABLE Customers(CustomerID  VARCHAR2(9 BYTE), ... 

or

CREATE TABLE Customers(CustomerID  VARCHAR2(9 CHAR), ...

This answer still comes up high in the list for ORA-12899 and lot of non helpful comments above, even if they are old. The most helpful comment was #4 for any professional trying to find out why they are getting this when loading data.

Some characters are more than 1 byte in length, especially true on SQL Server. And what might fit in a varchar(20) in SQLServer won't fit into a similar varchar2(20) in Oracle.

I ran across this error yesterday with SSIS loading an Oracle database with the Attunity drivers and thought I would save folks some time.
