[sql-server] SQL Server Error : String or binary data would be truncated

My table :

log_id                 bigint
old_value                  xml
new_value                  xml
module                 varchar(50)
reference_id           bigint
[transaction]          varchar(100)
transaction_status         varchar(10)
stack_trace                ntext
modified_on                datetime
modified_by                bigint

Insert Query :

INSERT INTO [dbo].[audit_log]
           ([old_value],[new_value],[module],[reference_id],[transaction]
           ,[transaction_status],[stack_trace],[modified_on],[modified_by])
     VALUES
            ('asdf','asdf','Subscriber',4,'_transaction',
            '_transaction_status','_stack_trace',getdate(),555)

Error :

Msg 8152, Level 16, State 14, Line 1
String or binary data would be truncated.
The statement has been terminated.

Why is that ???

This question is related to sql-server sql-server-2005

The answer is


this type of error generally occurs when you have to put characters or values more than that you have specified in Database table like in this case: you specify transaction_status varchar(10) but you actually trying to store
_transaction_status which contain 19 characters. that's why you faced this type of error in this code..


This error is usually encountered when inserting a record in a table where one of the columns is a VARCHAR or CHAR data type and the length of the value being inserted is longer than the length of the column.

I am not satisfied how Microsoft decided to inform with this "dry" response message, without any point of where to look for the answer.
