I got a warning like this.
Warning: The table 'tbSOTransHeader' has been created but
its maximum row size (9911) exceeds the maximum number of
bytes per row (8060). INSERT or UPDATE of a row in this
table will fail if the resulting row length exceeds 8060
bytes.
My questions are :
1. Is it true max row size is 8060 bytes ?
2. Can we make it larger ?
Thanks.Yes the max amount of actual data in the row can only be 8060. You can
create a table, view etc larger than that with variable length columns as
long as when populated they don't total more than that. NO you can't make
it larger.

All columns of the row have to fit in the page (maximum 8060 bytes),
except for data types text, ntext and image. For those data types, only
16 bytes (for each text/ntext/image column) are needed in the page that
stores the row.
So if the current data does not fit the page, it might be an option to
change large char, nchar, varchar or nvarchar columns to text or ntext.
Hope this helps,

maximum row size exceeds the maximum number of bytes per row (8060
Hi,
I have created a table (say Table1) with few columns, with one of the
columns (say column1) having the data type as Varchar(8000).
Now I run the below query -
BEGIN TRANSACTION
SET QUOTED_IDENTIFIER ON
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE
SET ARITHABORT ON
SET NUMERIC_ROUNDABORT OFF
SET CONCAT_NULL_YIELDS_NULL ON
SET ANSI_NULLS ON
SET ANSI_PADDING ON
SET ANSI_WARNINGS ON
COMMIT
BEGIN TRANSACTION
if not exists (select * from dbo.syscolumns
where id = object_id(N'[dbo].[Table1]')
and OBJECTPROPERTY(id, N'IsUserTable') = 1
and name = 'Column1')
ALTER TABLE dbo.Table1 ADD
Column1 varchar(500) NULL
GO
COMMIT
Now that the column Column1 already exists, the add column statement won't
be executed. But still I get the warning -
"Warning: The table 'Table1' has been created but its maximum row size
(8579) exceeds the maximum number of bytes per row (8060). INSERT or UPDATE
of a row in this table will fail if the resulting row length exceeds 8060
bytes."
My question is, now that the column already exists, the statement itself
won't be executed. Then why do I still get this warning?That has to do with the sequence of query processing and when the warning is generated. Obviously
the warning (the fact that this table will have a row size for which you can exceed the limit in
your data) is generated in a stage which is earlier than when the statements are actually executed.
In other words, the If statement haven't been executed at this stage.

maximum row size exceeds
hi,
I receive following Warning can any one tell me why this is occurs and how
can I eliminate it.
Warning: The table 'Part_Tags' has been created but its maximum row size
(14647) exceeds the maximum number of bytes per row (8060). INSERT or UPDATE
of a row in this table will fail if the resulting row length exceeds 8060
bytes.

Hi Farhan,
Your table definition includes at least one, probably more varchar,
nvarchar of varbinary columns. The theoretic maximum number of bytes in a
row, if all these columns are filled with the maximum length for that
column, is 14,647 bytes. The minimum length (is all varying length columns
are length zero) is below 8,060 bytes.
This is a warning message, there is no error -yet! But as soon as you try
to insert values into the table that make the total length of one row
exceed 8,060 bytes, you will get an error. SQL Server can't handle rows
that exceed 8,060 bytes of data.
Simple repro script to try it for yourself:
-- this will yield a warning similar to the one above,
-- but the table will be created.
create table testit(pk int not null primary key,
vc1 varchar(6000) not null,
vc2 varchar(6000) not null)
go
-- total length < 8,060 - no error
insert testit (pk, vc1, vc2)
select 1, replicate ('x', 3000), replicate ('y', 3000)
go
-- total length > 8,060 - error and insert rejeected
insert testit (pk, vc1, vc2)
select 2, replicate ('x', 6000), replicate ('y', 6000)
go
-- check that only first row was inserted
select * from testit
go
-- growing data beyond 8,060 bytes fails as well
update testit
set vc1 = replicate ('z', 6000)
where pk = 1
go
-- check that row was not updated
select * from testit
go
-- cleanup
drop table testit
go
