maximum row size.. 8060 bytes ?

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 Limitation

Is the maximum row size per table really limited to
8K bytes? Or is this the internal organization of SQL
data structures. I have imported a legacy table that
wound up having over 100 columns that came in as
NVARCHAR(255) or roughly 25K + in size. Any comments?
ThanksIt will allow you to create the object with the warning something as
The table % has been created but its maximum row size (%) exceeds the
maximum number of bytes per row (8060)
Ex:
create table test_size
(i1 nvarchar(255),
i2 nvarchar(255),
i3 nvarchar(255),
i4 nvarchar(255),
i6 nvarchar(255),
i8 nvarchar(255),
i9 nvarchar(255),
i10 nvarchar(255),
i11 nvarchar(255),
i12 nvarchar(255),
i14 nvarchar(255),
i19 nvarchar(255),
i20 nvarchar(255),
i21 nvarchar(255),
i22 nvarchar(255),
i23 nvarchar(255),
i24 nvarchar(255),
i30 nvarchar(255),
i31 nvarchar(255),
i32 nvarchar(255),
i33 nvarchar(255))
This is because you are using nvarchar datatype which is variable length
data type. Hence it will give you
error at runtime if actual data that you are going to insert goes beyond
8060 bytes. Also point to be noted
that nvarchar table 2 bytes to store a single character.
So SQL server is happy to create a table though a table crosses limit of
8060 bytes per row so far you use
variable data type like varchar/nvarchar but it will throw you an error
while inserting/updating data if actual
row size that a row will occupy goes beyond this limit.

varchar columns, you need to figure in the "soft" factor: the actual limit
is applied to the actual size of content. If you have 100 nvarchar(255)
columns and each column has only 1 character in it, the row size would be
(100 (columns) x 1 (character each column) x 2 (for Nvarchar) + 9 (row
overhead) ) = 209 bytes.

Because the data is not "full" - you will only get an error if you attempt
to put more than 8,060 bytes of *actual data* into the table. I am guessing
that many of your nvarchar(255) columns are NULL or blank.|||Bill,
As mentioned in other posts, SQL server will let you create the table with a
warning about data truncation.While inserting data, the moment a particular
rowsize exceeds 8060, the rest would be truncated and you wouldnt even
know.Means while querying the table, you may be looking at incomplete and
thus false data.

Actually in this case, wouldn't you get the "string or binary data would be
truncated" error message?|||I have five fields each varchar(5000) and about
8 other columns between 50 and 100 bytes each.
so in answer to your question, none is > 8060.

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 job size limited to 3200 bytes

Hi all. I have sql server 2000, and am trying to do a job
(administration/sql server agent/jobs) with sql server enterprise
manager, but the job exceeds 3200 bytes and it tells me that it will
truncate the program.
Is there a way to increase the maximum job size?That is the limit on the script size. One workaround is to create a
procedure & execute this procedure within the job.
