8000 char Row limit

is the 8000 char row limit only an issue in standard
edition? If I upgrade to enterprise edition will I not
have this problem? Thanks.
It has nothing to do with the edition; it is a storage / engine limitation.
What exactly are you trying to do? Are you aware of the reasons for the
limit?

|||The actual row limit is 8060, and the max char/varchar column size is 8000
bytes.

|||This sql server is running our Microsoft CRM database. I
am trying to create some custom attributes. When I try to
create one it says that I am at the 8000 char row limit.
I can not delete any attributes. Is there not a way
around this? Thanks for your replys.

|||The error message is just a warning. You can go ahead and create a table
that is wider, just don't expect to use it all. For example:
CREATE TABLE dbo.blat
(
bar1 VARCHAR(5000),
bar2 VARCHAR(5000)
)
GO
Warning: The table 'blat' has been created but its maximum row size (10025)
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.
As the message states, the table was still created. However, populating it
with data will be more challenging. These work fine:
INSERT blat SELECT 'a', 'b'
INSERT blat SELECT REPLICATE('a', 5000), 'b'
INSERT blat SELECT 'a', REPLICATE('b', 5000)
But when you try and send more than 8060 bytes, you will have problems, e.g.
INSERT blat SELECT
REPLICATE('a', 5000), REPLICATE('b', 5000)
You get:
Server: Msg 511, Level 16, State 1, Line 1
Cannot create a row of size 10013 which is greater than the allowable
maximum of 8060.
The statement has been terminated.
What I recommend is storing any larger attributes in a separate table and
use relationships for data integrity.
Maybe you can show the code that represents "when I try to create one" and
the ACTUAL error message you receive, not your casual interpretation...

|||I am not trying to manually create this table. The table
is created upon the installation of CRM and I am trying to
add an attribute to it within microsoft CRM. In CRM i get
the following error:
An error occurred during the addition of the new field.
The addition failed. For more information, see the event
log.
Event log error:
1.
dmLog: Failed to add new Picklist attribute (CFPcatagory)
to Account entity.
2.
dmLog: New size of the attribute ({53B8A5DA-324C-4926-9F57-
B21C02C1E8C7}) exceeds the SQL Server row limit of 8000
bytes.
I dont know if you are familiar with CRM deployment
manager, there is a section to create mappings, which
might be the same as the relationships as your talking
about. It will not let me modify any existing attribute,
even the ones that I have created. I cant delete an
attribute either.
Thanks again for your help.

|||This limitation will be removed in Yukon. You will be able to do the
following (for example):
create table t1 (c1 varchar (5000), c2 varchar (5000))
go
insert into t1 values (replicate ('a', 5000), replicate ('b', 5000))
go
with no problems.

|||Billy,
As stated, it is only a warning. How much of the 8060 char limit is being
used by the unmodified table?
If you have 16 bytes left, you can assign the new attribute to a text or
ntext column, and that will fit. Of course, you then have to deal with the
issues that arise from using text columns.
You can create an attribute table of nothing more than an identity or guid
column and the attribute and then just store the identity (4 bytes) or
rowguid (16 bytes) in your table.
You might also run statistics on the actual size of data being stored vs the
field size for all fields in the table. Knowing this will give you an idea
of how much space you can "safely" assign to the new attribute. The caveat
here is that you will have to check the length of everything on inserts and
updates.
Regards,
John

|||sounds like one for the CRM group if there is one - being unable to remove
user-defined attributes sounds like a design flaw
