SQL 2K:

I changed datatype of ItemDescription nvarchar to varchar (4000). I m using Inner Join Query Where I have to use
"Select t1.Itemdesction , t2.ItemDescription, t3.ItemDescription from ItemMaster....".

 I am getting error

" Cannot sort a row of size 8096, which is greater than the allowable maximum of 8094"

I tried to change datatype back to nvarchar , its giving error while saving :

'ItemMaster' table
- Unable to modify table.  
ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]Cannot create a row of size 9517 which is greater than the allowable maximum of 8060.
[Microsoft][ODBC SQL Server Driver][SQL Server]The statement has been terminated.

change it to text data type


It looks like you have too much data in the row already.
What is the total size of the other columns?
SQL Server will allow you to define a column of a variable length size, that
could end up leading to errors on insert or update.

For example, you could create a table that has 10 varchar(8000) columns,
with no error.
But if you tried to insert 8000 bytes into 2 of those columns, you would get
an error.

The only way in SQL 2000 to have more than 8060 bytes in a row is to use the
text data type.
