I am storing some large strings in my MS SQL server. I want to use TEXT as the data type but am told that this will become obsolete in later versions of MSSQL server so I shouldn't use it. They say I should use NVarchar , but the max characters is 4,000, I need more than 4,000 characters in my strings. Is there a data type I can use for very large strings?

Thanks

You want varchar(MAX) or nvarchar(MAX); they store up to 2G data, which should hold whatever you need to put in the fields.

I tried to enter varchar(max) but get the error:

"Setting for Length must be from 1 to 8000."

leading me to believe that the maximum number of characters is 8000, which is less than I need.

according to me experience, varchar(max) stores 4000 characters, while nvarchar(max) stores 2000 unicode characters.

what version of SQL server are you using?  Varchar(MAX) is new to 2005, but the error you're showing seems to be 2000.

when we nneded to store more that the max value, whatever it is, we split the string into a number of nvarchar(max)  fields. In practice, 4 to 6 such fields was enough  to store whatever we needed.

In SQL 2000, you will be forced to use TEXT if it exceeds 8000 chars.

In SQL 2005, you can use varchar(MAX).

That error message doesn't look exactly like a SQL 2000 msg when you specify MAX.  What software is that msg coming from?
