Strong Liu commented on HHH-3965:
---------------------------------

by HHH-5725, now, SqlServerDialect now should be only applied to Sql Server 2000, if you're using 2005, then should using SQLServer2005Dialect, the fix of this issue will go into SQLServer2005Dialect too

> I have an entity which needs to store long text field (at least 30,000 characters).
> I use SQL Server 2005 as back-end database.
> SQL Server varchar support up-to 8,000 characters in length of a field, or the reserved word MAX which indicate that the field length will be 2^31-1.
> I think that the class SQLServerDialect should be changed to have the following line in it's ctor:
> registerColumnType( Types.VARCHAR, 8001, "varchar(MAX)" );
> this way, all String fields with length above 8000 will have varchar(MAX) as column type.
