bulk_batchsize, bulk_fire_triggers, bulk_keepidentity, bulk_keepnulls, bulk_kilobytes_per_batch, bulk_maxerrors, and rows_per_batch. By using the bulk row set provider, you can load a file into a table column more easily than using conventional DML. Currently, for large objects, you do not need to be limited to text, ntext, or image data types. You can also use varchar (max), nvarchar (max), and

, non-null index, and this unique, non-empty index can only be a single field, not a combined field. Only one full-text index is allowed per table. To create a full-text index on a table, the table must have a unique and non-Null column. You can create full-text indexes on the following types of columns:char,varchar,nchar,nvarchar,text,ntext, image,XML,varbinary , and varbinary (

SQL Server FileStream details, FILESTREAM is a new feature in SQL Server 2008. It allows you to store and enlarge object data in the form of an independent file, instead of storing all data in a data file. In the past, there were two methods to manage files in the business system. One was to save the files to the file
