Block Cursors

API server cursors are not limited to fetching one row at a time; they can retrieve multiple rows in each fetch. When working with a client/server database, such as Microsoft® SQL Server™, it is more efficient to fetch several rows at a time. The number of rows returned on a fetch is called the rowset size. Cursors that have a rowset size greater than one are called block cursors. In the supported APIs, you can use the block cursors in these ways:
