SQL Server Cursor Types - What are Static Cursors in SQL Server | SQL Server Tutorial / TSQL Tutorial

Cursors are the objects those allow us to access the data row by row from result set.

Static Cursor make the copy of result set in memory at time of cursor creation and use that temporary result set to return rows. If any changes are made to original table/s data such as insert, update or delete. The Static cursor does not update stored result set with those changes unless we close the cursor and reopen.

Static Cursors are scrollable (First,Last,Prior,Next,Relative,Absolute)
