table_name can be a simple table name or a full path name. A table name is preferred for portability to other SQL data sources.
The Where Current Of cursor_name clause can be used only by developers coding directly to the ODBC API. It causes the row at which
cursor_name is positioned to be deleted. This is called a "positioned delete." You must first execute a Select...For Update statement with a named cursor and fetch the row to be deleted.
Each Delete statement removes every record that meets the conditions in the Where clause. In this case, every record having the employee ID E10001 is deleted. Because employee IDs are unique in the employee table, at most, one record is deleted.
