What does cursor mean?

Answer 1

In database packages, the term cursor refers to a control structure for the successive traversal (and potential processing) of records in a result set. A cursor is used for processing individual rows returned by the database system for a query. It is necessary because many programming languages suffer from impedance mismatch. Programming languages are often procedural and do not offer any mechanism for manipulating whole result sets at once. Therefore, the rows in a result set must be processed sequentially by the application. In this way, a cursor can be thought of as an iterator over the collection of rows in the result set.

Answer 2

Cursors are database objects used to traverse the results of an SQL query. They point to a certain location within a recordset and allow the operator to move forward (and sometimes backward, depending upon the cursor type) through the results one record at a time. Cursors are often criticized for their high overhead.

Answer 3

In PL/SQL, a cursor is a name assigned to a specific private SQL area for a specific SQL statement. There can be either static cursors, whose SQL statement is determined at compile time, or dynamic cursors, whose SQL statement is determined at runtime.

Answer 4

Cursor is a blinking horizontal or vertical underscore.

Answer 5

Cursor is the mouse that you click things with on your computer!
