With a non-scrollable (or forward-only) cursor, you can FETCH each row at most once, and the cursor automatically moves to the next row. After you fetch the last row, if you fetch again, you will put the cursor after the last row and get the following code: SQLSTATE 02000 (SQLCODE +100).
The FETCH FIRST clause specifies the number of rows to return. Some SQL databases instead have non-standard alternatives, e.g. LIMIT , TOP or ROWNUM . The clauses of a query have a particular order of execution, [ 5 ] which is denoted by the number on the right hand side.
The set of rows the cursor holds is referred to as the active set. [12] A cursor can be explicit or implicit. In a FOR loop, an explicit cursor shall be used if the query will be reused, otherwise an implicit cursor is preferred. If using a cursor inside a loop, use a FETCH is recommended when needing to bulk collect or when needing dynamic SQL.
