technology and computing databasesWhat happens when rows are found using fetch statement?
What happens when rows are found using a FETCH statement 1. It causes the cursor to close 2. It loads the current row values into variables 4. It creates the variables to hold the current row values.
People also ask, what is the purpose of fetch statement?
FETCH Statement. The FETCH statement retrieves rows of data from the result set of a multiple-row query—one row at a time, several rows at a time, or all rows at once—and stores the data in variables, records, or collections.
Thereof, what does fetching a cursor do?
The purpose of using a cursor, in most cases, is to retrieve the rows from your cursor so that some type of operation can be performed on the data. After declaring and opening your cursor, the next step is to use the FETCH statement to fetch rows from your cursor.
Cursors are used when the user needs to update records in a singleton fashion or in a row by row manner, in a database table. The Data that is stored in the Cursor is called the Active Data Set. Oracle DBMS has another predefined area in the main memory Set, within which the cursors are opened.
