To iterate properly over a cursor in Teradata SQL, you can use the following steps:
Here is an example of how to iterate over a cursor in Teradata SQL:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
CREATE PROCEDURE iterate_cursor() BEGIN DECLARE cursor_name CURSOR FOR SELECT column1, column2 FROM your_table; OPEN cursor_name; FETCH NEXT FROM cursor_name INTO @variable1, @variable2; WHILE SQLSTATE = 'OK' DO -- Process the row INSERT INTO another_table VALUES (@variable1, @variable2); FETCH NEXT FROM cursor_name INTO @variable1, @variable2; END WHILE; CLOSE cursor_name; END; |
In this example, the cursor fetches rows from your_table
and processes each row by inserting it into another_table
. The loop continues until all rows have been processed, at which point the cursor is closed.
