Bulk-Fetching from a Cursor

8,127 Recognized Expert Expert
We can fetch from a cursor into one or more collections:

Expand|Select|Wrap|Line Numbers
  2. TYPE NameList IS TABLE OF employees.last_name%TYPE;
  3. TYPE SalList IS TABLE OF employees.salary%TYPE;
  4. CURSOR c1 IS SELECT last_name, salary FROM employees WHERE salary > 10000;
  5. names NameList;
  6. sals SalList;
  8. recs RecList;
  9. PROCEDURE print_results IS
  10. BEGIN
  11. dbms_output.put_line('Results:');
  12. IF names IS NULL OR names.COUNT = 0 THEN
  13. RETURN; -- Don't print anything if collections are empty.
  14. END IF;
  15. FOR i IN names.FIRST .. names.LAST
  16. LOOP
  17. dbms_output.put_line(' Employee ' || names(i) || ': $' ||
  18. sals(i));
  19. END LOOP;
  20. END;
  21. BEGIN
  22. dbms_output.put_line('--- Processing all results at once ---');
  23. OPEN c1;
  24. FETCH c1 BULK COLLECT INTO names, sals;
  25. CLOSE c1;
  26. print_results;
  27. dbms_output.put_line('--- Processing 7 rows at a time ---');
  28. OPEN c1;
  29. LOOP
  30. --LIMIT restricts the number of records to fetch.
  31. FETCH c1 BULK COLLECT INTO names, sals LIMIT 7;
  33. print_results;
  34. END LOOP;
  35. -- Loop exits when fewer than 7 rows are fetched. Have to
  36. -- process the last few. Need extra checking inside PRINT_RESULTS
  37. -- in case it is called when the collection is empty.
  38. print_results;
  39. CLOSE c1;
  40. dbms_output.put_line('--- Fetching records rather than columns ---');
  41. OPEN c1;
  43. FOR i IN recs.FIRST .. recs.LAST
  44. LOOP
  45. -- Now all the columns from the result set come from a single record.
  46. dbms_output.put_line(' Employee ' || recs(i).last_name || ': $'
  47. || recs(i).salary);
  48. END LOOP;
  49. END;

Hello, I am trying to load a simple tab-delimited data file to SQL Server. I created a format file to go with it, since the data file differs from the destination table in number of columns.

So, I proceeded with the Enterprise Manager to grant myself those roles. However, I could not find sysadmin or...

Right now I develop an application to retrieve over 30,000 records from a binary file and then load them into a SQL Server DB. So far I load those records one by one, but the performance is very poor: it takes more than 6 hours to finish the loading. So could I make use of the bulk-insert mechanism of SQL Server to reduce the loading time in C# codes? or other performance improvement solutions?

We have sp's in place that do BULK INSERTS from txt files into the tables. This works fine, however they have asked us to add a field that identifies accounting ctr. The only thing that identifies accounting ctr is the last three letters of the text file being used for the BULK INSERT. How would you suggest that I do this? Is there a way to add a default value to the .fmt or schema files for the text fields, or in the BULK INSERT...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
