The cursor behaves properly when doing an INSERT in the loop; but if I try to call a Stored Procedure, the continue Handler 'sets done = 1' and will exit the loop prematurely, after the first record is processed. Any thoughts on how to work around this? Thanks. declare test_cursor cursor for select projectid, projectdesc from tblProjects order by projectdesc; DECLARE CONTINUE HANDLER FOR SQLSTATE '02000' SET done = 1

问题 I use iTerm2 (Build 1.0.0.20130319) and Vim (bin of MacVim Snapshot 66) on top of OS X 10.7.5 as my CLI editing team. In iTerm2 I defined to use a non-blinking vertical bar as a cursor shape.
