Does the Pandas DataFrame.to_sql() function require a subsequent commit()?

由 和自甴很熟 提交于 2019-12-07 08:42:55
问题 The documentation for the Pandas function to_sql() available for DataFrame objects (see to_sql() documentation) does not state that a commit() call on the connection is needed (or recommended) to persist the update. Can I safely assume that DataFrame.to_sql('table_name', con) will always automatically commit the changes (like in: con.commit() )? 回答1: Yes, at the end of the day it will be commited automatically. Pandas calls SQLAlchemy method executemany (for SQL Alchemy connections): conn

问题 I try to set the committer date of the latest commit to its author date. Usually this works with git rebase --committer-date-is-author-date HEAD~1 . Unfortunately there is only one commit which means that I have to use --root instead of HEAD~1 but git rebase --committer-date-is-author-date --root does not set the committer date to the author date for some reason. What can I do? 回答1: The bad news Unfortunately git rebase --root uses the interactive rebase code (because the non-interactive code

Restricting Subversion commits if the Jira Issue key is Not in the commit message

由 霸气de小男生 提交于 2019-12-07 06:08:57
问题 I am using SVN-1.7.4 for revision control and atlassian JIRA as the issue tracker for my LAMP website. I want to restrict SVN commit if any of my team member commits without mentioning the Jira Issue key for the same. I am using JIRA standalone and have installed it on my server. Google search gave me Subversion Jira Plugin (https://studio.plugins.atlassian.com/wiki/display/SVN/Subversion+JIRA+plugin) but it can only help me out in tracking the commits that had a JIRA key, not in restricting

Is it necessary to rollback if commit fails?

问题 This seems like a simple enough question, yet I couldn't find any definitive answers specific for MySQL. Look at this: $mysqli->autocommit(false); //Start the transaction $success = true; /* do a bunch of inserts here, which will be rolled back and set $success to false if they fail */ if ($success) { if ($mysqli->commit()) { /* display success message, possibly redirect to another page */ } else { /* display error message */ $mysqli->rollback(); //<----------- Do I need this? } } $mysqli-

问题 If I have a stored procedure that executes another stored procedure several times with different arguments, is it possible to have each of these calls commit independently of the others? In other words, if the first two executions of the nested procedure succeed, but the third one fails, is it possible to preserve the results of the first two executions (and not roll them back)? I have a stored procedure defined something like this in SQL Server 2000: CREATE PROCEDURE toplevel_proc .. AS

SVN Commit without update

由 纵饮孤独 提交于 2019-12-06 19:13:54
问题 My coworker has checked in a few files that I know are wrong. I would like to be able to replace them and commit my local older copies back to the repo. However, SVN doesn't allow me to commit these files without me running update. I am worried that this may cause automatic merge and messe up my local "good" copies. I Is there anyway that I can commit my versions without updating? Non-automatic merge is highly discouraged. What is the alternative? 回答1: Copy your modified files off to the side

Removing a specific commit in the git history with several branches?

由 ≡放荡痞女 提交于 2019-12-06 11:57:46
I know how to remove a specific commit from the git history with git rebase --interactive . My question concerns the more complex case with a history like this: A--X--B--C--D \ E--F where I would like to remove the commit X . The issue is that in this case there are two or more branches with parents ( B in this case) that have X in their history, so a single git rebase -i will not do the trick (at least I do not know how). Is there a simple way to remove X , or do I have to rely on rebasing all branches on their own, possibly with a shell script? Unfortunately Git doesn't make it easy in this
