How do I roll back all or part of a commit to svn?

阅读更多关于 How do I roll back all or part of a commit to svn?

问题 How do I revert all or part of an SVN commit using TortoiseSVN? 回答1: First, you need to identify rather you want to revert back "all changes" of a revision, or just a single file. TortoiseSVN has only the "1 or all" approach; meaning, you can revert back the entire check-in set, or single files: not partial checkins. Entire Changeset So, if reverting back a specific revision (and you want all files in that changeset to be changed), you will want to Right-Click -> TortoiseSVN -> Show log. Find

JMS rollback

阅读更多关于 JMS rollback

问题 I have a process which involves sending a JMS message. The process is part of a transaction. If a later part of the transaction fails, a part that is after a previous part that sent the message, I need to cancel the message. One thought I had was to somehow set on the message that it is not to be picked up for a certain amount of time, and if I need to rollback, then I could go and cancel the message. Not knowing messaging, I do not know if the idea is possible. Or, is there a better idea?

Why does Mercurial only have one level of rollback?

阅读更多关于 Why does Mercurial only have one level of rollback?

问题 I understand the restrictions of rollback and the care required in its use, but I just wondered why there is only one level of rollback. My guess it's a design decision and that the hassle of storing multiple previous transactional states to handle multiple levels of rollback is more trouble than its worth. 回答1: There's only one level of rollback because rollback was never really intended as a feature. Rollback exists, and has it's odd name, because it grew out of mercurial's commit/push/pull

JDBC Transaction control in Sybase

阅读更多关于 JDBC Transaction control in Sybase

Need help in JDBC transaction control mechanism in JAVA. Issue: There are certain stored procedures in our Sybase DB that needs to be run on Unchained mode. Since we are updating our data on two different databases (unfortunately, both Sybase) we need to be able to rollback all our previous transactions, if there is any failure. But running with Unchained Mode (Auto commit - on) is not helping us with the rollbacks as some of the SPs have already committed the transactions. Connection connection = getConnection(); PreparedStatement ps = null; try{ String sql = getQuery(); // SQL Chained Mode

问题 I have migrated my production MySQL schema to Google Cloud SQL. Various modifications have been necessitated to existing Stored Procedures & Scheduled Events, and some new ones deployed. HOWEVER, I have been noticing that where I leave everything working at 6PM, by the time I arrive back at my desk next morning, many (all?)

How to rollback knockout validation errors?

阅读更多关于 How to rollback knockout validation errors?

问题 I use knockout validation 2.0.3 with entity framework 6.0 and get unexpected validation errors. Here is my workflow: Step1: (works as expected) Create a new entity with an add-dialog and try to save the new entity. Validation errors are shown because some properties are missing. This is the wanted behavior. The user cancels the dialog and I call unitofwork.rollback() to undo the creation of the new entity. Step2: Open the edit dialog for an existing entity of the same type. Try to save it as

Rolling back and update command in Sql Server 2000

阅读更多关于 Rolling back and update command in Sql Server 2000

问题 I have used an update command to update the whole table in an Sql Server 2000 database by mistake. I was actually meaning to update just one row. Now all the 2000 rows contain the update. Is there a way to roll back this change? 回答1: Unless you started your update with an explicit transaction, no. However, you might be able to use Log Rescue . I'm not sure though if this can help you in this case. A better option might be to restore a backup to a new database and merge the old and new tables.
