About Transacations BEgin, Commit, Auto-commit.

What do you mean by some systems don't have autocommit turned on and thus we need to begin and commit after each statement. I remember you talked ABOUT IT IN the transactions section. The problem is I don't get why you would need to begin if you did not have to turn off autocommit cause it doesn't exist.

Not all databases have an autocommit feature that you can turn on and off.

This information only applies to those which do. And if it is turned off, any changes you make will not be permanent until you give the commit command.

So then, if the db doesn't autocommit, then we need to:




for each statement?

or would we just commit at the end

statement statement

I can't speak for all databases, but ones I have used personally allow you to perform multiple statements with one commit at the end.
