   • Requirements for mysql database in node.js server

     Top Answer

     Answered Jul 01, 2014 · 2 votes

     To install the MySQL node.js driver:

     If you run just npm install mysql, you need to be in the same directory that your run your server. I would advise to do it as in one of the following examples:

     For global installation:

     npm install -g mysql-

     For local installation:

     1- Add it to your package.json in the dependencies:

     "dependencies": { "mysql": "~2.3.2", ...

     2- run npm install

     Note that for connections to happen you will also need to be running the mysql server (which is node independent)

     To install MySQL server:

     There are a bunch of tutorials out there that explain this, and it is a bit dependent on operative system. Just go to google and search for how to install mysql server [Ubuntu|MacOSX|Windows]. But in a sentence: you have to go to http://www.mysql.com/downloads/ and install it.

   • Requirements for using an SQL database in a program

     Top Answer

     Answered Feb 22, 2010 · 2 votes

     If the database needs to be local there could be some requirements. It depends on what edition of SQL Server you plan on running. SQL Server Express Edition (this replaces MSDE) is free but will need to be installed. Your other major option is SQL Server Compact Edition (SQL CE). That version does not require an install but it does have reduced capabilities. Check out this for a better understanding of the different types of SQL Server. There are some links there to more information on the specific editions.

   • database transaction rollback processing in PHP

     Top Answer

     Answered Mar 02, 2010 · 5 votes

     When using transactions, the basic idea is that nothing will actually get permanently written to the database until commit is called.

     A couple of situations :

     • If you : begin a transactionexecute some queriesrollbackThen the queries are rolled-back ; which means their result is not written to the database.
     • If you : begin a transactionexecute some queriesdisconnect (which happens if your PHP script ends -- for instance, because of a Fatal Error or a die)
     • Then, the queries are not commited -- which means they are not written to the database ; which means it's the same as if there had been a rollback.

     To makes things simple : starting from the begin transaction, nothing gets permanently written to the database, until you send a commit. If there is no commit... Nothing is permanently written, and when your PHP script disconnects from the DB, the DB "cancels" what that PHP script did not commit.

     Of course, this is exactly the same if you are using something else than PHP to connect to your database -- like the command-line MySQL client, for instance.

     All 3 solutions will work, and only bring a subset of the results into memory.

     Iterating via the cursor, Proposed solution #3, will work the same as Proposed Solution #2, if you pass a name to the cursor. Iterating over the cursor will fetch itersize records (default is 2000).

     Solutions #2 and #3 will be much quicker than #1, because there is much less of a connection overhead.
