• How can I frequently/automatically compare the structure of the same Database?

  - by Pitming

  Does anyone know a tool that automatically compares the structure of a database and gives a report of what was changed? If it can be integrated into a CruiseControl, even better. By structure I also mean functions and stored procedures. Which is probably not clear at first sight ;-) The idea was to integrate that into a cruise control server

• Is order of parameters for database Command object really important?

  - by nawfal

  I was debugging a database operation code and I found that proper UPDATE was never happening though the code never failed as such. This is the code: condb.Open(); OleDbCommand dbcom = new OleDbCommand("UPDATE Word SET word=?,sentence=?,mp3=? WHERE id=? AND exercise_id=?", condb); dbcom.Parameters.AddWithValue("id", wd.ID); dbcom.Parameters.AddWithValue("exercise_id", wd.ExID); dbcom.Parameters.AddWithValue("word", wd.Name); dbcom.Parameters.AddWithValue("sentence", wd.Sentence); dbcom.Parameters.AddWithValue("mp3", wd.Mp3); But after some tweaking this worked: condb.Open(); OleDbCommand dbcom = new OleDbCommand("UPDATE Word SET word=?,sentence=?,mp3=? WHERE id=? AND exercise_id=?", condb); dbcom.Parameters.AddWithValue("word", wd.Name); dbcom.Parameters.AddWithValue("sentence", wd.Sentence); dbcom.Parameters.AddWithValue("mp3", wd.Mp3); dbcom.Parameters.AddWithValue("id", wd.ID); dbcom.Parameters.AddWithValue("exercise_id", wd.ExID); Why is it so important that the parameters in WHERE clause has to be given the last in case of OleDb connection? Having worked with MySQL previously, I could (and usually do) write parameters of WHERE clause first because that's more logical to me. Is parameter order important when querying database in general? Some performance concern or something? Is there a specific order to be maintained in case of other databases like DB2, Sqlite etc? Update: I got rid of ? and included proper names with and without @. The order is really important. In both cases only when WHERE clause parameters was mentioned last, actual update happened. To make matter worse, in complex queries, its hard to know ourselves which order is Access expecting, and in all situations where order is changed, the query doesnt do its intended duty with no warning/error!!

• VS2010 Database Compare. How do you create a *.DBSchema extensioned file?

  - by George

  I'd like to take a snapshot of my database, make some changes and then use the db compare functionality to identify the changes, and who knows, maybe even generate scripts to make the change. I'd like to avoid having to backup the current db and restore it as a separate db just to have a "before" snapshot. I'm guessing I shouldn't have to. Obsviously, I'm clueless about db projects and am looking to be pointed in the right direction. ty!

• With database table design, Is there an advantage of using special naming convention for a Many-to-m

  - by Jian Lin

  Whenever there is a many-to-many relationship, I think there will be immediately a many-to-many table needed (also called a junction table). Is there any advantage of using special naming convention for these tables, as opposed to the other 1 to many tables? Or are there popular special naming conventions used by companies designing database tables?

• How to convert rows of a database query to a XML file?

  - by EASI

  I am developing a Delphi application that needs to pick up the rows from a period of work and convert them to a single XML file in order to upload to a 3rd party web-service. Is there any component or library available to do that? If not, what is the best approach of code to build that DB2XML conversor?

• IOC are at the class level, but what about database conflicts?

  - by mrblah

  With IOC I understand you can substitue implementations out by merely editing a configuration file etc. BUT, what happens when the classes are married to particular database tables and sprocs, you can't just swap out an implementation since the classes/entities are tied to particular tables and stored procedures. Am I right here?

• What's the quickest way to dump & load a MySQL InnoDB database using mysqldump?

  - by Josh Schwartzman

  I would like to create a copy of a database with approximately 40 InnoDB tables and around 1.5GB of data with mysqldump and MySQL 5.1. What are the best parameters (ie: --single-transaction) that will result in the quickest dump and load of the data? As well, when loading the data into the second DB, is it quicker to: 1) pipe the results directly to the second MySQL server instance and use the --compress option or 2) load it from a text file (ie: mysql < my_sql_dump.sql)
