SQLite and Standard SQL
+0 Vote Up -0Vote Down

I'm going to need to use SQLite syntax for a project that I'm involved with, and predictably I wonder: how standard is it? The SQLite folks themselves make modest claims to support most of the features with a special focus on SQL-92, but (a) I like to do my own counting (b) there's no official standard named SQL-92 because it was superseded 17 years ago.

By ignoring SQL-92 claims I eschew use of the NIST test suite. I'll be far less strict and more arbitrary: I'll go through SQL:2011's "Feature taxonomy and definition for mandatory features". For each feature in that list, I'll …

Cédric Bruderer: Why is varchar(255) not varchar(255)?
+0 Vote Up -0Vote Down

Recently I was working on a clients question and stumbled over an issue with replication and mixed character sets. The client asked, wether it is possible to replicate data to a table on a MySQL slave, where one column had a different character set, than the column in the same table on the master.

 

I set up two servers with identical table definitions and changed the character set on one column on the slave from latin1 to utf8.

 

Master:

CREATE TABLE `test` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `data` varchar(255) DEFAULT NULL,
  `ts` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON …

Migrate from MS SQL Server to MySQL
+0 Vote Up -0Vote Down

In this blog series, I will share my experiences as I migrate commercial databases (i.e., Microsoft SQL or Oracle) to open source (MySQL). More specifically, we will look at how you can migrate from MS SQL Server to MySQL.

  1. MySQL Workbench (opensource)
  2. Amazon DMS (cloud tool)
  3. Ispirer MnMTK 2015 (commercial tool)
