How do I create a UDF for MySQL using Delphi?
Does anyone have any code templates?
I want the code template to be integrated in Delphi versions(2007 and upper), so I need these templates to be usable with and without Unicode support.
For starters, Google reveals:
documentation
a forum thread
an example
You need to create a DLL with a few exported functions, as documented.

I have done simple Web API project using SQL server database with code first approach, see here. But I am not getting any helpful complete tutorial which explains how to create Web API using code first approach with MySQL as database. Could you please give me some sample example.
There isn't much difference since both are relational databases. You need to install the corresponding nuget (Install-Package MySql.Data.Entity), update connection string and you should be good to go
Here is detailed example - http://www.asp.net/identity/overview/getting-started/aspnet-identity-using-mysql-storage-with-an-entityframework-mysql-provider
I am new to Node.js and express. Now I am planning to use database for my application. I am used to with mysql. when I google about using database with node.js I found something weird like any-db node-sql or some kind of weird adapters that I need to use to access my normal mysql database. So which one should I use?
What about using https://www.npmjs.org/package/mysql I guess this is the most commonly used module for MySQL.
I need to convert the queries of a MySql-only project to Oracle.
Is there a PL/SQL library that emulates the MySql built-in functions?
Thanks in advance.
I don't know of any library like you're asking for, there are some tools that might help you though. I found this site that tells you the equivalent functions and data types between the two DBMS, and it looks like they have a free online tool you could run your project through which might be the best option if it's not too big.
I'm new to .net mvc 3. I was using PHP Symfony previously.
In this tutorial from the official website, the author used .sdf as example.
http://beta.asp.net/mvc/tutorials/getting-started-with-mvc3/getting-started-with-mvc3-part4-cs
The schema in .sdf was autogenerated according to the Model class file.
My question, is it possible to do the same thing using Mysql?
Thanks :)
This should work (have never used ef code first with mySql) as long as you have the .net connector for MySql.
You can grab it here: http://dev.mysql.com/downloads/connector/net/
You can also try this alternative connector from DevArt: http://www.devart.com/dotconnect/mysql/
* EDIT *
It seems that the DevArt connector will do the trick.
I found the mysql migration toolkit which will migrate the tables.But is there something which will convert the functions as well.
Almost certainly not.
If your functions are in the SQL language only, it should probably be doable. But any of the many other languages supported by PostgreSQL (pl/pgsql, perl, python etc) are completely different, and contain much functionality that's simply not supported on MySQL.
most likely not. the stored procedure and function language differs greatly between postgresql and mysql. such an application would be costly to develop.
There are several data migration tools available on Google to convert database. I use dbload for example.
