The UDF of MySQL is a dynamic Connection Library (* Nix is called a shared library) that does not need to set the entry point ). You can call this method to debug a DLL. Now I will introduce a very simple and easy-to-use debugging method. This method directly utilizes Windows APIs, including language-independent, development tool-independent, and project-type-independent. A typical three-way debugging method is not supported. In addition, the debuggin

The User-Defined Function of MySQL is similar to an API. You can use C/C ++ (or C-language) according to certain specifications) compile a set of functions (udfs), compile them into a dynamic link library, and load and unload udfs using the drop function statement. After a UDF is loaded, it can be called like a built-in MySQL function, and the server automatically loads the existing UDF at startup.Copy code

Label:With the release of EF5, a new support for database (SQL Server) UDF is available, depending on the following connection: Https://msdn.microsoft.com/en-us/data/hh859577.aspx, This feature is also inherited by the newly released EF6. The problem is that this UDF seems to be just for tvf-table Value function, but unfortunately, it cannot be imported when trying to import a scalar function. 　　The reason

Introducing Apache Datafu in two parts, this article describes the part of its pig UDF. The code is open source on GitHub (except for the code.) There are also some slides introduction links).Datafu inside are some of the pig's UDFs. Functions that mainly include these aspects:Bags, Geo, hash, linkanalysis, random, sampling, sessions, sets, stats, URLsA package is appropriate for each aspect.I browsed through all the function source code. In fact, the

When the default UDF export fails, you can try to export the UDF manually by using the manual method, as follows:First upload Udf.dll, connect to MySQL, and then follow the steps below to execute the SQL statement.
