Re: link under Win32 for udf
Thank you very much for your answer. I am sorry to have misled you by my incomplete question. I asked you about build MySql from src earlier and that message was mistakingly associated with the previous one. I meant building not dll containing UDF, but MYSQL itself. I built it as specified in http://www.mysql.com/doc/en/Windows_source_build.html. However it doesn't find dll with UDF. One should run a script to create Makefile with a flag --with-mysqld-ldflags=-rdynamic for Unix. ... when building MYSQL under Win32, MYSQL should be built with enabled UDF. Nick here instructions how to use udf_example.cc on VC++. Assuming that the user has VC++ 6.0, the Windows MySQL source and running a MySQL server with the same version. - Open the mysqld.dsw workspace. - Add New project to the workspace - Project name: udf_example - Select Win32 Dynamic-Link Library - Click OK - Select An Empty DLL project - Click Finish - Click OK - Right click over the new project and select Add Files to Project - Add \sql\udf_example.cpp - Type Ctrl+N for to create a new file. - Select text type - File name: udf_example.def - Edit the above file with the below contents: LIBRARY UDF_EXAMPLE DESCRIPTION 'Example Using UDF with VC++' VERSION 1.0 EXPORTS metaphon myfunc_double myfunc_int avgcost - Right Click the udf_example project and select Settings - Click the C/C++ tab - Select General in the Category Combo - Add the macro HAVE_DLOPEN to the PreProcessor definition - Select Preprocessor in the Category Combo - Add the include path to the text box: Additional Include directories e.g: ../include - Click Menu Project/Dependencies and add the strings library - Press F7 for to build the DLL.

Re: Unlock tables when process has killed.
Thanks, Miguel.
I understand.
If after killing a process, program of this process come to the end
incorrectly (fail), then the table remains locked.
Something like have than mysql.exe after killing process don't touch. Other
mysql.exe will wait for this process killed, but it doesn't kill while
mysql.exe executed.
Sorry for my English.
