See the above on-line references and the book on reserve for more details. Example 1 : Connecting, quering and displaying results of query. Charles St, Baltimore, MD Example 2 : select fields and place results in variables This is a modification of the example 1, where we select some fields and we split the query results into variables before printing.
You can create and drop tables, insert, update, etc. This page is maintained by Al Bento who can be reached at abento ubmail. Generally, this is done with the following:. For installing DBD::mysql you need to have the libssl header files and the mysql client libs. If you are a user of Cygwin you already know, it contains a nicely running perl 5.
But to install DBD::mysql you have to take a little special action. You'll only need that library and the header files, you don't need any other client parts. Continue to use the Windows binaries. And don't attempt currently to build the MySQL Server part, it is unnecessary, as MySQL AB does an excellent job to deliver optimized binaries for the mainstream operating systems, and it is told, that the server compiled under Cygwin is unstable. Install a MySQL server for testing against.
This prepares the Makefile with the installed Cygwin features. It takes some time, but should finish without error. The --without-server parameter tells configure to only build the clients. Essentially you are now done with this part. If you want, you may try your compiled binaries shortly; for that, do:. The host -h parameter If you have your MySQL server running on some other box, then please substitute ' Some Linux distributions don't come with a gzip library by default.
Running "make" terminates with an error message like. If this is the case for you, install an RPM archive like libz-devel, libgz-devel, zlib-devel or gzlib-devel or something similar. If Perl was compiled with gcc or egcs, but MySQL was compiled with another compiler or on another system, an error message like this is very likely when running "Make test":. Finally, if everything else fails, you are not alone. If you don't find an appropriate posting and reply in the mailing list, please post a question.
Typically a reply will be seen within one or two days. For more information on module installation, please visit the detailed CPAN module installation guide. Chat with us! You may also create client files by compiling from the MySQL source distribution and using configure --without-server If you are using Windows and need to compile from sources which is only the case if you are not using ActivePerl or Strawberry Perl , then you must ensure that the header and library files are installed.
C compiler A C compiler is only required if you install from source. All you need to do is typing in a cmd. CPAN installation Installation of DBD::mysql can be incredibly easy: cpan DBD::mysql Please note that this will only work if the prerequisites are fulfilled, which means you have a C-compiler installed, and you have the development headers and mysql client libraries available on your system.
Manual installation For a manual installation you need to fetch the DBD::mysql source distribution. Enter this subdirectory and type perl Makefile.
PL make make test On Windows you may need to replace "make" with "dmake" or "nmake". If the tests seem to look fine, you may continue with make install If the compilation make or tests fail, you might need to configure some settings.
For Cygwin there is a special section below. Configuration The install script "Makefile. For example, the test database: perl Makefile. Available switches are: testdb Name of the test database, defaults to test. For example, to unpack and build a DBI distribution, use a procedure such as this:. The make test command is important because it verifies that the module is working. Note that when you run that command during the DBD::mysql installation to exercise the interface code, the MySQL server must be running or the test fails.
This ensures that the latest versions of the MySQL client libraries are installed correctly. Initializing the Data Directory. Starting the Server for the First Time.
