mysql-native 0.1.7

A native MySQL driver implementation based on Steve Teale's original


To use this package, run the following command in your project's root directory:

Manual usage
Put the following dependency into your project's dependences section:

A Boost-licensed native D client driver for MySQL and MariaDB.

This package attempts to provide composite objects and methods that will allow a wide range of common database operations, but be relatively easy to use. The design is a first attempt to illustrate the structure of a set of modules to cover popular database systems and ODBC.

It has no dependecies on GPL header files or libraries, instead communicating directly with the server via the published client/server protocol.

This version is not by any means comprehensive, and there is still a good deal of work to do. As a general design position it avoids providing wrappers for operations that can be accomplished by simple SQL sommands, unless the command produces a result set. There are some instances of the latter category to provide simple meta-data for the database.

Its primary objects are:

  • Connection: Connection to the server, and querying and setting of server parameters.
  • Command: Handling of SQL requests/queries/commands, with principal methods:
    • execSQL() - plain old SQL query.
    • execSQLTuple() - get a set of values from a select or similar query into a matching tuple of D variables.
    • execPrepared() - execute a prepared statement.
    • execSQLResult() - execute a raw SQL statement and get a complete result set.
    • execSQLSequence() - execute a raw SQL statement and handle the rows one at a time.
    • execPreparedResult() - execute a prepared statement and get a complete result set.
    • execPreparedSequence() - execute a prepared statement and handle the rows one at a time.
    • execFunction() - execute a stored function with D variables as input and output.
    • execProcedure() - execute a stored procedure with D variables as input.
  • ResultSet: A random access range of rows, where a Row is basically an array of variant.
  • ResultSequence: An input range of similar rows.

There are numerous examples of usage in the unittest sections.

This package supports both Phobos sockets and Vibe.d sockets. Vibe.d support is disabled by default, to avoid unnecessary depencency on Vibe.d. To enable Vibe.d support, use:

`-version=Have_vibe_d_core`

If you compile using DUB, and your project uses Vibe.d, then the -version flag above will be included automatically.

This requires MySQL server v4.1.1 or later, or a MariaDB server. Older versions of MySQL server are obsolete, use known-insecure authentication, and are not supported by this package.

See .travis.yml for a list of officially supported D compiler versions.

A note on connections: Normally MySQL clients connect to a server on the same machine via a Unix socket on *nix systems, and through a named pipe on Windows. Neither of these conventions is currently supported. TCP is used for all connections.

See also the old homepage for the original release of this project is. Parts of it are out-of-date, but it still provides a decent overview of the current API. More up-to-date docs with examples are on the way, and are currently a high priority.

Developers - How to run the test suite

This package contains various unittests and integration tests. To run them, run dub test.

The first time you run dub test, it will automatically create a file testConnectionStr.txt in project's base diretory and then exit. This file is deliberately not contained in the source repository because it's specific to your system.

Open the testConnectionStr.txt file and verify the connection settings inside, modifying them as needed, and if necessary, creating a test user and blank test schema in your MySQL database.

The tests will completely clobber anything inside the db schema provided, but they will ONLY modify that one db schema. No other schema will be modified in any way.

After you've configured the connection string, run dub test again and their tests will be compiled and run, first using Phobos sockets, then using Vibe sockets.
