## Getting and Installing BDB SQL

The BDB SQL interface comes as a part of the Oracle Berkeley DB download. This can be downloaded from the Oracle Berkeley DB download page.

### On Windows Systems

The BDB SQL interface is automatically built and installed whenever you build or install Berkeley DB for a Windows system. The BDB SQL interface `dll`s and the command line interpreter have names that differ from a standard SQLite distribution as follows:

- `dbsql.exe`

  This is the command line shell. It operates identically to the SQLite sqlite3.exe shell.

- `libdb_sql60.dll`

  This is the library that provides the BDB SQL interface. It is the equivalent of the SQLite `sqlite3.dll` library.

### Note

If you are upgrading an existing BDB SQL installation, and you are upgrading from release 6.1.19 or lower, then see the SQL database upgrade instructions at Updated SQLite Version in the Berkeley DB Installation and Build Guide.

### On Unix

In order to build the BDB SQL interface, you download and build Berkeley DB, configuring it so that the BDB SQL interface is also built. Be aware that it is not built by default. Instead, you need to tell the Berkeley DB `configure` script to also build the BDB SQL interface. For instructions on building the BDB SQL interface, see Building the DB SQL Interface in the Berkeley DB Installation and Build Guide.

The library and application names used when building the BDB SQL interface are different than those used by SQLite. If you want library and command shell names that are consistent with the names used by SQLite, configure the BDB SQL interface build using the compatibility (`--enable-sql_compat`) option.

### Warning

The compatibility option can break other applications on your platform that rely on standard SQLite. This is especially true of Mac OS X, which uses standard SQLite for a number of default applications.

Use the compatibility option only if you know exactly what you are doing.

Unless you built the BDB SQL interface with the compatibility option, libraries and a command line shell are built with the following names:

- dbsql

  This is the command line shell. It operates identically to the SQLite sqlite3 shell.

- `libdb_sql`

  This is the library that provides the BDB SQL interface. It is the equivalent of the SQLite `libsqlite3` library.

### The BDB SQL ADO.NET Interface

You will create the Berkeley DB ADO.NET package. First download `sqlite-netFx-full-source-1.0.106.0.zip` from the SQLite download page https://system.data.sqlite.org/index.html/doc/trunk/www/downloads.wiki.

Then, in the directory `<db>/dist` run this command:

    ./s_sql_drivers -adodotnet \
    		-ado_package /path/to/sqlite-netFx-full-source-1.0.106.0.zip

This will create the package dbsql-adodotnet-18.1.25.zip in the directory `<db>/release`.

#### Prerequisites For Building The ADO.NET Package

- To build the Linq package, you will need to install `Microsoft .NET Framework 3.5 SP1`.
- To build SQLite.Designer, you will need to install the `Microsoft Visual Studio SDK`.

#### Building BDB SQL ADO.NET Interface For Windows

- The package contains Visual Studio solution files:

  - `SQLite.NET.2010.sln` and `SQLite.NET.2012.sln` and `SQLite.NET.2013.sln` and `SQLite.NET.2015.sln`

    For use by with Visual Studio 2010 or 2012 or 2015. Note that these solution files do not build support for Linq or SQLite Designer.

  - `SQLite.NET.2010.MSBuild.sln` and `SQLite.NET.2012.MSBuild.sln` and `SQLite.NET.2013.MSBuild.sln` and `SQLite.NET.2015.MSBuild.sln`

    For use with MSBuild (Microsoft Build Engine). These can also be used with Visual Studio. These solutions exclude SQLite Designer and CompactFramework. By default, these do not build support for Linq.

- Change the current platform target to `ReleaseNativeOnly` choose either `Win32` or `x64` depending on your target platform.
- Build the solution.
