Class AdbMySqlClientDataSourceInformationService
A service that uses the MySql.Data.MySqlClient ADO.NET provider to supply information about a MySQL™ or MariaDB™ data source behind a connection, such as what character to use for quoting, how to specify parameter markers etc. The information is mainly taken from the "DataSourceInformation" schema collection, and is used to write provider-independent database code.
This class is used when creating AdbProvider instances, use one of the Get() overloads to retrieve the required delegate.
This class can be inherited to overwrite some values, and used to create a custom
MySql.Data.MySqlClient provider, see AdbMySqlClientProvider and
Information for more details.
This class is immutable. This avoids threading issues, since an instance is often accessed by multiple threads. Any user custom provider services should also be immutable for the same reason.
