Remarks

A provider is described by its DbMetadata: the connection, command and parameter types to instantiate, the parameter prefix, and so on. Descriptions come from the container — the drivers Quartz ships descriptions for, plus anything the application registered — rather than from process-wide state, so two containers in one process no longer have to agree on what a provider name means.

This is the provider that constructs the driver's objects, and so the one that needs their types. When the description resolved them from a name — which is what naming a built-in driver does — a trimmed application has no guarantee they survived, and the constructor below is where that shows up. A provider that needs no type at all is the one built over a DbProviderFactory, or the data source path.

Constructors

DbProvider(DbMetadata, string)

Initializes a new instance of the DbProvider class from an already-resolved description of the driver.

public DbProvider(DbMetadata metadata, string connectionString)

Parameters

metadata DbMetadata

The metadata describing the ADO.NET driver.

connectionString string

The connection string.

DbProvider(string, string)

Initializes a new instance of the DbProvider class, described by one of the drivers Quartz ships a description for.

public DbProvider(string dbProviderName, string connectionString)

Parameters

dbProviderName string

Name of the db provider.

connectionString string

The connection string.

Remarks

This overload has no container to ask, so it sees only the built-in descriptions. A driver Quartz knows nothing about is described through the container instead — see the metadata callback on UseGenericDatabase — which is also how a built-in description is replaced.

Properties

ConnectionString

Connection string used to create connections. Arrives through the implementation's constructor; a provider is fully usable once constructed.

public string ConnectionString { get; }

Property Value

string

Metadata

The database metadata for the provider.

public DbMetadata Metadata { get; }

Property Value

DbMetadata

Methods

CreateCommand()

Returns a new command object for executing SQL statements/Stored Procedures against the database.

public virtual DbCommand CreateCommand()

Returns

DbCommand

An new IDbCommand

CreateConnection()

Returns a new connection object to communicate with the database.

public virtual DbConnection CreateConnection()

Returns

DbConnection

A new IDbConnection

Shutdown()

Shutdowns this instance.

public virtual void Shutdown()
