Method Details

downcast

public MSSQLConnectOptions downcast(SqlConnectOptions connectOptions)

Description copied from interface: Driver

Downcast the connect options to the specific driver options.

Parameters:

connectOptions - the options to downcast

Returns:

the downcasted options

createConnectionFactory

public ConnectionFactory<MSSQLConnectOptions> createConnectionFactory(Vertx vertx,
 NetClientOptions transportOptions)

Description copied from class: DriverBase

Create a connection factory to the given database.

Specified by:

createConnectionFactory in class DriverBase<MSSQLConnectOptions>

Parameters:

vertx - the Vertx instance

transportOptions - the options to configure the TCP client

Returns:

the connection factory

parseConnectionUri

public MSSQLConnectOptions parseConnectionUri(String uri)

Returns:

true if the driver accepts the connectOptions, false otherwise

acceptsOptions

public boolean acceptsOptions(SqlConnectOptions options)

Returns:

true if the driver accepts the connectOptions, false otherwise

appendQueryPlaceholder

public int appendQueryPlaceholder(StringBuilder queryBuilder,
 int index,
 int current)

Description copied from interface: Driver

Append a parameter placeholder in the query.

The index starts at 0.

• When index == current indicates it is a new parameter and therefore the same * value should be returned.
• When index < current indicates the builder wants to reuse a parameter. The implementation can either return the same value to indicate the parameter can be reused or return the next index to use (which is shall be the current value

Parameters:

queryBuilder - the builder to append to

index - the parameter placeholder index

Returns:

the index at which the parameter placeholder could be added

wrapConnection

public io.vertx.sqlclient.internal.SqlConnectionInternal wrapConnection(io.vertx.core.internal.ContextInternal context,
 ConnectionFactory<MSSQLConnectOptions> factory,
 Connection connection)

Description copied from class: DriverBase

Wrap a given connection into a SqlConnectionInternal. The default implementation wraps with a generic SqlConnectionBase.

Overrides:

wrapConnection in class DriverBase<MSSQLConnectOptions>

Parameters:

context - the connection context

factory - the connection factory

connection - the connection to wrap

Returns:

the wrapped connection
