Aliases

DriverFactoryDelegate

alias DriverFactoryDelegate = Driver delegate()

Delegate type to create DDBC driver instance.

Classes

ColumnMetadataItem

class ColumnMetadataItem

Column metadata object to be used in driver implementations

ConnectionPoolDataSourceImpl

class ConnectionPoolDataSourceImpl

Simple connection pool DataSource implementation. When close() is called on connection received from this pool, it will be returned to pool instead of closing. Next getConnection() will just return existing connection from pool, instead of slow connection establishment process.

ConnectionWrapper

class ConnectionWrapper

Wrapper class for connection

DataSourceImpl

class DataSourceImpl

Implementation of simple DataSource: it just holds connection parameters, and can create new Connection by getConnection(). Method close() on such connection will really close connection.

DriverFactory

class DriverFactory

DDBC Driver factory. Can create driver by name or DDBC URL.

ParameterMetaDataImpl

class ParameterMetaDataImpl

parameter set metadate implementation object - to be used in driver implementations

ParameterMetaDataItem

class ParameterMetaDataItem

parameter metadata object - to be used in driver implementations

ResultSetImpl

class ResultSetImpl

Helper implementation of ResultSet - throws Method not implemented for most of methods. Useful for driver implementations

ResultSetMetaDataImpl

class ResultSetMetaDataImpl

Metadata for result set - to be used in driver implementations

Functions

createConnection

Connection createConnection(string url, string[string] params)

Helper function to create DDBC connection, automatically selecting driver based on URL

createConnectionPool

DataSource createConnectionPool(string url, string[string] params, int maxPoolSize, int timeToLive, int waitTimeOut)

Helper function to create connection pool data source, automatically selecting driver based on URL

createDataSource

DataSource createDataSource(string url, string[string] params)

Helper function to create simple DDBC DataSource, automatically selecting driver based on URL

extractDriverNameFromURL

string extractDriverNameFromURL(string url)
