begin()

void Connection::begin ( )

inlineoverridevirtual

Begin a SQL transaction on this connection.

Implements ledger::core::api::DatabaseConnection.

close()

void Connection::close ( )

inlineoverridevirtual

Close the current connection. After this call the connection should never be called again.

Implements ledger::core::api::DatabaseConnection.

commit()

void Connection::commit ( )

inlineoverridevirtual

End the current transaction and persist all changes that occurred between the call of begin and commit.

Implements ledger::core::api::DatabaseConnection.

newBlob()

std::shared_ptr<api::DatabaseBlob> Connection::newBlob ( )

inlineoverridevirtual

Create a new empty blob.

Returns

An empty blob

Implements ledger::core::api::DatabaseConnection.

prepareStatement()

std::shared_ptr<api::DatabaseStatement> Connection::prepareStatement ( const std::string &  query, bool  repeatable  )

inlineoverridevirtual

Prepare a statement object using the given SQL query. The statement object will then be responsible of executing the query and handle results. Statement objects may be reused over time if their repeatable flag is set to true.

Parameters

query	A SQL query to execute (e.g. "SELECT * FROM users WHERE name = 'Joe'")
repeatable	A flag to indicate whether or not the statement is repeatable

Implements ledger::core::api::DatabaseConnection.

rollback()

void Connection::rollback ( )

inlineoverridevirtual

End the current transaction and rollback all changes that occurred between the call of begin and rollback.
