Member Function Documentation

QString spatialite_database_unique_ptr::errorMessage

(

)

const

Returns the most recent error message encountered by the database.

Definition at line 60 of file qgsspatialiteutils.cpp.

int spatialite_database_unique_ptr::open

(

const QString &

path

)

Opens the database at the specified file path.

Returns the sqlite error code, or SQLITE_OK if open was successful.

Definition at line 25 of file qgsspatialiteutils.cpp.

int spatialite_database_unique_ptr::open_v2	(	const QString &	path,
		int	flags,
		const char *	zVfs
	)

Opens the database at the specified file path.

Returns the sqlite error code, or SQLITE_OK if open was successful.

Definition at line 45 of file qgsspatialiteutils.cpp.

sqlite3_statement_unique_ptr spatialite_database_unique_ptr::prepare	(	const QString &	sql,
		int &	resultCode
	)

Prepares a sql statement, returning the result.

The resultCode argument will be filled with the sqlite3 result code.

Definition at line 65 of file qgsspatialiteutils.cpp.

void spatialite_database_unique_ptr::reset

(

)

Will close the connection and set the internal pointer to nullptr.

Definition at line 40 of file qgsspatialiteutils.cpp.

void spatialite_database_unique_ptr::reset ( sqlite3 *  handle )

delete

It is not allowed to set an arbitrary sqlite3 handle on this object.

A dedicated spatialite context (connection) is created when calling open or open_v2. This context needs to be kept together with the handle, hence it is not allowed to reset to a handle with missing context.
