Types

type DbClient

type DbClient struct {
	// contains filtered or unexported fields
}

DbClient wraps over `sql.DB` and gives an interface to the database

func NewDbClient

func NewDbClient(ctx context.Context, connectionString string, onConnectionCallback DbConnectionCallback) (*DbClient, error)

func (*DbClient) AcquireSession

func (c *DbClient) AcquireSession(ctx context.Context) (sessionResult *db_common.AcquireSessionResult)

func (*DbClient) CacheClear

func (c *DbClient) CacheClear(ctx context.Context) error

CacheClear implements Client

func (*DbClient) CacheOff

func (c *DbClient) CacheOff(ctx context.Context) error

CacheOff implements Client

func (*DbClient) CacheOn

func (c *DbClient) CacheOn(ctx context.Context) error

CacheOn implements Client

func (*DbClient) Close

func (c *DbClient) Close(context.Context) error

Close implements Client closes the connection to the database and shuts down the backend

func (*DbClient) ConnectionMap

func (c *DbClient) ConnectionMap() *steampipeconfig.ConnectionDataMap

func (*DbClient) ContructSearchPath

func (c *DbClient) ContructSearchPath(ctx context.Context, customSearchPath, searchPathPrefix []string) ([]string, error)

func (*DbClient) Execute

func (c *DbClient) Execute(ctx context.Context, query string) (*queryresult.Result, error)

Execute implements Client execute the query in the given Context NOTE: The returned Result MUST be fully read - otherwise the connection will block and will prevent further communication

func (*DbClient) ExecuteInSession

func (c *DbClient) ExecuteInSession(ctx context.Context, session *db_common.DatabaseSession, query string, onComplete func()) (res *queryresult.Result, err error)

ExecuteInSession implements Client execute the query in the given Context using the provided DatabaseSession ExecuteInSession assumes no responsibility over the lifecycle of the DatabaseSession - that is the responsibility of the caller NOTE: The returned Result MUST be fully read - otherwise the connection will block and will prevent further communication

func (*DbClient) ExecuteSync

func (c *DbClient) ExecuteSync(ctx context.Context, query string) (*queryresult.SyncQueryResult, error)

ExecuteSync implements Client execute a query against this client and wait for the result

func (*DbClient) ExecuteSyncInSession

func (c *DbClient) ExecuteSyncInSession(ctx context.Context, session *db_common.DatabaseSession, query string) (*queryresult.SyncQueryResult, error)

ExecuteSyncInSession implements Client execute a query against this client and wait for the result

func (*DbClient) ForeignSchemaNames

func (c *DbClient) ForeignSchemaNames() []string

ForeignSchemaNames implements Client

func (*DbClient) GetCurrentSearchPath

func (c *DbClient) GetCurrentSearchPath(ctx context.Context) ([]string, error)

GetCurrentSearchPath implements Client query the database to get the current session search path

func (*DbClient) GetCurrentSearchPathForDbConnection

func (c *DbClient) GetCurrentSearchPathForDbConnection(ctx context.Context, databaseConnection *sql.Conn) ([]string, error)

GetCurrentSearchPathForDbConnection queries the database to get the current session search path using the given connection

func (*DbClient) GetDefaultSearchPath

func (c *DbClient) GetDefaultSearchPath(ctx context.Context) []string

GetDefaultSearchPath builds default search path from the connection schemas, book-ended with public and internal

func (*DbClient) GetRequiredSessionSearchPath

func (c *DbClient) GetRequiredSessionSearchPath() []string

GetRequiredSessionSearchPath implements Client

func (*DbClient) GetSchemaFromDB

func (c *DbClient) GetSchemaFromDB(ctx context.Context) (*schema.Metadata, error)

GetSchemaFromDB requests for all columns of tables backed by steampipe plugins and creates golang struct representations from the result

func (*DbClient) LoadForeignSchemaNames

func (c *DbClient) LoadForeignSchemaNames(ctx context.Context) error

LoadForeignSchemaNames implements Client

func (*DbClient) RefreshConnectionAndSearchPaths

func (c *DbClient) RefreshConnectionAndSearchPaths(ctx context.Context) *steampipeconfig.RefreshConnectionResult

RefreshConnectionAndSearchPaths implements Client

func (*DbClient) RefreshSessions

func (c *DbClient) RefreshSessions(ctx context.Context) *db_common.AcquireSessionResult

RefreshSessions terminates the current connections and creates a new one - repopulating session data

func (*DbClient) SetRequiredSessionSearchPath

func (c *DbClient) SetRequiredSessionSearchPath(ctx context.Context) error

SetRequiredSessionSearchPath implements Client if either a search-path or search-path-prefix is set in config, set the search path (otherwise fall back to user search path) this just sets the required search path for this client - when creating a database session, we will actually set the searchPath

type DbConnectionCallback

type DbConnectionCallback func(context.Context, *pgx.Conn) error
