Method Detail

dialect

public final ViewDialect dialect()

The dialect of the query engine.

If the service returns an enum value that is not available in the current SDK version, dialect will return ViewDialect.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from dialectAsString().

Returns:

The dialect of the query engine.

ViewDialect

dialectAsString

public final String dialectAsString()

The dialect of the query engine.

If the service returns an enum value that is not available in the current SDK version, dialect will return ViewDialect.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from dialectAsString().

Returns:

The dialect of the query engine.

See Also:

ViewDialect

dialectVersion

public final String dialectVersion()

The version of the dialect of the query engine. For example, 3.0.0.

Returns:

The version of the dialect of the query engine. For example, 3.0.0.

viewOriginalText

public final String viewOriginalText()

The SELECT query provided by the customer during CREATE VIEW DDL. This SQL is not used during a query on a view (ViewExpandedText is used instead). ViewOriginalText is used for cases like SHOW CREATE VIEW where users want to see the original DDL command that created the view.

Returns:

The SELECT query provided by the customer during CREATE VIEW DDL. This SQL is not used during a query on a view (ViewExpandedText is used instead). ViewOriginalText is used for cases like SHOW CREATE VIEW where users want to see the original DDL command that created the view.

viewExpandedText

public final String viewExpandedText()

The expanded SQL for the view. This SQL is used by engines while processing a query on a view. Engines may perform operations during view creation to transform ViewOriginalText to ViewExpandedText. For example:

• Fully qualified identifiers: SELECT * from table1 -> SELECT * from db1.table1

Returns:

The expanded SQL for the view. This SQL is used by engines while processing a query on a view. Engines may perform operations during view creation to transform ViewOriginalText to ViewExpandedText. For example:

• Fully qualified identifiers: SELECT * from table1 -> SELECT * from db1.table1

validationConnection

public final String validationConnection()

The name of the connection to be used to validate the specific representation of the view.

Returns:

The name of the connection to be used to validate the specific representation of the view.

isStale

public final Boolean isStale()

Dialects marked as stale are no longer valid and must be updated before they can be queried in their respective query engines.

Returns:

Dialects marked as stale are no longer valid and must be updated before they can be queried in their respective query engines.
