@Generated("software.amazon.awssdk:codegen") public final class ViewRepresentation extends Object implements SdkPojo, Serializable, ToCopyableBuilder<ViewRepresentation.Builder,ViewRepresentation>

A structure that contains the dialect of the view, and the query that defines the view.

  • Method Details

    • 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.
      See Also:

    • 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:

    • 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.

    • toBuilder

      public ViewRepresentation.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<ViewRepresentation.Builder,ViewRepresentation>
      Returns:
      a builder for type T

    • builder

      public static ViewRepresentation.Builder builder()

    • serializableBuilderClass

      public static Class<? extends ViewRepresentation.Builder> serializableBuilderClass()

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class Object

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.
