Class CustomSql

    • Method Detail

      • dataSourceArn

        public final String dataSourceArn()

        The Amazon Resource Name (ARN) of the data source.

        Returns:
        The Amazon Resource Name (ARN) of the data source.
      • name

        public final String name()

        A display name for the SQL query result.

        Returns:
        A display name for the SQL query result.
      • sqlQuery

        public final String sqlQuery()

        The SQL query.

        Returns:
        The SQL query.
      • hasColumns

        public final boolean hasColumns()
        For responses, this returns true if the service returned a value for the Columns property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
      • columns

        public final List<InputColumn> columns()

        The column schema from the SQL query result set.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasColumns() method.

        Returns:
        The column schema from the SQL query result set.
      • hashCode

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

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