Class StartQueryExecutionRequest

    • Method Detail

      • queryString

        public final String queryString()

        The SQL query statements to be executed.

        Returns:
        The SQL query statements to be executed.
      • clientRequestToken

        public final String clientRequestToken()

        A unique case-sensitive string used to ensure the request to create the query is idempotent (executes only once). If another StartQueryExecution request is received, the same response is returned and another query is not created. An error is returned if a parameter, such as QueryString, has changed. A call to StartQueryExecution that uses a previous client request token returns the same QueryExecutionId even if the requester doesn't have permission on the tables specified in QueryString.

        This token is listed as not required because Amazon Web Services SDKs (for example the Amazon Web Services SDK for Java) auto-generate the token for users. If you are not using the Amazon Web Services SDK or the Amazon Web Services CLI, you must provide this token or the action will fail.

      • queryExecutionContext

        public final QueryExecutionContext queryExecutionContext()

        The database within which the query executes.

        Returns:
        The database within which the query executes.
      • resultConfiguration

        public final ResultConfiguration resultConfiguration()

        Specifies information about where and how to save the results of the query execution. If the query runs in a workgroup, then workgroup's settings may override query settings. This affects the query results location. The workgroup settings override is specified in EnforceWorkGroupConfiguration (true/false) in the WorkGroupConfiguration. See WorkGroupConfiguration$EnforceWorkGroupConfiguration.

        Returns:

      • workGroup

        public final String workGroup()

        The name of the workgroup in which the query is being started.

        Returns:
        The name of the workgroup in which the query is being started.
      • hasExecutionParameters

        public final boolean hasExecutionParameters()
        For responses, this returns true if the service returned a value for the ExecutionParameters 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.
      • executionParameters

        public final List<String> executionParameters()

        A list of values for the parameters in a query. The values are applied sequentially to the parameters in the query in the order in which the parameters occur.

        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 hasExecutionParameters() method.

        Returns:
        A list of values for the parameters in a query. The values are applied sequentially to the parameters in the query in the order in which the parameters occur.
      • resultReuseConfiguration

        public final ResultReuseConfiguration resultReuseConfiguration()

        Specifies the query result reuse behavior for the query.

        Returns:
        Specifies the query result reuse behavior for the query.
      • 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
