  • Method Details

    • 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:

See WorkGroupConfiguration$EnforceWorkGroupConfiguration.

    • 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.

    • toBuilder

      public StartQueryExecutionRequest.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<StartQueryExecutionRequest.Builder,StartQueryExecutionRequest>
      Specified by:
      toBuilder in class AthenaRequest
      Returns:
      a builder for type T

    • builder

      public static StartQueryExecutionRequest.Builder builder()

    • serializableBuilderClass

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

    • hashCode

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

    • equals

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

    • 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)
      Description copied from class: SdkRequest
      Used to retrieve the value of a field from any class that extends SdkRequest. The field name specified should match the member name from the corresponding service-2.json model specified in the codegen-resources folder for a given service. The class specifies what class to cast the returned value to. If the returned value is also a modeled class, the SdkRequest.getValueForField(String, Class) method will again be available.
      Overrides:
      getValueForField in class SdkRequest
      Parameters:
      fieldName - The name of the member to be retrieved.
      clazz - The class to cast the returned object to.
      Returns:
      Optional containing the casted return value

    • 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.
