Synopsis

Calls the Amazon Timestream Query Query API operation.

Syntax

Invoke-TSQQuery
-QueryString <String>
-MaxRow <Int32>
-ClientToken <String>
-NextToken <String>
-Select <String>
-PassThru <SwitchParameter>
-NoAutoIteration <SwitchParameter>

Description

Query is a synchronous operation that enables you to run a query against your Amazon Timestream data. Query will time out after 60 seconds. You must update the default timeout in the SDK to support a timeout of 60 seconds. See the code sample for details. Your query request will fail in the following cases:
  • If you submit a Query request with the same client token outside of the 5-minute idempotency window.
  • If you submit a Query request with the same client token, but change other parameters, within the 5-minute idempotency window.
  • If the size of the row (including the query metadata) exceeds 1 MB, then the query will fail with the following error message: Query aborted as max page response size has been exceeded by the output result row
  • If the IAM principal of the query initiator and the result reader are not the same and/or the query initiator and the result reader do not have the same query string in the query requests, the query will fail with an Invalid pagination token error.


This cmdlet automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. To disable autopagination, use -NoAutoIteration.

Parameters

-ClientToken <String>
Unique, case-sensitive string of up to 64 ASCII characters specified when a Query request is made. Providing a ClientToken makes the call to Queryidempotent. This means that running the same query repeatedly will produce the same result. In other words, making multiple identical Query requests has the same effect as making a single request. When using ClientToken in a query, note the following:
  • If the Query API is instantiated without a ClientToken, the Query SDK generates a ClientToken on your behalf.
  • If the Query invocation only contains the ClientToken but does not include a NextToken, that invocation of Query is assumed to be a new query run.
  • If the invocation contains NextToken, that particular invocation is assumed to be a subsequent invocation of a prior call to the Query API, and a result set is returned.
  • After 4 hours, any request with the same ClientToken is treated as a new request.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-MaxRow <Int32>
The total number of rows to be returned in the Query output. The initial run of Query with a MaxRows value specified will return the result set of the query in two cases:
  • The size of the result is less than 1MB.
  • The number of rows in the result set is less than the value of maxRows.
Otherwise, the initial invocation of Query only returns a NextToken, which can then be used in subsequent calls to fetch the result set. To resume pagination, provide the NextToken value in the subsequent command.If the row size is large (e.g. a row has many columns), Timestream may return fewer rows to keep the response size from exceeding the 1 MB limit. If MaxRows is not provided, Timestream will send the necessary number of rows to meet the 1 MB limit.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesMaxRows
-NextToken <String>
A pagination token used to return a set of results. When the Query API is invoked using NextToken, that particular invocation is assumed to be a subsequent invocation of a prior call to Query, and a result set is returned. However, if the Query invocation only contains the ClientToken, that invocation of Query is assumed to be a new query run. Note the following when using NextToken in a query:
  • A pagination token can be used for up to five Query invocations, OR for a duration of up to 1 hour – whichever comes first.
  • Using the same NextToken will return the same set of records. To keep paginating through the result set, you must to use the most recent nextToken.
  • Suppose a Query invocation returns two NextToken values, TokenA and TokenB. If TokenB is used in a subsequent Query invocation, then TokenA is invalidated and cannot be reused.
  • To request a previous result set from a query after pagination has begun, you must re-invoke the Query API.
  • The latest NextToken should be used to paginate until null is returned, at which point a new NextToken should be used.
  • If the IAM principal of the query initiator and the result reader are not the same and/or the query initiator and the result reader do not have the same query string in the query requests, the query will fail with an Invalid pagination token error.

Note: This parameter is only used if you are manually controlling output pagination of the service API call.
In order to manually control output pagination, use '-NextToken $null' for the first call and '-NextToken $AWSHistory.LastServiceResponse.NextToken' for subsequent calls.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NoAutoIteration <SwitchParameter>
By default the cmdlet will auto-iterate and retrieve all results to the pipeline by performing multiple service calls. If set, the cmdlet will retrieve only the next 'page' of results using the value of NextToken as the start point.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the QueryString parameter. The -PassThru parameter is deprecated, use -Select '^QueryString' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-QueryString <String>
The query to be run by Timestream.
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'Rows'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.TimestreamQuery.Model.QueryResponse). Specifying the name of a property of type Amazon.TimestreamQuery.Model.QueryResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
