queryTimeSeriesDatabase

Queries the time series data using SQL and AWS Timestream features.

The result will be paginated if large enough. For the first request, omit the nextToken and clientToken parameters or set them to None. If a NextToken is present in the query result, there is more data to retrieve. In subsequent requests use the original queryString and maxRows parameters, and the nextToken and clientToken from the previous query result.

Input variables begin with lowercase letters for Digital Exchange API consistency but result variables from AWS Timestream will have capitalized variable names.

Parameters

timeSeriesDbId :  str, required
    The id of the database.
queryString :  str, required
    The query to be run.
    The database table must be referenced as "{databaseName}"."{tableName}" (ex. 'SELECT...FROM "{databaseName}"."{tableName}"'). The databaseName and tableName can be found in the TimeSeriesDb object.
maxRows :  str, optional
    The maximum number of data rows to include in the query result.
nextToken :  str, optional
    A token that will retrieve the next set of data in a paginated result.

databaseName = db.databaseName
tableName = db.tableName

queryString = 'SELECT.....FROM "{databaseName}"."{tableName}" WHERE.....'

result = digitalExchange.queryTimeSeriesDatabase("{timeSeriesDbId}", "{queryString}", 100, "{nextToken}", "{clientToken}")
clientToken = result.clientToken
nextToken = result.NextToken
