The group of commands has global parameter '--debug' which means 'Increase logging verbosity to show all debug logs.'. The group of commands has global parameter '--help -h' which means 'Show this help message and exit.'. The group of commands has global parameter '--only-show-errors' which means 'Only show errors, suppressing warnings.'.

You can configure the default subscription using `az account set -s NAME_OR_ID`.'. The group of commands has global parameter '--verbose' which means 'Increase logging verbosity. Use --debug for full debug logs.'. This group contains a child command 'az_stream analytics_transformation_create'.The syntax is: az stream-analytics transformation create --job-name
                                          --name
                                          --resource-group
                                          [--if-match]
                                          [--if-none-match]

                                          [--streaming-units]
                                          [--valid-streaming-units]. The 1th example of the child command would be to use it to 'create a transformation', the syntax is: az stream-analytics transformation create --job-name "sj8374" --resource-group "sjrg4423" --saql "Select Id, Name from inputtest" --streaming-units 6 --transformation-name "transformation952". The parameter '--job-name' is required. It is used to the name of the streaming job.. The parameter '--name --transformation-name -n' is required. It is used to the name of the transformation.. The parameter '--resource-group -g' is required. It is used to name of resource group. you can configure the default group using `az configure --defaults group=<name>`.. The parameter '--if-match' is optional. the etag of the transformation. omit this value to always overwrite the current transformation. specify the last-seen etag value to prevent accidentally overwriting concurrent changes.. The parameter '--if-none-match' is optional. set to '*' to allow a new transformation to be created, but to prevent updating an existing transformation. other values will result in a 412 pre-condition failed response.. The parameter '--saql' is optional. specifies the query that will be run in the streaming job. you can learn more about the stream analytics query language (saql) here: https://msdn.microsoft.com/library/azure/dn834998 . required on put (createorreplace) requests.. The parameter '--streaming-units' is optional. specifies the number of streaming units that the streaming job uses.. The parameter '--valid-streaming-units' is optional. specifies the valid streaming units a streaming job can scale to..
