Description

This command executes data preview/stats preview/expression preview for different streams of data flow in debug session. The PowerShell command sequence for data flow debug workflow should be:

Start-AzSynapseDataFlowDebugSession Add-AzSynapseDataFlowDebugSessionPackage Invoke-AzSynapseDataFlowDebugSessionCommand (repeat this step for different commands/targets, or repeat step 2-3 in order to change the package file) Stop-AzSynapseDataFlowDebugSession

Examples

Example 1

$result = Invoke-AzSynapseDataFlowDebugSessionCommand -WorkspaceName ContosoWorkspace -Command executePreviewQuery -SessionId 3afb278e-ac5f-469f-a0b6-2f04c3ab59bc -StreamName source1 -RowLimit 100 -AsJob
$result | Format-Table -wrap

       for 'Invoke-AzSynapseD
       ataFlowDebugSessionCommand'

$output = ConvertFrom-Json($result.Output.Data)
$output.output

    {
      "schema": "output(ResourceAgencyNum as string, PublicName as string)" ,
      "data": [["4445679354", "Syrian Refugee Information", 1], ["44456793", "Syrian Refugee Information", 1]]
    }

This example invokes data preview command for debug session "3afb278e-ac5f-469f-a0b6-2f04c3ab59bc" in Synapse workspace "ContosoWorkspace" and then convert the JSON output into readable string.

Example 2

$ws = Get-AzSynapseWorkspace -Name ContosoWorkspace
$ws | Invoke-AzSynapseDataFlowDebugSessionCommand -Command executePreviewQuery -SessionId 3afb278e-ac5f-469f-a0b6-2f04c3ab59bc -StreamName source1 -RowLimit 100

This example invokes data preview command for debug session "3afb278e-ac5f-469f-a0b6-2f04c3ab59bc" in Synapse workspace "ContosoWorkspace" through pipeline.
