Azure Logic Apps'执行SQL查询'连接器

Question

I am trying to implement several Azure Logic Apps that query/update an Azure SQL Server Database. The queries return either one value or a table with several rows. I prefer not to create stored procedures, but instead use the 'Execute SQL Query' Connector. My queries are running fine in the Logic Apps, but I have not found a way to extract the output of the queries to use in next steps, or return in an HTTP Response.

Can someone guide me on how this can be done for both single-value and table outputs?

Answer 1

If for some reason you don't want to create a SP, or cannot do it, you can access your custom query results by using this in your JSON:

@body('Name_of_Execute_SQL_Query_step')?['resultsets']['Table1'][0]['NameOfYourColumn']

If you can't find the exact "path" for your data, run and let it fail. Then go check the failing step and there in "Show raw outputs" you will be able to see the results of the Execute SQL Query step. For example:

{
  "OutputParameters": {},
  "ResultSets": {
    "Table1": [
      {
        "Date": "2018-05-28T00:00:00"
      }
    ]
  }
}

To access that date, you'd of course need to use:

@body('Name_of_Execute_SQL_Query_step')?['resultsets']['Table1'][0]['Date']

Stored Procedures are always better for many reasons and the output can be reasonable well inferred by the Connector. That's why Stored Procedure output lights up in the designer.

Execute SQL Actions return 'untyped' content which is why you don't see specific elements in the designer.

To use the Execute SQL output like a Stored Procedure output, you would have to define the JSON Schema yourself, and use the Parse JSON Action to light up the SQL output.
