Azure Logic for getting data from SQL to FTP

问题

I've a task of taking data from SQL and uploading the data as a CSV file up to an FTP server.

Now I've done this for a single SQL row just fine. The problem I'm having is looping over all rows (foreach loop) and inserting these rows as the content of the CSV file. I've tried a FTP Create File Task inside a foreach loop, but I can only access a single row at a time to set as the file's content - I need all the rows!

Also to keep in mind is that these files will have 200k+ rows.

I could of course just write a C# console app for this but the ease at which I got this far without writing any code makes it seem like it will be a worthwhile endeavor.

We recently added "Table" primitive for this scenario, support in designer is still work in progress, but you can use it in code view.

In below scenario, I'm getting rows from a table in SQL Azure, producing an CSV with two columns using data from the SQL query (First Name, Last Name), then send it via e-mail.

"Get_rows": {
    "inputs": {
        "host": {
            "api": {
                "runtimeUrl": "https://logic-apis-southcentralus.azure-apim.net/apim/sql"
            },
            "connection": {
                "name": "@parameters('$connections')['sql']['connectionId']"
            }
        },
        "method": "get",
        "path": "/datasets/default/tables/@{encodeURIComponent(encodeURIComponent('[SalesLT].[Customer]'))}/items",
        "queries": {
            "$top": 10
        }
    },
    "runAfter": {},
    "type": "ApiConnection"
},
"tableCsv0": {
    "inputs": {
        "columns": [
            {
                "header": "First Name",
                "value": "@item()?['FirstName']"
            },
            {
                "header": "Last Name",
                "value": "@item()?['LastName']"
            }
        ],
        "format": "csv",
        "from": "@body('Get_rows')?['value']"
    },
    "runAfter": {
        "Get_rows": [
            "Succeeded"
        ]
    },
    "type": "Table"
},

So just following up to show how Derek's answer helped me with my problem to get a large number of rows to up to a file on an FTP server. I ended up using the output body of the Execute Stored Procedure action as the GetRows action was limited to 512 rows.

NOTE: As the Table action is not available in the designer, yet, do everything in the code viewer, opening the designer caused issues and deleted all my code at one point.

"actions": {
        "Create_file": {
            "inputs": {

                    },
                    "connection": {
                        "name": "@parameters('$connections')['ftp']['connectionId']"
                    }
