  1. Database project from Visual Studio to support Azure SQL Data Warehouse

    Database project from Visual Studio is useful to manage DDLs, schema compare between the project and database, etc. Please create a project template dedicated for DW or support DW development from Database Project.

      • PolyBase: allow escaping string delimiters within string fields

        If you want to quote the string columns, and if one of the quoted columns has a quote character in it, the proper way to encode this is to double the quote character. (Build a CSV file in Excel and you will see that's how it saves it. I would say Excel is the authority on CSV formats.)

        it appears it's impossible for Polybase to properly load that file. For example the following format is not interpreted right with STRING_DELIMITER = '"' since it divides the value 2.5" into two columns

        SizeDescription|SizeCode
        "3.5 feet"|"3.5 ft"
        "2.5 inches"|"2.5"""

        Please improve Polybase…

        • Row-Level Security

          It would be great to implement Row-Level Security on SQL Data Warehouse.
          That would be a great solution for scenarios where (for example) we have clients like PowerBI using data from SQL warehouse, and persons who have limited data access.

          • Polybase: allow field/row terminators within string fields

            If a line end is present within a text field (qualified) importing data using Polybase will fail.

            Loading this line will work fine:
            1;2.1;"zzzz"

            Loading this will fail:
            1;2.1;"zz
            zz"

            Code:

            CREATE EXTERNAL FILE FORMAT text_file_format_raw
            WITH
            (
            FORMAT_TYPE = DELIMITEDTEXT,
            FORMAT_OPTIONS
            (
            FIELD_TERMINATOR =';',
            STRING_DELIMITER = '0x22',
            USE_TYPE_DEFAULT = TRUE
            )
            );

            CREATE EXTERNAL TABLE dbo.test_external
            (
            col1 INT,
            col2 DECIMAL(2,1),
            col3 NVARCHAR(5)
            )
            WITH
            (
            LOCATION = 'test_failing.txt',
            DATA_SOURCE = azure_storage,
            FILE_FORMAT = text_file_format_raw
            );

            CREATE TABLE dbo.test
            WITH (CLUSTERED COLUMNSTORE INDEX, DISTRIBUTION = ROUND_ROBIN)
            AS
            SELECT * FROM dbo.test_external;

              • Support for Entity Framework

                Support for Entity Framework in Azure SQL Data Warehouse would allow for greater usability in general, but it would also allow for better support of other frameworks/protocols. Specifically, we have a need to serve our data through an OData feed, and Entity Framework's deferred execution would allow us to handle OData's Query Options in a much simpler way.

                          • ANSI joins support in UPDATE & DELETE statement

                            SQL DW does not support to usual way of joins (ANSI) in UPDATE, DELETE statement. This makes difficult in case of table data modification. Though there is a workaround provided for CTAS this seems to be a lengthy process of data modification. Please have this feature available in SQL DW.

                                Shrinkdatabase command should to be supported even if TDE is on or off because extra cost is charged in case that the unallocated space is huge.

                                    • User Defined Retention Periods for Restore Points (snapshots)

                                      Currently SQL DW doesn't have the capability to specify longer term retention capabilities as released for SQL DB recently. It would be great to have this capability for compliance and auditing requirements.

                                      • More flexible date formats in Polybase

                                        Polybase currently has very limited date format support. All of the acceptable date formats have dashes or slashes. For example, I can't define a date format of yyyyMMdd since it doesn't have slashes or dashes. Please allow any date format I can express.

                                        Also, please allow more than one date format per external table. For example, what if I have a date column as yyyyMMdd and then a different column as yyyyMMddHHmm. With only being able to define one date format in the CREATE EXTERNAL FILE FORMAT statement I think I can't handle both formats.

                                        • @@ROWCOUNT Support

                                          Please enable @@ROWCOUNT?

                                          Furthermore considering that we cannot switch NOCOUNT on, then why should it be such a secret/coded mission to track the number of rows affected by the most recent snippet of code? The proposed work-around seems onerous and doesn't always work (for dynamic SQL) yet my query window still knows and always-prints the fact that it returned 15 rows to me, for example, so why can we not leverage this elementary information inside the selfsame query (?):

                                          SELECT SUM(row_count) AS row_count
                                          FROM sys.dm_pdw_sql_requests
                                          WHERE row_count <> -1
                                          AND request_id IN
                                          ( SELECT TOP 1 request_id
                                          FROM sys.dm_pdw_exec_requests
                                          WHERE…
