Unsupported data type - uuid

Following issue #771 I run some additional test and I found that all the following commented columns have data types that are not support in DAB yet.

drop table if exists dbo.datatypetest;

create table dbo.datatypetest
(
    id int not null primary key,
    --a_time time(7) not null,
    a_date date not null,
    a_datetime datetime not null,
    a_datetime2 datetime2(7) not null,
    --a_datetimeoffset datetimeoffset not null,
    --a_guid uniqueidentifier not null  
)
go

insert into dbo.datatypetest 
    (
        id
        --,a_time
        ,a_date
        ,a_datetime
        ,a_datetime2
        --,a_datetimeoffset
        --,a_guid
    )
    values
    (
        1
        --,sysutcdatetime() 
        ,sysutcdatetime()
        ,sysutcdatetime() 
        ,sysutcdatetime() 
        --,sysdatetimeoffset()
        --,newid()
    )
go

select * from dbo.datatypetest

those a very common data types and thus supporting them is critical. I’m closing #771 as this is more generic.

Order of priority for supporting the missing data types:

P0

• UNIQUEIDENTIFIER

P1

• JSON
  • for Azure SQL DB as described in https://github.com/Azure/data-api-builder/issues/444
  • for PostgreSQL using the native JSON type (or JSONB: I’ll let PostgreSQL PM and experts decide what is better)
  • for MariaDB/MySQL I don’t know if there is native JSON type support, so also here I’ll defer the decision to MySQL/MariaDB PM/Experts

P2

• Time
• DateTimeOffset

This is a known issue - previously reported in #177. We can try to accommodate few of these, but its quite possible this may have to be pushed to Oct. Depending on @gledis69 availability to work on this in September.
