Azure SQL Database - something like sp_send_dbmail

 I needed the ability to send emails from Azure SQL DB, which doesn't support it. The long-term goal is to use LogicApps or SendGrid or something like that, but while I wait for permissions and the like, let me share this instead. It acts like sp_send_dbmail, and will even run queries in the database (or other databases on that server!) and send them from your on-prem server.

This is based on others. They had the awesome parts, my parts are the crappy glue making it work. : )


The emailqueue table looks like this:

CREATE TABLE [dbo].[EmailQueue](
[Id] [INT] IDENTITY(1,1) NOT NULL,
[Recipients] [VARCHAR](250) NOT NULL,
[Cc_recipients] [VARCHAR](250) NULL,
[Email_Subject] [VARCHAR](250) NOT NULL,
[Email_body] [VARCHAR](MAX) NULL,
[Email_body_format] [VARCHAR](10) NULL,
[Query] [NVARCHAR](MAX) NULL,
[profile_name] [VARCHAR](250) NULL,
[QueueTime] [DATETIME2](7) NOT NULL,
[SentTime] [DATETIME2](7) NULL,
[Importance] [VARCHAR](10) NULL,
[attach_query_result_as_file] [BIT] NULL,
[query_attachment_filename] [VARCHAR](200) NULL,
[query_result_header] [BIT] NULL,
[query_result_width] [INT] NULL,
[query_result_separator] [VARCHAR](2) NULL,
[query_result_no_padding] [BIT] NULL,
[bcc_recipients] [VARCHAR](255) NULL,
[execute_query_database] [VARCHAR](255) NULL,
[from_address] [VARCHAR](MAX) NULL,
PRIMARY KEY CLUSTERED 
(
[Id] ASC
)WITH (STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, OPTIMIZE_FOR_SEQUENTIAL_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO
ALTER TABLE [dbo].[EmailQueue] ADD  CONSTRAINT [Co_Importance]  DEFAULT ('Normal') FOR [Importance]
GO
ALTER TABLE [dbo].[EmailQueue] ADD  DEFAULT ((0)) FOR [attach_query_result_as_file]
GO
ALTER TABLE [dbo].[EmailQueue] ADD  DEFAULT ((1)) FOR [query_result_header]
GO
ALTER TABLE [dbo].[EmailQueue] ADD  DEFAULT ((0)) FOR [query_result_no_padding]
GO


And the SP:

Xquery - a surprising difference between Azure SQL Database and Azure Managed Instance with Quotes

I'm moving processes into Azure.  Given that it's me, probably poorly. But I'm using this as an opportunity to improve things where possible, specifically looking at moving some processes to Azure SQL Database. 
Why? I love them for several reasons: 

  • Simpler
  • Cheaper
  • Quick to create
  • Quick to modify the instance (seconds, not hours)


Yes, there are still gotchas (Elastic Jobs, no cross-db queries, no CLR, can't replicate from it), but overall? Soooo nice.

---

I was trying to get some Xquery parsing working, and ran into a weird error:
"CONDITIONAL failed because the following SET options have incorrect settings: 'QUOTED_IDENTIFIER'"

Weird.  Doubly so because this code has worked on-prem for a decade, and the Managed Instance is running it now.  And because the SP specifically has a SET QUOTED_IDENTIFIER ON; 

Okay, let's take alook online.


Yeah, that's the problem.  And indeed, my code has similar xquery to the example:
set @myval = @xml.[value]('(*/A[B="C"]/D[E="F" or G="H"]/I)[1]', 'varchar (35)');

What's the fix? Use two single-quotes instead of the double quote.
set @myval = @xml.[value]('(*/A[B=''C'']/D[E=''F'' or G=''H'']/I)[1]', 'varchar (35)');
