Added driver to support for Sql Server

[tjodalv]

I've created driver for the SQL server and updated readme file to document driver support.

I just notice that there is another pull request that adds support for SQL server. Still, I think this one is better because this one is using CONVERT SQLserver function to format date column and the other one is using FORMAT function which is slower and locale aware. Also the other pull request unnecessary refactor code in Trend service IMO.

I don't think this is working?

I tried your fork today and this is the SQL that was generated:

SELECT
  CONVERT(VARCHAR, created_at, 23) AS date,
  count(*) AS aggregate
FROM
  [ crm ].[ account_notes ]
WHERE
  [ created_at ] BETWEEN 2024 -03 -12 01: 59: 02.687
  AND 2024 -03 -19 01: 59: 02.687
GROUP BY
  [ CONVERT(VARCHAR, created_at, 23) ]
ORDER BY
  [ date ] ASC

Query 1 ERROR at Line 1: : Msg: 102, Line 7, State: 1, Level: 15 Incorrect syntax near '01'.

Manually fixed the query to be working:

SELECT
  CONVERT(VARCHAR, [created_at], 23) AS date,
  count(*) AS aggregate
FROM
  [crm].[account_notes]
WHERE
  [created_at] BETWEEN '2024-03-12 01:59:02.687'
  AND '2024-03-19 01:59:02.687'
GROUP BY
  CONVERT(VARCHAR, [created_at], 23)
ORDER BY
  [date] ASC

I removed spaces from inside the brackets, fixed the date strings, and removed the brackets from around the group by clause.

I've fixed the problem with groupBy clause when using SQL server driver and tested it against SQL Server 2022. It should work fine now.

[ryanmortier]

Working now, thanks!

SELECT
	CONVERT(VARCHAR, created_at, 23) AS date,
	count(*) AS aggregate
FROM
	[crm].[tickets]
WHERE
	[created_at] BETWEEN '2024-03-12 12:29:28.806'
	AND '2024-03-19 12:29:28.806'
GROUP BY
	CONVERT(VARCHAR, created_at, 23)
ORDER BY
	[date] ASC

Is there a way for you to wrap the column name in brackets in case it's a reserved word?

[tjodalv]

I've push latest commit that encloses date column name in square brackets.

I've push latest commit that encloses date column name in square brackets.

Tested and working great, thanks!

SELECT
	LEFT(CONVERT(VARCHAR, [add_date], 23), 7) AS date,
	sum(scale_quantity) AS aggregate
FROM
	[crm].[tickets]
WHERE
	[commodity_id] = 'corn'
	AND [add_date] BETWEEN '2023-03-19 20:35:42.983'
	AND '2024-03-19 20:35:42.983'
GROUP BY
	LEFT(CONVERT(VARCHAR, [add_date], 23), 7)
ORDER BY
	[date] ASC

@Larsklopstra can we have this reviewed and merged whenever you have a chance?

[ryanmortier]

I got looking at this again today and I started wondering if this could potentially be vulnerable to SQL injection if the developer for some reason accepted input for the ->dateColumn() method?
