I am running a SQL query that returns a table of results. I want to send the table in an email using dbo.sp_send_dbMail.
Is there a straightforward way within SQL to turn a table into an HTML table? Currently, I'm manually constructing it using COALESCE and putting the results into a varchar that I use as the emailBody.
Is there a better way to do this?
I made a dynamic proc which turns any random query into an HTML table, so you don't have to hardcode columns like in the other responses.
-- Description: Turns a query into a formatted HTML table. Useful for emails.
-- Any ORDER BY clause needs to be passed in the separate ORDER BY parameter.
-- =============================================
CREATE PROC [dbo].[spQueryToHtmlTable]
(
@query nvarchar(MAX), --A query to turn into HTML format. It should not include an ORDER BY clause.
@orderBy nvarchar(MAX) = NULL, --An optional ORDER BY clause. It should contain the words 'ORDER BY'.
@html nvarchar(MAX) = NULL OUTPUT --The HTML output of the procedure.
)
AS
BEGIN
SET NOCOUNT ON;
IF @orderBy IS NULL BEGIN
SET @orderBy = ''
END
SET @orderBy = REPLACE(@orderBy, '''', '''''');
DECLARE @realQuery nvarchar(MAX) = '
DECLARE @headerRow nvarchar(MAX);
DECLARE @cols nvarchar(MAX);
SELECT * INTO #dynSql FROM (' + @query + ') sub;
SELECT @cols = COALESCE(@cols + '', '''''''', '', '''') + ''['' + name + ''] AS ''''td''''''
FROM tempdb.sys.columns
WHERE object_id = object_id(''tempdb..#dynSql'')
ORDER BY column_id;
SET @cols = ''SET @html = CAST(( SELECT '' + @cols + '' FROM #dynSql ' + @orderBy + ' FOR XML PATH(''''tr''''), ELEMENTS XSINIL) AS nvarchar(max))''
EXEC sys.sp_executesql @cols, N''@html nvarchar(MAX) OUTPUT'', @html=@html OUTPUT
SELECT @headerRow = COALESCE(@headerRow + '''', '''') + ''<th>'' + name + ''</th>''
FROM tempdb.sys.columns
WHERE object_id = object_id(''tempdb..#dynSql'')
ORDER BY column_id;
SET @headerRow = ''<tr>'' + @headerRow + ''</tr>'';
SET @html = ''<table border="1">'' + @headerRow + @html + ''</table>'';
';
EXEC sys.sp_executesql @realQuery, N'@html nvarchar(MAX) OUTPUT', @html=@html OUTPUT
END
GO
Usage:
DECLARE @html nvarchar(MAX);
EXEC spQueryToHtmlTable @html = @html OUTPUT, @query = N'SELECT * FROM dbo.People', @orderBy = N'ORDER BY FirstName';
EXEC msdb.dbo.sp_send_dbmail
@profile_name = 'Foo',
@recipients = '[email protected];',
@subject = 'HTML email',
@body = @html,
@body_format = 'HTML',
@query_no_truncate = 1,
@attach_query_result_as_file = 0;
