Send Email from SQL Server database with multiple tables in email body

问题

I am challenged by the following task.

Here is my question in detail: I need to send email from SQL Server with HTML table format that the email body will have several tables.

Query will be from database like

SELECT Field1, Field2, Field3 
FROM Table 
WHERE DateField >= Somedate

Field3 will be the factor to separate the tables, hence, the result will be grouped by Field3 values and put on separate tables

The email content will be more or less like the following (screenshot is attached)

Section: Field3 Value1      
Field   Field2  Field3
   1    AA      Value1
   2    BB      Value1
   3    CC      Value1

Section: Field3 Value2      
Field   Field2  Field3
   1    OO      Value2
   2    XX      Value2
   3    VV      Value2

Section: Field3 Value3      
Field   Field2  Field3
   1    qwqw    Value3
   2    GGGG    Value3
   3    COCO    Value3

I have tried cursor, however, it will only return only one of the tables (based on the first FETCH value). Any help is appreciated

回答1:

Using the function I provide here you can do this:

DECLARE @tbl TABLE(Field1 INT, Field2 VARCHAR(10), Field3 VARCHAR(10));
INSERT INTO @tbl VALUES
 (1,'AA','Value1')
,(2,'BB','Value1')
,(3,'CC','Value1')
,(1,'OO','Value2')
,(2,'XX','Value2')
,(3,'VV','Value2')
,(1,'qwqw','Value3')
,(2,'GGGG','Value3')
,(3,'COCO','Value3');

--The query will build this as one big XHTML

SELECT (SELECT N'Section: Field3="Value1"' AS p FOR XML PATH(''),TYPE)
,dbo.CreateHTMLTable
        (
        (SELECT * FROM @tbl WHERE Field3='Value1' FOR XML PATH('row'), ELEMENTS XSINIL)
        ,NULL,NULL,NULL
        )
,(SELECT N'Section: Field3="Value2"' AS p FOR XML PATH(''),TYPE)
,dbo.CreateHTMLTable
        (
        (SELECT * FROM @tbl WHERE Field3='Value2' FOR XML PATH('row'), ELEMENTS XSINIL)
        ,NULL,NULL,NULL
        )
,(SELECT N'Section: Field3="Value3"' AS p FOR XML PATH(''),TYPE)
,dbo.CreateHTMLTable
        (
        (SELECT * FROM @tbl WHERE Field3='Value3' FOR XML PATH('row'), ELEMENTS XSINIL)
        ,NULL,NULL,NULL
        )  
FOR XML PATH('body'),ROOT('html');

This is the result (click run code snippet to see the result formatted)

    <p>Section: Field3="Value1"</p>
