Question

我需要通过电子邮件发送的sql查询结果采用可读形式。更改html将允许在表中创建结果。我需要在下面的代码中实现html的帮助。

USE msdb
go

SET QUOTED_IDENTIFIER OFF
SET ANSI_NULLS ON

IF EXISTS (select Kod, Nazwa from DATABASE.dbo.Towar where Kod NOT LIKE '%?%' and AsId IN (205, 304, 289, 321, 306, 217, 261) and Aktywny = 1)
BEGIN
    EXEC sp_send_dbmail @profile_name='PROFILE',
        @recipients='myadres@email.com',
        @query_result_header=0,
        @attach_query_result_as_file=0,
        @query="select Kod, Nazwa from DATABASE.dbo.Towar where Kod NOT LIKE '%?%' and AsId IN (205, 304, 289, 321, 306, 217, 261) and Aktywny=1 ORDER BY Kod",
        @body_format='text',
        @subject='warning';
END;

GO

“ MgSam”帖子Convert a SQL query result table to an HTML table for email中包含的示例实际上解决了转换为html和创建表的问题。但是，我不知道如何实现'if'条件。

根据MgSam准则，以下代码有效-但如果查询未返回数据，则发送电子邮件。

SET QUOTED_IDENTIFIER OFF
SET ANSI_NULLS ON

DECLARE @html nvarchar(MAX);

EXEC spQueryToHtmlTable @html = @html OUTPUT,  @query = "select Kod, Nazwa from DATABASE.dbo.Towar where Kod NOT LIKE '%?%' and AsId IN (205, 304, 289, 321, 306, 217, 261) and Aktywny = 1", @orderBy = N'ORDER BY Kod';

EXEC msdb.dbo.sp_send_dbmail
    @profile_name='PROFILE',
    @recipients='my@email.com',
    @subject = 'WARNING',
    @body = @html,
    @body_format = 'HTML',
    @query_no_truncate = 1,
    @attach_query_result_as_file = 0;

Answer 1

嗯，SQL Server中的IF语句非常简单，请在此处查看： https://docs.microsoft.com/en-us/sql/t-sql/language-elements/if-else-transact-sql

根据您的示例：

SET QUOTED_IDENTIFIER OFF
SET ANSI_NULLS ON

DECLARE @html nvarchar(MAX);

EXEC spQueryToHtmlTable @html = @html OUTPUT,  @query = "select Kod, Nazwa from DATABASE.dbo.Towar where Kod NOT LIKE '%?%' and AsId IN (205, 304, 289, 321, 306, 217, 261) and Aktywny = 1", @orderBy = N'ORDER BY Kod';

IF DATALENGTH(@html) > 0 
  EXEC msdb.dbo.sp_send_dbmail
    @profile_name='PROFILE',
    @recipients='my@email.com',
    @subject = 'WARNING',
    @body = @html,
    @body_format = 'HTML',
    @query_no_truncate = 1,
    @attach_query_result_as_file = 0;
ELSE PRINT 'No results, don't email';

Answer 2

我使用了 IF EXISTS 。有效的代码。

SET QUOTED_IDENTIFIER OFF
SET ANSI_NULLS ON

DECLARE @html nvarchar(MAX);

IF EXISTS (select Kod, Nazwa from DATABASE.dbo.Towar where Kod NOT LIKE '%?%' and AsId IN (205, 304, 289, 321, 306, 217, 261) and Aktywny = 1)

BEGIN

EXEC spQueryToHtmlTable @html = @html OUTPUT,  @query = "select Kod, Nazwa from DATABASE.dbo.Towar where Kod NOT LIKE '%?%' and AsId IN (205, 304, 289, 321, 306, 217, 261) and Aktywny = 1", @orderBy = N'ORDER BY Kod';

 EXEC msdb.dbo.sp_send_dbmail
    @profile_name='PROFILE',
    @recipients='my@email.com',
    @subject = 'WARNING',
    @body = @html,
    @body_format = 'HTML',
    @query_no_truncate = 1,
    @attach_query_result_as_file = 0;
    END;

GO

将查询输出格式化为html表
